Oral medications are often used as an early treatment for generalized spasticity. Which of the following works at the level of skeletal muscle to block calcium release from the sarcoplasmic reticulum?

Correct Answer: A

Rationale: Dantrolene sodium directly acts on skeletal muscles by inhibiting calcium release from the sarcoplasmic reticulum, thereby reducing muscle contraction and spasticity.

Correct Answer: D

Rationale: In the management of anaphylaxis, the priority action for the nurse is to administer IM epinephrine to the child. Epinephrine is the first-line treatment for anaphylaxis as it helps reverse the severe manifestations of the reaction by constricting blood vessels, relaxing airway muscles, and decreasing hives and swelling. Elevating the head of the child's bed may be beneficial for respiratory distress but is not the priority over administering epinephrine. Inserting a large-bore IV catheter may be necessary for fluid resuscitation but is not the initial priority. Identifying the allergen is important for prevention and future management but is not the immediate action needed in the acute phase of an anaphylactic reaction.

Correct Answer: C

Rationale: Malignant hyperthermia typically presents with rapid onset fever, hypercarbia, and muscle rigidity, but ventricular fibrillation is not a common feature.

Correct Answer: B

Rationale: Encouraging the child to perform independent self-care is essential when managing juvenile idiopathic arthritis. This instruction helps minimize pain and stiffness in the child's joints while promoting mobility and independence. It is crucial for the child to learn self-management skills early to cope better with the condition in the long term.

Correct Answer: A

Rationale: Many children outgrow stuttering naturally.
