A nurse is caring for a patient with a wound. Which assessment data will be most relevant with regard to wound healing?

A. 4, 3, 2, 1 (Pulmonic → Tricuspid → Aortic → Mitral): This sequence incorrectly places the pulmonic valve first instead of the tricuspid.

B. 1, 3, 2, 4 (Mitral → Tricuspid → Aortic → Pulmonic): This sequence incorrectly starts with the mitral valve (left side of the heart), instead of the tricuspid (right side of the heart).

C. 3, 4, 1, 2 (Tricuspid → Pulmonic → Mitral → Aortic): Blood flow through heart valves follows this order:

1. Tricuspid Valve (Right atrium → Right ventricle)
2. Pulmonic Valve (Right ventricle → Pulmonary artery → Lungs)
3. Mitral Valve (Left atrium → Left ventricle)
4. Aortic Valve (Left ventricle → Aorta → Body)

D. 2, 4, 1, 3 (Aortic → Pulmonic → Mitral → Tricuspid): This sequence incorrectly places the aortic valve first, which is incorrect for blood flow through the heart.

A. Hypertension: Diphenhydramine (Benadryl) is an antihistamine that typically causes hypotension, not hypertension. It can have a mild vasodilatory effect, leading to a drop in blood pressure in some patients.

B. Constipation: While some antihistamines can cause mild gastrointestinal effects, constipation is not a primary adverse effect of diphenhydramine. Dry mouth and urinary retention are more common due to its anticholinergic properties.

C. Bradycardia: Diphenhydramine can sometimes cause tachycardia (increased heart rate), especially in elderly patients or those prone to cardiovascular effects. Bradycardia (slow heart rate) is not a usual adverse effect.

D. Sedation: Diphenhydramine is a first-generation antihistamine that crosses the blood-brain barrier and has a sedative effect by blocking histamine receptors in the central nervous system. It is commonly used as a sleep aid for this reason.
