During report the LPN is told that the patient has orthopnea due to valvular heart disease. The LPN expects to find the patient:

A. Discourage walking in order to limit pain: Physical inactivity promotes further vascular stasis and muscle atrophy in the lower extremities. While claudication causes discomfort, complete avoidance of movement prevents the development of collateral circulation. Reduced mobility exacerbates the underlying pathology of arterial insufficiency and impairs long-term functional outcomes.

B. Encourage extended periods of sitting or standing: Prolonged static positioning increases hydrostatic pressure and can worsen peripheral tissue perfusion. Dependency or stasis does not facilitate the arterial inflow required to oxygenate ischemic tissues. Frequent position changes are necessary to prevent localized pressure and maintain adequate circulatory flow.

C. Elevate his legs and arms above his heart when resting: This position hinders gravity-assisted arterial flow to the distal extremities, worsening ischemia. Unlike venous insufficiency, arterial disease requires the limbs to be maintained in a neutral or slightly dependent position. Elevation significantly reduces the perfusion pressure needed to reach peripheral tissues.

D. Encourage the client to engage in moderate amount of exercise: Structured walking programs stimulate the formation of collateral vessels to bypass occluded arteries. Physical activity improves oxygen extraction by the muscles and increases the pain-free walking distance. This intervention remains a cornerstone of conservative management for improving peripheral arterial circulation.

A. Hypothyroidism: While the client has a history of hypothyroidism, the clinical presentation of visual disturbances and profound bradycardia is not typical of a thyroid deficit. Low thyroid hormone levels usually present with weight gain, cold intolerance, and dry skin rather than greenish halos. The dose of 25 mcg is a standard replacement and does not explain the acute confusion or visual changes.

B. Digoxin toxicity: The combination of bradycardia with a heart rate of 44, greenish-yellow visual halos, and new-onset confusion are classic signs of digitalis overdose. Furosemide use often leads to hypokalemia, which significantly sensitizes the myocardium to the toxic effects of digoxin. A dose of 0.5 mg is also relatively high, increasing the risk of systemic accumulation and toxic side effects.

C. Glaucoma: This ocular condition causes increased intraocular pressure and can lead to vision loss or seeing halos around lights. However, glaucoma does not cause systemic symptoms like profound bradycardia, confusion, or gastrointestinal disturbances such as constipation. The visual symptoms in this case are a secondary manifestation of a systemic pharmacological toxicity rather than a primary eye disease.

D. Unstable angina: Unstable angina presents with crescendo chest pain at rest and is often associated with EKG changes or hemodynamic instability. It does not typically manifest with bradycardia, constipation, or the characteristic visual disturbances described in the stem. The client's symptoms point toward a metabolic or drug-induced etiology rather than acute coronary artery narrowing.
