Drawbacks of blood cultures are
- A.
Specificity
- B.
Sensitivity
- C.
Slow growing organisms
- D.
None of the above
Correct Answer(s)
B. Sensitivity
C. Slow growing organismsExplanation
Blood cultures have certain drawbacks, including sensitivity and slow-growing organisms. Sensitivity refers to the ability of the blood culture to accurately detect the presence of microorganisms. If the sensitivity is low, it means that the blood culture may miss detecting certain infections, leading to false-negative results. Slow-growing organisms can also pose a challenge as they may take longer to grow in the culture, delaying the diagnosis and initiation of appropriate treatment. Therefore, both sensitivity and slow-growing organisms are valid drawbacks of blood cultures.Rate this question:

Blood Lactate levels correlate with mortality rates in septic shock and are related the development of organ failure and mortality following severe trauma.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Blood lactate levels are indeed correlated with mortality rates in septic shock and are also related to the development of organ failure and mortality following severe trauma. Elevated blood lactate levels indicate tissue hypoperfusion, which is a common characteristic of septic shock and severe trauma. When tissues do not receive enough oxygen, they switch to anaerobic metabolism, leading to the production of lactate. High levels of lactate in the blood indicate tissue hypoxia and are associated with poor outcomes and increased mortality rates in these conditions. Therefore, the statement is true.Rate this question:

It is recommended that you can use human serum or plasma collected in EDTA tubes
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is false. It is not recommended to use human serum or plasma collected in EDTA tubes. EDTA (ethylenediaminetetraacetic acid) is an anticoagulant that chelates calcium ions, which is necessary for blood clotting. Therefore, using EDTA tubes would prevent the blood from clotting, resulting in the collection of plasma rather than serum. Serum is obtained by allowing the blood to clot and then separating the liquid portion from the clotted cells.Rate this question:

It is recommended to retest PCT within __________________ hours if any concentrations < 2 ng/mL are obtained.
- A.
3-5
- B.
6-24
- C.
1-3
- D.
24-48
Correct Answer
B. 6-24Explanation
If any concentrations less than 2 ng/mL are obtained, it is recommended to retest PCT within 6-24 hours. This suggests that the initial test result may not be accurate or reliable, and a retest is necessary to confirm the PCT levels. Waiting for 6-24 hours allows enough time for any potential fluctuations in PCT levels to stabilize and provide a more accurate result.Rate this question:
