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.)
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 ["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:
- 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
- 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.
Correct Answer is D
Explanation
A. Complete an incident report: While completing an incident report is important for documentation purposes, it should not be the first action taken after a needle stick injury. Immediate attention to the wound by washing it with soap and water takes precedence to minimize the risk of infection.
B. Consent to postexposure treatment with antiretroviral medications: Postexposure prophylaxis (PEP) with antiretroviral medications may be indicated after a needle stick injury, particularly if there is a risk of exposure to HIV or other bloodborne pathogens. However, obtaining consent for PEP should follow immediate wound care.
C. Request the risk manager obtain consent for HIV testing from the client: While HIV testing may be necessary for the client involved in the incident, it is not the nurse's responsibility to obtain consent for testing. The priority is to address the nurse's own immediate health and safety by cleaning the wound and seeking appropriate medical evaluation and treatment.
D. Wash the site of injury with soap and water: The first action the nurse should take after experiencing a needle stick injury is to immediately wash the site of the injury with soap and water. This helps reduce the risk of infection by removing any potentially infectious material from the wound.
