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 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.

3. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

4. When teaching a gravid client how to perform kick (fetal movement) counts, which instruction should the nurse include?

• A. If 10 kicks are not felt within one hour, drink orange juice and count for another hour.
• B. Count the movements once daily, for one hour, before breakfast.
• C. Avoid caffeinated drinks for 24 hours before conducting the kick test.
• D. Exercise for 15 minutes before starting the counting to help increase fetal movement.

Correct answer: A

Rationale: When teaching a gravid client about kick (fetal movement) counts, the nurse should instruct them that if 10 kicks are not felt within one hour, they should drink orange juice and continue counting for another hour. This instruction is crucial as a drop in fetal movements could indicate potential issues with fetal well-being, and taking action such as rechecking after food intake is recommended to monitor the situation closely.

5. The healthcare provider notes on the fetal monitor that a laboring client has a variable deceleration. Which action should the healthcare provider implement first?

• A. Assess cervical dilation.
• B. Change the client's position.
• C. Administer oxygen via facemask.
• D. Turn off the oxytocin infusion.

Correct answer: B

Rationale: Changing the client's position is the priority intervention for variable decelerations as it can relieve pressure on the umbilical cord, potentially resolving the deceleration and improving fetal oxygenation. Assessing cervical dilation, administering oxygen via facemask, and turning off the oxytocin infusion are important interventions but addressing the fetal distress caused by variable decelerations takes precedence.
