Nursing Elites

1. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Blood urea nitrogen (BUN)
• C. Serum creatinine
• D. Serum glucose

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

2. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?

• A. Serum potassium of 3.0 mEq/L
• B. Serum glucose of 200 mg/dl
• C. Serum pH of 7.30
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.

3. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

4. An adult male who fell from a roof and fractured his left femur is admitted for surgical stabilization after having a soft cast applied in the emergency department. Which assessment finding warrants immediate intervention by the nurse?

• A. Weak palpable distal pulses
• B. Pain at the fracture site
• C. Mild swelling of the leg
• D. Bruising around the fracture site

Correct answer: A

Rationale: In a patient with a fractured femur, weak palpable distal pulses can indicate compromised circulation to the lower extremity. This finding suggests a potential vascular compromise that requires immediate intervention to prevent further complications like compartment syndrome or ischemia. Pain at the fracture site, mild swelling of the leg, and bruising around the fracture site are expected following such an injury and surgical stabilization, and while they should be monitored, they do not require immediate intervention like addressing compromised circulation.

5. When assessing a client with left-sided heart failure, which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Monitor the client's urine output.
• C. Administer a loop diuretic as prescribed.
• D. Administer morphine as prescribed.

Correct answer: A

Rationale: Administering oxygen therapy is the initial intervention for a client with left-sided heart failure. This action is crucial in improving oxygen levels and reducing pulmonary congestion. Monitoring urine output is important for assessing renal function in heart failure, but it is not the priority over ensuring adequate oxygenation. Administering loop diuretics helps manage fluid overload but should come after addressing oxygen needs. Morphine may be indicated for pain or anxiety in some cases, but it is not the primary intervention for left-sided heart failure.
