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. A middle-aged woman talks to the nurse in the healthcare provider's office about uterine fibroids, also called leiomyomas or myomas. What statement by the woman indicates more education is needed?

• A. I am one out of every 4 women that get fibroids, and among women my age, between the 30s or 40s, fibroids occur more frequently.
• B. My fibroids are noncancerous tumors that grow slowly.
• C. The associated problems I have had are pelvic pressure and pain, urinary incontinence, frequent urination or urine retention, and constipation.
• D. Fibroids that cause no problems still need to be taken out.

Correct answer: D

Rationale: The correct answer is D because fibroids that do not cause symptoms do not necessarily need to be removed unless they pose other health risks. Choice A provides accurate information about the prevalence of fibroids among women of the woman's age group. Choice B correctly describes fibroids as noncancerous tumors. Choice C lists common symptoms associated with fibroids, which is relevant information. However, choice D is incorrect as fibroids that are asymptomatic or not causing problems usually do not require treatment, unless they lead to complications or health risks.

3. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

4. A client with multiple sclerosis is admitted with an acute exacerbation. What is the nurse's priority action?

• A. Monitor the client’s vital signs every hour.
• B. Assess for changes in the client’s muscle strength.
• C. Administer prescribed corticosteroids to reduce inflammation.
• D. Educate the client on managing fatigue and preventing relapses.

Correct answer: C

Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.

5. The nurse is providing discharge instructions to a client after a total hip replacement. Which statement by the client indicates a need for further teaching?

• A. I will avoid crossing my legs when sitting.
• B. I will use a raised toilet seat to prevent bending too far.
• C. I should keep my legs together to prevent dislocation.
• D. I will use a walker when moving around initially.

Correct answer: C

Rationale: The correct answer is C. Clients who have had a hip replacement should not keep their legs together to prevent dislocation. This position increases the risk of hip dislocation. Choices A, B, and D are correct statements. Avoiding crossing legs, using a raised toilet seat to prevent excessive bending, and using a walker when moving around initially are all appropriate measures to ensure proper recovery and prevent complications after a total hip replacement.
