A nurse is preparing to administer methylprednisolone sodium succinate 30 mg/kg via intermittent IV bolus to a client who weighs 169 lb. Available is methylprednisolone sodium succinate 125 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.)

Answer and Explanation

The Correct Answer is ["18"]

To calculate the dose of methylprednisolone sodium succinate that the nurse should administer, we can follow these steps:

Convert the client's weight from pounds to kilograms:

169 lb ÷ 2.2 = 76.82 kg (rounded to two decimal places)

Calculate the dose of methylprednisolone sodium succinate:

30 mg/kg × 76.82 kg = 2,304.6 mg

Determine the volume of methylprednisolone sodium succinate needed using the available concentration:

2,304.6 mg ÷ 125 mg/mL = 18.437 mL

Rounding to the nearest whole number, the nurse should administer 18 mL of methylprednisolone sodium succinate via intermittent IV bolus.

Correct Answer is ["5"]

Explanation

To calculate the volume of hydrochlorothiazide oral solution that the nurse should administer per dose, we can use the following steps:

Determine the total daily dose:

The total daily dose is 150 mg.

Divide the total daily dose into 3 equally divided doses:

150 mg ÷ 3 = 50 mg per dose

Calculate the volume to be administered per dose:

The available oral solution has a concentration of 50 mg/5 mL.

50 mg ÷ 50 mg/5 mL = 5 mL

Therefore, the nurse should administer 5 mL of hydrochlorothiazide oral solution per dose.

A. 28 year old woman with pregnancy-induced hypertension B. Pizza delivery driver with 5 year history of smoking C. Client with a history of uncontrolled asthma D. 55 year old male who had a myocardial infarction 2 days ago

Correct Answer is C

Explanation

Choice A reason: This is incorrect because labetalol is a safe and effective medication for treating hypertension in pregnancy. Labetalol is a beta-blocker that lowers blood pressure by reducing the heart rate and the force of contraction. It does not affect the blood flow to the placenta or the fetus.

Choice B reason: This is incorrect because labetalol is not contraindicated for smokers. However, smoking is a risk factor for cardiovascular disease and should be discouraged by the nurse. Smoking can increase blood pressure, heart rate, and the risk of blood clots.

Choice C reason: This is correct because labetalol is contraindicated for clients with a history of uncontrolled asthma. Labetalol is a non-selective beta-blocker that can block the beta-2 receptors in the lungs and cause bronchoconstriction. This can worsen asthma symptoms and trigger an asthma attack.

Choice D reason: This is incorrect because labetalol is a suitable medication for clients who had a myocardial infarction. Labetalol can prevent further damage to the heart muscle by reducing the oxygen demand and the workload of the heart. It can also prevent arrhythmias and angina.
