Question 1 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium in hyperkalemia. A potassium level of 3.8 mEq/L (normal) indicates effectiveness. Ammonia, glucose, and hemoglobin are unaffected.
Question 2 of 5
A client who is experiencing vasomotor symptoms related to menopause receives a new prescription for estrogen replacement. Which client condition should the nurse report to the healthcare provider prior to administering the first dose of the medication?
Correct Answer: B
Rationale: Estrogen increases thromboembolism risk, and a history of pulmonary embolism is a contraindication due to potential recurrence. Colorectal cancer, dyspareunia, and osteoporosis are not absolute contraindications; estrogen may even benefit osteoporosis.
Question 3 of 5
The nurse is assessing a client who was recently diagnosed with Parkinson’s disease and is taking carbidopa-levodopa. The client is concerned that the medication is not working. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: Clarifying the client’s concern about carbidopa-levodopa’s effectiveness guides targeted assessment. Urine color, dyskinesia, or meal timing are secondary until the specific issue is understood.
Question 4 of 5
The nurse is reviewing the laboratory results of a client who reports taking five times the recommended daily allowance of vitamins and minerals in a multivitamin form. Which finding indicates a possible vitamin D overdose? Reference Range: Bilirubin [0.3 to 1 mg/dL (5.1 to 17 μmol/L)] Calcium [9 to 10.5 mg/dL (2.3 to 2.6 mmol/L)] Sodium [136 to 145 mEq/L (136 to 145 mmol/L)] Blood Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]
Correct Answer: B
Rationale: Excessive vitamin D increases calcium absorption, causing hypercalcemia (12 mg/dL). This indicates a possible overdose, risking symptoms like nausea or confusion. Sodium, bilirubin, and glucose levels are unrelated to vitamin D toxicity.
Question 5 of 5
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: B
Rationale: Smoking impairs ulcer healing. Reducing to a pack daily is insufficient; quitting is ideal. Monitoring sexual dysfunction, reporting lethargy, and timing with antacids are appropriate.
