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 D
Explanation
Choice A reason: The nurse cannot force the client to take medication against their will, even if it is a controlled substance.
Choice B reason: Crediting the medication back and placing it in the client's medication box is not appropriate as the medication has already been removed from the unit dose wrapper.
Choice C reason: Keeping the medication to see if the client will want to take it later is not safe practice as it could lead to medication errors or misuse.
Choice D reason: The nurse should dispose of the medication properly, and having another nurse witness the disposal is a standard procedure to ensure that controlled substances are accounted for.
Correct Answer is B
Explanation
Choice A reason: While medication shortages can occur, this is not the typical reason for delivering a partial supply of medication for home health care.
Choice B reason: Daptomycin is an antibiotic that has a limited shelf life after it is mixed or reconstituted. This is why pharmacies often deliver only a portion of the doses to ensure the medication remains effective.
Choice C reason: Notifying the healthcare provider is necessary if there is a discrepancy in medication delivery that cannot be explained by standard pharmacy practices.
Choice D reason: Although instructions for medication administration may change, this is not the usual reason for a pharmacy to deliver a partial supply of medication.
