1. 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.

2. The nurse is responsible for several elderly clients, including a client on bed rest with a skin tear and hematoma from a fall 2 days ago. What is the best care assignment for this client?

• A. Assign an RN to supervise a nursing assistant for skin care
• B. Assign a nursing assistant to help the client with self-care activities
• C. Delegate complete care to an unlicensed assistive personnel
• D. Supervise a nursing assistant for skin care

Correct answer: D

Rationale: In this scenario, the best care assignment for the client with a skin tear and hematoma is to supervise a nursing assistant for skin care. This ensures proper wound care while utilizing the skills of the nursing assistant effectively. Assigning an RN to supervise the nursing assistant is appropriate as it provides the necessary expertise for wound care supervision. Delegating complete care to an unlicensed assistive personnel may not be suitable for a client with specific wound care needs. Helping the client with self-care activities may not directly address the urgent need for proper wound care in this situation.

3. After administering a proton pump inhibitor, which action should the nurse take to evaluate the effectiveness of the medication?

• A. Monitor gastrointestinal pain
• B. Ask the client about pain levels
• C. Check the client's vital signs
• D. Assess for signs of bleeding

Correct answer: B

Rationale: The correct answer is to ask the client about pain levels. Proton pump inhibitors (PPIs) work by reducing stomach acid to alleviate gastrointestinal pain. By inquiring about the client's pain experience, the nurse can directly assess the effectiveness of the medication. Monitoring bowel movements (Choice A) is not directly related to evaluating the effectiveness of a PPI. Checking vital signs (Choice C) may not reflect the medication's effectiveness in reducing stomach acid. Assessing for signs of bleeding (Choice D) is important but not the most direct way to evaluate the effectiveness of a PPI.

4. 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.

5. A male client with HIV on saquinavir and other antiretrovirals reports increased hunger and thirst but weight loss. Which action should the nurse take?

• A. Use a glucometer to assess capillary glucose.
• B. Explain to the client that an increased dose of medication is needed.
• C. Reassure the client that weight will improve as viral load decreases.
• D. Teach the client how to measure his weight accurately.

Correct answer: A

Rationale: Increased thirst and hunger while losing weight may indicate hyperglycemia, a common side effect of saquinavir and other antiretrovirals. Using a glucometer to assess capillary glucose levels is essential to evaluate for hyperglycemia. Choice B is incorrect because increasing the dose of medication without assessing blood glucose levels can be dangerous. Choice C is incorrect because weight loss may not necessarily improve with viral load reduction and doesn't address the immediate concern of hyperglycemia. Choice D is irrelevant to the presenting symptoms and should not be a priority over assessing for hyperglycemia.
