HESI Fundamentals - Set 2 - Part 1

Correct Answer: Soap and water for twenty seconds

Soap and water for at least twenty seconds is required when spore-forming organisms are suspected. Alcohol rub does not kill bacterial spores, so mechanical removal through scrubbing and rinsing is essential here. Option a is incorrect because Alcohol rub does not kill bacterial spores, so it leaves the nurse contaminated despite feeling clean. Spore-forming pathogens require physical removal through soap and friction, not chemical kill alone after exposure. Option b is incorrect because A quick water rinse without soap removes very little bacteria and no spores. Effective hand hygiene with these organisms requires friction with soap and full lathering of hands followed by careful rinsing. Option d is incorrect because Hand wipes do not provide adequate spore removal and gloves are not a substitute for hygiene. Wearing gloves over contaminated hands recontaminates the next patient when gloves are removed without first washing.

Correct Answer: Hands not visibly soiled between patient contacts

Alcohol-based hand rub is preferred when hands are not visibly soiled and routine activity occurs between contacts. The product is fast, well tolerated, and effective against most common pathogens encountered on the unit. Option b is incorrect because Visibly soiled hands require soap and water because alcohol rub does not remove organic material. The dirt and body fluid must be physically washed away before any antimicrobial product can be effective. Option c is incorrect because After spore-forming infection care, soap and water are required because alcohol does not kill spores. The mechanical scrubbing and rinsing physically remove spores that the alcohol product cannot inactivate. Option d is incorrect because Before eating, soap and water are recommended for clean removal of any organic residue. The process is also a good opportunity to fully wash, since the nurse is leaving the clinical area.

Correct Answer: Before touching the patient at the bedside

Hand hygiene before patient contact is the first of the five moments and protects the patient from organisms carried on the nurse's hands. The action prevents introduction of new pathogens during direct care. Option a is incorrect because Leaving the cafeteria is not one of the five moments, although clean hands are always good practice. The moments specifically apply to patient care interactions in the clinical setting, not personal activities outside. Option b is incorrect because Signing into a charting computer is not specifically one of the five moments, though hands frequently touch shared keyboards. The five moments focus on patient-centered timing rather than incidental computer use. Option c is incorrect because Walking into the supply room does not match any of the five named moments. The five-moment system targets points of contact directly relevant to the patient and the immediate clinical environment.

Correct Answer: Twenty seconds of vigorous friction minimum

At least twenty seconds of vigorous friction with soap is the standard hand washing technique. The friction loosens organic material and pathogens so they can be rinsed away effectively under running water. Option a is incorrect because Five seconds is far too short and does not loosen organic material or microbes from skin. Hand washing at that duration provides only token cleaning and does not meaningfully reduce pathogen burden present. Option c is incorrect because Ten seconds is below the recommended minimum and skipping rinsing leaves loosened debris on the skin. Both elements together are unsafe; full rinsing with adequate friction time is required for effective washing. Option d is incorrect because Sixty seconds is longer than required for routine washing and may dry the skin unnecessarily. Twenty seconds is the standard for routine; longer durations are reserved for specific surgical scrub procedures.

Correct Answer: Wash hands with soap and water

Soap and water with friction physically remove C. difficile spores from the hands. Alcohol rub does not kill spores, so the mechanical action of washing is the only effective hygiene step after care. Option a is incorrect because Alcohol rub does not kill bacterial spores produced by C. difficile, regardless of contact time. The nurse may feel clean but the spores remain on the hands and can be transferred to the next patient. Option b is incorrect because Skipping hygiene because gloves were worn is unsafe; gloves can develop micro-tears and contaminate hands during removal. Hand hygiene is required after every glove use, not just when gloves were absent. Option d is incorrect because Antiseptic wipes are not validated for spore removal and lack the friction provided by hand washing. The nurse should use soap and water at the sink to physically remove the spores before continuing.

