Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. Twenty minutes after beginning a heat application, the client states that the heating pad no longer feels warm enough. What is the best response by the nurse?

• A. That means you have derived the maximum benefit, and the heat can be removed.
• B. Your blood vessels are becoming dilated and removing the heat from the site.
• C. We will increase the temperature by 5 degrees when the pad no longer feels warm.
• D. The body's receptors adapt over time as they are exposed to heat.

Correct answer: D

Rationale: Choice (D) describes thermal adaptation, which occurs 20 to 30 minutes after heat application. The body's receptors adjust to the constant heat exposure, leading to a decreased sensation of warmth. Choices (A) and (B) provide inaccurate information regarding the situation, while choice (C) is not physiologically sound and could potentially harm the client by increasing the temperature unnecessarily.

3. Which action should the nurse implement when using the confrontation technique during a vision exam?

• A. Use an ophthalmoscope to observe the client's pupil constriction when a strong light is shone on it.
• B. Stand behind the client and direct the client to report when an object enters the peripheral field of vision.
• C. Display a series of four cards with printing of varying sizes to the client and ask which card the client sees most clearly.
• D. Sit facing the client, look directly at the client's face, and move an object inward from the periphery.

Correct answer: D

Rationale: During a vision exam, the confrontation technique is used to assess peripheral vision. By sitting facing the client and moving an object inward from the periphery while looking directly at the client's face, the nurse allows the client to indicate when the object enters the visual field. This method helps in determining the extent of the client's peripheral vision accurately. Choices A, B, and C are incorrect as they do not describe the appropriate method for using the confrontation technique during a vision exam. Choice A involves using an ophthalmoscope to observe pupil constriction, choice B involves testing the peripheral field of vision without the confrontation technique, and choice C describes the Snellen eye chart test for visual acuity, which is not related to the confrontation technique.

4. A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulation therapy. Which statement by the client indicates a need for further teaching?

• A. I should avoid eating green leafy vegetables.
• B. I should wear loose-fitting clothes to avoid pressure on my legs.
• C. I should avoid prolonged sitting or standing.
• D. I should continue taking my over-the-counter herbal supplements.

Correct answer: D

Rationale: The statement 'I should continue taking my over-the-counter herbal supplements' (D) indicates a need for further teaching because some herbal supplements can interact with anticoagulants, increasing the risk of bleeding. It is crucial to inform healthcare providers about all medications, including herbal supplements, to prevent adverse interactions. The other statements reflect appropriate understanding of precautions related to DVT and anticoagulation therapy.

5. The healthcare provider assesses a 2-year-old who is admitted for dehydration and finds that the peripheral IV rate by gravity has slowed, even though the venous access site is healthy. What should the healthcare provider do next?

• A. Apply a warm compress proximal to the site.
• B. Check for kinks in the tubing and raise the IV pole.
• C. Adjust the tape that stabilizes the needle.
• D. Flush with normal saline and recount the drop rate.

Correct answer: B

Rationale: In this scenario, the appropriate next step for the healthcare provider is to check for kinks in the tubing and raise the IV pole. These issues can commonly cause a slowed IV rate. Applying a warm compress (Choice A) may not address the underlying problem of kinked tubing or incorrect IV pole height. Adjusting the tape that stabilizes the needle (Choice C) is important for securement but is not the priority in this situation. Flushing with normal saline and recounting the drop rate (Choice D) should only be done after ruling out mechanical issues like kinks in the tubing.
