A client is ordered Lovenox for DVT prophylaxis. The physician orders 1.2 mg/kg subcutaneously once daily to be administered. The client weighs 185 pounds. Available is Lovenox 80 mg/0.8 mL. How many milliliters will the nurse administer? Round to the nearest tenth, if necessary, and label your answer.

A. "Since you are older, how bad is your eyesight?": This question is age-biased and vague, focusing on chronological age rather than functional ability. It does not provide concrete information about how vision impairment affects daily self-care activities, making it less useful for planning care.

B. "Are you able to read the menu to order your own meals?": This question directly assesses the patient’s functional vision in a practical context, highlighting how visual alterations impact an essential self-care activity—making choices about nutrition. It provides actionable information for the nurse to identify needs for assistance or adaptive strategies.

C. "What recreational activities do you enjoy?": While this question explores lifestyle and interests, it does not specifically identify limitations in self-care caused by vision problems. It may inform quality-of-life interventions but is secondary to evaluating functional deficits.

D. "Do you read more than one book in a year?": This question assesses reading habits rather than the patient’s ability to perform daily self-care tasks. It does not accurately capture functional impairment or its effect on independence, limiting its relevance for nursing assessment of visual deficits.

A. Notify the physician immediately of this unexpected finding: While loss of suction should be reported if it cannot be corrected, immediate notification is not the first action. The nurse should first attempt standard troubleshooting to re-establish suction, as this is often a correctable issue without needing urgent physician intervention.

B. Allow gravity to assist with draining by repositioning the drain to a position lower than the client: Positioning the drain lower may facilitate passive drainage, but it does not restore the negative pressure needed for the Jackson-Pratt drain to function effectively. Relying solely on gravity can lead to fluid accumulation and increase the risk of infection.

C. Re-establish the negative pressure by opening the valve and decompressing the bulb: The Jackson-Pratt drain relies on negative suction to remove fluid from the wound site. If suction is lost, the nurse should compress the bulb after emptying it and closing the valve to restore negative pressure, ensuring continued drainage and reducing the risk of hematoma, or infection.

D. Switch the client's drain to a Hemovac drain to improve suction: Replacing the drain is not the first-line action. Hemovac drains are a different device, and switching requires a physician’s order. The priority is to troubleshoot and restore the function of the existing Jackson-Pratt drain before considering device replacement.
