Questions 1–25: Preoperative Cardiac Surgery
1.
A patient is scheduled for coronary artery bypass grafting (CABG). Which preoperative
assessment is most important?
A. Hair color
B. Baseline cardiovascular and respiratory status
C. Favorite food
D. Sleep position
Answer: B. Baseline cardiovascular and respiratory status
Rationale: Baseline cardiac and respiratory findings provide comparison points for identifying
postoperative deterioration.
2.
The primary purpose of CABG is to:
A. Replace the aortic valve
B. Restore blood flow around obstructed coronary arteries
C. Remove the pericardium
D. Reduce blood volume
Answer: B. Restore blood flow around obstructed coronary arteries
,Rationale: CABG creates a bypass around significantly narrowed or blocked coronary arteries to
improve myocardial perfusion.
3.
Which vessel is commonly harvested from the leg for CABG?
A. Femoral artery
B. Great saphenous vein
C. Carotid artery
D. Pulmonary artery
Answer: B. Great saphenous vein
Rationale: The great saphenous vein is commonly used as a conduit for coronary bypass
grafting.
4.
Which arterial conduit is frequently used during CABG?
A. Internal mammary artery
B. Radial artery only in every patient
C. Femoral artery
D. Renal artery
Answer: A. Internal mammary artery
Rationale: The internal mammary artery is a commonly used arterial graft, particularly for the
left anterior descending coronary artery.
5.
Before cardiac surgery, which laboratory result is particularly important for identifying bleeding
risk?
A. Platelet count
B. Sodium only
C. Amylase
D. Bilirubin only
,Answer: A. Platelet count
Rationale: Platelets are essential for hemostasis, and thrombocytopenia increases bleeding risk.
6.
Which medication class may need special perioperative management because of bleeding risk?
A. Anticoagulants
B. Antacids
C. Multivitamins
D. Stool softeners
Answer: A. Anticoagulants
Rationale: Anticoagulants increase bleeding risk and require careful management before
invasive surgery.
7.
Which preoperative teaching is particularly important before sternotomy?
A. How to splint the chest during coughing
B. How to avoid all movement permanently
C. How to stop breathing during coughing
D. How to remove surgical drains independently
Answer: A. How to splint the chest during coughing
Rationale: Supporting the sternum during coughing can decrease discomfort while allowing
effective pulmonary hygiene.
8.
Why is pulmonary hygiene emphasized before cardiac surgery?
A. To increase blood glucose
B. To reduce postoperative respiratory complications
C. To prevent hypertension
D. To increase fluid retention
, Answer: B. To reduce postoperative respiratory complications
Rationale: Deep breathing, coughing, and incentive spirometry help prevent atelectasis and
pneumonia.
9.
Which patient statement demonstrates correct understanding of incentive spirometry?
A. "I will use it only if I develop chest pain."
B. "I will take slow, deep breaths through the device."
C. "I should blow forcefully into it."
D. "It replaces coughing completely."
Answer: B. "I will take slow, deep breaths through the device."
Rationale: Incentive spirometry encourages sustained deep inspiration and helps prevent
atelectasis.
10.
A patient awaiting CABG asks why smoking cessation is important. What is the best response?
A. "Smoking increases cardiovascular and pulmonary complications."
B. "Smoking only affects your skin."
C. "Smoking has no effect after surgery."
D. "Smoking increases your blood oxygen level."
Answer: A. "Smoking increases cardiovascular and pulmonary complications."
Rationale: Smoking contributes to impaired oxygenation, vascular disease, pulmonary
complications, and poor wound healing.
11.
Which assessment should be completed before administering a preoperative beta blocker?
A. Heart rate and blood pressure
B. Hair color
C. Bowel sounds only
D. Visual acuity
