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 D
Explanation
A. "Crushing the medication might cause you to have a stomachache or indigestion."
This response provides a potential adverse effect of crushing the medication but does not directly address the reason why the aspirin should not be crushed.
B. "Crushing the medication is a good idea, and I can mix it in some ice cream for you."
This response suggests a solution to the client's difficulty swallowing medication but does not address the safety or efficacy concerns associated with crushing enteric-coated aspirin.
C. "Crushing is unsafe, as it destroys the ingredients in the medication."
While crushing enteric-coated aspirin may alter its release properties, it does not necessarily "destroy" the ingredients. This statement may be too absolute and not entirely accurate.
D. "Crushing the medication would release all the medication at once, rather than over time."
This response accurately explains why enteric-coated aspirin should not be crushed. Enteric coating is designed to prevent dissolution of the medication in the stomach and instead release it in the small intestine to reduce the risk of gastric irritation or ulceration. Crushing the medication would bypass this delayed release mechanism, potentially leading to increased gastric irritation or adverse effects.
Correct Answer is C
Explanation
A. A room with another nonsurgical client: Placing a client with active tuberculosis in a room with another nonsurgical client is not appropriate because it increases the risk of transmission to other patients. Tuberculosis is highly contagious, and isolation precautions are necessary to prevent the spread of the disease.
B. A room in the ICU: While isolation precautions are necessary for a client with active tuberculosis, placing the client in the intensive care unit (ICU) may not be necessary unless the client requires critical care. However, the priority is to provide a room that meets the requirements for airborne infection isolation, which may not necessarily be in the ICU.
C. A room with air exhaust directly to the outdoor environment: This is the correct choice. A room with air exhaust directly to the outdoor environment is essential for a client with active tuberculosis. Airborne infection isolation rooms (AIIRs) have negative air pressure and special ventilation systems that prevent the circulation of air from the room to other areas of the healthcare facility, reducing the risk of transmission to healthcare workers and other patients.
D. A room that is within view of the nursing station: While it may be convenient for the nursing staff to have the client's room within view of the nursing station for monitoring purposes, the priority for a client with active tuberculosis is to ensure that they are placed in a room with appropriate airborne infection isolation precautions, including proper ventilation, to minimize the risk of transmission to others.
