1. What is the function of villi and microvilli in the GI tract?

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

2. Which is NOT a prudent recommendation for a menopausal patient?

Correct answer: A

Rationale: Excessive supplementation of calcium and vitamin D beyond the upper intake level is not recommended unless under medical supervision, as it can cause adverse health effects.

3. During the phallic stage, with which parent must the child identify?

Correct answer: A

Rationale: According to Freud's psychosexual development theory, during the phallic stage (approximately ages 3 to 6), the child starts to identify with the parent of the same sex. This identification is a crucial part of the child's development and is believed to influence their adult behavior. The process involves the child adopting the characteristics, attitudes, and values of the same-sex parent. Choice B, C, and D are incorrect as they do not align with Freud's theory of the phallic stage of psychosexual development.

4. The counting of sponges is done by the Surgeon together with the:

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. During blood administration, what is essential for the nurse to do in order to carefully monitor for adverse reactions?

Correct answer: A

Rationale: In the context of blood administration, it's crucial for the nurse to stay with the client for the first 15 minutes. This is because most adverse reactions are likely to occur within this initial period. Monitoring the client closely during this time allows for immediate detection and response to any potential reactions. Choice B, staying with the client for the entire period of blood administration, is not typically feasible or necessary, although regular checks should be conducted. Running the infusion at a faster rate during the first 15 minutes (Choice C) is incorrect as this can actually increase the risk of adverse reactions. Informing the client to notify the staff immediately for any adverse reaction (Choice D) is an important practice, but it is not the most direct way for the nurse to monitor for adverse reactions.
