Nursing Elites

1. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

• A. Widening QRS complexes and flat T waves
• B. Tachycardia and elevated blood pressure
• C. Restlessness and anxiety
• D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

2. A confused, older client with Alzheimer's disease becomes incontinent of urine when attempting to find the bathroom. Which action should the nurse implement?

• A. Assist the client to a bedside commode every two hours
• B. Insert an indwelling catheter
• C. Use adult diapers to manage incontinence
• D. Restrict fluids in the evening

Correct answer: A

Rationale: The correct action for the nurse to implement is to assist the client to a bedside commode every two hours. This approach, known as scheduled toileting, is essential in managing incontinence in clients with cognitive impairments like Alzheimer's disease. By providing regular assistance to the client to use the commode, the nurse can help maintain continence and reduce accidents. Inserting an indwelling catheter (Choice B) should be avoided if possible to prevent the risk of urinary tract infections. Using adult diapers (Choice C) should be considered a last resort and not the initial intervention. Restricting fluids in the evening (Choice D) is not appropriate as it may lead to dehydration and other complications.

3. The mother of an adolescent tells the clinic nurse, 'My son has athlete's foot. I have been applying triple antibiotic ointment for two days, but there has been no improvement.' What instruction should the nurse provide?

• A. Antibiotics take two weeks to become effective against fungal infections like athlete's foot.
• B. Continue using the ointment for a full week, even after the symptoms disappear.
• C. Applying too much ointment can reduce its effectiveness. Apply a thin layer to prevent maceration.
• D. Stop using the ointment and encourage complete drying of the feet and wearing clean socks.

Correct answer: D

Rationale: The correct answer is D. Athlete's foot (tinea pedis) is a fungal infection, not a bacterial infection that would respond to antibiotics. The primary management involves keeping the feet well-ventilated, dry after bathing, and wearing clean socks to prevent moisture buildup, which promotes fungal growth. Using an antibiotic ointment like triple antibiotic ointment is not effective for treating athlete's foot. Therefore, the nurse should advise the mother to stop using the antibiotic ointment and focus on promoting proper foot hygiene to manage the fungal infection. Choices A, B, and C are incorrect as they do not address the fungal nature of athlete's foot and the ineffectiveness of antibiotic ointments in its treatment.

4. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push.
• B. Administer insulin as prescribed.
• C. Monitor the client's urine output.
• D. Obtain a blood glucose level.

Correct answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating a blood glucose level of 600 mg/dl in a client who is unresponsive due to hyperglycemia. This intervention is crucial to rapidly raise the client's blood glucose levels and address the emergency situation. Administering insulin (Choice B) would further lower the blood glucose level, worsening the client's condition. Monitoring urine output (Choice C) and obtaining a blood glucose level (Choice D) are important assessments but are secondary to the immediate need to address the high blood glucose levels causing the client's unresponsiveness.

5. A client with a history of myocardial infarction is admitted with chest pain. Which laboratory value should the nurse monitor closely?

• A. White blood cell count
• B. Serum creatinine
• C. Troponin level
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C: Troponin level. Troponin levels should be closely monitored in a client with chest pain and a history of myocardial infarction to assess for ongoing myocardial injury. Troponin is a specific marker for myocardial damage. Monitoring white blood cell count (choice A) is not directly related to myocardial infarction. Serum creatinine (choice B) is more indicative of renal function rather than cardiac status. Hemoglobin level (choice D) is important but does not directly reflect ongoing myocardial injury.
