Cardiovascular NCLEX Questions Questions
Question 1 of 5
A patient is diagnosed with left-sided systolic dysfunction heart failure. Which of the following is an expected finding with this condition?
Correct Answer: D
Rationale: Left-sided systolic dysfunction is characterized by a reduced ejection fraction (typically <40%, as in A) and symptoms like nocturnal paroxysmal dyspnea (C) due to pulmonary congestion. An ejection fraction of 65% (B) is normal.
Question 2 of 5
Release of norepinephrine from nerve fibers causes
Correct Answer: C
Rationale: Norepinephrine, a sympathetic neurotransmitter, increases both heart rate (chronotropic effect) and contractility (inotropic effect).
Question 3 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 4 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.
Question 5 of 5
Regarding ECG changes, which is CORRECT?
Correct Answer: D
Rationale: In hypercalcaemia, the increased calcium levels enhance myocardial contractility by increasing the availability of calcium during contraction.
