1. A 45-year-old male patient with a history of

hypertension and diabetes presents to the emergency

department with chest pain, dyspnea, and diaphoresis. He is

diagnosed with an acute myocardial infarction (AMI) and

is given aspirin, nitroglycerin, morphine, and oxygen. He is

also scheduled for an urgent coronary angioplasty. As a

nurse, what is the most important intervention to monitor

his condition and prevent complications?

A) Assess his vital signs every 15 minutes

B) Administer heparin infusion as ordered

C) Monitor his cardiac rhythm continuously

D) Educate him about lifestyle modifications

Answer: C) Monitor his cardiac rhythm continuously

Rationale: Monitoring the cardiac rhythm continuously is

the most important intervention to detect and treat any

arrhythmias that may occur after an AMI, which can be

life-threatening. Assessing vital signs, administering

heparin, and educating the patient are also important, but

not as urgent as monitoring the cardiac rhythm.

2. A 65-year-old female patient with a history of chronic

obstructive pulmonary disease (COPD) and osteoporosis is

admitted to the medical-surgical unit with pneumonia. She

has a productive cough, fever, and tachypnea. She is

receiving antibiotics, bronchodilators, and corticosteroids.

As a nurse, what is the most appropriate nursing diagnosis

for this patient?

A) Impaired gas exchange related to decreased lung

function
