Mary is excited to work with the family of a friend with whom she has lost contact. Mary hopes the family will be able to connect her with her friend and is looking forward to hearing about her friend. At the next session, she asks the mother many questions about her friend and they spend a lot of time discussing their home town, etc. Which statement describes this scenario?
- A. It is not therapeutic: The relationship serves no purpose
- B. It is therapeutic: Therapist, child, and family have a reciprocal caring relationship
- C. It is not therapeutic: Mary is benefiting, but not the child and family
- D. It is therapeutic: Both parties are benefiting in the relationship
Correct Answer: C
Rationale: In this scenario, Mary's focus on her own needs and interests by asking the mother about her lost friend and hometown indicates a lack of therapeutic benefit for the child and family. Effective therapy should prioritize the needs and goals of the child and family, not the therapist's personal desires or connections. Therefore, this interaction is not therapeutic as it fails to address the primary purpose of the therapy, which is to benefit the child and family.

A patient develops hypotension, laryngeal edema, and bronchospasm after eating peanuts. Which medication should the nurse prepare to administer?
- A. Promethazine
- B. Epinephrine
- C. Diphenhydramine
- D. Hydroxyzine
Correct Answer: B
Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, which is a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis and may not address the severe manifestations seen in this case.
