The nurse observes that a client with Parkinson's disease (PD) has a mask like face. Which follow up assessment is most important for the nurse to implement?

A. Teach client to use pursed lip breathing when episodes occur: Pursed lip breathing can help improve ventilation and reduce air trapping during asthma exacerbations, but it is more of a supportive technique than a preventive one. It does not address the root cause of exercise-induced bronchoconstriction, which often requires pre-treatment strategies.

B. Review the client's routine asthma management prescriptions: While it's important to review long-term asthma management, exercise-induced bronchospasm requires pre-exercise interventions. The client may be compliant with their daily medications, but still experience exercise-induced asthma.

C. Assess client for signs and symptoms of upper airway infection: Respiratory infections can exacerbate asthma, but the client’s symptoms are specifically linked to exercise. Investigating an infection may be warranted if symptoms were persistent or unrelated to exertion, but it's not the most immediate or relevant action.

D. Determine if the client is using an inhaler before exercising: Short-acting beta-agonists (SABAs), such as albuterol, are commonly prescribed prophylactically for use prior to exercise to prevent exercise-induced bronchospasm. Confirming proper inhaler use before activity directly targets the client's concern and is a key step in asthma self-management.

A. Pale skin: Pallor is a classic sign of reduced peripheral circulation and suggests inadequate oxygenated blood flow to the tissues. In the context of amputation and peripheral vascular disease, pale skin near the residual limb may reflect compromised perfusion and should be closely monitored for signs of ischemia or delayed healing.
B. Capillary refill: Delayed capillary refill (greater than 2 seconds) is an indicator of impaired tissue perfusion and poor blood flow to the periphery. A capillary refill time of 4 seconds is significantly prolonged indicating delayed peripheral circulation which is a key marker of ineffective peripheral tissue perfusion.
C. Blood pressure: The client’s blood pressure is within normal limits (126/84 mm Hg) and does not suggest systemic hypoperfusion. While hypotension can impact tissue perfusion, this stable BP supports adequate central circulation and is not directly indicative of peripheral perfusion issues.
D. Oxygen saturation: An oxygen saturation of 95% on room air reflects adequate oxygenation at the systemic level. Peripheral tissue perfusion issues are localized and may not always be evident in systemic oxygen saturation readings unless accompanied by widespread circulatory compromise.
E. Edema: The presence of edema around the incision may indicate impaired lymphatic or venous return, which can hinder oxygen and nutrient delivery to tissues. Edema is a common sign of ineffective peripheral perfusion. Localized swelling around the incision can impair oxygen and nutrient exchange in the tissues by increasing interstitial pressure.
