A patient with neuroleptic malignant syndrome has been prescribed dantrolene 1.5 mg/kg IV. The patient weighs 132 pounds.

The label on the 250 mg vial reads, “Reconstitute with 5 mL sterile water for injection, USP. Reconstitution yields 50 mg/mL.”. How many mL should the nurse administer?

Answer and Explanation

The Correct Answer is ["1.80"]

Step 1 is to convert the patient’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So, the patient’s weight in kilograms is 132 pounds ÷ 2.20462 = 59.87 kg.

Step 2 is to calculate the total dosage of dantrolene needed. The prescribed dosage is 1.5 mg/kg. So, the total dosage is 1.5 mg/kg × 59.87 kg = 89.81 mg.

Step 3 is to calculate the volume of reconstituted dantrolene solution needed to provide the total dosage. The reconstituted solution has a concentration of 50 mg/mL. So, the volume needed is 89.81 mg ÷ 50 mg/mL = 1.80 mL.

Correct Answer is A

Explanation

Choice A rationale
When a client’s blood pressure cannot be measured due to casts on both arms and the client’s position, the most appropriate action for the nurse is to document why the blood pressure cannot be accurately measured at the present time. This is because accurate measurement of blood pressure is crucial for monitoring the client’s health status and making appropriate clinical decisions. If the blood pressure cannot be measured accurately, it is important to document this fact along with the reasons why, so that other healthcare professionals are aware of the situation and can take appropriate action.
Choice B rationale
Advising the UAP to document the last blood pressure obtained on the client’s graphic sheet is not the most appropriate action in this situation. While it might provide some information about the client’s previous blood pressure readings, it does not address the current inability to measure the blood pressure. Furthermore, it could potentially lead to confusion or misinterpretation of the client’s current health status.
Choice C rationale
Demonstrating how to palpate the popliteal pulse with the client supine and the knee flexed is not the most appropriate action in this situation. While palpating the popliteal pulse can provide some information about the client’s circulatory status, it does not provide a measure of blood pressure. Furthermore, this action might not be feasible or appropriate depending on the client’s condition and the presence of casts on both arms.
Choice D rationale
Estimating the blood pressure by assessing the pulse volume of the client’s radial pulses is not the most appropriate action in this situation. While pulse volume can provide some information about the client’s circulatory status, it does not provide a measure of blood pressure. Furthermore, this method of estimating blood pressure is not as accurate or reliable as direct measurement.

A. Nadolol. B. Captopril. C. Digoxin. D. Hydrochlorothiazide.

Correct Answer is A

Explanation

Choice A rationale

Nadolol is a beta-blocker that can decrease heart rate and contractility, which can potentially exacerbate heart failure and lead to cardiogenic shock.

Choice B rationale

Captopril is an angiotensin-converting enzyme (ACE) inhibitor that is often used in the treatment of heart failure. It works by relaxing blood vessels and reducing the workload of the heart.

Choice C rationale

Digoxin is a cardiac glycoside that is used to treat heart failure and certain heart arrhythmias. It works by increasing the force of the heart’s contractions, which can improve heart function.

Choice D rationale

Hydrochlorothiazide is a diuretic that is often used in the treatment of heart failure. It works by helping the body get rid of excess fluid, which can reduce the workload of the heart.
