  Transport media are required for throat culture swabs but not for rapid strep tests.

  B. False

  Correct Answer: A

• Question 553:

  High-sensitivity C-reactive protein (hs-CRP) is used as an aid in the diagnosis and treatment of cardiovascular disease (CVD). At low levels, it can detect those at risk for cardiac heart disease. At high levels in those with no history of heart disease, it indicates a high risk for acute myocardial infarction (AMI), stroke, or peripheral vascular disease. For patients with acute coronary syndrome (ACS) or stable coronary disease, hs-CRP is used to predict future coronary events.

  Ranges of hs-CRP in prediction of risk for CVD are:

  <1.0

  mg/L Low CVD risk 1.0-3.0 mg/L Average risk for CVD >3.0 mg/L High risk for future CVD If results are >10.0 mg/L, the patient should be evaluated for an acute inflammatory condition. Chemistry A high-sensitivity C-reactive protein (hs-CRP) test result of 5 mg/L (normal = < 1 mg/L) may indicate which of the following?

  A.

  Low risk for cardiovascular disease (CVD)

  B.

  High risk for future CVD

  C.

  Acute inflammatory condition

  Correct Answer: B

• Question 557:

  The production of long, tapered phialides is one of the key identifying features of Trichoderma species. In contrast, Penicillium species, produce phialides with blunt ends.

  

  The phialides of Beauveria species are geniculate, forming a zig-zag pattern.

  Correct Answer: A
