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. When teaching a group of mothers of young children about emergency care for poisoning, which of the following statements should be included?

• A. Induce vomiting immediately after the poison ingestion
• B. Call the local Poison Control Center after inducing vomiting
• C. Call the Poison Control Center prior to any interventions
• D. Take the child to the emergency department before calling the Poison Control Center

Correct answer: C

Rationale: The correct statement to include when teaching about emergency care for poisoning is to call the Poison Control Center prior to any interventions. This is important because the Poison Control Center can provide guidance on the appropriate steps to take based on the type of poisoning, the amount ingested, and the age of the child. Inducing vomiting without professional advice can sometimes do more harm than good. Choice A is incorrect because inducing vomiting immediately is not recommended without consulting with professionals. Choice B is incorrect as it suggests calling the Poison Control Center after inducing vomiting, which is not the recommended sequence. Choice D is incorrect because it is advisable to contact the Poison Control Center first before taking the child to the emergency department.

3. The nurse is developing a plan of care for a client who reports tingling in the feet and who is newly diagnosed with peripheral vascular disease. Which outcome should the nurse include in the plan of care for this client?

• A. The client will walk 30 minutes three times a week
• B. The client will demonstrate understanding of proper shoe fit
• C. The client will perform foot care daily
• D. The client's blood pressure readings will be less than 160/90 mmHg

Correct answer: D

Rationale: Controlling blood pressure is critical in managing peripheral vascular disease, as elevated pressure can exacerbate vascular damage and complications. While foot care, shoe fit, and exercise are important, lowering blood pressure is a primary goal. Proper blood pressure management helps in preventing further damage to the blood vessels and reduces the risk of complications associated with peripheral vascular disease, making it the most crucial outcome to include in the plan of care for this client.

4. A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

5. Which statement made by the client indicates an understanding of the instructions regarding the administration of alendronate (Fosamax)?

• A. I will take the medication at bedtime to avoid stomach upset.
• B. I will take the medication with a full glass of water first thing in the morning.
• C. I will lie down for 30 minutes after taking the medication.
• D. I will take the medication with food to reduce stomach irritation.

Correct answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.
