ATI Pharmacology Exam 2 Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has atrial fibrillation and receives digoxin daily. Before administering this medication, which of the following actions should the nurse take?
Correct Answer: C
Rationale: Digoxin can cause bradycardia. Measuring the apical pulse for one minute ensures the heart rate is safe (above 60 bpm) before administration, unlike weighing, blood pressure, or snacks.
Question 2 of 5
A nurse is reviewing laboratory results of a client who has atrial fibrillation and is taking warfarin. For which of the following results should the nurse notify the provider?
Correct Answer: C
Rationale: PT 45 seconds indicates excessive anticoagulation, increasing bleeding risk, requiring provider notification, unlike normal platelet, Hct, or Hgb values.
Question 3 of 5
A nurse is caring for a client who has hypertension and asks the nurse about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients who have a history of which of the following conditions?
Correct Answer: C
Rationale: Propranolol, a nonselective beta-blocker, can cause bronchoconstriction, contraindicating it in asthma, unlike migraines, glaucoma, or depression.
Question 4 of 5
A nurse is monitoring a client who is receiving a unit of packed RBCs following surgery. Which of the following assessments is an indication that the client might be experiencing a hemolytic reaction?
Correct Answer: C
Rationale: Dyspnea indicates a hemolytic reaction due to hemoglobin release into the bloodstream, causing respiratory distress. Vomiting, flushing, and hypotension are less specific to hemolysis.
Question 5 of 5
A nurse is completing a medical interview with a client who has elevated cholesterol levels and takes warfarin. The nurse should recognize that which of the following actions by the client can potentiate the effects of warfarin?
Correct Answer: D
Rationale: Garlic's antiplatelet properties enhance warfarin's anticoagulant effect, increasing bleeding risk, unlike low-fat diets, grapefruit juice, or flax seeds.
