Which of the following clients would the nurse question an order for labetalol 50 mg PO?

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. .

To calculate the amount of ampicillin the nurse should administer per dose in milliliters (mL) for a 500 mg IM dose, we can use the following steps:

Given:

Ampicillin dose: 500 mg

Available concentration after reconstitution: 250 mg/mL

Volume of sterile water to be added: 1.8 mL

Step 1: Calculate the amount of ampicillin to be administered per dose in mL

First, we need to reconstitute the ampicillin vial to yield the desired concentration of 250 mg/mL.

The concentration after reconstitution is 250 mg/mL, and the total dose required is 500 mg. Therefore, the nurse needs to administer:

Volume = Ampicillin dose / Concentration

Volume = 500 mg / 250 mg/mL

Volume = 2 mL

Rounding to the nearest whole number:

Volume = 2 mL

Therefore, the nurse should administer 2 mL of the reconstituted ampicillin solution per dose.
