The nurse retrieves hydromorphone "4 mg/mL" from the electronic medication system, for a patient who is receiving hydromorphone 3 mg IM every 6 hours PRN for severe pain. How many mL should the nurse administer to the patient? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The nurse needs to administer hydromorphone 3 mg to the patient. The concentration of the hydromorphone solution is 4 mg/mL. To find out how many mL the nurse should administer, we can use the formula:
The Correct Answer is ["0.8"]
Amount (mg) ÷ Concentration (mg/mL) = Volume (mL)
Step 1: The amount of hydromorphone the patient needs is 3 mg. Step 2: The concentration of the hydromorphone solution is 4 mg/mL. Step 3: Substitute the values into the formula: 3 mg ÷ 4 mg/mL.
Step 4: Calculate the volume: 3 ÷ 4 = 0.75 mL. 0.8 rounded to the nearest tenth

Correct Answer is B
Explanation
Choice A reason: Analogies can be useful for explaining concepts but may not provide the hands-on practice needed for managing confrontational situations.
Choice B reason: Role-playing is an effective strategy for practicing communication skills, as it allows staff to simulate and navigate difficult conversations in a controlled environment.
Choice C reason: Return demonstration is typically used for teaching psychomotor skills and may not be as effective for communication training.
Choice D reason: Journaling is a reflective practice but does not offer the interactive experience needed to prepare for real-life scenarios involving angry family members.
Correct Answer is A
Explanation
Choice A reason: The presence of soft, formed, and light brown feces is normal and does not preclude testing for occult blood. The nurse should proceed with obtaining the specimen as ordered.
Choice B reason: There is no need to contact the healthcare provider before obtaining the specimen if the stool appears normal and the test for occult blood has been ordered.
Choice C reason: Waiting for observable blood is not necessary for an occult blood test, which is designed to detect blood that is not visible to the naked eye.
Choice D reason: Withholding specimen collection until tarry black stool is observed is not indicated. Tarry black stool can indicate bleeding in the upper gastrointestinal tract, but the test for occult blood is used to detect blood that may not be visible in the stool.
