Nursing Elites

1. The client is receiving intravenous dopamine. What is the most important nursing assessment?

• A. Monitor heart rate and rhythm
• B. Monitor blood pressure
• C. Monitor respiratory rate
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct answer is to monitor heart rate and rhythm when a client is receiving intravenous dopamine. Dopamine is known to potentially cause arrhythmias, making this assessment crucial. While monitoring blood pressure, respiratory rate, and oxygen saturation are important nursing assessments, they are not the most critical when dopamine is being administered.

2. The nurse is giving digoxin to a client. What is the most important parameter to check before administration?

• A. Heart rate
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, an abnormally slow heart rate. Monitoring the heart rate is essential to prevent potential complications associated with digoxin therapy. Choices B, C, and D are less critical parameters to assess before administering digoxin. While blood pressure is also important to monitor during digoxin therapy, the most crucial parameter to check due to the medication's potential effect on heart rate is the heart rate itself.

3. What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?

• A. Aortic aneurysm
• B. Arterial stenosis
• C. Pulmonary embolism
• D. Deep vein thrombosis

Correct answer: A

Rationale: An aortic aneurysm is a condition characterized by the weakening and bulging of the aorta, the body's main artery. If left untreated, this bulging may lead to a rupture, causing severe complications. Arterial stenosis refers to the narrowing of an artery, not the weakening and bulging seen in an aortic aneurysm. Pulmonary embolism involves a blockage in the pulmonary artery, which is different from the weakening and bulging in an aortic aneurysm. Deep vein thrombosis is the formation of a blood clot in a deep vein, not related to the condition described in the question.

4. Which medication is used to prevent blood clots by thinning the blood, reducing the risk of stroke and heart attack?

• A. Anticoagulant
• B. ACE inhibitor
• C. Beta-blocker
• D. Calcium channel blocker

Correct answer: A

Rationale: The correct answer is 'Anticoagulant.' Anticoagulants are medications specifically designed to prevent blood clots by thinning the blood, which effectively reduces the risk of stroke, heart attack, and other cardiovascular events. Choices B, C, and D, which are ACE inhibitors, beta-blockers, and calcium channel blockers, respectively, do not have the primary mechanism of action to prevent blood clot formation. ACE inhibitors, beta-blockers, and calcium channel blockers are commonly used for managing hypertension and other cardiovascular conditions by different mechanisms of action.

5. What term describes the phenomenon wherein decreased BP causes a reflex SNS response with increased pulse, increased contractility, and vasoconstriction; and increased BP causes reflex vagal responses resulting in decreased heart rate and passive vasodilation in the systemic arterioles?

• A. Baroreflex
• B. Cheyne-Stokes breathing
• C. Frank-Starling Law
• D. Starling reflex

Correct answer: A

Rationale: The correct answer is A: Baroreflex. The Baroreflex is a mechanism by which the body maintains blood pressure homeostasis through reflexive adjustments in heart rate and vascular tone. Choice B, Cheyne-Stokes breathing, is a pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing. Choices C and D, Frank-Starling Law and Starling reflex, are related to the intrinsic ability of the heart to adjust its output based on venous return, not specifically regulating blood pressure through reflex adjustments in heart rate and vascular tone as seen in the described phenomenon.
