The healthcare provider prescribes dalteparin 200 units/kg subcutaneously once day for a client who weighs 154 pounds. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.6"]
Calculation:
- Convert the client's weight from pounds (lb) to kilograms (kg).
The client's weight is 154 lb.
Client weight (kg) = 154 lb/2.2 lb/kg
= 70 kg.
- Calculate the total dose to be administered (units).
The ordered dose is 200 units/kg.
Total dose (units) = 200 units/kg×70 kg
= 14,000 units.
- Calculate the volume to administer in milliliters (mL).
Available concentration is 25,000 units/mL.
Volume (mL) = Total dose (units)/Available concentration (units/mL)
= 14,000 units/25,000 units/mL
= 0.56 mL.
- Round the answer to the nearest tenth.
= 0.6 mL.

Correct Answer is D
Explanation
A. Palpate flank area: Flank assessment may help detect kidney tenderness or infection but is not the primary focus for routine suprapubic catheter care unless complications are suspected.
B. Assess perineal area: The suprapubic catheter bypasses the perineal route, so routine perineal assessment is less critical for catheter management, though general hygiene remains important.
C. Measure abdominal girth: Abdominal girth measurement is useful for detecting ascites or abdominal distention but is not directly relevant to monitoring a suprapubic catheter.
D. Observe insertion site: Regular inspection of the catheter insertion site is essential to detect signs of infection, leakage, irritation, or improper placement. This assessment helps ensure catheter function and prevents complications, making it the priority during home visits.
Correct Answer is D
Explanation
A. Offer to discuss the client's health status with each of the adult children: While involving family in discussions is important, the immediate question from the spouse is about recognizing signs of imminent death. Directly explaining the physiological changes is more appropriate at this moment.
B. Reassure the spouse that the healthcare provider (HCP) will notify when to call the children: Waiting for the HCP to give a signal does not provide the spouse with the knowledge they are seeking. It may delay preparation and increase anxiety during the final hours.
C. Gather information regarding how long it will take for the children to arrive: While logistical planning is helpful, it does not address the spouse’s question about recognizing imminent death and understanding what to expect.
D. Explain that the client will start to lose consciousness and the body systems will slow down: Providing clear, compassionate information about the expected signs of dying helps the spouse recognize that death is near, allows family members to prepare emotionally, and facilitates meaningful final interactions with the client.
