The nurse is preparing to administer lorazepam 1.5 mg IV to an anxious preoperative client. The medication is available in a 2 mg/mL vial. Which action should the nurse perform with the remainder of the medication?
Place the vial with the remainder of the medication into a locked drawer.
Withdraw the medication into a syringe and label it with the client’s name.
Ask another nurse to witness the medication being discarded.
Throw the vial into the trash in the presence of another nurse.
The Correct Answer is C
Choice A rationale
Placing the vial with the remainder of the medication into a locked drawer is not appropriate because it does not ensure proper documentation and accountability for the remaining medication. Controlled substances require strict documentation and disposal procedures.
Choice B rationale
Withdrawing the medication into a syringe and labeling it with the client’s name is not necessary and can lead to errors or contamination. The medication should not be stored for future use in this manner.
Choice C rationale
Asking another nurse to witness the medication being discarded is the correct action. This ensures proper documentation, accountability, and compliance with regulations for the disposal of unused or remaining medications, especially controlled substances.
Choice D rationale
Throwing the vial into the trash in the presence of another nurse is not appropriate. It does not ensure proper documentation, accountability, or safe disposal of the remaining medication. Controlled substances require specific disposal procedures to prevent misuse or diversion.

Correct Answer is B
Explanation
Choice A rationale
Capillary refill time is 2 seconds. A capillary refill time of 2 seconds is within normal limits and is unlikely to affect the accuracy of the pulse oximetry reading.
Choice B rationale
2+ edema of fingers and hands. Edema can interfere with the accuracy of pulse oximetry readings by affecting the perfusion of the area where the sensor is placed. This can lead to falsely low oxygen saturation readings.
Choice C rationale
Radial pulse volume is 3+. A strong radial pulse indicates good peripheral perfusion, which should not negatively impact the accuracy of the pulse oximetry reading.
Choice D rationale
Blood pressure is 142/88 mm Hg. While elevated blood pressure can have various effects on the body, it is not likely to directly affect the accuracy of a pulse oximetry reading.
Correct Answer is C
Explanation
Choice A rationale
A urine specific gravity of 1.015 is within the normal range and does not indicate dehydration. Dehydration typically results in a higher urine specific gravity due to the concentration of solutes in the urine.
Choice B rationale
A urine specific gravity of 1.005 is lower than normal and indicates dilute urine, which is not consistent with dehydration. Dehydration would result in more concentrated urine with a higher specific gravity.
Choice C rationale
A urine specific gravity of 1.035 indicates highly concentrated urine, which is consistent with dehydration. When a client has a history of vomiting and diarrhea, they are likely to be dehydrated, leading to a higher urine specific gravity.
Choice D rationale
A urine specific gravity of 1.025 is slightly higher than normal but not as high as 1.035. While it may indicate some level of concentration, it is not as indicative of severe dehydration as a specific gravity of 1.035.
