87. A phlebotomist is performing a brief examination to determine whether a potential blood donor is in good condition to donate blood. Which of the following findings will exclude the patient from blood donation?
Answer: A
Body temperature in excess of 37.5° C (99.5° F)
A body temperature exceeding 37.5° C (99.5° F) indicates a fever, which is a common exclusion criterion for blood donation as it may suggest an underlying infection or illness.
A) Body temperature in excess of 37.5° C (99.5° F)
This option is correct because elevated body temperature is a clear indicator that the individual may not be in optimal health for donating blood. A fever can compromise the safety of both the donor and the recipients of the blood.
B) Systolic blood pressure in excess of 150 mm Hg
While elevated blood pressure can be concerning, it is not an automatic exclusion criterion for blood donation. Many individuals with high blood pressure can still donate blood if their condition is managed and stable.
C) Pulse between 105/min and 125/min
A pulse rate in this range is considered elevated and may raise concerns about the donor's cardiovascular health. However, it is not an absolute disqualifier and can be acceptable depending on the individual's overall health status.
D) Respiratory rate 14/min
A respiratory rate of 14 breaths per minute falls within the normal range for adults. Therefore, this finding does not exclude a patient from donating blood and is not a cause for concern in the context of blood donation.
Conclusion
In summary, a body temperature exceeding 37.5° C (99.5° F) is the only finding among the options that definitively excludes a potential donor from blood donation due to the risk of infection. Other options, while they may indicate health issues, do not meet the strict exclusion criteria established for blood donation.
