The nurse is planning care for a client who is unconscious and immobile. Which physiological problem may result from cardiovascular changes for this client?

A. Leave the pill as requested: Leaving medications at the bedside is a violation of safety standards and institutional policy. It poses a significant risk for medication errors, accidental ingestion by others, or the client forgetting to take it. The nurse must personally witness the administration to ensure the "right patient" and "right dose" are confirmed.

B. Have the client take it at this time or not at all: This approach is unnecessarily rigid and ignores the principles of patient-centered care and autonomy. Sleep medications are most effective when the patient is physiologically and psychologically prepared for rest. Forcing immediate ingestion may lead to poor therapeutic outcomes or patient dissatisfaction with their care.

C. Tell the client to call the nurse when ready for the medication: This response respects the client's autonomy while adhering to strict medication safety protocols. It ensures the nurse is present to document the exact time of administration and monitor for immediate adverse effects. This practice maintains the chain of custody for controlled substances or sedative-hypnotics.

D. Leave the pill as requested and check back in half an hour to be sure that the pill the medication was taken: Even with a follow-up check, the nurse cannot definitively verify that the medication was swallowed rather than lost or hidden. Bedside storage remains a high-risk practice that circumvents required safety checks. Direct observation is the only acceptable method for confirming medication adherence.

A. Edema: Venous insufficiency leads to poor return of blood from the lower extremities, causing fluid accumulation in the interstitial tissues. This manifests as leg swelling (edema), which is a hallmark of venous disease.

B. Pale wound bed: A pale wound bed is more characteristic of arterial ulcers, which result from poor oxygenation and perfusion. Venous ulcers usually have a ruddy, beefy red wound bed due to adequate arterial inflow but impaired venous return.

C. Itchy dry scaly skin: Chronic venous stasis causes skin changes such as stasis dermatitis. Patients often report itching, dryness, and scaling due to impaired circulation and inflammatory changes in the skin.

D. Large amount of drainage: Venous ulcers typically produce copious exudate because of high hydrostatic pressure in the veins, which forces fluid out into the wound bed. This is one of the distinguishing features compared to arterial ulcers, which are usually dry.

E. Wound edges surrounded by calloused tissue: Calloused wound edges are more typical of neuropathic/diabetic ulcers, especially on pressure points of the foot. Venous ulcers usually have irregular, shallow edges without callus formation.

F. Hyperpigmentation of the skin surrounding the ulcerated area: Long-standing venous hypertension causes red blood cells to leak into surrounding tissues. Breakdown of hemoglobin deposits hemosiderin, leading to brownish discoloration (hyperpigmentation) around the ulcer site.
