Nursing Elites

1. A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

2. A client with a history of hypertension is admitted with shortness of breath and chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Pulmonary function tests (PFTs)
• D. Arterial blood gases (ABGs)

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia in a client presenting with shortness of breath and chest pain. This test helps in evaluating the electrical activity of the heart and can identify signs of myocardial infarction or other cardiac issues. Choice B, Chest X-ray, may be ordered after the ECG to assess for pulmonary conditions like pneumonia or effusions. Choice C, Pulmonary function tests (PFTs), are used to evaluate lung function and are not the primary diagnostic tests for a client with symptoms of cardiac origin. Choice D, Arterial blood gases (ABGs), may provide information about oxygenation but are not the initial test indicated for a client with suspected cardiac issues.

3. The charge nurse of the critical care unit informed at the beginning of the shift that a less than optimal number of registered nurses would be working that shift. In planning assignments, which client should receive the most care hours by a registered nurse?

• A. A 34-year-old admitted today after an emergency appendectomy who has a peripheral intravenous catheter and a Foley catheter.
• B. A 48-year-old marathon runner with a central venous catheter experiencing nausea and vomiting due to electrolyte disturbance following a race.
• C. A 63-year-old chain smoker with chronic bronchitis receiving oxygen via nasal cannula and a saline-locked peripheral intravenous catheter.
• D. An 82-year-old client with Alzheimer's disease and a newly fractured femur with a Foley catheter and soft wrist restraints applied.

Correct answer: D

Rationale: The 82-year-old client with Alzheimer's disease and a newly fractured femur should receive the most care hours by a registered nurse because they are at the highest risk for injury and complications. The client's age, diagnosis of Alzheimer's disease, and the presence of a newly fractured femur along with the Foley catheter and wrist restraints indicate a need for close monitoring and care. Choice A is less critical as the client is stable post-appendectomy. Choice B, though experiencing symptoms, is not at the same level of risk as the client in Choice D. Choice C, while requiring oxygen support, does not have the same level of acuity and complexity as the client in Choice D.

4. A male client reports the onset of numbness and tingling in his fingers and around his mouth. Which lab test is important for the nurse to review before contacting the healthcare provider?

• A. Capillary glucose
• B. Urine specific gravity
• C. Serum calcium
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.

5. A client with atrial fibrillation is receiving digoxin (Lanoxin) and warfarin (Coumadin). Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Heart rate of 58 beats per minute
• B. Presence of a new murmur
• C. INR of 2.5
• D. Blood pressure of 110/70 mmHg

Correct answer: B

Rationale: The correct answer is B. The presence of a new murmur in a client with atrial fibrillation may indicate a valvular problem or other complications, requiring immediate reporting. A heart rate of 58 beats per minute is within the normal range for some individuals with atrial fibrillation, so it is not an immediate concern. An INR of 2.5 is within the therapeutic range for a client on warfarin, indicating appropriate anticoagulation. A blood pressure of 110/70 mmHg is also within the normal range and does not pose an immediate threat to the client's health.
