ATI Nurs 180 Pharmacology Quiz Questions
Extract:
Question 1 of 5
A client who has just experienced a pulmonary embolism is administered alteplase (Activase). Which of the following side effects associated with this medication would the nurse assess for?
Correct Answer: D
Rationale: Internal bleeding is a major risk with thrombolytics like alteplase due to their clot-dissolving action. Pancytopenia, hypertension, and hypokalemia are not directly associated.
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: A
Rationale: Hypokalemia increases the risk of digoxin toxicity by enhancing its cardiac effects. The other imbalances are less directly related.
Question 3 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, helping manage dysrhythmias. They do not act on beta cells, increase heart rate, or directly increase oxygen circulation.
Question 4 of 5
A client newly prescribed niacin reports flushing after their first dose. Which medication would the nurse anticipate administering to manage this side effect?
Correct Answer: C
Rationale: NSAIDs, such as ibuprofen, reduce niacin-induced flushing by inhibiting prostaglandins. The other medications do not address this side effect.
Question 5 of 5
A nurse is preparing 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: The client's weight (198 lb) converts to 90 kg (198 / 2.2). The dose is 15 mg/kg/day, or 1350 mg/day (15 * 90). Divided every 12 hours, each dose is 675 mg (1350 / 2).
