Which electrolyte imbalance would be the nurse's priority concern in the burn client?
- A. Hypernatremia
- B. Hyperkalemia
- C. Hypoalbuminemia
- D. Hypermagnesemia
Correct Answer: B
Rationale: The correct answer is hyperkalemia. In a burn client, the nurse's priority concern is hyperkalemia due to cell lysis, which releases potassium into the bloodstream. This can lead to dangerous levels of potassium in the blood. Hypernatremia (Choice A) is less likely in burn clients. Hypoalbuminemia (Choice C) can occur but is not the priority in the immediate management of a burn client. Hypermagnesemia (Choice D) is not typically associated with burn injuries.

Which medication should the nurse withhold if the client's blood pressure is 88/50?
- A. Rosuvastatin (Crestor)
- B. Enalapril (Vasotec)
- C. Digoxin (Lanoxin)
- D. Clopidogrel (Plavix)
Correct Answer: B
Rationale: Enalapril (Vasotec) is the correct answer. It is an angiotensin-converting enzyme (ACE) inhibitor that can further lower blood pressure. Given that the client's blood pressure is already low at 88/50, administering Enalapril could exacerbate hypotension and compromise perfusion to vital organs. Rosuvastatin (Crestor), Digoxin (Lanoxin), and Clopidogrel (Plavix) are not contraindicated in the context of low blood pressure and may be administered safely.
The client is admitted to the hospital following a motor vehicle accident and has sustained a closed chest wound. Which assessment finding is consistent with a flail chest?
- A. Biot's respirations
- B. Sucking sounds during respirations
- C. Paradoxical chest wall movement
- D. Hypotension and bradycardia
Correct Answer: C
Rationale: The correct assessment finding consistent with a flail chest is paradoxical chest wall movement. This occurs when a segment of the chest wall moves in the opposite direction to the rest of the chest during respiration. Biot's respirations (Choice A) are a pattern of breathing characterized by groups of quick, shallow inspirations followed by regular or irregular periods of apnea. Sucking sounds during respirations (Choice B) may indicate air entering or leaving the chest cavity through a wound. Hypotension and bradycardia (Choice D) may be present due to other factors such as shock, but they are not specific to a flail chest.
What is the most common cause of acute renal failure?
- A. Shock
- B. Nephrotoxic drugs
- C. Enlarged prostate
- D. Diabetes
Correct Answer: A
Rationale: The correct answer is 'Shock.' Acute renal failure is commonly caused by inadequate blood flow to the kidneys, which can occur in cases of shock. This leads to decreased kidney function and potential kidney damage. While nephrotoxic drugs can also cause acute renal failure, shock is the primary and most common cause. An enlarged prostate may lead to obstructive uropathy but is not the most prevalent cause of acute renal failure. Diabetes is typically associated with chronic kidney disease rather than acute renal failure.
The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?
- A. Facial flushing
- B. A complaint of chest heaviness
- C. Heart rate increase of 10 beats/min
- D. Systolic blood pressure increase of 10 mm Hg
Correct Answer: B
Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.
The client is taking Antabuse and should avoid eating foods that may trigger a disulfiram reaction. The nurse should instruct the client to avoid:
- A. Peanuts, dates, raisins
- B. Figs, chocolate, eggplant
- C. Pickles, salad with vinaigrette dressing, beef
- D. Milk, cottage cheese, ice cream
Correct Answer: C
Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.
