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 C
Explanation
The correct answer is choice C. “This must be a very difficult time for you.”
Choice A rationale:
Asking the mother why she thinks it is her fault can make her feel defensive and does not provide the emotional support she needs at this moment. It may also imply that there could be a reason for her to feel guilty, which is not helpful.
Choice B rationale:
While it is important to provide hope and information about the prognosis, this response does not address the mother’s immediate emotional distress and feelings of guilt. It focuses on the future rather than acknowledging her current emotional state.
Choice C rationale:
This response is empathetic and acknowledges the mother’s feelings. It provides emotional support and validates her experience, which is crucial in helping her cope with the situation.
Choice D rationale:
Telling the mother she did nothing wrong is important, but it does not fully address her emotional distress. It is a factual statement that may not provide the comfort and understanding she needs at this moment.
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.
