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

Explanation

Calculating the Trimethoprim-Sulfamethoxazole Dose

Problem: Administer 120 mg of Bactrim-DS Oral Suspension. The available concentration is 200 mg/5 mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (120 mg) and the concentration of the medication (200 mg/5 mL).

Proportion:

x mL / 120 mg = 5 mL / 200 mg

Cross-multiply:

200x = 600

Solve for x:

x = 600 / 200

x = 3

Answer: The nurse should administer 3 mL of Bactrim-DS Oral Suspension per dose.

Correct Answer is ["167"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

Plugging in the given values:

Infusion Rate = 1000 mL / 6 hours

Calculating the result:

Infusion Rate ≈ 166.67 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour
