Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value is most concerning?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 1.5 mg/dl
• C. Serum creatinine of 2.5 mg/dl
• D. White blood cell count of 8,000/mm3

Correct answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

2. A client with cirrhosis is admitted with jaundice and ascites. Which intervention should the nurse implement first?

• A. Administer a diuretic as prescribed.
• B. Administer lactulose as prescribed.
• C. Monitor the client's weight daily.
• D. Assess the client's neurological status.

Correct answer: B

Rationale: Administering lactulose is the first priority in managing a client with cirrhosis to reduce ammonia levels and prevent worsening hepatic encephalopathy. Lactulose helps in decreasing the absorption of ammonia in the intestines and promotes its excretion through the stool. This intervention is crucial in preventing the development or progression of hepatic encephalopathy. Administering a diuretic (Choice A) may be necessary to manage ascites, but it is not the priority over lactulose in this scenario. Monitoring the client's weight (Choice C) is important to assess fluid retention but is not the first intervention required. Assessing the client's neurological status (Choice D) is essential in cirrhosis, but administering lactulose takes precedence to prevent hepatic encephalopathy.

3. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?

• A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
• B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
• C. The additive effect of multiple medications has caused the blood pressure to drop too low.
• D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.

Correct answer: C

Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.

4. 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.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding is most concerning to the nurse?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: 'Use of accessory muscles.' In a client with a history of COPD, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure, necessitating immediate intervention. This finding is concerning as it suggests the client is struggling to breathe adequately. Oxygen saturation of 90% (choice A) is low but may be expected in COPD patients; it requires monitoring and intervention but is not as immediately concerning as the use of accessory muscles. A respiratory rate of 24 breaths per minute (choice B) is within a normal range and, although slightly elevated, may be a typical response to pneumonia. Inspiratory crackles (choice D) can be a common finding in pneumonia and are not as indicative of impending respiratory failure as the use of accessory muscles.
