Which of the following statements is true regarding pilonidal cysts?

Polypharmacy in older adults increases the risk of adverse drug events, drug-drug interactions, falls, cognitive impairment, and hospitalizations. Safe prescribing requires regular medication review, reconciliation, and evaluation of appropriateness based on current clinical needs. Advanced practice nurses play a key role in minimizing unnecessary medications and optimizing therapeutic regimens. The goal is to improve safety while avoiding overprescribing, especially of high-risk medications.

Rationale:
A. Assessing medications for drug-drug interactions is essential in older adults because multiple concurrent medications increase the risk of harmful pharmacologic interactions. These interactions can alter drug metabolism, increase toxicity, or reduce therapeutic effectiveness. Regular review helps prevent adverse drug events and ensures safe pharmacotherapy.

B. Performing a thorough medication history and reconciliation ensures that all prescribed, over-the-counter, and herbal medications are accurately documented. This process helps identify duplications, omissions, and potentially inappropriate medications. It is a critical step in preventing errors during transitions of care and ongoing treatment.

C. Assessing for non-adherence, underuse, and inappropriate use of medications helps identify barriers to effective treatment in older adults. Patients may skip doses, take incorrect amounts, or continue unnecessary medications due to misunderstanding or cognitive decline. Addressing these issues improves therapeutic outcomes and reduces medication-related harm.

D. Routinely prescribing opioids for pain is inappropriate in older adults due to increased risks of sedation, respiratory depression, falls, constipation, and dependence. Opioids should only be used when necessary, at the lowest effective dose, and for the shortest duration possible. Non-opioid and non-pharmacologic pain management strategies are preferred as first-line approaches in most cases.

Lower extremity ulcers and skin changes can result from either arterial or venous circulation disorders, and distinguishing between them is essential for correct management. Chronic venous insufficiency occurs when venous valves fail, leading to venous hypertension, fluid leakage, and tissue changes in the lower legs. This condition commonly produces characteristic skin discoloration, edema, dermatitis, and medial ankle ulceration. Pulses are usually present because arterial flow is intact.

Rationale:
A. Chronic venous insufficiency is the most likely condition because it presents with normal or palpable peripheral pulses, brown hyperpigmentation from hemosiderin deposition, stasis dermatitis, and skin thickening (lipodermatosclerosis). Ulcers typically develop near the medial malleolus due to increased venous pressure and fluid leakage into surrounding tissues. The presence of a painless or mildly painful ulcer with intact pulses strongly supports venous rather than arterial pathology.

B. Chronic arterial insufficiency typically presents with diminished or absent pulses, cool extremities, pallor, and painful ischemic ulcers. These ulcers are usually located on distal areas such as toes or pressure points and have a “punched-out” appearance. The presence of +2 pedal pulses and brown pigmentation makes arterial insufficiency unlikely.

C. Acute arterial occlusion presents with sudden onset of the “6 Ps”: pain, pallor, pulselessness, paresthesia, paralysis, and poikilothermia. It is a medical emergency and does not present with chronic skin changes such as stasis dermatitis or hyperpigmentation. The chronic nature of symptoms in this case excludes acute arterial occlusion.

D. Compartment syndrome is characterized by severe pain out of proportion to injury, tense swollen compartments, and neurovascular compromise often following trauma or ischemia. It is an acute surgical emergency and does not present with chronic skin pigmentation changes or venous ulceration. The findings in this patient are consistent with a long-standing venous disorder rather than an acute compartment process.
