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 client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

3. A pregnant client receives Rho(D) immune globulin after an amniocentesis. The day following, she reports a temperature of 99.8°F (37.67°C). Which action should the nurse implement?

• A. Schedule a visit with the healthcare provider today.
• B. Verify the compatibility of the administered Rho(D) immune globulin.
• C. Encourage the client to increase her intake of oral fluids.
• D. Instruct the client to maintain bedrest for 24 hours.

Correct answer: C

Rationale: A mild increase in temperature post-amniocentesis is common, and encouraging the client to increase oral fluid intake is the appropriate action. Increasing fluid intake can help reduce mild fever, promote recovery, and prevent dehydration. It is important for the nurse to educate the client on the importance of staying hydrated to support her overall well-being during this time.

4. The LPN/LVN should explain to a 30-year-old gravida client that alpha fetoprotein testing is recommended for which purpose?

• A. Detect cardiovascular disorders.
• B. Screen for neural tube defects.
• C. Monitor placental functioning.
• D. Assess for maternal pre-eclampsia.

Correct answer: B

Rationale: The correct answer is B: Screen for neural tube defects. Alpha fetoprotein testing is primarily used to screen for neural tube defects and other fetal abnormalities. It is not used to detect cardiovascular disorders, monitor placental functioning, or assess for maternal pre-eclampsia.

5. The LPN/LVN is counseling a woman who wants to become pregnant. The woman tells the nurse that she has a 36-day menstrual cycle and the first day of her last menstrual period was January 8. The nurse calculates that the woman's next fertile period is

• A. January 14-15.
• B. January 22-23.
• C. January 30-31.
• D. February 6-7.

Correct answer: C

Rationale: To determine the fertile period, subtract 14 days from the length of the woman's menstrual cycle. In this case, 36-14 = 22. Counting forward from the first day of the last menstrual period (January 8), the fertile period falls around January 30-31. This is because ovulation typically occurs approximately 14 days before the start of the next menstrual period, marking the fertile window for conception.
