Answer to Question 1
B
Hand hygiene is the most effective single act that can reduce the spread of disease. Antibiotics should not be taken at the first sign of infection, especially if the infection is caused by a virus; vaccinations can also prevent diseases from occurring; a nutritious diet is only one component in the prevention of infection.
Answer to Question 2
D
With sulfa drugs, it is most important for the patient to maintain a fluid intake of at least 3000 mL (1.5 L) in order to prevent crystalluria and stone formation. Ambulation does not directly correlate to the sulfa drug in any way. Investigating an allergy is an assessment, not an interven-tion, and this action should occur prior to administering the first dose. Daily weights are impor-tant for tracking inputs and outputs, but it is not the priority intervention.
