Question 1 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg subcutaneously twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL'. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Calculate: (80 mg ÷ 60 mg) × 0.6 mL = 0.8 mL. The nurse should administer 0.8 mL to deliver 80 mg of enoxaparin.
Question 2 of 5
A client with bipolar disorder admitted with severe depression and suicidal ideation receives a prescription for lithium carbonate. Which instruction should the nurse provide to the client?
Correct Answer: A
Rationale: NSAIDs increase lithium levels, risking toxicity (e.g., tremors, confusion). Eliminating NSAIDs is critical. Glucose, dental notifications, and iodine foods are unrelated to lithium safety.
Question 3 of 5
The nurse is teaching a client with type 1 diabetes mellitus (DM) about the onset, peak, and duration of a new prescription for glargine insulin. If the insulin is administered at 0800, when is the client most likely to experience hypoglycemia?
Correct Answer: B
Rationale: Glargine insulin has no pronounced peak, providing steady coverage for 24 hours, minimizing hypoglycemia risk at specific times. Midmorning, midafternoon, or midnight are not tied to glargine’s profile.
Question 4 of 5
A client with bipolar disorder admitted with severe depression and suicidal ideation receives a prescription for lithium carbonate. Which instruction should the nurse provide to the client?
Correct Answer: A
Rationale: NSAIDs increase lithium levels, risking toxicity (e.g., tremors, confusion). Eliminating NSAIDs is critical. Glucose, dental notifications, and iodine foods are unrelated to lithium safety.
Question 5 of 5
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
Correct Answer: A
Rationale: Zolpidem, a sedative-hypnotic, treats insomnia. Sleeping soundly indicates effectiveness. Incontinence, concentration, and outbursts are unrelated to zolpidem’s action.
