1. What is the primary function of surfactant in the lungs?

Correct answer: A

Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.

2. What should the nurse do to complete a focused assessment for a female client with inflamed and painful hemorrhoids?

Correct answer: D

Rationale: Asking the client about the duration of discomfort related to hemorrhoids is the best intervention to implement for a focused assessment. This information provides important context for assessing the severity and chronicity of the condition, which is crucial for developing an appropriate care plan. Choices A, B, and C do not directly address the need to gather information about the duration of symptoms, which is essential for understanding the client's condition.

3. A client confides to the nurse that the client has been substituting herbal supplements for high blood pressure instead of the prescribed medication. How should the nurse respond first?

Correct answer: A

Rationale: The correct answer is to ask the client's reason for choosing to take herbs instead of prescribed medication. Understanding the client's rationale for using herbal supplements allows the nurse to explore any misconceptions and provide education on the importance of the prescribed medication. Choice B is incorrect because simply reinforcing the prescription does not address the client's concerns or reasons for using herbal supplements. Choice C does not directly address the immediate concern of the client substituting medication with herbal supplements. Choice D focuses on the risks of not taking the prescribed medication rather than herbal supplements, which is not the most appropriate initial response.

4. A nurse is caring for a client with schizophrenia who continues to repeat the last words heard. Which nursing problem should the nurse document in the medical record?

Correct answer: D

Rationale: The correct answer is D: Disturbed thought processes. Echolalia, or the repetition of words, is indicative of disturbed thought processes, a common symptom in clients with schizophrenia. Choice A (Altered thought processes) is a more appropriate term than 'Disturbed thought processes' to describe the issue of echolalia. Choice B (Impaired social interaction) is not the best option in this scenario as echolalia is not primarily a social interaction issue. Choice C (Risk for self-directed violence) is not directly related to the symptom described in the question, which is echolalia, indicating a disturbance in thought processes.

5. Which task could the nurse safely delegate to the UAP?

Correct answer: A

Rationale: The correct answer is A because oral feeding of a stable child is a task that can be safely delegated to a UAP. This task does not require nursing assessment or clinical judgment. Choice B involves assessment, which requires the nurse's clinical judgment. Choice C involves recording client goals during staff rounds, which may require interpretation and understanding of the goals set. Choice D involves evaluating a client's pain following medication administration, which requires assessment and clinical judgment by a nurse.
