Cardiovascular NCLEX Questions Questions
Question 1 of 5
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.
Question 2 of 5
After the nurse teaches the patient with stage 1 hypertension about diet modifications, which diet choice indicates that the teaching has been most effective?
Correct Answer: C
Rationale: For the prevention of hypertension, the Dietary Approaches to Stop Hypertension(DASH) recommendations include increasing the intake of calcium-rich foods. Caffeine restriction and decreased protein intake are not part of the recommendations. Nuts are high in beneficial nutrients and 4 to 5 servings weekly are recommended in the DASH diet.

Question 4 of 5
The nurse is assessing a patient who has been admitted to the intensive care unit(ICU) with a hypertensive emergency. Which finding is most important to report to the health care provider?
Correct Answer: B
Rationale: The patient's inability to move the left arm and leg indicates that a hemorrhagic stroke may be occurring and will require immediate action to prevent further neurologic damage. The other clinical manifestations are also likely caused by the hypertension and will require rapid nursing actions, but they do not require action as urgently as the neurologic changes.
Question 5 of 5
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.
