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 ["200"]

Explanation

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

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

First, convert minutes to hours:

75 minutes x (1 hour / 60 minutes) = 1.25 hours

Then, plug in the values into the formula:

Infusion Rate = 250 mL / 1.25 hours

Calculating the result:

Infusion Rate ≈ 200 mL/hour

Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.

Correct Answer is ["22"]

Explanation

Calculating the Propofol Infusion Rate

Step 1: Convert weight to kilograms:

198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 90 kg = 720 mcg/minute

Step 3: Calculate the concentration of propofol in the IV solution:

100 mg/50 mL = 2 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute

Then, set up a proportion:

x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL

x mL/hour ≈ 21.6 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.
