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. Immediately after birth, a newborn infant is suctioned, dried, and placed under a radiant warmer. The infant has spontaneous respirations, and the nurse assesses an apical heart rate of 80 beats/minute and respirations of 20 breaths/minute. What action should the nurse take next?

• A. Initiate positive pressure ventilation.
• B. Intervene after the one-minute Apgar assessment.
• C. Initiate CPR on the infant.
• D. Assess the infant's blood glucose level.

Correct answer: A

Rationale: A heart rate below 100 bpm in a newborn indicates bradycardia and requires intervention. Positive pressure ventilation should be initiated to improve oxygenation and help increase the infant's heart rate. This intervention is crucial to support the newborn's transition to extrauterine life and prevent further complications.

3. During the newborn admission assessment, the nurse palpates the newborn's scrotum and does not feel the testicles. Which assessment technique should the nurse perform next to verify the absence of testes?

• A. Observe the urethral opening on the surface of the penis when the newborn voids.
• B. Perform transillumination of the scrotal sac to visualize shadows of the testes.
• C. Use a fingertip to palpate the inguinal canal for a retractile or undescended testis.
• D. Measure the size of the scrotal sac for length and width.

Correct answer: C

Rationale: If the testes are not palpated in the scrotum, the next step is to check the inguinal canal for a retractile or undescended testis. This technique allows the nurse to determine if the testes are located within the inguinal canal rather than the scrotum. It is essential to assess for the presence of testes in the inguinal canal to ensure proper diagnosis and management of any potential issues related to testicular positioning.

4. A multiparous client with active herpes lesions is admitted to the unit with spontaneous rupture of membranes. Which action should the nurse take?

• A. Obtain blood culture.
• B. Administer penicillin.
• C. Cover lesion with a dressing.
• D. Prepare her for cesarean section.

Correct answer: D

Rationale: Active herpes lesions at the time of delivery increase the risk of neonatal transmission. The most appropriate action in this scenario is to prepare the client for a cesarean section. A cesarean section is often recommended to reduce the risk of neonatal transmission of herpes simplex virus during delivery, especially when active lesions are present. This intervention helps minimize direct contact between the newborn and the infected genital tract secretions, thereby decreasing the risk of transmission.

5. What advice is most important for a client in the first trimester of pregnancy experiencing nausea?

• A. Practice relaxation techniques when nausea begins.
• B. Increase fluid intake to 3 quarts daily.
• C. Avoid alcohol, caffeine, and smoking.
• D. Eliminate snacks between meals.

Correct answer: C

Rationale: During the first trimester of pregnancy, it is crucial to advise pregnant clients to avoid alcohol, caffeine, and smoking. These substances can worsen nausea and harm fetal development. By eliminating these substances, the client can help alleviate nausea and create a healthier environment for the developing fetus. Choices A, B, and D are not as critical in managing nausea during the first trimester. While relaxation techniques may help, avoiding harmful substances like alcohol, caffeine, and smoking takes precedence. Increasing fluid intake can be beneficial but not as crucial as avoiding harmful substances. Eliminating snacks between meals may not be necessary for all clients and is not directly related to managing nausea in the first trimester.
