Which client must reschedule their blood donation?

A client who has an oral temperature of 37.8°C (100°F) must reschedule their blood donation because this temperature indicates a slight fever. Blood donation centers typically have health and safety criteria to ensure the well-being of both the donor and the recipients of the blood. A fever can be a sign of infection or illness, which raises concerns about the donor's health and the potential risk of transmitting infectious agents.

Acceptable donation criteria usually require that donors be free from any fever, cold symptoms, or recent illnesses to ensure that the process is safe. Therefore, the presence of a fever at the time of donation disqualifies the individual from donating blood until they have fully recovered and their temperature returns to a normal range.

In contrast, being Rh positive does not affect a client’s eligibility to donate blood; it simply pertains to blood type. A client weighing 50 kg (110 lbs) is typically eligible to donate 450 mL of blood, as this weight meets the minimum requirement for most blood donation regulations. Meanwhile, although there may be specific age-related guidelines, a 14-year-old can often donate blood if they meet other health criteria and with appropriate parental consent, depending on the regulations of the region or blood donation organization
