Nursing Elites

1. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

• A. Serum potassium of 4.0 mEq/L
• B. Blood glucose of 200 mg/dl
• C. Serum creatinine of 1.5 mg/dl
• D. Serum potassium of 3.2 mEq/L

Correct answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.

2. A nurse is preparing to insert a nasogastric tube (NGT) in a client. Which action should the nurse take first?

• A. Assess the client's history for nasal trauma or surgery
• B. Ask the client to cough and deep breathe.
• C. Measure the length of the tube to be inserted.
• D. Explain the procedure to the client and obtain consent.

Correct answer: D

Rationale: The correct first action for the nurse to take when preparing to insert a nasogastric tube (NGT) in a client is to explain the procedure to the client and obtain consent. It is crucial to ensure that the client is informed about the procedure, understands it, and consents to it before proceeding. Assessing the client's history for nasal trauma or surgery (Choice A) is important but can be done after obtaining consent. Asking the client to cough and deep breathe (Choice B) is not directly related to the initial step of preparing for NGT insertion. Measuring the length of the tube to be inserted (Choice C) is a necessary step but should come after explaining the procedure and obtaining consent.

3. A male client with impaired renal function who takes ibuprofen daily for chronic arthritis is showing signs of gastrointestinal (GI) bleeding. After administering IV fluids and a blood transfusion, his blood pressure is 100/70 mm Hg, and his renal output is 20 ml/hour. Which intervention should the nurse include in his care plan?

• A. Maintain the client NPO during the diuresis phase.
• B. Evaluate daily serial renal laboratory studies for progressive elevations.
• C. Observe the urine character for sedimentation and cloudy appearance.
• D. Monitor for the onset of polyuria greater than 150 ml/hour.

Correct answer: B

Rationale: In this scenario, the correct intervention for the nurse to include in the care plan is to evaluate daily serial renal laboratory studies for progressive elevations. This is crucial in monitoring renal function and detecting any worsening renal impairment. Option A is not directly related to managing renal function in this case. Option C focuses more on urinary characteristics rather than renal function monitoring. Option D addresses polyuria, which is an excessive urine output, but it does not specifically address the need for evaluating renal laboratory studies for progressive elevations.

4. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

5. The nurse is preparing to administer an IV dose of ciprofloxacin to a client with a urinary tract infection. Which client data requires the most immediate intervention by the nurse?

• A. Serum creatinine of 4.5 mg/dL (398 μmol/L SI)
• B. Temperature of 101.3°F
• C. Blood pressure of 140/90 mmHg
• D. Heart rate of 88 bpm

Correct answer: A

Rationale: A serum creatinine level of 4.5 mg/dL indicates severe renal impairment, which requires immediate attention before administering ciprofloxacin. Elevated serum creatinine levels suggest decreased kidney function, and giving ciprofloxacin can further harm the kidneys. Monitoring and addressing renal function are crucial to prevent worsening of renal impairment and potential drug toxicity. The temperature, blood pressure, and heart rate are important parameters to assess, but in this scenario, the priority is to address the severe renal impairment before proceeding with ciprofloxacin administration.
