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 ["0.7"]

Explanation

To calculate the dosage of morphine for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The nurse also needs to divide the resulting amount by the concentration of the morphine injection to get the volume to be administered. The formula is:

Volume (mL) = (Weight (kg) x Dose (mg/kg)) / Concentration (mg/mL)

In this case, the child weighs 77 lb, which is equivalent to 35 kg (77 / 2.2 = 35). The prescribed dose is 0.2 mg/kg and the concentration of the morphine injection is 10 mg/mL. Therefore, the volume to be administered is:

Volume (mL) = (35 x 0.2) / 10

Volume (mL) = 0.7

The nurse should round the answer to the nearest tenth, which is 0.7 mL.
