Nursing Elites

1. 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.

2. A primipara patient asks what is the best pet to have at home to share time with. Which pet is not recommended?

• A. Dog
• B. Cat
• C. Bird
• D. Fish

Correct answer: C

Rationale: Birds are not recommended as pets for a primipara patient due to potential health risks associated with bird droppings, feathers, and dander. These factors may pose a risk to the newborn's health and the mother's well-being. Additionally, some birds can be loud, which may disrupt the baby's sleep patterns. Therefore, it is advisable for primipara patients to consider pets like dogs, cats, or fish as they generally have lower associated risks in a household with a newborn. Dogs, cats, and fish are relatively safer options compared to birds for primipara patients due to their lower risk of transmitting infections, allergens, or causing disturbances that could affect the newborn or the mother.

3. During a well-child visit for their child, one of the parents with an autosomal dominant disorder tells the nurse, 'We don’t plan on having any more children, since the next child is likely to inherit this disorder.' How should the nurse respond?

• A. Explain that the risk of inheriting the disorder decreases by 50% with each child the couple has.
• B. Acknowledge that the next child will inherit the disorder since the first child did not.
• C. Encourage the couple to reconsider their decision since the inheritance pattern may be sex-linked.
• D. Confirm that there is a 50% chance of their future children inheriting the disorder.

Correct answer: D

Rationale: Confirming that there is a 50% chance of their future children inheriting the disorder is the correct response in this situation. Autosomal dominant disorders have a 50% chance of being passed on to each child. Providing accurate genetic counseling is essential to help the parents make informed decisions about family planning. Choices A, B, and C are incorrect. Choice A is inaccurate because the risk of inheriting an autosomal dominant disorder remains at 50% for each child regardless of the number of children the couple has. Choice B is not appropriate as it does not provide helpful information or support to the parents. Choice C is misleading because autosomal dominant disorders follow a specific inheritance pattern and are not sex-linked.

4. A one-day-old neonate develops a cephalohematoma. The nurse should closely assess this neonate for which common complication?

• A. Jaundice.
• B. Poor feeding.
• C. Brain injury.
• D. Hypoglycemia.

Correct answer: A

Rationale: A cephalohematoma is a collection of blood between the skull and the periosteum. As the blood breaks down, there is an increased risk of jaundice due to the release of bilirubin from the breakdown of red blood cells. Jaundice is a common complication associated with cephalohematoma in neonates. Therefore, the nurse should closely monitor the neonate for signs of jaundice and manage it accordingly.

5. A client who had her first baby three months ago and is breastfeeding her infant tells the nurse that she is currently using the same diaphragm that she used before becoming pregnant. What information should the nurse provide this client?

• A. Use an alternative form of contraception until a new diaphragm is obtained.
• B. After weaning, the diaphragm should be resized.
• C. Avoid intercourse during ovulation until the diaphragm size is reassessed.
• D. If weight gain during pregnancy was no more than 20 pounds, the diaphragm is safe to use.

Correct answer: A

Rationale: The nurse should advise the client to use an alternative form of contraception until a new diaphragm that fits correctly post-pregnancy is obtained. It is essential to ensure proper fit for effective contraception, making it crucial to use an alternative method until the diaphragm is resized.
