The nurse is preparing a client for coronary artery bypass surgery. What vessel does the nurse know is most commonly used for grafting?

A. An angiotensin receptor blocker (ARB): ARBs, such as losartan or valsartan, block the angiotensin II receptor but are pharmacologically distinct from ACE inhibitors. Captopril is not classified in this drug group.
B. A calcium channel blocker: Calcium channel blockers, such as amlodipine, reduce blood pressure by relaxing vascular smooth muscle. Captopril does not function through calcium channel modulation and is unrelated to this class.
C. An angiotensin converting enzyme inhibitor (ACE) inhibitor: Captopril is an ACE inhibitor that lowers blood pressure and reduces afterload by inhibiting the conversion of angiotensin I to angiotensin II. It is commonly prescribed for heart failure management to improve cardiac output and prevent fluid overload.
D. A thiazide diuretic: Thiazide diuretics like hydrochlorothiazide promote sodium and water excretion. They help manage hypertension but work differently from captopril, which targets the renin-angiotensin-aldosterone system.

A. The client has pneumonia in the bases: Crackles in the lung bases can suggest pneumonia; however, this finding alone does not confirm a diagnosis. Diagnosis requires clinical correlation with imaging findings such as consolidation or opacities and possibly labs. The physical deformity of the chest (sternal depression) is unrelated to the presence of pneumonia.
B. The client has chronic respiratory disease: While dyspnea and crackles may be seen in chronic respiratory diseases like COPD, the inspection finding of a depressed sternum is not characteristic of these conditions. An illness occurring for two days is also acute and cannot be termed chronic. Documenting a structural deformity based on inspection is more accurate than assuming a chronic disease.
C. The client has a funnel chest: Funnel chest, or pectus excavatum, is a deformity marked by a sunken appearance of the sternum, often more noticeable on inspiration. This is an accurate inspection-based finding that the nurse should document, separate from the respiratory symptoms.
D. The client needs a cough suppressant: A cough suppressant is a potential treatment option for symptomatic relief, but this does not relate to the inspection finding. The nurse’s role at this point is assessment and documentation, not treatment decisions based solely on visual inspection.
