Which number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters?

A.

3.1

B.

2.54

C.

0 2.25

D.

2.75

Answer and Explanation

The Correct Answer is B

This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:

centimeters = inches × 2.54

For example, if a patient's height is 60 inches, then the height in centimeters is:

centimeters = 60 × 2.54
centimeters = 152.4

Therefore, the patient's height is 152.4 centimeters.

Correct Answer is B

Explanation

QD is an abbreviation for "quaque die" which means "every day" in Latin. However, QD is on the official "Do Not Use" list of the Joint Commission because it can be mistaken for QOD, which means "every other day" in Latin¹². This can lead to medication errors and patient harm. Therefore, the Joint Commission recommends writing "daily" instead of QD.

The other options are not on the official "Do Not Use" list of the Joint Commission. OS, PO, and OD are abbreviations for "oculus sinister" (left eye), "per os" (by mouth), and "oculus dexter" (right eye) respectively. They are commonly used in ophthalmology and pharmacy³. However, they should be used with caution and only when appropriate, as they can also be confused with other abbreviations or symbols.

Correct Answer is B

Explanation

Step 1 is Convert pounds to kilograms 110 lb ÷ 2.2 = 50 kg

Step 2 is Calculate dose in micrograms per minute 50 kg × 200 micrograms = 10,000 micrograms/min

Step 3 is Convert micrograms to milligrams 10,000 micrograms ÷ 1000 = 10 mg/min

Step 4 is Convert mg/min to mg/hr 10 mg × 60 = 600 mg/hr

Step 5 is Determine concentration of esmolol in mg/mL 2.5 grams × 1000 = 2500 mg 2500 mg ÷ 250 mL = 10 mg/mL

Step 6 is Calculate infusion rate in mL/hr 600 mg/hr ÷ 10 mg/mL = 60 mL/hr
