A nurse is discussing the diagnosis of Duchenne muscular dystrophy (DMD) with the parents of an 8-year-old. She correctly explains:

DMD is a progressive loss of muscle strength and it will worsen over time.

this is a dominant disorder, so one of the parents likely also has DMD.

muscle function will gradually return, and recovery is possible in most children.

DMD results from an apparently toxic reaction to certain medications.

Answer and Explanation

The Correct Answer is A

Rationale:
A. Duchenne muscular dystrophy is a progressive, X-linked recessive disorder characterized by ongoing muscle fiber degeneration and weakness, typically worsening over time and leading to loss of ambulation and early death.
B. DMD is an X-linked recessive disorder, not dominant. Mothers are typically carriers, and males are affected. Parents are usually asymptomatic.
C. DMD has no cure, and spontaneous recovery of muscle function does not occur.

Correct Answer is B

Explanation

Rationale:
A. Presence of nits on the hair shaft is associated with pediculosis capitis (head lice), not scabies.
B. Line-like marks on the hands (especially between fingers) are characteristic of scabies, which is caused by mites burrowing under the skin.
C. Small, red bumps on the scalp are also associated with head lice, not scabies.
D. Pimples on the trunk can occur with various skin conditions, but burrow lines are more specific and diagnostic for scabies.

A. Give more pain medication. B. Perform a circulation assessment. C. Call the surgeon for orders. D. Change the child's position.

Correct Answer is B

Explanation

Rationale:
A. Administering more pain medication without assessing the cause of unrelieved pain could mask serious complications, such as compartment syndrome.
B. A circulation (neurovascular) assessment should be the first action to rule out complications such as impaired circulation or compartment syndrome, which can cause unrelieved or worsening pain even after analgesia.
C. The surgeon should be notified after an assessment has been completed and abnormal findings are confirmed.
D. Changing position might help with general discomfort but is not the priority when pain persists after opioid administration, which could indicate a serious issue.
