Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?
- A. Losartan
- B. Spironolactone
- C. Metoprolol
- D. Furosemide
Correct Answer: B
Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?
- A. Apply a pressure dressing around the chest tube site.
- B. Administer an oral antihistamine.
- C. Assess for allergies to topical cleaning agents.
- D. Measure the area of swelling and crackling.
Correct Answer: D
Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.
The nurse is caring for a client with chronic renal failure who is receiving dialysis. The client reports muscle cramps and tingling in the hands. Which laboratory result should the nurse monitor to identify the cause of these symptoms?
- A. Sodium
- B. Calcium
- C. Phosphate
- D. Potassium
Correct Answer: B
Rationale: Muscle cramps and tingling in clients with chronic renal failure are often associated with hypocalcemia. Monitoring calcium levels is crucial to identify imbalances and manage symptoms appropriately. Sodium, phosphate, and potassium levels are important in renal failure but are not directly related to the symptoms of muscle cramps and tingling reported by the client.
A male client with heart failure becomes short of breath, anxious, and has pink frothy sputum. What is the first action the nurse should take?
- A. Consult the charge nurse about administering morphine.
- B. Administer the morphine sulfate as prescribed.
- C. Withhold the morphine until the dyspnea resolves.
- D. Review the need for the morphine prescription with the provider.
Correct Answer: B
Rationale: The correct answer is B: Administer the morphine sulfate as prescribed. In this situation, the client is experiencing symptoms of acute pulmonary edema, a complication of heart failure. Morphine is indicated as it helps reduce anxiety and respiratory distress by decreasing preload and afterload. It dilates blood vessels, reducing the workload of the heart and improving oxygenation. The priority is to administer the morphine promptly to alleviate the client's distress and improve oxygenation. Consulting the charge nurse (A) or reviewing the need for the morphine prescription with the provider (D) would cause a delay in providing essential treatment. Withholding the morphine (C) would not be appropriate as it is indicated for this condition.
A woman who is breastfeeding calls her obstetrician's office and reports increased anxiety since the vaginal delivery of her son three weeks ago. She stopped taking her antianxiety medications but is thinking of restarting them. What response should the nurse provide?
- A. Describe the potential transmission of drugs to the infant through breast milk.
- B. Encourage her to utilize stress-relieving alternatives, such as deep breathing.
- C. Explain that anxiety is a common reaction for mothers of 3-week-old infants.
- D. Inform her that some antianxiety medications are safe to take while breastfeeding.
Correct Answer: D
Rationale: The correct answer is D because some antianxiety medications are considered safe during breastfeeding. The nurse should reassure the client and encourage her to discuss options with her healthcare provider to manage anxiety safely while continuing to breastfeed. Choice A is incorrect because it focuses on the transmission of drugs rather than providing guidance on safe medication use. Choice B, while promoting stress-relieving techniques, does not address the potential need for medication. Choice C is incorrect as it minimizes the woman's reported anxiety, which may require professional intervention.
A 66-year-old woman is retiring and needs health insurance. To which agency should the employee health nurse refer her?
- A. Medicaid
- B. Medicare
- C. COBRA
- D. Private insurance
Correct Answer: B
Rationale: The correct answer is B: Medicare. Medicare is the federal health insurance program for individuals aged 65 and older, so it is the most suitable option for the 66-year-old woman retiring. Medicaid (choice A) is a state and federally funded program for low-income individuals and families, not specifically for retirees. COBRA (choice C) allows employees to continue their employer-sponsored health insurance for a limited time after leaving employment. Private insurance (choice D) refers to health insurance plans purchased directly from private insurance companies.
