ATI Nurs 180 Pharmacology Exam Questions
Extract:
Question 1 of 5
A client presents to the healthcare setting and ordered verapamil (Calan) to treat his hypertension. Which assessment finding by the nurse would determine if the medication should be held?
Correct Answer: D
Rationale: Verapamil may be held if the pulse is significantly low (<60 bpm) due to its heart rate-lowering effect, though 78 bpm is normal.
Question 2 of 5
The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?
Correct Answer: B
Rationale: Hypokalemia enhances digoxin's cardiac effects, increasing toxicity risk, so potassium levels must be monitored closely.
Question 3 of 5
The nurse is caring for a client who is taking atorvastatin (Lipitor) to assist in lowering his LDL cholesterol. Which lab value must be routinely done with this medication to prevent complications?
Correct Answer: C
Rationale: Atorvastatin can elevate liver enzymes, so routine liver function tests detect potential hepatotoxicity early.
Question 4 of 5
A nurse is caring for a client admitted to the intensive care unit for a cardiac dysrhythmia. The nurse understands the prescribed calcium channel blocker has which of the following mechanisms of action?
Correct Answer: C
Rationale: Calcium channel blockers reduce heart contractility and conduction, slowing heart rate and managing dysrhythmias effectively.
Question 5 of 5
A nurse prepares to administer vancomycin 15 mg/kg/day divided equally every 12 hr. The client weighs 198 lb. How many mg should the nurse administer with each dose? (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: Calculated: 198 lb ÷ 2.2 = 90 kg; 15 mg/kg/day × 90 kg = 1350 mg/day; 1350 ÷ 2 = 675 mg per dose.
