NR-446 Collaborative Healthcare - Set 5 - Part 3

Correct Answer: Glucose in the urine pulls water along

Glucose that exceeds the renal threshold spills into the urine and drags water with it by osmosis. The resulting osmotic diuresis produces polyuria, and the fluid loss drives the intense thirst of polydipsia. Option b is incorrect because diabetes does not cause the kidney to swell against the bladder. The frequency here comes from a large volume of dilute urine, not from bladder irritation or an obstructed outflow. Option c is incorrect because this client has too little effective insulin, not too much, and sodium retention would reduce urine output rather than increase it. Sodium handling explains neither the polyuria nor the thirst. Option d is incorrect because ketone production belongs to the picture of ketoacidosis and is not what makes a newly diagnosed client thirsty. Thirst follows the water lost through the kidneys during osmotic diuresis.

Correct Answer: Reduced antidiuretic hormone effect with advancing age

With age the renal tubules respond less to antidiuretic hormone rather than the hormone being lacking, so water is reabsorbed poorly. Urine stays dilute and fluid losses mount, raising dehydration risk. Option a is incorrect because gonadotropins drive puberty, maturing the ovaries and testes and stimulating estrogen and testosterone. They actually rise in later life as sex hormone feedback fades, but they do not govern renal water handling. Option b is incorrect because a slowed metabolism in older adults shows itself as cold intolerance and a smaller appetite. Neither of those explains dilute urine or a tendency toward fluid depletion. Option c is incorrect because calcitonin governs serum calcium by lowering it, and it has no role in renal water handling. Choosing it confuses a bone and mineral hormone with a fluid balance hormone.

Correct Answer: Rate of hospital acquired pressure injuries

An outcome measure reports what happened to the client. The hospital acquired pressure injury rate captures the effect of care on patients, which is exactly what outcome measurement is meant to show. Option a is incorrect because class attendance counts what staff did rather than what happened to any client, which keeps it out of the outcome category even though students routinely read education figures as results. Option b is incorrect because equipment on hand belongs to structure, the category covering the setting and its resources. Having mattresses available makes good care possible but says nothing about whether any skin broke down. Option d is incorrect because a repositioning percentage describes what nurses did, placing it firmly in the process category. Compliance figures like this one predict outcomes but are not themselves a measure of client effect.

Correct Answer: A volume variance outside the manager's control

Extra patient days drove the overage while hours per patient day and the hourly rate held to plan. Census is set by admissions, so this portion is not the manager's fault and calls for a flexed budget. Option b is incorrect because the efficiency component isolates hours used per patient day, and that figure matched the budget exactly. Scheduling, sitters and orientation hours would show up there, and none of them moved. Option c is incorrect because price per hour was unchanged. Overtime, agency staff and shift differentials raise the average hourly cost, and that is the only way this component becomes unfavorable. Option d is incorrect because spending more than planned is unfavorable by definition, whatever the reason behind it. The label is correct; what needed explaining was the driver, and the driver here was census.

Correct Answer: Ask the aide for the glucose meter while assessing

A behavior change in a client with diabetes who missed a meal is hypoglycemia until a number proves otherwise. Fetching equipment suits the aide, while the focused assessment stays with the nurse. Option a is incorrect because charting a refusal treats uncooperativeness as a choice rather than a warning sign. Neuroglycopenia makes clients irritable and resistant, and documentation without assessment lets the glucose keep falling. Option c is incorrect because an hour is a long time for a falling glucose, and delegating a repeat set of vital signs does not obtain the value that matters. The nurse needs a glucose reading now. Option d is incorrect because the provider will ask for a glucose value the nurse does not yet have. Communicating with the provider is also a nursing responsibility that should not be handed to an aide.

Correct Answer: Teaching self-management to members with chronic illness

Capitation pays a fixed amount per member per month, so the organization keeps more when members stay well. Teaching, screening and chronic disease management protect that payment by preventing avoidable illness and hospital use. Option a is incorrect because volume drives revenue only under fee-for-service, where the payer carries the risk. Adding procedures under a capitated contract consumes the fixed payment already received and reduces what remains. Option b is incorrect because charge capture matters when each item is billed separately. A per-member payment is not itemized, so recording each supply changes internal cost data rather than the money coming in. Option c is incorrect because a longer stay adds cost without adding payment here. Prolonging admissions is the behavior a per diem arrangement rewards, and it works directly against a prepaid population contract.

Correct Answer: Fewer nurses delay recognition and rescue of complications

Failure to rescue is the mechanism the evidence identifies. Nurses do not prevent every complication; they catch them. Fewer nurses means fewer eyes, later recognition and later treatment, and each added client per nurse raises mortality odds. Option b is incorrect because it overstates what nurses control. Many complications arise from the disease and the treatment regardless of staffing; the difference nursing makes lies in how quickly deterioration is noticed and acted upon. Option c is incorrect because bed closures and diversion are operational responses to a shortage rather than the pathway to death. Restricting admissions may follow poor staffing, but it is not what the mortality studies measured. Option d is incorrect because delayed teaching harms after discharge, through readmission rather than inpatient death. The named finding concerns clients who die following a complication that better staffing would have caught in time.

Correct Answer: Chest pounding and racing pulse have started.

Palpitations and a racing pulse point to over-replacement, which can push a client into angina or a dysrhythmia. That report needs the provider, while the other changes show the dose is working. Option a is incorrect because relief of constipation is one of the first signs replacement is restoring normal gut motility. It is a welcome change and calls for praise rather than a call to the provider. Option b is incorrect because dry skin is a hypothyroid feature that softens as hormone levels normalize. Improvement here confirms the therapy is reaching the tissues and needs no intervention at all. Option d is incorrect because gradually returning energy matches the expected timeline, since symptom relief takes three to four weeks. Reporting it would waste the provider's attention on evidence that treatment is succeeding.

Correct Answer: Around ten thirty in the morning

Regular insulin has an onset of thirty to sixty minutes and peaks about two and a half hours after the dose, which places the greatest hypoglycemia risk near ten thirty for an eight o'clock injection. Option a is incorrect because regular insulin has not even begun to act fifteen minutes after injection. That onset belongs to the rapid-acting analogues such as lispro and aspart, which work far sooner. Option b is incorrect because by late afternoon the dose is on the tail of its six to ten hour duration. Activity is waning there, so risk is lower than at the peak. Option c is incorrect because a morning dose of regular insulin has largely worn off by evening. Evening risk would belong to an intermediate-acting insulin given in the morning, whose peak falls many hours later.

Correct Answer: The FOCUS model of process improvement

FOCUS names five steps: find a process to improve, organize a team that knows it, clarify current practice, understand the causes of variation, and select the improvement. It is usually paired with Plan-Do-Study-Act cycles. Option a is incorrect because value stream mapping charts the whole client journey and marks which minutes add value and which do not. The council's steps describe assembling a team and studying variation instead. Option c is incorrect because its five phases are define, measure, analyze, improve, and control, and the control phase exists to hold statistical gains. None of those phase names matches the sequence the council used. Option d is incorrect because that method maps a process not yet in use, lists every way each step could fail, and scores the risk before go-live. The council is improving a process already operating.
