Try Naxlex NCLEX-RN (Free-Trial)

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 ["40"]

Explanation

Calculating the Inamrinone Infusion Rate

Step 1: Convert weight to kilograms:

183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg

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

8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute

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

0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL

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

First, convert mcg to mg:

664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute

Then, set up a proportion:

x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL

x mL/hour ≈ 40 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
