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. Upon arrival in the nursery, a newborn infant is breathing satisfactorily but appears dusky. What action should the LPN/LVN take first?

• A. Notify the healthcare provider immediately.
• B. Suction the infant's nares, then the oral cavity.
• C. Check the infant's oxygen saturation rate.
• D. Position the infant on the right side.

Correct answer: C

Rationale: The priority action in this scenario is to check the infant's oxygen saturation rate. This will provide crucial information on the infant's oxygen levels and the need for immediate oxygen therapy. Assessing oxygen saturation is essential in determining the severity of hypoxia and guiding further interventions to ensure adequate oxygenation. Option A is not the priority as immediate intervention related to oxygenation is needed before notifying the healthcare provider. Suctioning (Option B) may be necessary but should come after assessing oxygen saturation. Positioning the infant (Option D) does not address the immediate need to evaluate oxygen levels.

3. During an examination for possible cryptorchidism in an infant, what technique should be used?

• A. Place the infant in a warm room and use a calm approach.
• B. Hold the scrotum and palpate gently.
• C. Cleanse the penis with an antiseptic-soaked pad.
• D. Position the infant in a warm room to prevent muscle contraction.

Correct answer: D

Rationale: When examining an infant for cryptorchidism, it is important to position the infant in a warm room to prevent muscle contraction, which could cause the testes to retract. Placing the infant in a side-lying position may not be necessary for this specific examination. Holding the penis or retracting the foreskin is not relevant to the assessment for cryptorchidism. Cleansing the penis with an antiseptic pad is not indicated for this examination.

4. The LPN/LVN assesses a client admitted to the labor and delivery unit and obtains the following data: dark red vaginal bleeding, uterus slightly tense between contractions, BP 110/68, FHR 110 beats/minute, cervix 1 cm dilated and uneffaced. Based on these assessment findings, what intervention should the nurse implement?

• A. Insert an internal fetal monitor.
• B. Assess for cervical changes q1h.
• C. Monitor bleeding from IV sites.
• D. Perform Leopold's maneuvers.

Correct answer: C

Rationale: Monitoring for bleeding from IV sites is the priority intervention in this situation. The dark red vaginal bleeding, uterine tension, and other assessment findings suggest a potential placental abruption. Monitoring bleeding from IV sites can help detect coagulopathy, which may be associated with placental abruption. Options A, B, and D are not the most appropriate interventions in this scenario. Inserting an internal fetal monitor, assessing for cervical changes, and performing Leopold's maneuvers are not the priority actions when dark red vaginal bleeding and uterine tension are present, indicating a potential emergency situation.

5. An unlicensed assistive personnel (UAP) reports to the charge nurse that a client who delivered a 7-pound infant 12 hours ago is reporting a severe headache. The client’s blood pressure is 110/70 mmHg, respiratory rate is 18 breaths/min, heart rate is 74 beats/min, and temperature is 98.6°F (37°C). What action should the charge nurse implement first?

• A. Notify the healthcare provider of the assessment findings.
• B. Administer analgesics as prescribed.
• C. Increase the client’s fluid intake.
• D. Monitor the client’s vital signs every hour.

Correct answer: A

Rationale: A severe headache post-delivery could indicate a serious condition such as preeclampsia or a spinal headache, which requires immediate medical attention. Notifying the healthcare provider of the assessment findings allows for prompt evaluation and appropriate management of the client's condition.
