A client is admitted to the emergency room with chest pain and a suspected diagnosis of acute myocardial infarction (MI). Which test would the nurse expect the physician to order to make a definitive diagnosis of MI?

Choice A rationale

Taking nitroglycerin when experiencing chest pain is correct as it helps to relieve the pain by dilating blood vessels and increasing blood flow to the heart.

Choice B rationale

Calling 911 if chest pain does not improve after taking nitroglycerin is correct and necessary to seek immediate medical assistance.

Choice C rationale

Storing nitroglycerin tablets in a dark, cool place is correct to maintain their potency, as light and heat can degrade the medication.

Choice D rationale

Taking up to three doses of nitroglycerin five minutes apart is correct; however, if the pain persists after one dose, the patient should call 911 immediately rather than waiting for all three doses to be taken.

Choice A rationale

Hypertension is not typically a sign of heart failure related to cor pulmonale. It is more associated with systemic issues rather than pulmonary complications.

Choice B rationale

Peripheral edema is a common sign of heart failure and cor pulmonale due to increased pressure in the venous system, leading to fluid accumulation in the tissues.

Choice C rationale

Increased respiratory rate may occur but is not specific to heart failure in cor pulmonale.

Choice D rationale

Cough with pink-tinged sputum is more indicative of pulmonary edema related to left-sided heart failure rather than cor pulmonale.
