1. 1. Question
After cardiac surgery, a client’s blood pressure measures 126/80
mm Hg. Nurse Katrina determines that mean arterial pressure
(MAP) is which of the following?
o A. 46 mm Hg
o B. 80 mm Hg
o C. 95 mm Hg
o D. 90 mm Hg
Correct Answer: C. 95 mm Hg
Use the following formula to calculate MAP
MAP = systolic + 2 (diastolic)
MAP = 126 mm Hg + 2 (80 mm Hg)
MAP = 286 mm Hg
MAP = 95 mm Hg
o Option A: 46 mmHg is according to the calculations.
o Option B: 80 mmHg is inadequate according to the
formula used in the computation.
o Option D: 90 mmHg is according to the computation
using the formula of mean arterial pressure.
• 2. Question
A female client arrives at the emergency department with chest
and stomach pain and a report of black tarry stool for several
months. Which of the following orders should the nurse Oliver
anticipate?
o A. Cardiac monitor, oxygen, creatine kinase and lactate
dehydrogenase levels

o B. Prothrombin time, partial thromboplastin time,
fibrinogen and fibrin split product values
o C. Electrocardiogram, complete blood count,
testing for occult blood, comprehensive serum
metabolic panel
o D. Electroencephalogram, alkaline phosphatase, and
aspartate aminotransferase levels, basic serum metabolic
panel
Correct Answer: C. Electrocardiogram, complete blood
count, testing for occult blood, comprehensive serum
metabolic panel.
An electrocardiogram evaluates the complaints of chest pain,
laboratory tests determine anemia, and the stool test for occult
blood determines blood in the stool.
o Option A: Cardiac monitoring, oxygen, and creatine
kinase, and lactate dehydrogenase levels are
appropriate for a cardiac primary problem. A basic
metabolic panel and alkaline phosphatase and
aspartate aminotransferase levels assess liver
function.
o Option B: Prothrombin time, partial thromboplastin
time, fibrinogen and fibrin split products are measured
to verify bleeding dyscrasias.
o Option D: An electroencephalogram evaluates brain
electrical activity.
• 3. Question
Olivia had coronary artery bypass graft (CABG) surgery 3 days
ago. Which of the following conditions is suspected by the nurse
when a decrease in platelet count from 230,000 ul to 5,000 ul is
noted?
o A. Pancytopenia
o B. Idiopathic thrombocytopenic purpura (ITP)
o C. Disseminated intravascular coagulation (DIC)

N
o D. Heparin-associated thrombosis and
thrombocytopenia (HATT)
Correct Answer: D. Heparin-associated thrombosis and
thrombocytopenia (HATT)
HATT may occur after CABG surgery due to heparin use during
surgery.
o Option B: ITP is a bleeding condition of unknown
cause in which the blood fails to clot adequately
because of a low circulating platelet count and a
shortened platelet lifespan.
o Option C: Although DIC causes platelet aggregation
and bleeding, it is common in a client after
revascularization surgery.
o Option A: Pancytopenia is a reduction in all blood
cells.
• 4. Question
Which of the following drugs would be ordered by the physician
to improve the platelet count in a male client with idiopathic
thrombocytopenic purpura (ITP)?
o A. Acetylsalicylic acid (ASA)
o B. Corticosteroids
o C. Methotrexate
o D. Vitamin K
Correct Answer: B. Corticosteroids
Corticosteroid therapy can decrease antibody production and
phagocytosis of the antibody-coated platelets, retaining more
functioning platelets.
o Option A: ASA blocks prostaglandin synthesis.
Inhibition of COX-1 results in the inhibition of platelet
aggregation for about 7-10 days (average platelet
lifespan).
o Option C: Methotrexate inhibits enzymes responsible
for nucleotide synthesis which prevents cell division

and leads to anti-inflammatory actions. It causes

thrombocytopenia.
o Option D: Vitamin K is used to treat an excessive
anticoagulate state from warfarin overload.
• 5. Question
A female client is scheduled to receive a heart valve replacement
with a porcine valve. Which of the following types of transplant is
this?
o A. Allogeneic
o B. Autologous
o C. Syngeneic
o D. Xenogeneic
Correct Answer: D. Xenogeneic
A xenogeneic transplant is between a human and another
species.
o Option A: Allogeneic transplant is between two
humans,
o Option B: Autologous is a transplant from the same
individual.
o Option C: A syngeneic transplant is between identical
twins.
• 6. Question
Marco falls off his bicycle and injures his ankle. Which of the
following actions shows the initial response to the injury in the
extrinsic pathway?
o A. Release of Calcium
o B. Release of tissue thromboplastin
o C. Conversion of factors XII to factor XIIa
o D. Conversion of factor VIII to factor VIIIa
