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. At 14-weeks gestation, a client arrives at the Emergency Center complaining of a dull pain in the right lower quadrant of her abdomen. The LPN/LVN obtains a blood sample and initiates an IV. Thirty minutes after admission, the client reports feeling a sharp abdominal pain and shoulder pain. Assessment findings include diaphoresis, a heart rate of 120 beats/minute, and a blood pressure of 86/48. Which action should the nurse implement next?

• A. Check the hematocrit results.
• B. Administer pain medication.
• C. Increase the rate of IV fluids.
• D. Monitor the client for contractions.

Correct answer: C

Rationale: The client's symptoms suggest hypovolemic shock, possibly due to an ectopic pregnancy. Increasing IV fluids is crucial to stabilize the client by improving blood pressure and perfusion. This intervention helps address the underlying issue of hypovolemia and supports the client's hemodynamic status, which takes priority in this emergent situation.

4. What is the most important assessment for the healthcare provider to conduct following the administration of epidural anesthesia to a client who is at 40-weeks gestation?

• A. Maternal blood pressure.
• B. Level of pain sensation
• C. Station of presenting part.
• D. Variability of fetal heart rate.

Correct answer: A

Rationale: Following the administration of epidural anesthesia, the most crucial assessment for the healthcare provider to conduct is monitoring maternal blood pressure. Epidural anesthesia can lead to hypotension as a common side effect, which can have significant implications for both the mother and the fetus. Therefore, close monitoring of maternal blood pressure is essential to detect and manage any hypotensive episodes promptly. Choices B, C, and D are important assessments during labor and delivery, but in this specific scenario of post-epidural anesthesia, monitoring maternal blood pressure takes precedence due to the potential risk of hypotension.

5. The nurse is caring for a one-year-old child following surgical correction of hypospadias. Which nursing action has the highest priority?

• A. Monitor urinary output
• B. Auscultate bowel sounds
• C. Observe appearance of stool
• D. Record percent of diet consumed

Correct answer: A

Rationale: In caring for a one-year-old child post hypospadias surgery, the highest priority action is to monitor urinary output. This is crucial to assess kidney function and ensure there are no complications following the surgical procedure. Auscultating bowel sounds, observing stool appearance, and recording diet consumption are important assessments too, but in this case, monitoring urinary output takes precedence due to the nature of the surgery and potential complications related to urinary function.
