Nursing Elites

1. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

• A. Ask family members to speak quietly to keep the client calm.
• B. Assess urine color, amount, and specific gravity each day.
• C. Encourage the client to drink at least 1 liter of fluids each shift.
• D. Dangle the client on the bedside before ambulating.

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.

2. . A 73-year-old man comes into the emergency department (ED) by ambulance after slipping on a small carpet in his home. The patient fell on his hip with a resultant fracture. He is alert and oriented; his pupils are equal and reactive to light and accommodation. His heart rate is elevated, he is anxious and thirsty, a Foley catheter is placed, and 40 mL of urine is present. What is the nurses most likely explanation for the low urine output?

• A. The man urinated prior to his arrival to the ED and will probably not need to have the Foley catheter kept in place.
• B. The man likely has a traumatic brain injury, lacks antidiuretic hormone (ADH), and needs vasopressin.
• C. The man is experiencing symptoms of heart failure and is releasing atrial natriuretic peptide that results in decreased urine output.
• D. The man is having a sympathetic reaction, which has stimulated the reninangiotensinaldosterone system that results in diminished urine output.

Correct answer: D

3. What percentage of body water can be as high as in a newborn?

• A. 80%.
• B. 70%.
• C. 60%.
• D. 90%.

Correct answer: A

Rationale: The correct answer is A: 80%. Newborns can have a body water content as high as 80% due to their higher total body water compared to adults. Choice B (70%) is incorrect because newborns typically have a higher body water percentage. Choice C (60%) is also incorrect as it underestimates the body water content in newborns. Choice D (90%) is incorrect as it overestimates the body water percentage in newborns.

4. Retention of electrolytes (especially sodium) in the interstitial fluid can result from:

• A. decreased aldosterone secretion.
• B. increased ADH secretion.
• C. increased aldosterone secretion.
• D. decreased ADH secretion.

Correct answer: C

Rationale: The correct answer is C: increased aldosterone secretion. Aldosterone, a hormone produced by the adrenal glands, increases sodium reabsorption in the kidneys, leading to retention of sodium and water in the interstitial fluid. Increased aldosterone secretion enhances the reabsorption of sodium, thereby increasing its retention. Choice A is incorrect because decreased aldosterone secretion would lead to less sodium reabsorption and increased excretion. Choice B is incorrect because increased ADH secretion primarily affects water reabsorption rather than sodium. Choice D is incorrect because decreased ADH secretion would lead to increased water excretion but not necessarily affect sodium retention.

5. A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?

• A. A 34-year-old on NPO status who is receiving intravenous D5W
• B. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic
• C. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin)
• D. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)

Correct answer: A

Rationale: The correct answer is the 34-year-old on NPO status receiving intravenous D5W because D5W is a hypotonic solution that can dilute the blood's sodium levels, leading to hyponatremia. Patients on NPO status rely solely on intravenous fluids for hydration, making them more susceptible to electrolyte imbalances. Choices B, C, and D are less likely to cause hyponatremia. Choice B, the 50-year-old with an infection on a sulfonamide antibiotic, is at risk for allergic reactions or renal issues. Choice C, the 67-year-old taking ibuprofen, is at risk for gastrointestinal bleeding or kidney problems. Choice D, the 73-year-old on digoxin with tachycardia, is more likely to experience digoxin toxicity, affecting the heart's rhythm.
