A nurse is preparing to administer morphine 0.1 mg/kg IM to a client who weighs 99 lb. Available is morphine 2 mg/mL. How many ml. should the nurse administer? (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 ["2.3"]

To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:

Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg

Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL

Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.

Correct Answer is ["300"]

Explanation

To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
1 Tbsp is approximately equal to 15 mL.
Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
Calculate the amount of guaifenesin in the client's dose:
Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.

Correct Answer is ["60"]

Explanation

To calculate the IV flow rate in gtt/min, you can use the following formula:

Flow rate (gtt/min) = (Volume to be infused (mL) x Drop factor) / Time (min)

In this case, the volume to be infused is 60 mL/hr, the drop factor is 60 gtt/mL, and we want to find the flow rate in gtt/min.

Flow rate (gtt/min) = (60 mL/hr x 60 gtt/mL) / 60 min

Flow rate (gtt/min) = (3600 gtt/hr) / 60 min

Flow rate (gtt/min) = 60 gtt/min
