A client being discharged with a prescription for the bronchodilator theophylline is instructed to take three doses of the medication each day. Since timed-release capsules are not available, which dosing schedule should the nurse advise the client to follow?
- A. 9 a.m., 1 p.m., and 5 p.m.
- B. 8 a.m., 4 p.m., and midnight.
- C. Before breakfast, before lunch, and before dinner.
- D. With breakfast, with lunch, and with dinner.
Correct Answer: B
Rationale: Theophylline should be administered on a regular around-the-clock schedule to provide the best bronchodilating effect and reduce the potential for adverse effects. The correct dosing schedule of 8 a.m., 4 p.m., and midnight ensures that the client receives consistent dosing throughout the day. Other options do not provide the necessary around-the-clock coverage. It's important to note that food may affect the absorption of the medication, which is why the dosing schedule should not be tied to meal times.

When assessing a client with wrist restraints, the nurse observes that the fingers on the right hand are blue. What action should the nurse implement first?
- A. Loosen the right wrist restraint.
- B. Apply a pulse oximeter to the right hand.
- C. Compare hand color bilaterally.
- D. Palpate the right radial pulse.
Correct Answer: A
Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.
When turning an immobile bedridden client without assistance, which action best ensures client safety?
- A. Securely grasp the client's arm and leg.
- B. Put bed rails up on the side of bed opposite from the nurse.
- C. Correctly position and use a turn sheet.
- D. Lower the head of the client's bed slowly.
Correct Answer: B
Rationale: The correct answer is to put bed rails up on the side of the bed opposite from the nurse. This action is essential to prevent the client from falling out of bed during the turning process. Since the nurse can only stand on one side of the bed, having the bed rails up on the opposite side provides an additional safety measure. Securing the client's arm and leg or lowering the head of the bed would not prevent the client from falling and may pose a risk of injury. Using a turn sheet correctly can be helpful, but ensuring the bed rails are up is a more direct safety measure in this situation.
When assessing a male client, the nurse finds that he is fatigued and experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct Answer: D
Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client's laboratory values for potassium levels will help confirm the presence of hypokalemia.

A client is receiving total parenteral nutrition (TPN). Which assessment finding is most concerning to the nurse?
- A. Blood glucose level of 150 mg/dL.
- B. Blood pressure of 110/70 mm Hg.
- C. Serum albumin level of 3.5 g/dL.
- D. The client's temperature is 100.4°F (38°C).
Correct Answer: D
Rationale: A temperature of 100.4°F (38°C) (D) is the most concerning finding for a client receiving total parenteral nutrition (TPN) as it may indicate an infection, which poses a significant risk. Monitoring blood glucose level (A), blood pressure (B), and serum albumin (C) are also important, but an elevated temperature suggests a potential serious complication that requires immediate attention.
