Question 1 of 5
A nurse is teaching a client who has angina about nitroglycerin sublingual tablets. Which of the following statements should the nurse include in the teaching?
Correct Answer: B
Rationale: Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart. This action helps relieve the chest pain associated with angina by increasing blood flow.
Question 2 of 5
A nurse is providing teaching for a client who has a new diagnosis of angina pectoris. Which of the following information should the nurse include about anginal pain?
Correct Answer: B
Rationale: Exertion increases myocardial oxygen demand, while anxiety triggers a sympathetic response, both of which can precipitate anginal pain due to the heart's inability to meet increased oxygen requirements.
Question 3 of 5
A nurse is admitting a client who has acute heart failure following a myocardial infarction (MI). The nurse recognizes that which of the following prescriptions by the provider requires clarification?
Correct Answer: A

Examine the attached ECG image and identify the type of arrhythmia present. The ECG shows a series of wide QRS complexes occurring at a rapid rate.
Correct Answer: B
Rationale: Ventricular tachycardia is characterized by a rapid rate and wide QRS complexes. This rhythm originates in the ventricles and can lead to a decrease in cardiac output and possible deterioration into ventricular fibrillation.
Question 5 of 5
A client who has a history of myocardial infarction (MI) is prescribed aspirin 325 mg. The nurse recognizes that the aspirin is given due to which of the following actions of the medication?
