A 21-year-old patient with a history of asthma presents with sudden onset shortness of breath and difficulty breathing. Which characteristics would help the nurse practitioner make a differential diagnosis of an anaphylactic reaction?
Crackles on lung auscultation
Diffuse bilateral opacities on chest X-ray
Low-grade fever and facial pain
Orofacial swelling, a rash, and itching
The Correct Answer is D
Choice A reason: Crackles are indicative of pulmonary edema or infection, not typically anaphylaxis.
Choice B reason: Diffuse bilateral opacities suggest pneumonia or acute respiratory distress syndrome, not anaphylaxis.
Choice C reason: Low-grade fever and facial pain are more consistent with sinus infection or upper respiratory illness.
Choice D reason: This is correct. Anaphylaxis presents with sudden onset of symptoms including orofacial swelling, urticaria or rash, and pruritus, often accompanied by respiratory compromise and hypotension.

Correct Answer is B
Explanation
Choice A reason: Discontinuing the medication after only two weeks is premature. SSRIs like escitalopram typically require 4–6 weeks to achieve full therapeutic effect, so discontinuation at this point could prevent the patient from benefiting from treatment.
Choice B reason: Making no changes is appropriate because the patient is within the early stages of treatment. Her HAM-A score decreased slightly, and she reports no adverse effects, indicating she is tolerating the medication and may continue to improve with time. Monitoring and follow-up are the correct next steps.
Choice C reason: Adding an augmenting agent is unnecessary at this stage because the patient has only just begun therapy, and insufficient time has passed to determine the full effect of the SSRI. Augmentation is considered after an adequate trial of the primary medication.
Choice D reason: Switching to a different antidepressant is not indicated because there has been some improvement in her symptoms and she is tolerating the medication well. A switch is premature before completing an adequate trial period.
Correct Answer is C
Explanation
Choice A reason: Permanent deformity is not required for diagnosis, although it can occur in severe cases.
Choice B reason: Infection may occur but is not a necessary diagnostic criterion.
Choice C reason: Correct. The skin-picking must result in lesions, indicating that the behavior is causing physical damage and distress.
Choice D reason: Medical attention may be sought but is not required for the diagnosis.
