Nursing Elites

1. A client at 32 weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved?

• A. 4+ reflexes
• B. Urinary output of 50 ml per hour
• C. A decrease in respiratory rate from 24 to 16
• D. A decreased body temperature

Correct answer: C

Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.

2. 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.

3. In developing a teaching plan for expectant parents, the nurse plans to include information about when the parents can expect the infant's fontanels to close. The LPN/LVN bases the explanation on knowledge that for the normal newborn, the

• A. anterior fontanel closes at 2 to 4 months and the posterior by the end of the first week.
• B. anterior fontanel closes at 5 to 7 months and the posterior by the end of the second week.
• C. anterior fontanel closes at 8 to 11 months and the posterior by the end of the first month.
• D. anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month.

Correct answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.

4. After breastfeeding for 10 minutes at each breast, a new mother calls the nurse to the postpartum room to help change the newborn's diaper. As the mother begins the diaper change, the newborn spits up the breast milk. What action should the nurse implement first?

• A. Wipe away the spit-up and assist the mother with the diaper change.
• B. Sit the newborn upright and burp by rubbing or patting the upper back.
• C. Place the newborn in a position with the head lower than the feet.
• D. Turn the newborn to the side and use bulb suction for the mouth and nares.

Correct answer: B

Rationale: After a newborn spits up breast milk following feeding, the priority action for the nurse is to sit the newborn upright and burp by rubbing or patting the upper back. This position helps release trapped air and reduces the likelihood of further spit-up or aspiration. It is essential to address this first to prevent potential complications and ensure the newborn's comfort and safety.

5. After administering the varicella vaccine to a 5-year-old child, which instruction should the nurse provide the child’s parent?

• A. Chewable children’s aspirin will not help prevent inflammation.
• B. Keep the child home for the next two days.
• C. Any fever should be monitored and reported if severe.
• D. Apply a cool pack to the injection site to reduce discomfort.

Correct answer: D

Rationale: After receiving the varicella vaccine, applying a cool pack to the injection site can help reduce discomfort. This intervention is a simple and effective way to manage local reactions at the site of the vaccination, providing comfort to the child and potentially reducing swelling or pain. Choices A, B, and C are incorrect because chewable children’s aspirin is not typically recommended after vaccination, keeping the child home is not necessary unless advised by a healthcare provider, and monitoring fever alone is not the primary instruction post-varicella vaccination.
