1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value should be monitored closely?

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. In COPD, especially when the client is receiving diuretics or corticosteroids, monitoring serum potassium levels is crucial. These medications can lead to potassium loss, potentially causing hypokalemia. Arterial blood gas (choice A) values are important in assessing respiratory status but are not the primary concern related to medication side effects. Serum sodium (choice C) and magnesium (choice D) levels are also important, but in the context of COPD exacerbation and medication effects, potassium monitoring takes precedence.

2. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which clinical finding requires immediate intervention?

Correct answer: A

Rationale: The correct answer is A, 'Increased fatigue.' In a client with CKD receiving erythropoietin therapy, increased fatigue can be a sign of polycythemia, a condition characterized by an elevated red blood cell count. This can lead to increased blood viscosity and raise the risk of thromboembolic events, necessitating immediate intervention. Elevated blood pressure (choice B) is a common concern in CKD but does not require immediate intervention in this context. Headache (choice C) may be related to elevated blood pressure but is not the most critical finding requiring immediate attention. Elevated hemoglobin (choice D) is an expected outcome of erythropoietin therapy and does not require immediate intervention unless excessively high.

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

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.

4. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

5. A male client with rheumatoid arthritis is scheduled for a procedure in the morning. The procedure cannot be completed because of early morning stiffness. Which intervention should the nurse implement?

Correct answer: A

Rationale: A warm shower can help reduce morning stiffness, making the procedure more comfortable for the client. This intervention promotes comfort and mobility, addressing the immediate issue of stiffness. Providing a warm blanket (choice B) may offer some comfort but will not address the stiffness as effectively as a warm shower. Delaying the procedure (choice C) may inconvenience the client and not address the underlying stiffness issue. Encouraging range-of-motion exercises (choice D) is important for long-term management but may not provide immediate relief from the stiffness that is hindering the procedure.
