Which number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters?
3.1
2.54
0 2.25
2.75
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.

Explanation
To calculate the infusion rate, we need to convert the patient's weight from kilograms to milligrams.
Patient's weight: 65 kg
Dose required: 200 mcg/kg/min
First, let's calculate the total dose required for the patient per minute: Dose required = 200 mcg/kg/min * 65 kg
= 13,000 mcg/min
Next, we need to convert the dose from micrograms to milligrams:
13,000 mcg/min = 13 mg/min
Now, let's determine the infusion rate. We have 2,500 mg of esmolol in 250 mL of fluid. Therefore, the concentration of esmolol in the fluid is:
Concentration = 2,500 mg / 250 mL
= 10 mg/mL
To find the infusion rate, we divide the dose required by the concentration: Infusion rate = 13 mg/min / 10 mg/mL
= 1.3 mL/mi
Since the options are in mL/hr, we need to convert the rate from mL/min to mL/hr:
1.3 mL/min * 60 min/hr = 78 mL/hr
Therefore, the correct answer is:
a. 78 mL/hr
Correct Answer is D
Explanation
The nurse should administer 0.5 mL to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
2 mg / 1 mL = 1 mg / x mL
Cross-multiplying and solving for x gives:
x = 0.5 mL
Therefore, the nurse should administer 0.5 mL of Stadol injection to deliver 1 mg of the medication to the patient.
