Correct Answer: C

Rationale: The correct answer is C: Viral set point. The viral set point refers to the stable level of HIV in the body after the initial infection. This state indicates a balance between viral replication and the immune response. The other choices are incorrect because: A) Static stage implies no change, which is not the case with HIV levels fluctuating; B) Latent stage refers to a period of inactivity, not the stable state described; D) Window period is the time between infection and detectable antibodies, not the equilibrium state described.

Correct Answer: A

Rationale: The correct answer is A: Breech presentation. Obesity can lead to a larger fetus, increasing the risk of breech presentation. The rationale is that excess fat can hinder the baby's ability to turn head down. Other choices are incorrect because: B: Ectopic pregnancy is not related to obesity, C: Birth defects can be influenced by maternal health but are not directly linked to obesity, and D: Venous thromboembolism is more associated with immobility and hypercoagulable states rather than obesity.

Correct Answer: C

Rationale: The correct answer is C because folic acid is crucial in preventing neural tube defects and anemia in the developing fetus. The nurse should teach the expectant mother about the importance of taking folic acid supplements before and during pregnancy. Folic acid is essential for proper cell division and growth, reducing the risk of birth defects. Choice A is incorrect because calcium intake is important throughout pregnancy, not just in the first trimester. Choice B is incorrect as protein intake should be adequate to support maternal and fetal growth, not decreased. Choice D is incorrect as excessive intake of vitamins and minerals can be harmful to the mother and the baby. In summary, the expectant mother should be educated on the importance of folic acid supplementation to prevent birth defects and anemia, while also ensuring a balanced diet with all essential nutrients.

Correct Answer: A

Rationale: The correct answer is A: Serum albumin level. Serum albumin is an important indicator of nutritional status, as low levels may indicate malnutrition or inflammation commonly seen in AIDS patients. Weight history (B) is also relevant as weight changes can reflect nutritional status. White blood cell count (C) is not directly related to nutritional status. Body mass index (D) is a calculation based on weight and height, not a direct measure of nutritional status. Blood urea nitrogen (E) is a measure of kidney function, not a specific indicator of nutritional status. Therefore, the nurse should primarily focus on assessing the patient's serum albumin level for nutritional status evaluation in this case.

Correct Answer: B

Rationale: Interdisciplinary collaboration involves clinicians from different backgrounds integrating their separate plans of care, ensuring a holistic approach to patient care. This fosters a comprehensive understanding of the patient's needs and individualized care. In contrast, multidisciplinary practice involves clinicians working independently without integrating their plans, potentially leading to fragmented care. Choice A is incorrect as interdisciplinary collaboration does have a team leader to coordinate and facilitate communication among team members. Choice C is incorrect because while communication and cooperation are essential in interdisciplinary collaboration, the key distinction is the integration of different perspectives and plans of care. Choice D is incorrect as interdisciplinary collaboration goes beyond just medical expertise and patient preference, involving professionals from various disciplines working together to address all aspects of patient care.