Correct Answer: Gown, mask, eye protection, then gloves

The standard donning sequence is gown, mask, eye protection, and finally gloves. This order ensures that gloves cover gown cuffs and that respiratory protection is in place before entering the patient room. Option b is incorrect because Putting gloves on first would mean the rest of the equipment cannot be donned cleanly. Gloves go on last so they can cover the gown wrist cuff and remain intact during patient care. Option c is incorrect because Eye protection before gloves disrupts the standard sequence and risks contamination. The full body coverage from the gown should be in place first, then face protection, then gloves over the gown. Option d is incorrect because Putting gloves on before the gown means the gloves cannot be tucked under the gown cuff. This sequence leaves a gap at the wrist that can expose the nurse to body fluids during care.

Correct Answer: Gloves are removed before everything else

Gloves are removed first because they are typically the most contaminated item. Removing gloves before any other equipment prevents the nurse from spreading pathogens onto the gown, face, or hair during doffing. Option a is incorrect because Removing the mask before gloves contaminates the face from the still-soiled gloves. The mask must wait until gloves and gown are off and the hands have been cleaned to prevent direct contamination. Option b is incorrect because Removing the gown before gloves means using contaminated gloves to handle the gown, which spreads pathogens. The proper order is gloves first, then gown, then eye protection, then mask, with hand hygiene between. Option c is incorrect because Eye protection before gloves means the soiled gloves touch the head and face. Eye protection is removed after gloves and gown so that hands are cleaner when reaching toward the eyes and forehead.

Correct Answer: Seal check by inhaling and exhaling fully

Seal check requires the wearer to inhale and exhale forcefully to confirm an airtight fit. The mask should pull in slightly on inhalation and not leak around the edges during exhalation when sealed. Option a is incorrect because Loose ear straps leave the mask unsealed against the face and let infectious aerosols bypass the filter. N95 respirators use elastic head straps rather than ear loops, and the straps must be snug. Option b is incorrect because Skipping the seal check defeats the purpose of fit testing and respiratory protection. A mask that feels tight may still leak, especially around the nose bridge or chin, so seal check is essential. Option d is incorrect because Using any mask available without fit testing fails the airborne precautions standard. N95 respirators must be fit tested to a specific size and model, and seal checked each time before entering the room.

Correct Answer: Replace the contaminated gown and start over

When a sterile gown contacts a non-sterile surface, the gown is contaminated. The nurse must replace the gown and resume the procedure with new sterile equipment, since recovery from a true break in technique requires replacement. Option a is incorrect because Continuing with a contaminated gown introduces pathogens into the wound. Wound infection risk rises sharply when sterile technique is broken; the procedure cannot continue safely without replacing the affected equipment first. Option c is incorrect because Wiping the gown with alcohol does not restore sterility, since clean is not the same as sterile. Once contaminated, the gown cannot be made sterile again at the bedside under any circumstance. Option d is incorrect because Covering the sleeve with a sterile drape does not disinfect the underlying contamination. The sleeve fabric will continue to harbor pathogens and may shed them onto the field during continued care work.

Correct Answer: Measles patient on airborne precautions

Measles travels by airborne route on small particles that linger in the air. Airborne precautions require an N95 or higher respirator, a private room with negative pressure, and limited unmasked entry into the room. Option b is incorrect because Influenza spreads by droplet, which falls quickly within about three feet of the source. Droplet precautions use a surgical mask, gloves, and gown when within close range of the patient during care. Option c is incorrect because Pertussis is transmitted by droplet, not airborne particles. A surgical mask is appropriate for droplet precautions and an N95 is not required for routine pertussis care under most policies and guidelines. Option d is incorrect because Not all three need N95; only the airborne organism does. Using N95 unnecessarily wastes resources and is not required when droplet protection alone is adequate for the route of transmission involved.

