Correct Answer: A

Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.

Correct Answer: B

Rationale: The best response for the nurse is to advise the postpartum client to wait until the postpartum check-up before resuming sexual activity. This allows for complete healing to ensure the client's well-being and provides an opportunity to address any concerns with the healthcare provider. Choice A is incorrect because resuming sexual activity should be based on medical advice rather than personal readiness. Choice C is incorrect as the 6-week recommendation is a general guideline but individual circumstances may vary. Choice D is incorrect as the cessation of lochia is not the sole indicator for safe resumption of sexual activity.

Correct Answer: B

Rationale: Multivitamins are not typically considered a non-pharmacological technique for lowering blood pressure. While dietary changes, smoking cessation, and limiting caffeine intake can positively impact blood pressure levels, multivitamins are generally not specifically recommended as a primary intervention for this purpose. Dietary changes can include reducing salt intake and increasing potassium-rich foods, which are known to help manage blood pressure. Smoking cessation is crucial due to the negative impact of smoking on blood pressure and overall cardiovascular health. Limiting caffeine intake is advised as excessive caffeine consumption can lead to a temporary increase in blood pressure. Therefore, focusing on lifestyle modifications like healthy eating, smoking cessation, and caffeine reduction is more effective in managing blood pressure than relying on multivitamins.

Correct Answer: A

Rationale: The correct instruction for the client postpartum is to use ice packs to reduce swelling for the first 24 hours. This helps alleviate discomfort and promote healing. Applying heat packs immediately after birth is not recommended as they can increase swelling. A peri-bottle is advised for cleansing the perineum, not to be avoided. Tampons should not be used to absorb lochia discharge as they can increase the risk of infection. Therefore, the use of ice packs is the most appropriate and beneficial instruction for perineal care postpartum.

Correct Answer: C

Rationale: Cabbage is an example of a goitrogen that should be avoided in children with hypothyroidism. Goitrogens are substances that can interfere with thyroid function by inhibiting iodine uptake, potentially worsening the condition. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contains compounds that can affect thyroid hormone production. Oranges, tomatoes, and grapes are not classified as goitrogens. Therefore, it is important for parents to be aware of foods like cabbage and to limit their child's intake to help manage their hypothyroidism effectively.
