Correct Answer: A

Rationale: The correct treatment for chlamydia is a one-time dose of azithromycin. It is crucial for the client to understand the correct medication regimen for effective treatment. Choice B is incorrect because treatment is necessary for the partner even if asymptomatic. Choice C is incorrect because sexual relations should be avoided until treatment is completed. Choice D is incorrect as retesting should generally occur 3 months after treatment.

Correct Answer: B

Rationale: Terbutaline is a tocolytic medication that works by relaxing the uterine muscles, leading to weakened uterine contractions. This effect helps to prevent preterm labor. Therefore, the nurse should expect weakened uterine contractions in a client who has received terbutaline at 28 weeks of gestation. Choices A, C, and D are incorrect. Terbutaline administration would not directly affect the fetal heart rate, enhance fetal lung surfactant production, or cause maternal hypoglycemia.

Correct Answer: A

Rationale: During pregnancy, gradual lordosis is a common adaptation to the growing fetus. Lordosis refers to an increased lumbar curve in the spine, which helps to shift the center of gravity forward, supporting the enlarging uterus. This change is necessary to maintain balance and reduce strain on the back muscles as the pregnancy progresses. Increased abdominal muscle tone, posterior neck flexion, and decreased mobility of pelvic joints are not typical physiological changes during pregnancy. Increased abdominal muscle tone is not expected as the abdominal muscles tend to stretch and separate to accommodate the growing fetus. Posterior neck flexion is not a common finding and decreased mobility of pelvic joints is not an expected change and can cause discomfort.

Correct Answer: D

Rationale: The correct action to check for the Moro reflex in a newborn is to hold the newborn in a semi-sitting position and then allow the newborn's head and trunk to fall backward. The Moro reflex is elicited by a sudden loss of support or a loud noise. The normal response involves symmetrical abduction and extension of the arms, followed by their return to the midline in an embracing motion. Choices A, B, and C do not describe the correct method for assessing the Moro reflex and are therefore incorrect.

Correct Answer: C

Rationale: The correct technique for bottle feeding includes keeping the nipple full of formula throughout the feeding to prevent air from entering the baby's stomach. This helps reduce the risk of the baby swallowing air, which can lead to discomfort and colic. Therefore, maintaining a full nipple during feeding is essential for the baby's comfort and digestion. Option A is incorrect as burping should be done during the feeding to prevent excessive air intake. Option B is incorrect as the baby should be held semi-upright, not in a supine position, to reduce the risk of choking and ear infections. Option D is irrelevant to the feeding process and does not contribute to the baby's well-being.
