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. 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.

3. What action should the nurse take if an infant, who was born yesterday weighing 7.5 lbs (3,402 grams), weighs 7 lbs (3,175 grams) today?

• A. Inform and assure the mother that this is normal weight loss.
• B. Encourage the mother to increase the frequency of breastfeeding.
• C. After verifying the accuracy of weight, notify the healthcare provider.
• D. Monitor the stool and urine output of the neonate for the last 24 hours.

Correct answer: A

Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.

4. The healthcare provider is reviewing the serum laboratory findings for a 5-day-old infant with congenital adrenal hyperplasia. Which laboratory result should be reported to the healthcare provider immediately?

• A. Bilirubin of 1.5 mg/dl.
• B. Glucose of 80 mg/dl.
• C. Potassium of 4.5 mEq/L.
• D. Sodium of 119 mEq/L.

Correct answer: D

Rationale: Low sodium levels in congenital adrenal hyperplasia can indicate salt-wasting crisis, which is a life-threatening emergency requiring immediate medical attention. Monitoring sodium levels is crucial to prevent complications such as dehydration and shock in these patients.

5. What should the nurse recommend to a woman with mastitis?

• A. Apply heat to the affected area.
• B. Apply cold compresses to the affected area.
• C. Use a breast pump to express milk.
• D. Continue breastfeeding as usual.

Correct answer: A

Rationale: The nurse should recommend applying heat to the affected area for a woman with mastitis. Heat can help reduce pain and inflammation associated with mastitis by improving blood flow to the area and promoting healing.
