A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL How many mL should the nurse administer per dose?

(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 ["0.2"]

To calculate the volume of morphine sulfate to administer, we can use the following formula:

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

Plugging in the known values:

  • Dose = 2 mg
  • Concentration = 10 mg/mL

Volume (mL) = 2 mg / 10 mg/mL

Volume (mL) = 0.2 mL

Therefore, the nurse should administer 0.2 mL of morphine sulfate per dose.

Rounded to the nearest tenth: 0.2 mL

Correct Answer is A

Explanation

A. Apply 4 to 5 ml of liquid soap to the hands: This is the correct action. Applying an adequate amount of soap ensures effective cleaning of the hands. The recommended amount is typically 3 to 5 ml or enough to cover the entire surface of the hands.
B. Hold the hands higher than the elbows: This is incorrect. When performing hand hygiene, the hands should be held lower than the elbows to prevent water from running down the arms and contaminating previously cleaned areas.
C. Rub hands and arms to dry: This is incorrect. After washing the hands, they should be dried using a clean paper towel or air dryer. Rubbing hands and arms to dry is not recommended as it can lead to friction and potential skin irritation.
D. Adjust the water temperature to feel hot: This is incorrect. The water temperature should be warm, not hot, to prevent skin damage or discomfort. Hot water can strip the skin of its natural oils and lead to dryness or irritation.

Correct Answer is ["0.5"]

Explanation

Let's convert the digoxin dosage from mcg (micrograms) to mg (milligrams) and then divide it by the amount of digoxin per tablet to find out how many tablets are needed.

Steps to solve:

  1. Convert digoxin dose from mcg to mg:
    • We know 1 mg is equal to 1000 mcg.
    • Digoxin dose (mg) = Digoxin dose (mcg) / 1000 mcg/mg
    • Digoxin dose (mg) = 125 mcg / 1000 mcg/mg
    • Digoxin dose (mg) = 0.125 mg
  2. Calculate the number of tablets required:
    • Number of tablets = Digoxin dose (mg) / Digoxin per tablet (mg)
    • Number of tablets = 0.125 mg / 0.25 mg/tablet

Since the result is 0.5, we need to round to the nearest tenth.

Answer: The nurse should administer 0.5 tablets per dose.
