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. In assessing a 9-year-old boy admitted to the hospital with possible acute post-streptococcal glomerulonephritis (APSGN), what information is most significant to obtain in his history?

• A. Back pain for a few days
• B. A history of hypertension
• C. A sore throat last week
• D. Diuresis during the nights

Correct answer: C

Rationale: A recent sore throat is most significant in this case as it could indicate a preceding streptococcal infection, which is a crucial factor in diagnosing APSGN. Streptococcal infection often precedes APSGN, and recognizing this history is essential for appropriate management and treatment. Choices A, B, and D are less relevant in the context of APSGN. Back pain and diuresis are symptoms that may not directly correlate with APSGN, while a history of hypertension, although important in general health assessment, is not as specific to the current scenario compared to a recent sore throat.

3. A 26-year-old, gravida 2, para 1 client is admitted to the hospital at 28 weeks gestation in preterm labor. She is given 3 doses of terbutaline sulfate (Brethine) 0.25 mg subcutaneously to stop her labor contractions. The LPN/LVN plans to monitor for which primary side effect of terbutaline sulfate?

• A. Drowsiness and bradycardia.
• B. Depressed reflexes and increased respirations.
• C. Tachycardia and a feeling of nervousness.
• D. A flushed, warm feeling and a dry mouth.

Correct answer: C

Rationale: The primary side effects of terbutaline sulfate are related to its beta-adrenergic effects. Tachycardia and nervousness are common side effects of terbutaline sulfate. Tachycardia is expected due to the drug's beta-agonist properties, while nervousness can result from the stimulation of beta-adrenergic receptors. It is crucial to monitor the client for these side effects to ensure early recognition and appropriate management.

4. To confirm respiratory distress syndrome (RDS) in a newborn, what should the nurse assess?

• A. Assess diaphragmatic breathing.
• B. Assess heart sounds.
• C. Monitor blood oxygen levels.
• D. Check for signs of infection.

Correct answer: A

Rationale: To confirm respiratory distress syndrome (RDS) in a newborn, the nurse should assess diaphragmatic breathing. In RDS, the baby may have difficulty breathing due to immature lungs, leading to shallow, rapid breathing movements. Assessing diaphragmatic breathing directly evaluates the respiratory effort and can help identify the presence of RDS. Choice B, assessing heart sounds, is not specific to diagnosing RDS but could be relevant for other conditions. Choice C, monitoring blood oxygen levels, is important but alone may not confirm RDS. Choice D, checking for signs of infection, is not a direct indicator of RDS but rather suggests a different issue.

5. A 28-year-old client in active labor complains of cramps in her leg. What intervention should be implemented?

• A. Massage the calf and foot.
• B. Extend the leg and dorsiflex the foot.
• C. Lower the leg off the side of the bed.
• D. Elevate the leg above the heart.

Correct answer: B

Rationale: During active labor, if a client complains of leg cramps, extending the leg and dorsiflexing the foot can help relieve the muscle cramps by stretching the affected muscles. This intervention promotes circulation and can alleviate discomfort associated with leg cramps.
