Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. When a patient is taking glucocorticoids and digoxin, which electrolyte should the nurse prioritize monitoring?

• A. Calcium
• B. Magnesium
• C. Sodium
• D. Potassium

Correct answer: D

Rationale: The nurse should primarily monitor potassium levels in a patient taking glucocorticoids and digoxin. Glucocorticoids can lead to potassium loss, potentially increasing the risk of digoxin toxicity. Additionally, glucocorticoids may worsen hypokalemia induced by diuretics like thiazides and loops. While calcium, magnesium, and sodium are important electrolytes to monitor in various clinical situations, they are not the priority in this specific scenario of a patient on glucocorticoids and digoxin.

3. Which parental statement indicates correct understanding of preventive techniques for heat-related illnesses when children exercise?

• A. Wearing dark clothing during exercise is not recommended.
• B. Water is the preferred fluid for fluid replenishment.
• C. During activity, stopping for fluids every 15 to 20 minutes is essential.
• D. Hydration should be maintained throughout the exercise session.

Correct answer: C

Rationale: The correct preventive technique for heat-related illnesses during exercise is to stop for fluids every 15 to 20 minutes to prevent dehydration and maintain hydration levels. This practice helps regulate body temperature and prevent heat-related complications. Choice A is incorrect as wearing light-colored, loose-fitting clothing is recommended to reflect sunlight and allow better air circulation. Choice B is incorrect as while water is important, a sports drink containing electrolytes may be more beneficial for longer exercise sessions. Choice D is incorrect as it does not emphasize the importance of regular fluid intake during exercise to prevent dehydration.

4. A nurse assesses a male patient who has developed gynecomastia while receiving treatment for peptic ulcers. Which medication from the patient’s history should the nurse recognize as a contributing factor?

• A. Amoxicillin (Amoxil)
• B. Cimetidine (Tagamet)
• C. Metronidazole (Flagyl)
• D. Omeprazole (Prilosec)

Correct answer: B

Rationale: Cimetidine binds to androgen receptors, producing receptor blockade, which can cause enlarged breast tissue, reduced libido, and impotence. All these effects reverse when dosing stops. Amoxicillin, metronidazole, and omeprazole are not associated with gynecomastia.

5. An 80-year-old patient with a history of renal insufficiency was recently started on cimetidine. Which assessment finding indicates that the patient may be experiencing an adverse effect of the medication?

• A. Pain with urination
• B. New onset disorientation to time and place
• C. HR changes from a baseline of 70-80bpm to 110-120bpm
• D. #ERROR!

Correct answer: B

Rationale: The correct answer is B: New onset disorientation to time and place. Cimetidine can cause adverse effects on the CNS system, especially in elderly patients with renal or hepatic impairment. This may manifest as confusion, hallucinations, lethargy, restlessness, or seizures. Pain with urination (choice A) is not typically associated with cimetidine use, and HR changes (choice C) are more likely related to other factors. Choice D is not a valid option.
