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. During a woman's first prenatal visit, the nurse reviews her health care record, noting a history of chickenpox as a child and syphilis as a teenager. Which action is most important for the nurse to take?

• A. Obtain blood and urine for prenatal screens.
• B. Schedule prenatal visits to occur monthly.
• C. Explain common complications of pregnancy.
• D. Obtain baseline blood pressure and weight.

Correct answer: A

Rationale: Obtaining blood and urine for prenatal screens is crucial in identifying any potential infections or conditions that may require monitoring throughout the pregnancy. Screening for infections such as syphilis is essential to ensure appropriate management and prevent adverse outcomes. This action helps in early detection and timely intervention, promoting the health and well-being of both the mother and the developing fetus. The other options, while important during prenatal care, are not as critical as obtaining prenatal screens to assess for any existing infections that could impact the pregnancy.

3. The healthcare provider is providing preconception counseling. Which supplement should the provider recommend to help prevent the occurrence of anencephaly?

• A. Folic Acid.
• B. Calcium.
• C. Iron.
• D. Vitamin D.

Correct answer: A

Rationale: Folic acid supplementation before and during early pregnancy is crucial for reducing the risk of neural tube defects, including anencephaly. Anencephaly is a severe birth defect in which a baby is born without parts of the brain and skull. Folic acid plays a key role in neural tube development and can significantly lower the chances of such defects when taken prior to conception and in early pregnancy.

4. A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks what is the purpose of the ointment. The nurse would be correct in stating that the purpose of the ointment is:

• A. Prevent eye infection.
• B. Dilate the pupil so the red reflex can be visualized.
• C. Clear the infant's vision.
• D. Prevent herpes infection.

Correct answer: A

Rationale: The correct answer is A: Prevent eye infection. Eye ointment, usually containing erythromycin, is applied to prevent neonatal conjunctivitis, which can be caused by bacteria present in the birth canal. It is not used to dilate the pupil, clear the infant's vision, or prevent herpes infection.

5. A young girl with a fractured radius has a cast applied. As the cast is drying, it is elevated above the level of her heart. Which assessment finding should the healthcare provider be reported to immediately?

• A. Itching sensation under the cast.
• B. Swelling of fingers with brisk capillary refill.
• C. Numbness and inability to move fingers.
• D. Visible bruising above the cast.

Correct answer: C

Rationale: Numbness and inability to move fingers are concerning findings that suggest potential nerve damage or compartment syndrome due to increased pressure within the cast. This requires immediate notification of the healthcare provider to prevent further complications or permanent damage.
