ATI N303 Pharmacology Exam Questions
Extract:
Question 1 of 5
A nurse is teaching a class about routes of medication administration. The nurse should include that which of the following routes has the fastest rate of absorption?
Correct Answer: C
Rationale: Intravenous administration delivers medication directly into the bloodstream, ensuring immediate absorption and the fastest onset of action.
Question 2 of 5
A nurse is preparing to administer a medication to a client who states, 'That looks different from the pill I usually take.' Which of the following responses should the nurse make?
Correct Answer: B
Rationale: Asking the client to describe the pill verifies its identity, ensuring the correct medication is administered and addressing the client's concern.
Question 3 of 5
A nurse is caring for a client who is on warfarin therapy for atrial fibrillation. The client's INR is 5.2. Which of the following medications should the nurse prepare to administer?
Correct Answer: D
Rationale: Vitamin K reverses warfarin's anticoagulant effects by promoting clotting factor synthesis, reducing the high INR of 5.2, which indicates an increased bleeding risk.
Question 4 of 5
A nurse is caring for a client who has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?
Correct Answer: C
Rationale: Crushing enteric-coated aspirin disrupts its protective coating, causing immediate release in the stomach, which can lead to irritation or reduced efficacy.
Question 5 of 5
A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate: 2 mg ÷ 10 mg/mL = 0.2 mL. Administering 0.2 mL ensures the correct dose of morphine sulfate is given.
