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 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.

3. A postpartum client who is Rh-negative refuses to receive RhoGAM after the delivery of an infant who is Rh-positive. Which information should the nurse provide this client?

• A. RhoGAM prevents maternal antibody formation for future Rh-positive babies.
• B. RhoGAM is not necessary unless all of her pregnancies are Rh-positive.
• C. The Rh-positive factor from the fetus threatens her blood cells.
• D. The mother should receive RhoGAM when the baby is Rh-negative.

Correct answer: A

Rationale: The correct answer is A. RhoGAM is administered to Rh-negative individuals after exposure to Rh-positive blood to prevent the development of antibodies that could harm future Rh-positive babies during subsequent pregnancies. By refusing RhoGAM after the delivery of an Rh-positive infant, the mother risks developing these antibodies, which could lead to hemolytic disease in future pregnancies with Rh-positive babies. Therefore, it is crucial for the nurse to explain to the client that receiving RhoGAM prevents the formation of maternal antibodies against Rh-positive blood, safeguarding the health of future babies. Choices B, C, and D are incorrect. Choice B is incorrect because RhoGAM is necessary after exposure to Rh-positive blood, regardless of the Rh status of future pregnancies. Choice C is incorrect as it does not accurately convey the purpose of RhoGAM administration. Choice D is incorrect because RhoGAM is specifically given after exposure to Rh-positive blood, not when the baby is Rh-negative.

4. A child with ADHD needs help with homework. What should the nurse encourage the parents to do?

• A. Encourage the parents to help the child with homework.
• B. Do the homework for the child.
• C. Set a regular homework schedule.
• D. Provide a quiet environment for homework.

Correct answer: A

Rationale: Encouraging parents to help the child with homework is the most appropriate course of action. By assisting the child, parents can provide necessary support and guidance without taking over the task entirely. This approach fosters independence and helps the child develop academic skills. Option B, doing the homework for the child, is counterproductive as it does not empower the child to learn and grow independently. Option C, setting a regular homework schedule, is important but does not address the immediate need for assistance. Option D, providing a quiet environment for homework, is helpful but does not directly involve parents in supporting the child's academic progress.

5. The client is 24 hours postpartum and is being discharged. The nurse explains that vaginal discharge will change from red to pink and then to white. If the client starts having red bleeding after the color changes, what should the nurse instruct the client to do?

• A. Reduce activity level and notify the healthcare provider.
• B. Go to bed and assume a knee-chest position.
• C. Massage the uterus and go to the emergency room.
• D. Do not worry as this is a normal occurrence.

Correct answer: A

Rationale: If the client experiences red bleeding after the color changes, it may indicate possible hemorrhage or retained placental fragments, which require immediate attention. Instructing the client to reduce activity level and notify the healthcare provider is crucial for prompt evaluation and management of potential complications.
