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. 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.

3. Albumin 25% IV is prescribed for a child with nephrotic syndrome. Which assessment finding indicates to the nurse that the medication is having the desired effect?

• A. Weight gain.
• B. Reduction of fever.
• C. Improved caloric intake.
• D. Reduction of edema.

Correct answer: D

Rationale: The correct answer is D: Reduction of edema. Albumin helps reduce edema by increasing oncotic pressure, drawing fluid back into the blood vessels. In nephrotic syndrome, there is an abnormal loss of protein in the urine, leading to decreased oncotic pressure and fluid shifting into the interstitial spaces, causing edema. Administering albumin helps restore the oncotic pressure, reducing edema, which is a desirable effect of the medication.

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. The nurse is conducting postpartum teaching with a mother who is breastfeeding her infant. When discussing birth control which method should the nurse recommend to this client as best for her to use in preventing unwanted pregnancy?

• A. Breastfeed exclusively at least every 3 to 4 hours.
• B. Condoms and contraceptive foam or gel.
• C. Rhythm method (natural family planning).
• D. Combined estrogen-progesterone oral contraceptives.

Correct answer: B

Rationale: Condoms and contraceptive foam or gel are safe options for breastfeeding mothers and do not affect milk supply.
