1. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium level
- B. Hemoglobin level
- C. White blood cell count
- D. Serum calcium level
Correct answer: A
Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.
2. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?
- A. Serum potassium
- B. Hemoglobin
- C. Serum sodium
- D. White blood cell count
Correct answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.
3. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?
- A. Serum sodium of 135 mEq/L
- B. Serum potassium of 4.0 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum glucose of 300 mg/dL
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.
4. When organizing home visits for the day, which older client should the home health nurse plan to visit first?
- A. A woman who takes naproxen (Naprosyn) and reports a recent onset of dark, tarry stools.
- B. A man who receives weekly injections of epoetin (Procrit) for a low serum iron level.
- C. A man with emphysema who smokes and is complaining of white patches in his mouth.
- D. A frail woman with heart failure who reported a 2-pound weight gain in the last week.
Correct answer: A
Rationale: The correct answer is A. Dark, tarry stools may indicate gastrointestinal bleeding, a potentially life-threatening condition that requires immediate attention. Visiting this client first is crucial for prompt assessment and intervention. Choices B, C, and D do not present immediate life-threatening conditions that require urgent attention compared to the potential emergency indicated by dark, tarry stools.
5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning to the nurse?
- A. Barrel-shaped chest
- B. Use of accessory muscles
- C. Oxygen saturation of 85%
- D. Respiratory rate of 28 breaths per minute
Correct answer: C
Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.
