1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?

Correct answer: A

Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.

2. A client with a history of hypertension is admitted with a blood pressure of 200/110 mmHg. Which intervention should the nurse implement first?

Correct answer: D

Rationale: The correct answer is to obtain an arterial blood gas (ABG) sample. In a client with severe hypertension, it is essential to assess for metabolic or respiratory acidosis which can be done through an ABG sample. Administering antihypertensive medication without assessing the acid-base status of the client can lead to potential complications. Monitoring urine output and administering oxygen therapy are important interventions but are not the priority in this situation where the focus should be on assessing acidosis.

3. A client with newly diagnosed hypertension is being taught about lifestyle modifications by a nurse. Which client statement indicates a need for further teaching?

Correct answer: D

Rationale: The correct answer is D. Limiting caffeine intake is a positive lifestyle modification for managing hypertension. The statement indicates that the client understands the importance of reducing caffeine intake. Choices A, B, and C all reflect appropriate lifestyle modifications for managing hypertension, indicating good understanding by the client.

4. A client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). Which laboratory value should the nurse monitor closely?

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen), monitoring serum potassium levels closely is crucial. Epoetin alfa stimulates red blood cell production, which can lead to an increase in potassium levels. Hyperkalemia is a potential risk in these clients. Monitoring hemoglobin levels (choice A) is important in assessing the effectiveness of epoetin alfa therapy, but it is not the laboratory value that poses an immediate risk related to the medication. White blood cell count (choice B) and serum creatinine (choice D) are not directly affected by epoetin alfa therapy and are not the priority laboratory values to monitor in this case.

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?

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.
