Which lab value is a reliable indicator of bone marrow suppression in a patient receiving chemotherapy?
Total protein level
Serum potassium level
Erythrocyte sedimentation rate (ESR)
Platelet count
The Correct Answer is D
A. Total protein level. Total protein level does not directly indicate bone marrow suppression.
B. Serum potassium level. Serum potassium level reflects electrolyte balance but is not specific for bone marrow suppression.
C. Erythrocyte sedimentation rate (ESR). ESR can indicate inflammation but is not a reliable indicator of bone marrow suppression.
D. Platelet count. Platelet count is a reliable indicator of bone marrow suppression because chemotherapy can significantly reduce platelet production, leading to thrombocytopenia.

Correct Answer is D
Explanation
A. Hemoglobin A1C level is not typically assessed in patients with sickle cell anemia as it is primarily used to monitor long-term blood sugar control in individuals with diabetes mellitus.
B. While appetite may be relevant to the overall health of the patient, it is not the priority assessment in a patient with sickle cell anemia.
C. Reflexes may be assessed during the physical examination, but they are not the priority assessment in a patient with sickle cell anemia.
D. Vaccination history is the priority assessment in a patient with sickle cell anemia because individuals with sickle cell disease are at increased risk of infections, particularly from
encapsulated bacteria. Therefore, ensuring that the patient is up-to-date on vaccinations, including pneumococcal and meningococcal vaccines, is crucial for preventing serious infections.
Correct Answer is A
Explanation
A. The use of latex condoms. Latex condoms are highly effective in reducing the transmission of many STIs when used consistently and correctly.
B. Avoiding sexual contact if a partner is known to have an STI. While avoiding contact with an infected partner is important, many people may not know if their partner is infected, and this does not provide protection against unknown infections.
C. Vaccination against vaccine-preventable STIs. While vaccination is important (e.g., for HPV and hepatitis B), it does not protect against all STIs.
D. Limiting sexual partners. Limiting sexual partners can reduce risk but does not eliminate the risk of STIs if other protective measures are not used.
