A 22 kg patient has an order for cefazolin 500 mg IV every 6 hours. The safe dose is 50 mg/kg/day. Is the ordered dose safe for the patient?
The Correct Answer is ["No"," the ordered dose is not safe for the patient."]
Calculate the Maximum Safe Daily Dose (mg/day)
Patient weight: 22 kg
Maximum safe dose: 50 mg/kg/day
Maximum Safe Daily Dose = 22 kg x 50 mg/kg/day
= 1,100 mg/day
Calculate the Total Ordered Daily Dose (mg/day)
Ordered dose per administration: 500 mg
Frequency: Every 6 hours (4 doses per day)
Total Ordered Daily Dose = 500 mg/dose x 4 doses/day
= 2,000 mg/day
The Total Ordered Daily Dose (2,000 mg/day) is greater than the Maximum Safe Daily Dose (1,100 mg/day). The ordered dose is unsafe.

Correct Answer is ["5.3"]
Explanation
Convert the child's weight from pounds (lb) to kilograms (kg)
Given weight = 28 lb
Conversion factor: 1 kg = 2.2 lb
Weight (kg) = 28 lb / 2.2 lb/kg
= 12.727 kg
Calculate the Single Dose in milligrams (mg)
Prescribed dose = 10 mg/kg/dose
Single Dose (mg) = Weight (kg) x Dose (mg/kg/dose)
= 12.727 kg x 10 mg/kg
= 127.272 mg
Calculate the Volume (mL) to Administer (Dose/Have Method)
Ordered Dose (D) = 127.272... mg
Available Dose (H) = 120 mg
Quantity (Q) = 5 mL
Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q)
= (127.272 mg / 120 mg) x 5 mL
= 1.0606 x 5 mL
= 5.303 mL

Correct Answer is ["Human chorionic gonadotropin (hCG)"]
Explanation
Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG), which is produced by trophoblastic cells of the developing placenta shortly after implantation. hCG maintains the corpus luteum, allowing continued secretion of progesterone to support the early pregnancy. Its levels rise rapidly in the first trimester, making it a reliable indicator of pregnancy in both urine and blood samples.