Correct Answer: Apply to every patient at all times

Standard precautions apply to every patient regardless of diagnosis or suspected infection. The approach assumes any blood, body fluid, or non-intact skin can transmit infection and therefore guides every routine encounter. Option a is incorrect because Visible blood is one trigger but not the only one. Standard precautions apply continuously because invisible body fluids, mucous membrane contact, and skin breaks all create transmission opportunities throughout daily nursing tasks. Option b is incorrect because Standard precautions apply universally and do not depend on isolation orders. Transmission-based precautions are the additional layer ordered for known or suspected pathogens, but standard precautions form the constant baseline. Option c is incorrect because Invasive procedures require additional precautions but standard precautions still apply during all routine care. Standard precautions cover hand hygiene, gloves, and other protections during everyday non-invasive activities

Correct Answer: Activate safety device, drop in container

Activating the engineered safety device and dropping the needle directly into the puncture-resistant container is the standard practice. The nurse never recaps and never passes uncapped needles between hands or between staff members. Option a is incorrect because Recapping needles is a leading cause of needlestick injuries because the nurse may miss the cap. Engineered safety devices on modern needles eliminate the need to recap and protect the user during disposal. Option b is incorrect because Placing used needles on a counter creates a hazard for the next person who walks by. Sharps must go directly into the puncture-resistant container at the point of use, not on shared surfaces. Option d is incorrect because Passing uncapped needles between staff increases the chance of injury during the handoff. The user who created the sharp must dispose of it personally rather than transferring the hazard to a coworker.

Correct Answer: Wash puncture site with soap and water

Washing the puncture site with soap and water is the recommended immediate action. Mucous membrane exposures are flushed with water or saline. Reporting to employee health follows so post-exposure prophylaxis can be considered. Option b is incorrect because Vigorous squeezing of the wound is not recommended and may cause additional tissue trauma. Standard guidance focuses on washing the area thoroughly rather than encouraging extensive bleeding through deliberate squeezing of the puncture site. Option c is incorrect because Applying a tourniquet is dangerous, unnecessary, and can cause limb ischemia. A tourniquet has no role in needlestick management and could harm the nurse rather than reducing the risk of disease transmission. Option d is incorrect because Waiting until end of shift delays the post-exposure assessment, baseline labs, and possible prophylaxis. Time matters because antiretroviral and other prophylactic therapies are most effective when started soon after exposure.

Correct Answer: Put soiled gauze in biohazard container

Saturated gauze with visible drainage goes into the labeled biohazard container so the medical waste stream handles it properly. The empty saline bottle and unsoiled wrappers can usually go into the regular trash. Option a is incorrect because Placing visibly contaminated waste in regular trash is inappropriate because regular waste streams are not designed to manage infectious material. The action also exposes housekeeping staff to bloodborne pathogens during normal trash handling. Option b is incorrect because Recycling unsoiled items can be appropriate when local policy supports it, but it does not address the saturated dressings. The biohazard container is still required for the visibly contaminated portion of the waste. Option c is incorrect because Mixing all waste in a single bin defeats the categorization that protects waste handlers and the environment. Different waste types follow different processing pathways for safety and regulatory compliance reasons every time.

Correct Answer: Disinfect high-touch surfaces with approved agent

Terminal cleaning includes disinfecting high-touch surfaces with an approved agent that targets the specific organism. Bed rails, call lights, doorknobs, faucets, and tray tables all need attention to prevent transmission to the next patient. Option a is incorrect because Vacuuming carpet alone misses the most contaminated high-touch surfaces in the room. Many MDROs are spread by hand contact with rails, switches, and equipment, and these areas require disinfection beyond floor cleaning. Option b is incorrect because Air freshener does nothing to reduce pathogen load on surfaces. Cosmetic improvements have no role in infection control compared to systematic disinfection of every high-touch surface using an EPA-registered agent. Option d is incorrect because Plain water does not disinfect surfaces or kill pathogens, regardless of how thoroughly it is applied. The product used must be selected for the suspected organism and used according to contact time directions.

