Nursing Elites

1. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

2. During a newborn assessment, which symptom would indicate respiratory distress if present in a newborn?

• A. Flaring of the nares.
• B. Shallow and irregular respirations.
• C. Respiratory rate of 50 breaths per minute.
• D. Abdominal breathing with synchronous chest movement.

Correct answer: A

Rationale: Flaring of the nares is a classic sign of respiratory distress in newborns. It indicates that the newborn is working hard to breathe, and immediate attention should be given to assess and address the respiratory status of the infant.

3. The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
• B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
• C. The lack of the protein dystrophin in the mother can impact the XXX muscle groups of males.
• D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.

4. A child with leukemia is admitted for chemotherapy, and the nursing diagnosis 'altered nutrition, less than body requirements related to anorexia, nausea, and vomiting' is identified. Which intervention should the nurse include in this child’s plan of care?

• A. Allow the child to eat any food desired and tolerated.
• B. Provide small, frequent meals that are high in protein and calories.
• C. Offer the child preferred foods and avoid foods that are not well-tolerated.
• D. Consult with a dietitian to provide appropriate nutritional support.

Correct answer: B

Rationale: In children with leukemia undergoing chemotherapy, anorexia, nausea, and vomiting are common issues leading to altered nutrition. Providing small, frequent meals that are high in protein and calories is essential to address these symptoms and meet the child's nutritional needs effectively. This approach helps in managing the side effects of treatment and supporting the child's nutritional requirements during this challenging time.

5. 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.
