During the third trimester of pregnancy, which of the following findings should a nurse recognize as an expected physiologic change?

Correct Answer: A

Rationale: The correct answer is A: Gradual lordosis. During the third trimester, the growing uterus shifts the center of gravity forward, leading to an increased lumbar curvature known as lordosis. This change helps maintain balance and support the extra weight. Increased abdominal muscle tone (B) is not an expected finding as abdominal muscles tend to stretch and weaken during pregnancy. Posterior neck flexion (C) is not a common physiologic change during the third trimester. Decreased mobility of pelvic joints (D) is incorrect as hormonal changes during pregnancy actually increase flexibility in the pelvic joints to prepare for childbirth.

Correct Answer: C

Rationale: Rationale: - MSAFP screening is recommended for all pregnant clients to assess risk of neural tube defects or chromosomal abnormalities. - It is a standard prenatal test regardless of specific medical conditions. - Options A, B, and D are not directly related to the indication for MSAFP screening in pregnancy.

Correct Answer: A

Rationale: The correct answer is A because chlamydia is commonly treated with a single dose of azithromycin to ensure complete eradication of the infection. This antibiotic is highly effective against chlamydia. Option B is incorrect because both partners need treatment regardless of symptoms. Option C is incorrect as sexual abstinence for 7 days is recommended post-treatment. Option D is incorrect as retesting should be done after 3 months, not 6 months.

Correct Answer: C

Rationale: The correct answer is C. Tilt the bottle to prevent air from entering as the baby sucks is incorrect. It is important not to tilt the bottle as it can cause the baby to swallow air, leading to gas and discomfort. A: Keeping the baby's head elevated helps prevent choking. B: Allowing the baby to burp reduces gas and discomfort. D: Soft, formed yellow stools indicate a healthy digestive system. Thus, C is the only statement that may lead to issues and requires further instruction.

Correct Answer: D

Rationale: The correct answer is D: Wide skull sutures. Small for gestational age (SGA) newborns may have wide skull sutures due to reduced skull growth in utero. This is because their growth was restricted, leading to smaller head size and delayed closure of skull sutures. A, B, and C are incorrect: A: Moist skin is not a typical finding associated with being small for gestational age. B: Protruding abdomen is more commonly seen in conditions like gastroschisis or omphalocele, not necessarily SGA. C: Gray umbilical cord color is not specifically linked to being small for gestational age.
