The nurse determines that a male client has smoked 2 packs of cigarettes daily for the past 20 years. In calculating his smoking history, how many pack-years should be documented for this client? (Enter numeric value only.)

Rationale:
A. Assess the elasticity of the client's skin: Skin elasticity, or turgor, is useful for evaluating hydration status, especially in older adults. However, it does not address the client’s immediate complaints of nocturnal dyspnea, sweating, and tachycardia, which are potentially life-threatening signs of worsening heart failure.

B. Auscultate the client's breath sounds: Awakening with dyspnea, sweating, and a racing heartbeat are classic symptoms of paroxysmal nocturnal dyspnea, often seen in decompensated heart failure. Auscultating the lungs can quickly detect crackles or pulmonary congestion, providing critical information needed to prioritize urgent interventions.

C. Ask about any environmental allergies: Environmental allergies can cause nighttime breathing issues like nasal congestion, but the combination of cold sweats and tachycardia points more toward a cardiovascular cause rather than an allergic reaction, making this a less urgent assessment initially.

D. Measure the client's core temperature: While fever can indicate infection, it is less likely to explain the sudden onset of dyspnea and palpitations in a client with known heart failure. Addressing possible pulmonary congestion through breath sound assessment takes precedence to prevent further cardiac compromise.

Rationale:
A. Document thickened toe nails: Thickened toenails can be a sign of poor circulation associated with PVD, but documenting this alone does not provide critical information about current perfusion status. While important, it is less urgent compared to assessing the functionality of blood flow through distal pulses.

B. Palpate and document quality of distal pulses: Palpating distal pulses, such as dorsalis pedis and posterior tibial, is crucial to assess arterial blood flow to the extremities. In clients with PVD, weak or absent pulses can indicate worsening ischemia, making this assessment vital for early intervention and monitoring disease progression.

C. Measure ankle-brachial index (ABI): ABI is a non-invasive diagnostic test that measures the ratio of ankle to arm blood pressure to confirm PVD severity. It is a key diagnostic tool for PVD and provides objective data on the severity of arterial disease. However, in the context of a routine health assessment, palpating distal pulses offers immediate, albeit subjective, information about perfusion. While ABI is important, pulse assessment is often the initial and most readily available technique during a physical exam.

D. Measure and record dependent ankle edema: Dependent edema is more indicative of venous insufficiency rather than arterial PVD. Although documenting edema can assist in the overall vascular assessment, it does not directly evaluate arterial perfusion, which is the primary concern in PVD clients.
