Nursing Elites

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 client with hyperthyroidism is admitted for total thyroidectomy. What is the nurse's priority post-operative intervention?

• A. Monitor the client's calcium levels for hypocalcemia.
• B. Monitor for signs of respiratory distress.
• C. Administer oral calcium supplements.
• D. Elevate the head of the bed to 45 degrees.

Correct answer: A

Rationale: The correct answer is to monitor the client's calcium levels for hypocalcemia. After a total thyroidectomy, there is a risk of accidental removal or damage to the parathyroid glands, leading to hypocalcemia. This complication can manifest within the first 24-48 hours post-op. Monitoring calcium levels is crucial to prevent serious complications such as tetany or seizures. While monitoring for respiratory distress is important, it is not the priority in this case. Administering oral calcium supplements should only be done based on the healthcare provider's prescription and after assessing the client's calcium levels. Elevating the head of the bed to 45 degrees is beneficial for respiratory function but is not the priority intervention for a client at risk for hypocalcemia post-thyroidectomy.

3. The nurse has completed the diet teaching of a client who is being discharged following treatment of a leg wound. A high-protein diet is encouraged to promote wound healing. Which lunch choice by the client indicates that the teaching was effective?

• A. A tuna fish sandwich with chips and ice cream
• B. A vegetable salad with croutons and ranch dressing
• C. A grilled chicken breast with steamed vegetables
• D. A peanut butter and jelly sandwich with soda

Correct answer: C

Rationale: The correct answer is C. Grilled chicken is an excellent source of protein, which is important for wound healing. Choices A, B, and D are less ideal for wound healing. Choice A contains high-fat and high-sugar components like chips and ice cream, which may not support wound healing effectively. Choice B includes croutons and ranch dressing, which may not provide as much protein as needed for wound healing. Choice D with a peanut butter and jelly sandwich and soda lacks a balanced meal with adequate protein to promote wound healing.

4. A client presents to the labor and delivery unit with a report of leaking fluid that is greenish-brown vaginal discharge. Which action should the nurse take first?

• A. Notify the healthcare provider immediately
• B. Begin continuous fetal monitoring
• C. Check the amniotic fluid pH
• D. Assess maternal vital signs

Correct answer: B

Rationale: Greenish-brown discharge likely indicates meconium in the amniotic fluid, which poses a risk to the fetus. Continuous fetal monitoring should be initiated immediately to assess for signs of fetal distress. Meconium-stained amniotic fluid can lead to meconium aspiration syndrome in the newborn, so timely monitoring is crucial. Checking the amniotic fluid pH can help confirm the presence of meconium but is not the priority over fetal monitoring. Assessing maternal vital signs is important but secondary to monitoring the fetal well-being in this urgent situation. Notifying the healthcare provider can follow once the immediate fetal assessment is underway.

5. After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?

• A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
• B. Listen with the bell of the stethoscope at the same location
• C. Listen at a different location over the aortic area
• D. Switch to the apical area and reassess for S3 sounds

Correct answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.
