A 15-year-old patient is to receive antihemophilic factor (Factor VIll) replacement therapy. He asks the nurse, "Why does this always happen to me? How come my sisters don't have hemophilia?”. The nurse's response should be based on the understanding that hemophilia is characteristic of which type of hereditary disorder?
X-linked dominant.
Autosomal recessive.
Autosomal dominant.
X-linked recessive.
The Correct Answer is D
Choice A rationale:
X-linked dominant disorders are characterized by a mutation on the X chromosome that results in the expression of the trait in both males and females. Hemophilia, however, is more commonly associated with males, which is not consistent with an X-linked dominant pattern.
Choice B rationale:
Autosomal recessive disorders require the inheritance of two mutated alleles, one from each parent, to express the trait. Hemophilia does not follow this pattern, as the patient's sisters do not have the condition despite having affected parents.
Choice C rationale:
Autosomal dominant disorders only require the inheritance of one mutated allele from an affected parent to express the trait. Hemophilia does not align with an autosomal dominant pattern, as the patient's sisters would likely be affected if it were.
Choice D rationale:
Hemophilia is a classic example of an X-linked recessive disorder. The gene responsible for producing clotting factor is located on the X chromosome, and males have only one X chromosome, making them more susceptible to the disorder. Females, with two X chromosomes, usually act as carriers unless both X chromosomes carry the mutation.

Correct Answer is D
Explanation
Choice A rationale:
Assessing the infant's ability to roll over is unrelated to the situation. The nurse's focus should be on safely retrieving the nasogastric tube without leaving the infant alone.
Choice B rationale:
Using a nesting pillow is not appropriate in this scenario. The nurse should prioritize getting the nasogastric tube rather than introducing unnecessary items into the crib.
Choice C rationale:
Putting the side rail all the way up might hinder the nurse's ability to access the counter and the nasogastric tube. It is not the most effective action in this situation.
Choice D rationale:
Calling for assistance ensures that the infant's safety is maintained while the nurse retrieves the nasogastric tube. Leaving the infant unattended increases the risk of harm, so involving someone else is the appropriate action.
Correct Answer is C
Explanation
Choice A rationale:
Exploring why the mother wants to hold the baby is important, but it does not directly address her immediate desire to hold her baby. Delaying the action could lead to emotional distress for the mother.
Choice B rationale:
Showing the mother how to lightly rub the baby's back above the suture line might be appropriate, but it doesn't fulfill the mother's wish to hold her baby. It also doesn't fully consider the sensitivity of the surgical site.
Choice C rationale:
Helping the mother hold the baby without placing pressure on the suture line is the most appropriate action. It addresses the mother's emotional needs while also considering the infant's post-operative condition.
Choice D rationale:
Reassuring the mother that she will be able to hold her baby in four to five days does not provide immediate comfort and support for her emotional distress. It's important to address her needs in the present moment.
