An individual with type AB blood will demonstrate the complete absence
of which of the following antigen sites?
A. A
B. B
C. H
D. None of the above
Verified Answer -D;
The A and B antigens are present on the red cells of an AB patient. H
antigen is a precursor to the ABO antigens.
Which of these could cause a sickling event?
A. Excessive intake of water
B. Fluctuations in temperature
C. Oxygen inhalation
D. Sedentary life-style
Verified Answer -B;
Abrupt change in temperature is one of the risk factors in which a sickling
event may occur.
Dehydration, hypoxia, and physical exertion, rather than excessive intake
of fluids, inhaling oxygen, and sedentary lifestyle, are all additional risk
factors in which sickling events may occur.
,Match each of the following definitions associated with heart disease and
heart failure to the term that it defines.
1. Congestive heart failure
2. Infarction
3. Ischemia
4. Angina
A. An inadequate blood supply that decreases availability of oxygen.
B. Chest pain caused by inadequate supply of oxygen to heart
myocardium.
C. An area of tissue death that occurs due to lack of oxygen.
D. A left ventricular dysfunction resulting from aging, hypertension,
atherosclerosis or muscle damage from an AMI or repeated AMIs.
Verified Answer -1. D
2. C
3. A
4. B
Which hemoglobin, when elevated, acts as a protection against sickling in
patients with HbS?
A. Hemoglobin A2
B. Hemoglobin C
C. Hemoglobin F
,D. Hemoglobin G
Verified Answer -C;
Hemoglobin F has a high affinity for oxygen. When Hb F is elevated, cells
containing Hb S are more oxygenated and do not sickle as readily as they
would if Hb F were not present or present in small quantities.
A refrigerator used to store whole blood must be able to maintain a
temperature in the ranges of:
A. 0 - 4 degrees Celsius
B. 2 - 4 degrees Celsius
C. 2 - 8 degrees Celsius

Verified Answer -D;
After collection all blood should be stored at 1 - 6oC, unless it is going to
be used as a source of platelets.
Acute obstructive epiglottitis, both in adults and children, is caused by the
bacterial species shown in this split screen photograph. The colonies
recovered on chocolate agar (upper frame) required both hematin and
NAD, (as shown by colony growth only between the X and V strips in the
lower frame). The most likely identification is:
A. Haemophilus parainfluenzae
B. Haemophilus influenzae
C. Haemophilus aphrophilus
D. Haemophilus haemolyticus
Verified Answer -B;
, Haemophilus influenzae is both X and V factor dependent for growth, and
is the most common cause of obstructive laryngitis and epiglottitis. H.
parainfluenzae is only V-factor dependent and causes only mild
pharyngitis, rarely obstructive in nature. H. aphrophilus can be part of the
normal upper respiratory flora in humans, does not cause pharyngitis, and
is not X or V-factor dependent for growth. Although H. haemolyticus is
both X and V-factor dependent, it is beta hemolytic on blood agar and is
generally considered non pathogenic.
Determine if each of the following is a cardiovascular risk marker or a
cardiovascular risk factor.
1. Smoking
2. Obesity
3. Low density lipoprotein (LDL)
4. Hypertension
5. Triglycerides
6. High sensitivity-C-reactive protein (hsCRP)
A. Cardiovascular risk factor
B. Cardiovascular risk marker
Verified Answer -1. A
2. A
3. B
4. A
5. B
6. B
