Cardiovascular Physiology Practice Questions Questions
Question 1 of 5
An important outcome of care for a female client with hypertension has been met when the client is able to do which of the following?
Correct Answer: A
Rationale: Step-by-step rationale for choice A being correct: 1. Return to her usual activities of daily living indicates improved health and well-being. 2. Managing hypertension should not significantly impact daily activities if controlled. 3. Indicates successful management and adherence to treatment plan. Summary of the incorrect choices: B. Identifying actions to counteract risk factors is important but not the key outcome in the question. C. Lowering blood pressure by a specific percentage is not as relevant as overall improvement in daily living. D. Discontinuing lifestyle modifications would be detrimental to managing hypertension effectively.
Question 2 of 5
There are no "P" waves at all in this rhythm and the other components are normal. This rhythm is most likely
Correct Answer: B
Rationale: The absence of "P" waves suggests the impulse is not originating from the sinus node (A). In a junctional rhythm (B), the impulse originates from the AV node, resulting in the absence of "P" waves. Atrial fibrillation (C) would show irregularly spaced "P" waves due to chaotic atrial activity. A ventricular rhythm (D) would have widened QRS complexes without preceding "P" waves. Thus, based on the absence of "P" waves and normal other components, a junctional rhythm is the most likely explanation.
Question 3 of 5
Which sign is characteristic of cardiac tamponade?
Correct Answer: B
Rationale: The correct answer is B: Beck's triad. Beck's triad consists of hypotension, distended neck veins, and muffled heart sounds, which are classic signs of cardiac tamponade. Hypotension results from decreased cardiac output due to compression of the heart by the fluid in the pericardial sac. Distended neck veins occur due to increased venous pressure from impaired right heart filling. Muffled heart sounds are heard because the fluid around the heart dampens sound transmission. Shortness of breath (Choice A) is a non-specific symptom and can be present in various cardiac conditions. Holosystolic murmur (Choice C) and bounding peripheral pulse (Choice D) are not characteristic of cardiac tamponade.
