1. What is the primary function of hemoglobin in red blood cells?

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.

2. The mother of a 9-month-old child diagnosed with respiratory syncytial virus (RSV) yesterday calls the clinic to inquire if it will be all right to take her infant to a friend's child's first birthday party the following day. Which response should the nurse provide?

Correct answer: A

Rationale: The correct response is A: 'Do not expose other children as the virus is very contagious even without direct contact.' RSV is highly contagious, especially in young children. Allowing the infected child to attend a birthday party can put other children at risk of contracting the virus. Choice B is incorrect as RSV can remain contagious for a period of time. Choice C is not sufficient, as wearing a mask may not entirely prevent the spread of the virus. Choice D is inaccurate, as children under 5 months are not the only ones susceptible to RSV; all young children are at risk.

3. The PN observes a UAP bathing a bedfast client with the bed in the high position. Which action should the PN take?

Correct answer: D

Rationale: The correct action for the PN to take in this situation is to instruct the UAP to lower the bed for safety. Keeping the bed in the lowest position during care activities is crucial for preventing falls and injuries to both the client and the caregiver. Instructing the UAP to lower the bed addresses the immediate safety concern. Choice A is incorrect because simply supervising the UAP without addressing the unsafe bed height does not ensure the client's safety. Choice B is incorrect as the priority is to address the safety concern rather than offering assistance to the UAP. Choice C is incorrect as assuming care of the client immediately does not address the root issue of the high bed position.

4. The UAP reports to the PN that a client refused to bathe for the third consecutive day. Which action is best for the PN to take?

Correct answer: D

Rationale: The best action for the PN to take when a client refuses to bathe is to ask the client why the bath was refused. Understanding the client's reasons for refusing a bath is crucial as it helps to address any underlying issues, such as fear, discomfort, or physical limitations. By communicating directly with the client, the PN can provide appropriate care tailored to the client's needs. Choices A, B, and C do not directly address the root cause of the refusal and may not effectively resolve the issue.

5. In obtaining an orthostatic vital sign measurement, what action should the nurse take first?

Correct answer: C

Rationale: The correct first action when obtaining an orthostatic vital sign measurement is to instruct the client to lie supine. This allows for establishing a baseline measurement of vital signs before any positional changes. Counting the client's radial pulse (Choice A) is a step that follows after the initial supine position to assess changes in pulse rate. Applying a blood pressure cuff (Choice B) and assisting the client to stand upright (Choice D) are actions that come later in the process after the baseline measurements are obtained in the supine position.
