Question 1 of 5
A client receives a prescription for penicillin 1.2 million units IM. The available vial is labeled, '600,000 units/2 mL.' How many mL should the nurse administer? (Enter numeric value only.)
Correct Answer: 4
Rationale:
To calculate: (1,200,000 units prescribed) ÷ (600,000 units/2 mL) = 1,200,000 × 2 ÷ 600,000 = 4 mL. The nurse should administer 4 mL to deliver the prescribed 1.2 million units.
Question 2 of 5
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?
Correct Answer: B
Rationale: Adalimumab, an immunosuppressant, increases infection risk. Avoiding crowds and sick individuals minimizes exposure, protecting the client’s compromised immune system. Eye exams, chest x-rays, or vaccinations are not specifically required for adalimumab initiation.
Question 3 of 5
Which action should the nurse implement to assess the effectiveness of amlodipine?
Correct Answer: B
Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure to manage hypertension. Measuring blood pressure directly assesses its effectiveness. Electrolytes, intake/output, or calcium levels are not primary indicators of amlodipine’s therapeutic effect.
Question 4 of 5
The nurse is educating a client about acetaminophen. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: C
Rationale: Taking additional acetaminophen doses risks overdose and liver damage. Clients should follow prescribed dosing and consult providers if pain persists. Avoiding alcohol, reporting urine color changes, and stopping for rashes are appropriate.
