Which physical examination result is a cause for rejecting a whole-blood donor?

• A. Weight of 105 lb
• B. Pulse of 75
• C. Temperature of 99.3° F
• D. Diastolic pressure of 110 mm Hg

Answer: (D)

A diastolic pressure of 110 mm Hg is a critical factor that leads to the rejection of a whole-blood donor due to hypertension. Blood donation requires that the donor be in optimal health to ensure both their safety and the safety of the blood supply. A diastolic pressure that exceeds the typical upper limit of normal (less than 90 mm Hg, generally) indicates potential cardiovascular issues, thus posing a risk for the donor during the donation procedure. Hypertension may lead to complications like fainting or additional cardiovascular stress during the donation, so a reading of 110 mm Hg would be deemed unacceptable. In contrast, a weight of 105 lb might pass certain donor criteria, depending on the guidelines of the donation facility, as it typically meets minimum weight requirements. A pulse of 75 is considered normal and stable, indicative of a healthy cardiovascular status. A temperature of 99.3° F, while elevated, may not necessarily disqualify a donor immediately; donors are generally eligible with temperatures under 100.5° F unless there are accompanying symptoms suggesting illness.
