ATI N303 Pharmacology Exam Questions
Extract:
Question 1 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 2 of 5
A nurse is caring for a client who requires a medication that is packaged in a single dose glass ampule. Which of the following techniques should the nurse use when opening the glass ampule?
Correct Answer: C
Rationale: Tapping the top and breaking the ampule away from the body with gauze prevents glass shards from contaminating the medication and ensures safety.
Question 3 of 5
A nurse on a medical unit is planning care for an older adult client who takes several medications. Which of the following prescribed medications places the client at risk for orthostatic hypotension? (Select all that apply.)
Correct Answer: A,B,C
Rationale: Duloxetine can cause blood pressure fluctuations due to its effect on norepinephrine. Furosemide reduces blood volume, increasing the risk of orthostatic hypotension. Telmisartan causes vasodilation, which can lower blood pressure and contribute to orthostatic hypotension.
Question 4 of 5
A nurse is preparing to administer dextrose 5% in water (DW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate: 150 mL × 10 gtt/mL ÷ 180 min = 8.33 gtt/min, rounded to 8 gtt/min, ensuring accurate infusion rate.
Question 5 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.
