ATI Pharmacology Exam 2 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: C
Rationale: An INR of 5.2 indicates excessive anticoagulation. Vitamin K reverses warfarin's effects by restoring clotting factor synthesis, unlike atropine, epinephrine, or protamine (heparin antidote).
Question 2 of 5
A nurse is caring for a client who has a central venous catheter and reports hearing a gurgling sound on the side of the catheter insertion. Which of the following complications should the nurse suspect?
Correct Answer: C
Rationale: A gurgling sound suggests air entry from catheter dislodgment, a serious issue requiring immediate attention, unlike occlusion, migration, or rupture.
Question 3 of 5
A nurse is caring for a client who is receiving a continuous IV infusion of heparin. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Checking aPTT every 4 hours monitors heparin's anticoagulant effect, ensuring therapeutic levels, unlike specific tubing, excessive bolus, or vitamin K.
Question 4 of 5
A nurse is reviewing the medical record of a client who has hypertension and a new prescription for metoprolol. Which of the following findings should the nurse investigate further?
Correct Answer: C
Rationale: Tadalafil with metoprolol risks hypotension, requiring investigation, unlike heart failure, pneumonia, or diabetes, which are compatible.
Question 5 of 5
A nurse is providing teaching to a client who has hypertension and a new prescription for captopril. Which of the following instructions should the nurse provide?
Correct Answer: B
Rationale: Captopril can cause hyperkalemia; salt substitutes with potassium increase this risk, unlike weight gain, pulse counting, or food intake.
