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.

Correct Answer is ["7"]

Explanation

To calculate the correct dosage of levothyroxine, the nurse should follow these steps:

Convert the patient's weight from pounds to kilograms: 220 lb ÷ 2.20462 lb/kg = 99.79 kg
Calculate the total dose of levothyroxine: 5 mcg/kg × 99.79 kg = 498.95 mcg
Determine the number of tablets to administer: 498.95 mcg ÷ 75 mcg/tablet = 6.65 tablets

Therefore, the nurse should administer 7 tablets of levothyroxine.
