Explanation
A. An allergic reaction is an immune response to a medication, even if the patient has taken the medication before without issues. Symptoms like hives and itching are classic signs of an allergic reaction.
B. A side effect is an expected, often mild and predictable reaction to a medication, not typically involving an immune response and severe symptoms like hives.
C. A toxic effect refers to harmful effects from a medication overdose or accumulation in the body, not sudden onset after an appropriate dose.
D. An idiosyncratic reaction is an uncommon response not related to allergies or toxic effects, usually not presenting with hives and itching.
Correct Answer is ["C","D","E"]
Explanation
A. Bilateral breath sounds clear and present throughout at 1600 are normal findings and do not require immediate follow-up.
B. The temperature at both 1600 (37.6°C) and 1630 (37.5°C) is slightly elevated but not critically high. It does not require immediate follow-up unless it worsens significantly or is accompanied by other concerning symptoms.
C. Urticaria (hives) over the chest and trunk, along with itching and difficulty swallowing (dysphagia), are signs of an allergic reaction, which requires immediate follow-up and assessment.
D. The blood pressure decreased to 78/52 mm Hg at 1630 from 110/58 mm Hg at 1600. This significant drop indicates hypotension and requires immediate follow-up.
E. Difficulty swallowing (dysphagia) reported by the client suggests a potential airway compromise and requires immediate follow-up to assess the severity and intervene accordingly.
