Question 1 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?

Question 2 of 5
A nurse is teaching a client who has angina pectoris about starting therapy with sublingual (SL) nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: B
Rationale: Sublingual nitroglycerin is taken at chest pain onset for rapid relief, not with water, every 15 minutes, or routinely after meals.
Question 3 of 5
A nurse is caring for a client who is to receive a unit of packed RBCs. The nurse should prime the blood administration tubing using which of the following IV solutions?
Correct Answer: B
Rationale: 0.9% sodium chloride is isotonic, preventing RBC hemolysis, unlike dextrose or lactated Ringer's, which can cause complications.
Question 4 of 5
A nurse is reviewing the health history for a client who has angina pectoris and a prescription for propranolol hydrochloride PO 40 mg twice daily. Which of the following findings in the history should the nurse report to the provider?
Correct Answer: C
Rationale: Propranolol is contraindicated in asthma due to bronchoconstriction risk, unlike hypertension, hypothyroidism, or migraines (treated by propranolol).
Question 5 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.