Correct Answer: Contact precautions with gown and gloves

MRSA spreads through direct and indirect contact with skin and contaminated equipment. Contact precautions require a gown and gloves for any room entry that may involve patient contact or contact with the immediate environment. Option a is incorrect because Airborne precautions are not used for MRSA, which does not travel as fine respiratory aerosols. Reserving the negative-pressure room and N95 for organisms like tuberculosis preserves resources and matches the actual transmission route. Option c is incorrect because Droplet precautions are designed for organisms like influenza and pertussis, not for MRSA wound infections. The droplet route is not the main spread for MRSA, so a surgical mask alone is inadequate. Option d is incorrect because Protective isolation is reserved for severely immunocompromised patients to keep pathogens out, not in. The patient with MRSA needs source isolation to prevent spreading the organism to others rather than reverse precautions.

Correct Answer: N95 or higher respirator and standard precautions

Airborne precautions require an N95 or higher respirator and a negative-pressure room. The negative-pressure environment alone does not protect the nurse, who needs respiratory protection sized and fit-tested for personal use during care. Option b is incorrect because A surgical mask does not filter the small airborne particles that carry tuberculosis. Surgical masks are designed for droplet protection, while N95 respirators filter the smaller particles relevant to airborne transmission. Option c is incorrect because A face shield protects the eyes and the face from splashes but does not filter inhaled air. Without an N95 respirator, the nurse remains exposed to airborne particles entering the nose and mouth. Option d is incorrect because Negative pressure prevents air from leaving the room but does not protect anyone inside. Staff entering the room still need an N95 respirator to filter inhaled particles and prevent personal infection.

Correct Answer: Place a surgical mask on the patient

Placing a surgical mask on the patient contains droplets at the source during transport. Source control is the primary protective measure for droplet precautions, and the patient should keep the mask on through the trip. Option a is incorrect because Negative-pressure stretchers are not standard equipment and are unnecessary for droplet precautions. Source control with a surgical mask on the patient is the recommended and practical measure during inter-departmental transport on the unit. Option b is incorrect because An N95 on the transporter is excessive for droplet precautions and may not be available. Surgical masks are designed for droplet protection, and the most important step is masking the patient at the source. Option c is incorrect because Rescheduling the study delays needed care without good clinical reason. Transport with appropriate source control is safe; the nurse should not cancel a study simply because the patient is on droplet precautions.

Correct Answer: Protective environment with restricted exposures

Protective environment isolation reduces the patient's exposure to organisms by limiting visitors with contagious illness, restricting fresh flowers and standing water, and using filtered air. The approach reverses the usual direction of isolation. Option a is incorrect because Contact precautions are designed to protect staff and other patients from a known pathogen on the patient. Neutropenic patients without active infection need protection from outside organisms, not source-control measures around them. Option b is incorrect because Airborne precautions are used when a patient has a known airborne pathogen to keep contained. The neutropenic patient has no airborne pathogen; the goal is to filter incoming air for the patient's safety. Option d is incorrect because Droplet precautions also focus on containing source pathogens and do not match the protective need. The neutropenic patient's risk is from outside organisms, not from droplets the patient may produce during

Correct Answer: Combine droplet and contact precautions together

When an organism spreads by more than one route, the nurse layers precautions to cover all routes. Combined droplet and contact precautions require gown, gloves, and a surgical mask, plus diligent hand hygiene during care. Option b is incorrect because Choosing a single precaution category leaves part of the transmission route unaddressed. Layered precautions protect staff, family, and other patients from each pathway through which the organism can spread. Option c is incorrect because Airborne precautions do not automatically cover droplet and contact transmission routes. Airborne organisms travel by small particles, while droplet and contact pathogens spread differently and require their own targeted measures together. Option d is incorrect because Standard precautions alone are insufficient when a known organism spreads by droplet and contact. Family presence does not change the need for transmission-based precautions; family members also follow the protocol.
