Nursing Elites

1. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

• A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
• B. The antagonistic interaction of the medications has reduced their effectiveness.
• C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
• D. The additive effect of the medications has lowered the blood pressure too much.

Correct answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

2. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

3. A client with a recent myocardial infarction is prescribed a beta-blocker. What side effect should the nurse monitor for?

• A. Monitor the client for bradycardia.
• B. Check the client’s blood pressure for signs of hypotension.
• C. Monitor the client for signs of hyperglycemia.
• D. Monitor for signs of fluid retention.

Correct answer: B

Rationale: The correct answer is B: 'Check the client’s blood pressure for signs of hypotension.' Beta-blockers can lead to decreased heart rate, but bradycardia is not the primary side effect to monitor. Monitoring for bradycardia is more relevant when administering medications like digoxin. Hyperglycemia is associated with medications like corticosteroids, not beta-blockers. Fluid retention is a side effect seen with medications like corticosteroids or calcium channel blockers, not beta-blockers. Therefore, in a client taking a beta-blocker after a myocardial infarction, monitoring for hypotension is crucial due to the medication's mechanism of action.

4. A client who recently received a prescription for ramelteon to treat sleep deprivation reports experiencing several side effects since taking the drug. Which side effect should the nurse report to the healthcare provider?

• A. Somnambulism
• B. Dry mouth
• C. Vivid dreams
• D. Daytime sleepiness

Correct answer: A

Rationale: The correct answer is A, 'Somnambulism' (sleepwalking). Somnambulism is a potentially dangerous side effect that should be reported to the healthcare provider immediately. Sleepwalking can pose risks to the individual's safety and may indicate a serious adverse reaction to the medication. Dry mouth (choice B), vivid dreams (choice C), and daytime sleepiness (choice D) are common side effects of ramelteon and are generally not considered as urgent or serious as somnambulism. While these side effects can impact the client's quality of life, they are not typically associated with immediate safety concerns.

5. A client with atrial fibrillation is prescribed warfarin. Which instruction should the nurse include in the teaching?

• A. Maintain a consistent intake of leafy green vegetables
• B. Use an electric razor when shaving
• C. Monitor blood pressure daily
• D. Avoid eating bananas and oranges

Correct answer: B

Rationale: Clients on warfarin are at increased risk of bleeding due to its anticoagulant effects. Using an electric razor reduces the risk of cuts and bleeding, which is an important safety precaution. While leafy greens should not be avoided, their intake should be consistent to maintain a stable level of vitamin K in the body. Monitoring blood pressure daily is important for other conditions but not directly related to warfarin therapy. Avoiding bananas and oranges is not a standard instruction for clients on warfarin.
