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 28 weeks gestation calls the antepartum clinic and reports experiencing a small amount of bright red vaginal bleeding without uterine contractions or abdominal pain. What instruction should the LPN/LVN provide?

• A. Come to the clinic today for an ultrasound.
• B. Go immediately to the emergency room.
• C. Lie on your left side for about one hour and see if the bleeding stops.
• D. Bring a urine specimen to the lab tomorrow to determine if you have a urinary tract infection.

Correct answer: A

Rationale: Bright red vaginal bleeding without pain could indicate placental issues such as previa. An ultrasound is necessary to evaluate the cause. It is important to rule out potential serious conditions like placental previa, which can lead to further complications for both the mother and the fetus. Therefore, prompt evaluation through an ultrasound at the clinic is essential for appropriate management and ensuring the well-being of the client and her baby.

3. Why is complete bedrest necessary for a pregnant client with mitral stenosis Class III?

• A. Complete bedrest decreases oxygen needs and demands on the heart muscle tissue.
• B. We want your baby to be healthy, and this is the only way we can ensure that will happen.
• C. I know you're upset. Would you like to talk about some activities you could do while in bed?
• D. Labor is difficult, and you need to use this time to rest before assuming child-caring duties.

Correct answer: A

Rationale: Complete bedrest is necessary for a pregnant client with mitral stenosis Class III to reduce the workload on the heart, lower oxygen consumption, and prevent complications associated with cardiac conditions like mitral stenosis. By remaining in bed, the client can help maintain cardiac function and promote a safer pregnancy outcome. Choice B is incorrect as it does not provide a specific reason related to the client's medical condition. Choice C is not addressing the medical necessity of bedrest for this particular client. Choice D is irrelevant and does not explain the importance of bedrest for a pregnant client with mitral stenosis Class III.

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. 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.
