Question 1 of 5
A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Correct Answer: B
Rationale: Calcium acetate lowers phosphate levels in CKD by binding dietary phosphate. A decreased phosphate level indicates effectiveness. pH, potassium, and calcium are not primary targets.
Question 2 of 5
The nurse is administering SUBQ enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?
Correct Answer: A
Rationale: A platelet count of 100,000/mm3 indicates thrombocytopenia, increasing bleeding risk with enoxaparin, requiring immediate action. Creatinine, BUN, and hematocrit are within normal ranges.
Question 3 of 5
A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client?
Correct Answer: D
Rationale: Isotretinoin is highly teratogenic, requiring discontinuation at least one month before conception to prevent birth defects. Breastfeeding, vitamin A, and liver monitoring are secondary concerns.
Question 4 of 5
During a home visit, the nurse assesses a client with Alzheimer's disease who recently started a new prescription for rivastigmine. The caregiver reports that the client seems to be thinking more clearly but is not sleeping well at night. Which action should the nurse take?
Correct Answer: B
Rationale: Insomnia is a common, often temporary side effect of rivastigmine. Explaining this reassures the caregiver. Rivastigmine is for cognition, not sleep, and withholding or increasing the dose is inappropriate without provider guidance.
