Cardiovascular NCLEX Questions Questions
Question 1 of 9
Blood from the stomach and intestines is transported to the liver by the:
Correct Answer: C
Rationale: The hepatic portal vein carries nutrient-rich, deoxygenated blood from the GI tract to the liver.
Question 2 of 9
Which of the following phases of cardiac cycle follows immediately after the beginning of the QRS wave?
Correct Answer: D
Rationale: The QRS wave marks ventricular depolarization, followed by isovolumic contraction as ventricles begin to contract.
Question 3 of 9
A patient has come to the clinic for a follow-up assessment that will include a BP reading. To ensure an accurate reading, the nurse should confirm that the patient has done which of the following?
Correct Answer: A
Rationale: Prior to the nurse assessing the patient's BP, the patient should try to rest quietly for 5 minutes. The forearm should be positioned at heart level. Caffeine products and cigarette smoking should be avoided for at least 30 minutes prior to the visit. Recent fluid intake is not normally relevant.
Question 4 of 9
Which of the following is a main branch of the subclavian artery?
Correct Answer: D
Rationale: The subclavian artery gives rise to the vertebral artery and internal thoracic artery, but not the occipital artery (a branch of the external carotid).
Question 5 of 9
Which of the following vessels has the greatest total cross-sectional area in the circulatory system?
Correct Answer: C
Rationale: Capillaries have the greatest total cross-sectional area, facilitating exchange.
Question 6 of 9
What is the best action if a client with a history of heart failure prescribed spironolactone and lisinopril has a potassium level of 5.8 mEq/L?
Correct Answer: B
Rationale: Spironolactone and lisinopril both increase potassium levels, and a level of 5.8 mEq/L indicates hyperkalemia.
Question 7 of 9
Which statement does not accurately describe veins?
Correct Answer: D
Rationale: This is because the pulmonary vein carries oxygenated blood from the lungs to the left ventricle.
Question 8 of 9
Which of the following blood vessel is used to distribute oxygenated blood to the myocardium?
Correct Answer: A
Rationale: The coronary arteries deliver oxygenated blood to the myocardium, ensuring that the heart muscle receives the oxygen it needs to function effectively.
Question 9 of 9
An abnormally wide (more than 0.10 second) QRS complex is characteristic of
Correct Answer: D
Rationale: The QRS of the premature complex is prolonged (greater than 0.10 second) and bizarre in appearance. Paroxysmal atrial tachycardia does not display a QRS complex that is greater than 0.10 seconds. Supraventricular tachycardia does not display a wide QRS complex. Escape rhythms may have a P wave that is inverted and located before, during, or after the QRS.
