Correct Answer is B

Explanation

A. Diarrhea: Diarrhea is a common side effect of antibiotics due to their effect on the gut microbiota, but it is not typically indicative of an allergy.
B. Hives or shortness of breath: Hives (urticaria) and shortness of breath are classic symptoms of an allergic reaction. Hives indicate an immediate hypersensitivity reaction, and shortness of breath can indicate a serious allergic reaction such as anaphylaxis. These symptoms warrant caution and further assessment before starting antimicrobial therapy.
C. Headaches: Headaches can be a side effect of various medications but are not a specific sign of a drug allergy.
D. Nausea: Nausea is a common side effect of many medications, including antibiotics, but it does not specifically indicate an allergic reaction.

Correct Answer is ["0.5"]

Explanation

To determine the correct volume to administer, we use the formula for calculating the dose:
Volume to administer=Prescribed dose ÷ Available concentration
Given:
● Prescribed dose: 1 mg
● Available concentration: 1 mg per 0.5 mL
Plugging in the values:
Volume to administer=1 mg÷ 1 mg/0.5 ml
Perform the division:
Volume to administer=0.5 mL
So, the nurse should administer 0.5 mL per dose.
Since the question specifies rounding to the nearest tenth and to use a leading zero if it applies (and not to use a trailing zero), the final answer is: 0.5 mL
