Correct Answer is ["0.7"]
Explanation
To calculate the dosage of diphenhydramine injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 35 mg, H is 50 mg/mL, and Q is 1 mL.
Plugging these values into the formula, we get:
35 mg / 50 mg/mL x 1 mL = 0.7 mL
Therefore, the nurse should administer 0.7 mL of diphenhydramine injection.
Correct Answer is ["10"]
Explanation
To give a patient cetirizine 5 mg PO, the nurse needs to measure the correct amount of liquid medicine. The medicine has a concentration of cetirizine 2.5 mg/5 mL, which means that every 5 mL of liquid contains 2.5 mg of cetirizine.
To find out how many mL of liquid are equivalent to 5 mg of cetirizine, the nurse can use a proportion:
2.5 mg / 5 mL = 5 mg / x mL
Cross-multiplying and solving for x, the nurse gets:
x = (5 mL x 5 mg) / 2.5 mg
x = 10 mL
Therefore, the nurse should administer 10 mL of liquid medicine to give the patient cetirizine 5 mg PO.
