Question 1 of 5
A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
Correct Answer: C
Rationale: Standard heparin (IV) and low molecular weight heparin (subcutaneous) are not interchangeable. Requesting standard heparin ensures the correct medication and route, preventing errors.
Question 2 of 5
The nurse is providing medication teaching to a client with bipolar disorder who receives a prescription for lithium carbonate. Which instruction should the nurse emphasize with the client?
Correct Answer: B
Rationale: Adequate fluid intake (1,500-3,000 mL/day) prevents dehydration, which can elevate lithium levels and risk toxicity. Food intake, weight reporting, or fliers are less critical to lithium safety.
Question 3 of 5
Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Correct Answer: D
Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after to prevent hypoglycemia. Synchronizing meal timing is critical. Glucose sources, monitoring, and hypoglycemia checks are secondary.
Question 4 of 5
The nurse administers naloxone to a client with opioid-induced respiratory depression. One hour later, nursing assessment reveals that the client has a respiratory rate of 4 breaths/minute, oxygen saturation of 75%, and is unable to be aroused. Which action should the nurse implement?
Correct Answer: B
Rationale: Persistent respiratory depression (4 breaths/min, 75% saturation) indicates ongoing opioid toxicity. Naloxone’s short half-life may require a second dose to reverse opioid effects. Chest tubes, GCS, or CPR do not address the opioid-related cause.
Question 5 of 5
A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Correct Answer: B
Rationale: Erythromycin may reduce oral contraceptive efficacy. Additional contraception (e.g., condoms) prevents pregnancy. Stopping contraceptives, spacing doses, or avoiding sunlight are incorrect.
