A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

Correct Answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.

Correct Answer: A

Rationale: Corrected Rationale: Immediately after birth, newborns are at high risk for heat loss, which can lead to cold stress and associated complications. Maintaining thermal regulation is crucial to prevent hypothermia and ensure the newborn's survival. By addressing heat loss as a priority issue, the healthcare provider can help stabilize the newborn's temperature and support overall well-being. Choices B, C, and D are not the priority issues immediately after birth. While fluid balance, bleeding tendencies, and hypoglycemia are important considerations in newborn care, heat loss is the primary concern right after delivery to prevent complications related to thermal regulation.

Correct Answer: A

Rationale: Following the administration of epidural anesthesia, the most crucial assessment for the healthcare provider to conduct is monitoring maternal blood pressure. Epidural anesthesia can lead to hypotension as a common side effect, which can have significant implications for both the mother and the fetus. Therefore, close monitoring of maternal blood pressure is essential to detect and manage any hypotensive episodes promptly. Choices B, C, and D are important assessments during labor and delivery, but in this specific scenario of post-epidural anesthesia, monitoring maternal blood pressure takes precedence due to the potential risk of hypotension.

Correct Answer: C

Rationale: Monitoring for bleeding from IV sites is the priority intervention in this situation. The dark red vaginal bleeding, uterine tension, and other assessment findings suggest a potential placental abruption. Monitoring bleeding from IV sites can help detect coagulopathy, which may be associated with placental abruption. Options A, B, and D are not the most appropriate interventions in this scenario. Inserting an internal fetal monitor, assessing for cervical changes, and performing Leopold's maneuvers are not the priority actions when dark red vaginal bleeding and uterine tension are present, indicating a potential emergency situation.

Correct Answer: B

Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.

Correct Answer: A

Rationale: The correct answer is A: Gestational diabetes. Terbutaline (Brethine) is known to cause hyperglycemia, so it is crucial to assess for gestational diabetes before administering it. Assessing for elevated blood pressure (choice B), urinary tract infection (choice C), or swelling in lower extremities (choice D) is not directly related to the potential side effect of terbutaline in causing hyperglycemia.

Correct Answer: D

Rationale: The priority nursing intervention in this situation is to ask the client if she has experienced any recent changes in vaginal discharge. Changes in vaginal discharge can indicate preterm labor, making it crucial to assess promptly. This information will help determine if the client needs immediate medical attention and appropriate interventions to prevent preterm birth and ensure the well-being of the mother and the baby. Option A is not the priority as back pain alone does not warrant immediate ambulance transport. Option B is less relevant in this context as the focus should be on immediate concerns related to pregnancy. Option C is not the priority as addressing back pain should come after ruling out urgent pregnancy-related issues.

Correct Answer: C

Rationale: Birds are not recommended as pets for a primipara patient due to potential health risks associated with bird droppings, feathers, and dander. These factors may pose a risk to the newborn's health and the mother's well-being. Additionally, some birds can be loud, which may disrupt the baby's sleep patterns. Therefore, it is advisable for primipara patients to consider pets like dogs, cats, or fish as they generally have lower associated risks in a household with a newborn. Dogs, cats, and fish are relatively safer options compared to birds for primipara patients due to their lower risk of transmitting infections, allergens, or causing disturbances that could affect the newborn or the mother.

Correct Answer: B

Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.
