The health-care provider prescribes nitroglycerin 0.6 mg sub-lingual (SL) PRN for chest pain for a client with chronic stable angina. The medication is available in 0.4 mg tablets. How many tablets should the nurse administer if the client experiences chest pain? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["2"]

To determine the number of tablets needed, we can set up a proportion:

x tablets / 0.6 mg = 1 tablet / 0.4 mg

Cross-multiplying:

0.4x = 0.6

Solving for x:

x = 0.6 / 0.4

x = 1.5

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets of nitroglycerin 0.4 mg sublingually if the client experiences chest pain

Correct Answer is C

Explanation

To calculate the volume of amoxicillin to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

Plugging in the given values:

Volume (mL) = 500 mg / 125 mg/mL

Calculating the result:

Volume (mL) = 20 mL

Therefore, the nurse should administer 20 mL of amoxicillin.

The correct answer is C. 20 ml.

Correct Answer is ["10.5"]

Explanation

To calculate the volume of pyridostigmine to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

However, the concentration is given in mg/5 mL. We need to convert it to mg/mL:

Concentration (mg/mL) = 60 mg / 5 mL = 12 mg/mL

Now, plug in the given values into the formula:

Volume (mL) = 126 mg / 12 mg/mL

Volume (mL) = 10.5 mL

Therefore, the nurse should administer 10.5 mL of pyridostigmine syrup.
