Nursing Elites

1. 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?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

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.

2. Insulin therapy is initiated for a 12-year-old child who is admitted with diabetic ketoacidosis (DKA). Which action is most important for the nurse to include in the child’s plan of care?

• A. Monitor serum glucose for adjustment in the infusion rate of regular insulin (Novolin R).
• B. Determine the child’s compliance schedule for subcutaneous NPH insulin (Humulin N).
• C. Demonstrate to the parents how to program an insulin pen for daily glucose regulation.
• D. Consult with the healthcare provider about the use of insulin detemir (Levemir Flex Pen).

Correct answer: A

Rationale: In managing diabetic ketoacidosis (DKA), monitoring serum glucose levels is crucial to adjust the infusion rate of regular insulin effectively. This helps in controlling blood glucose levels and preventing complications associated with DKA. Close monitoring and adjustments based on glucose levels are essential for the successful management of DKA. Choice B is incorrect as it focuses on a different type of insulin and compliance schedule without addressing the immediate needs of managing DKA. Choice C is not the priority action and involves educating parents on a different method of insulin administration. Choice D is also not the most important action as it suggests consulting with the healthcare provider about a different type of insulin rather than focusing on immediate glucose monitoring for insulin adjustment in DKA management.

3. Which intervention is most helpful in relieving postpartum uterine contractions or 'afterpains'?

• A. Lying prone with a pillow on the abdomen.
• B. Using a breast pump.
• C. Massaging the abdomen.
• D. Giving oxytocic medications.

Correct answer: A

Rationale: Lying prone with a pillow on the abdomen is the most helpful intervention in relieving postpartum uterine contractions or 'afterpains.' This position provides counter-pressure and support to the uterus, helping to alleviate discomfort and promote uterine involution. Choice B, using a breast pump, is not effective in relieving afterpains as it focuses on milk expression. Massaging the abdomen (Choice C) may help with discomfort but does not provide the same level of support as lying prone with a pillow. Giving oxytocic medications (Choice D) is not typically the first-line intervention for afterpains unless there are specific medical indications.

4. The nurse is measuring the frontal occipital circumference (FOC) of a 3-month-old infant, notes that the FOC has increased by 5 cm since birth, and observes that the child’s head appears large in relation to body size. Which action is most important for the nurse to take next?

• A. Measure the infant’s head-to-heel length
• B. Observe the infant for sunsetting eyes
• C. Palpate the anterior fontanel for tension and bulging
• D. Plot the measurement on the infant’s growth chart

Correct answer: C

Rationale: Palpating the anterior fontanel for tension and bulging is essential to assess for increased intracranial pressure, which could be indicated by the enlarged head circumference. This assessment can help identify potential neurological issues that need prompt attention.

5. While caring for a laboring client on continuous fetal monitoring, the nurse notes a fetal heart rate pattern that falls and rises abruptly with a 'V' shaped appearance. What action should the nurse take first?

• A. Change the maternal position.
• B. Administer oxygen at 10 L by mask.
• C. Prepare for a potential cesarean.
• D. Allow the client to begin pushing.

Correct answer: A

Rationale: In cases of fetal heart rate patterns showing abrupt falls and rises with a 'V' shaped appearance, it indicates possible cord compression. Changing the maternal position, such as moving the mother onto her side, can relieve the pressure off the cord and help improve fetal oxygenation, making it the priority intervention to address the decelerations.
