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. 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.

3. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?

• A. Muscle tension decreases with fine motor skill projects, so these activities should be encouraged.
• B. The chorea or movements are temporary and will eventually disappear.
• C. Permanent lifestyle changes are not needed to promote safety in the home.
• D. Consistent discipline is not directly related to controlling the movements.

Correct answer: B

Rationale: Chorea, or sudden aimless movements associated with rheumatic fever, is temporary in nature and will eventually disappear on its own. It is important for the nurse to reassure the parents that these movements are part of the condition and typically resolve over time without the need for permanent lifestyle changes or strict discipline. Providing accurate information and reassurance to the parents can help alleviate concerns and promote understanding of the condition's course. Choices A, C, and D are incorrect because muscle tension, permanent lifestyle changes, and consistent discipline are not directly related to the resolution of chorea in rheumatic fever.

4. What is the best nursing intervention for a pregnant woman with hyperemesis gravidarum?

• A. Administer prescribed IV solution.
• B. Give oral rehydration solution.
• C. Encourage small, frequent meals.
• D. Offer ginger tea to reduce nausea.

Correct answer: A

Rationale: The best nursing intervention for a pregnant woman with hyperemesis gravidarum is to administer the prescribed IV solution. Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. Administering IV fluids helps in managing dehydration, replenishing electrolytes, and providing the necessary hydration for both the mother and the fetus. Giving oral rehydration solution (Choice B) may not be sufficient for severe cases of hyperemesis gravidarum where IV fluids are required. Encouraging small, frequent meals (Choice C) may not be effective as the woman may not be able to tolerate oral intake. Offering ginger tea (Choice D) is not the most appropriate intervention for hyperemesis gravidarum, as it may not provide adequate hydration or electrolyte balance needed in severe cases.

5. A client at 32-weeks gestation comes to the prenatal clinic with complaints of pedal edema, dyspnea, fatigue, and a moist cough. Which question is most important for the LPN/LVN to ask this client?

• A. Which symptom did you experience first?
• B. Are you consuming large amounts of salty foods?
• C. Have you traveled to a foreign country recently?
• D. Do you have a history of rheumatic fever?

Correct answer: D

Rationale: The correct answer is D. Rheumatic fever can lead to rheumatic heart disease, which may be exacerbated during pregnancy, causing symptoms like pedal edema and dyspnea. Asking about a history of rheumatic fever is crucial in this case to assess the potential impact on the client's current symptoms. Choices A, B, and C are less relevant in this scenario as they do not directly relate to the presenting symptoms and history of rheumatic fever.
