Nursing Elites

1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

• A. Arterial blood gas (ABG) values
• B. Serum potassium level
• C. Serum sodium level
• D. Serum magnesium level

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.

2. The nurse is caring for a client with chronic kidney disease (CKD). Which laboratory value should be reported to the healthcare provider immediately?

• A. Serum creatinine of 2.0 mg/dl
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.5 mEq/L
• D. Blood glucose of 150 mg/dl

Correct answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

3. A client with a tracheostomy has thick, tenacious secretions. Which intervention should the nurse implement first?

• A. Perform deep suctioning every 2 to 4 hours.
• B. Encourage the client to drink plenty of fluids.
• C. Increase humidity in the client's room.
• D. Administer a mucolytic agent.

Correct answer: C

Rationale: Increasing humidity in the client's room can help liquefy thick secretions and facilitate easier airway clearance in a client with a tracheostomy. This intervention should be implemented first as it is non-invasive and can often effectively address the issue of thick secretions. Performing deep suctioning (Choice A) should not be the first intervention as it is more invasive and should be done based on assessment findings. Encouraging the client to drink plenty of fluids (Choice B) is beneficial but may not provide immediate relief for thick secretions. Administering a mucolytic agent (Choice D) requires a healthcare provider's prescription and should be based on assessment data and the client's condition.

4. 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.

5. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum potassium of 5.5 mEq/L
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.0 mEq/L
• D. Blood glucose of 200 mg/dl

Correct answer: C

Rationale: The correct answer is C: Potassium of 6.0 mEq/L. A potassium level of 6.0 mEq/L is dangerously high in a client with CKD, and it should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Choices A, B, and D are not the most critical values to report before hemodialysis. While a serum potassium level of 5.5 mEq/L is slightly elevated, it is not as urgent as a level of 6.0 mEq/L in this context. Hemoglobin of 10 g/dl and blood glucose of 200 mg/dl are important parameters to monitor but are not as immediately concerning before hemodialysis compared to a high potassium level.
