A nurse is preparing to administer belimumab 10 mg/kg via intermittent IV bolus to a client who weighs 136 lb. Available is belimumab 80 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
To calculate the amount of belimumab that the nurse should administer, we can use the following steps:
Convert the patient's weight from pounds to kilograms.
Multiply the patient's weight in kilograms by the dosage of belimumab (10 mg/kg) to find the total dosage required.
Determine the volume of the drug needed using the concentration of the available belimumab solution.
Given:
Patient's weight = 136 lb
Dosage of belimumab = 10 mg/kg
Available concentration of belimumab = 80 mg/mL
Let's calculate step by step:
Convert patient's weight from pounds to kilograms:
Patient's weight in kg = 136 lb × (1 kg / 2.2 lb) ≈ 61.8 kg
Calculate the total dosage required:
Total dosage = 10 mg/kg × 61.8 kg ≈ 618 mg
Determine the volume of the drug needed using the concentration of the available belimumab solution:
Volume of drug = Total dosage / Concentration of belimumab
Volume of drug = 618 mg / 80 mg/mL ≈ 7.7 mL
Rounding to the nearest whole number, the nurse should administer 8 mL of the belimumab.

Correct Answer is ["A","B"]
Explanation
Choice A reason: Age is a non-modifiable risk factor for hypertension because the risk of high blood pressure increases as we get older. This is due to changes in the heart and blood vessels, such as loss of elasticity and stiffening of the arteries, that affect the blood flow and pressure. ¹
Choice B reason: Genetics is a non-modifiable risk factor for hypertension because some people inherit genes that make them more likely to develop high blood pressure. For example, people of African and Black Caribbean descent have a higher risk of hypertension due to genetic variations that affect salt sensitivity and blood vessel function. ²
Choice C reason: Smoking is a modifiable risk factor for hypertension because it can be changed or avoided by quitting tobacco use. Smoking damages the blood vessels and increases the risk of atherosclerosis, which is the buildup of plaque in the arteries that narrows them and raises blood pressure. Smoking also lowers the level of good cholesterol (HDL) and raises the level of bad cholesterol (LDL) and triglycerides, which are fats in the blood that contribute to plaque formation. ³
Choice D reason: Obesity is a modifiable risk factor for hypertension because it can be changed or prevented by losing weight or maintaining a healthy weight. Obesity increases the risk of high blood pressure by putting extra strain on the heart and blood vessels, as well as by causing hormonal and metabolic changes that affect blood pressure regulation. Obesity is also associated with other conditions that can raise blood pressure, such as diabetes, sleep apnea, and kidney disease. ⁴
Choice E reason: Sedentary lifestyle is a modifiable risk factor for hypertension because it can be changed or improved by increasing physical activity. Sedentary lifestyle increases the risk of high blood pressure by reducing the ability of the blood vessels to dilate and contract, as well as by increasing the risk of obesity, diabetes, and high cholesterol. Physical activity helps to lower blood pressure by improving blood flow, strengthening the heart muscle, and lowering body weight and stress levels. .
Correct Answer is ["10"]
Explanation
The nurse needs to administer 775 mg of amoxicillin. The available amoxicillin oral suspension is 400 mg/5 mL, which means there are 400 mg of amoxicillin in every 5 mL of the suspension.
Therefore, for a 775 mg dose, the nurse should administer:
775 mg/(400 mg/5mL) = 9.6875 mL of the suspension
So, the nurse should administer approximately 10 mL (rounded to the nearest whole number).
