Question

The practical nurse in the emergency department (ED) is caring for a 72-year-old male client.

Answer 1

Correct Answers:

Provide reassurance and a calm presence.
Use clear and simple language when communicating.

Rationale :

🧘Providing reassurance and a calm presence helps reduce sympathetic stimulation that worsens cardiac stress and anxiety.

🗣️Using clear and simple language enhances comprehension, particularly in a high-stress, medically complex situation.

⚠️Encouraging isolation can increase feelings of fear or abandonment and should be avoided in anxious patients.

🧩Focusing solely on physical symptoms or using complex medical jargon may lead to increased confusion and agitation.

📌Core Message

Calm reassurance and clear communication are essential strategies to manage acute anxiety in medically unstable patients.

Answer 2

Correct Answers

Expressing anxiety about his medical condition [ Not indicated ]
Becoming confused and disoriented [ Indicated ]
Expressing pain and discomfort [ Not indicated ]
Requesting information about treatment options [ Not indicated ]

Rationale :

🧠Sudden confusion and disorientation represent a true change in mental status and may indicate hypoxia, acidosis, or neurological decline.

😟Expressing anxiety about illness is expected in acute illness and not a deviation from baseline mental function.

😣Pain and discomfort are subjective symptoms of illness but not inherently a sign of altered cognition or mental status.

💬Requesting treatment information indicates awareness and orientation, not cognitive impairment.

📌Core Message

Only confusion and disorientation are true indicators of altered mental status, not anxiety, pain, or treatment inquiries.

Answer 3

Correct Answers:

Atherosclerosis

Rationale :

🧱Atherosclerosis, or the buildup of plaque in arterial walls, is the primary cause of CAD.

🧬These plaques narrow arteries, reduce blood flow, and increase risk of ischemia and infarction.

📋While conditions like DM and MI increase risk or result from CAD, atherosclerosis is the root pathology.

💁‍♂️Controlling lipid levels is key in preventing CAD progression.

📌Core Message

Atherosclerosis is the most common cause of coronary artery disease, due to arterial plaque buildup.

Answer 4

Correct Answers:

Plaques obstruct the artery

Rationale :

🩸Atherosclerotic plaques form in the arterial walls, leading to narrowing and obstruction of blood flow.

🧱This restricts oxygen delivery to the heart muscle, contributing to angina and infarction.

🚫It is an arterial process, not venous, and the plaques form within the vessel lining.

🧠Understanding this mechanism is fundamental in managing and preventing CAD.

📌Core Message

Atherosclerosis impairs blood flow by forming plaques that obstruct the arteries, reducing oxygen delivery to the heart.

Answer 5

Correct Answers:

Heredity

Rationale :

🧬Heredity is a non-modifiable risk factor for coronary artery disease and refers to the genetic predisposition inherited from family.

🧠Unlike lifestyle or medical conditions, a patient’s family history cannot be altered or controlled.

📋While DM and hypertension can be managed, and smoking can be stopped, genetic risk persists regardless of interventions.

👨‍👩‍👧‍👦Patients with a strong family history should be encouraged to manage other modifiable risks aggressively.

📌Core Message

Heredity is a non-modifiable risk factor for coronary artery disease, unlike lifestyle or medical conditions.

Answer 6

Correct Answers:

200 mg/dl

Rationale :

🧪A total cholesterol level above 200 mg/dl is associated with an increased risk of atherosclerosis and coronary artery disease.

💁‍♂️High cholesterol promotes plaque buildup in coronary arteries, reducing oxygen delivery to the heart.

📊Levels should ideally remain below 200 mg/dl to minimize cardiovascular complications.

⚠️Monitoring and managing cholesterol is a key component of heart disease prevention.

📌Core Message

A cholesterol level over 200 mg/dl increases the likelihood of coronary artery disease and requires intervention.

Answer 7

Correct Answers:

Enhance myocardial oxygenation

Rationale :

🔴Oxygenation must be prioritized in clients with coronary artery disease, as the heart muscle is already under perfusion stress.

💓Lack of oxygen can worsen ischemia and lead to myocardial infarction or arrhythmias.

🚨Oxygen support and ensuring adequate ventilation are critical first steps before administering medications.

📋Education and anxiety reduction are important but come after stabilizing oxygen supply.

📌Core Message

The first priority in coronary artery disease is to enhance myocardial oxygenation to prevent tissue damage.

Answer 8

Correct Answers:

Percutaneous transluminal coronary angioplasty

Rationale :

🧯PTCA, also known as balloon angioplasty, is a minimally invasive procedure to open blocked coronary arteries.

💁‍♂️It’s a standard treatment to restore blood flow in patients with CAD and reduce symptoms like angina.

📈Unlike surgery, PTCA is less invasive and involves threading a balloon catheter through vessels to compress plaque.

🧠It’s a key part of interventional cardiology and often followed by stent placement.

📌Core Message

Percutaneous transluminal coronary angioplasty (PTCA) is a key medical procedure used to treat coronary artery disease.

Answer 9

Correct Answers:

Inferior

Rationale :

💁‍♂️The right coronary artery supplies the inferior wall of the heart, especially the right ventricle and parts of the inferior left ventricle.

⚠️A blockage here can cause inferior myocardial infarction, often associated with bradycardia and hypotension.

📊ECG changes in leads II, III, and aVF support the diagnosis of inferior MI.

🧠Knowledge of coronary anatomy helps localize infarcts and predict complications.

📌Core Message

Right coronary artery occlusion typically causes inferior wall infarction of the heart.

Answer 10

Correct Answers:

Chest pain

Rationale :

💔Chest pain, often described as crushing, squeezing, or pressure, is the hallmark symptom of myocardial infarction.

💁‍♂️It usually occurs substernally and may radiate to the arm, jaw, or back.

⚠️Pain indicates myocardial ischemia and requires immediate attention to prevent irreversible damage.

📋Other symptoms may occur, but pain is the most reliable and early indicator.

📌Core Message

The most common symptom of a myocardial infarction is chest pain, signaling heart muscle ischemia.
