A nurse is preparing to administer clonazepam 1.5 mg PO in 3 equally divided doses every 8 hr for a client who has seizures. The amount available is clonazepam 0.5 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

To calculate the number of tablets, divide the total dose by the dose per tablet. In this case, the total dose is 1.5 mg / 3 = 0.5 mg and the dose per tablet is 0.5 mg. Therefore,

(number of tablets) = (0.5 mg) / (0.5 mg) = 1 tablet

Round the answer to the nearest tenth and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should administer 1 tablet per dose.

Correct Answer is D

Explanation

Hypokalemia is a low serum potassium level, usually below 3.5 mEq/L. It can be caused by diuretics that increase potassium excretion, such as thiazides or loop diuretics. Potassium is essential for normal muscle and nerve function, and hypokalemia can impair cardiac, skeletal, and smooth muscle activity. Symptoms of hypokalemia include fatigue, weakness, muscle cramps, arrhythmias, constipation, and hyporeﬂexia.

Dyspnea is difficulty or labored breathing that can be caused by various respiratory or cardiac conditions, such as asthma, pneumonia, pulmonary edema, or heart failure. It is not a specific sign of hypokalemia, although severe hypokalemia can aﬀect respiratory muscle function and cause respiratory failure.
Oliguria is a reduced urine output, usually less than 400 mL per day or 30 mL per hour. It can be caused by various renal or ﬂuid balance disorders, such as acute kidney injury, dehydration, or shock. It is not a specific sign of hypokalemia, although severe hypokalemia can impair renal function and cause renal failure.
Pitting edema is a swelling of the tissues that leaves an indentation when pressed with a finger. It can be caused by various ﬂuid retention disorders, such as heart failure, liver cirrhosis, or nephrotic syndrome. It is not a specific sign of hypokalemia, although severe hypokalemia can aﬀect ﬂuid and electrolyte balance and cause edema.

Correct Answer is ["75"]

Explanation

To calculate the infusion rate, divide the volume of ﬂuid by the time in hours. In this case, 1800 mL / 24 hr = 75 mL/hr.

Round the answer to the nearest whole number and use a leading zero if it applies.

Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 75 mL/hr.
