1. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value is most concerning?
- A. Serum glucose of 300 mg/dl
- B. Serum bicarbonate of 18 mEq/L
- C. Serum potassium of 5.5 mEq/L
- D. Serum sodium of 135 mEq/L
Correct answer: C
Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.
2. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be monitored closely?
- A. Serum sodium of 135 mEq/L
- B. Serum potassium of 4.5 mEq/L
- C. Serum creatinine of 1.8 mg/dl
- D. Serum glucose of 200 mg/dl
Correct answer: C
Rationale: In a client with left-sided heart failure, monitoring serum creatinine is crucial to evaluate kidney function and fluid balance. Elevated creatinine levels can indicate impaired kidney function, which is common in heart failure due to decreased cardiac output and renal perfusion. Serum sodium levels (choice A) are important but are more closely associated with fluid balance and heart failure exacerbation. Serum potassium (choice B) is also important to monitor, but it is more closely linked to cardiac arrhythmias rather than kidney function. Serum glucose levels (choice D) are significant but are not the priority for monitoring in left-sided heart failure.
3. The nurse is caring for a client who is postoperative following a thyroidectomy. Which assessment finding is most concerning?
- A. Slight difficulty swallowing
- B. Hoarse voice
- C. Positive Chvostek's sign
- D. Pain at the incision site
Correct answer: C
Rationale: A positive Chvostek's sign is the most concerning assessment finding as it suggests hypocalcemia, which is a potential complication following thyroidectomy. Hypocalcemia can lead to serious complications such as tetany and laryngospasm. Immediate intervention is required to prevent further complications. Choices A, B, and D are common post-thyroidectomy findings and are expected during the immediate postoperative period. Slight difficulty swallowing may be due to postoperative swelling, a hoarse voice may be temporary due to intubation trauma, and pain at the incision site is normal after surgery.
4. A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium level
- B. White blood cell count
- C. Hemoglobin level
- D. Serum calcium level
Correct answer: A
Rationale: The correct answer is A: Serum potassium level. In a client receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increased demand for potassium. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because erythropoietin therapy specifically impacts potassium levels, not white blood cell count, hemoglobin level, or serum calcium level.
5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?
- A. Use of accessory muscles
- B. Oxygen saturation of 94%
- C. Carbon dioxide level of 45 mmHg
- D. Respiratory rate of 20 breaths per minute
Correct answer: C
Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.
