Nursing Elites

1. A nurse is planning care for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/minute
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate of 14 mL/minute indicates severe kidney dysfunction, necessitating hemodialysis. The other options, BUN of 16 mg/dL, serum magnesium of 1.8 mg/dL, and serum phosphorus of 4.0 mg/dL, are within normal ranges and do not serve as indications for hemodialysis.

2. A nurse is preparing to perform tracheostomy care for a client. Which of the following actions should the nurse take first?

• A. Apply a sterile dressing.
• B. Suction the tracheostomy.
• C. Remove the inner cannula.
• D. Clean the stoma with sterile saline.

Correct answer: B

Rationale: Suctioning the tracheostomy should be performed first to clear the airway of secretions and ensure proper oxygenation before proceeding with other care. This helps maintain a patent airway and prevent complications such as aspiration. Applying a sterile dressing, removing the inner cannula, or cleaning the stoma can follow after ensuring adequate airway clearance through suctioning.

3. A nurse is caring for a client who has a new prescription for metformin. Which of the following findings in the client's medical history should the nurse report to the provider?

• A. History of hypertension
• B. History of polycystic ovary syndrome
• C. History of asthma
• D. History of kidney disease

Correct answer: D

Rationale: The correct answer is D, history of kidney disease. Metformin should be used with caution in clients with kidney disease due to the risk of lactic acidosis, a serious complication. Reporting this finding to the provider is crucial for assessing the appropriateness of continuing metformin therapy. Choices A, B, and C do not contraindicate the use of metformin, so they are not the priority for reporting.

4. A nurse is assessing a client who has a potassium level of 3.0 mEq/L. Which of the following findings should the nurse expect?

• A. Diarrhea
• B. Muscle weakness
• C. Hypertension
• D. Bradycardia

Correct answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.

5. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.
