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? Which blood value indicates to the nurse that the medication is having the desired effect?
Correct Answer: D
Rationale: Calcium acetate is a phosphate binder used in CKD to lower elevated phosphate levels. A decrease in phosphate levels indicates the medication is effectively binding phosphate in the gut, preventing hyperphosphatemia complications.
Question 2 of 5
A female client with mild depression reports to the nurse of recently starting St. John's wort. Which information provided by the client requires further instruction? Which information provided by the client requires further instruction?
Correct Answer: D
Rationale: St. John’s wort induces cytochrome P450 enzymes, reducing the efficacy of hormonal contraceptives. The client’s statement that no additional contraception is needed is incorrect, requiring instruction to use alternative methods to prevent pregnancy.

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? Which action should the nurse take?
Correct Answer: D
Rationale: Insomnia is a common initial side effect of rivastigmine, a cholinesterase inhibitor, which may resolve as the body adjusts. Explaining this to the caregiver manages expectations and encourages continued adherence.
Question 4 of 5
A client receives a prescription for a secondary infusion of IV erythromycin 1 gram in 200 mL dextrose 5% in water (D5W) to be infused in 90 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter the numerical value only. If rounding is required, round to the nearest whole number.) The nurse should program the infusion pump to deliver how many mL/hour?
Correct Answer: 133
Rationale: Volume = 200 mL; time = 90 minutes = 1.5 hours; infusion rate = 200 mL ÷ 1.5 hours = 133.33 mL/hr, rounded to 133 mL/hr.
Question 5 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL.'
