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. 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.

3. A client whose labor is being augmented with an oxytocin (Pitocin) infusion requests an epidural for pain control. Findings of the last vaginal exam, performed 1 hour ago, were 3 cm cervical dilation, 60% effacement, and a -2 station. What action should the nurse implement first?

• A. Decrease the oxytocin infusion rate
• B. Determine current cervical dilation
• C. Request placement of the epidural
• D. Give a bolus of intravenous fluids

Correct answer: D

Rationale: In a client receiving an oxytocin infusion who requests an epidural, it is crucial to give a bolus of intravenous fluids first. This action helps prevent hypotension, a common side effect of epidural anesthesia, before the placement of the epidural. Maintaining adequate hydration is essential to support maternal blood pressure stability during the procedure.

4. When preparing a class on newborn care for expectant parents, what content should be taught concerning the newborn infant born at term gestation?

• A. Milia are white marks caused by sebaceous glands and typically resolve within 2 to 4 weeks.
• B. Meconium is the first stool and is typically dark green or black in color.
• C. Vernix caseosa is a white, cheesy substance mainly found in skin folds, providing a protective layer.
• D. Pseudostrabismus in newborns usually self-resolves without the need for intervention.

Correct answer: C

Rationale: Vernix caseosa is a white, cheesy substance that acts as a protective barrier on the skin of newborns, particularly present in skin folds. It helps to prevent dehydration and protect the delicate skin of the newborn from the amniotic fluid in utero. Educating expectant parents about the presence and function of vernix caseosa can help them understand the importance of its preservation during the immediate postnatal period. Choices A, B, and D are incorrect as they do not directly relate to the protective function of vernix caseosa in newborns. Milia are small, white bumps on the skin due to blocked oil glands, meconium is the first stool of a newborn and is typically dark green or black in color, and pseudostrabismus refers to false appearance of misalignment of the eyes, which usually resolves on its own without intervention.

5. When assessing a client who is at 12-weeks gestation, the LPN/LVN recommends that she and her husband consider attending childbirth preparation classes. When is the best time for the couple to attend these classes?

• A. At 16 weeks gestation.
• B. At 20 weeks gestation.
• C. At 24 weeks gestation.
• D. At 30 weeks gestation.

Correct answer: D

Rationale: The best time for the couple to attend childbirth preparation classes is around 30 weeks gestation, which is during the third trimester. Attending classes at this time allows the couple to learn essential information and skills as labor and delivery are approaching, maximizing the benefit of the classes. Option A is too early in the second trimester, and the couple might forget important details by the time labor approaches. Option B is also early in the second trimester, and attending later allows for better preparation. Option C is still in the second trimester, and waiting until the third trimester provides more practical knowledge closer to delivery.
