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
Option A: 46 mmHg isaccording to the calculations.
Option B: 80 mmHg is inadequate according to the formula used in the
computation.
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.
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.
Option B: Prothrombin time, partial thromboplastin time, fibrinogen
and fibrin split products are measured to verify bleeding dyscrasias.
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)
, 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.
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.
Option C: Although DIC causes platelet aggregation and bleeding, it is
common in a client after revascularization surgery.
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.
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).
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.
Option A: Allogeneic transplant is between two humans,
Option B: Autologous is a transplant from the same individual.
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
