Questions)

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
Incorrect
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 is incorrect according to the calculations.
 Option B: 80 mmHg is inadequate according to the formula used
in the computation.
 Option D: 90 mmHg is incorrect according to the computation
using the formula of mean arterial pressure.
2. 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?


 A. Cardiac monitor, oxygen, creatine kinase and lactate
dehydrogenase levels

, B. Prothrombin time, partial thromboplastin time, fibrinogen and
fibrin split product values

 C. Electrocardiogram, complete blood count, testing for
occult blood, comprehensive serum metabolic panel

 D. Electroencephalogram, alkaline phosphatase, and aspartate
aminotransferase levels, basic serum metabolic panel
Incorrect
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. 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?


 A. Pancytopenia

 B. Idiopathic thrombocytopenic purpura (ITP)

 C. Disseminated intravascular coagulation (DIC)

 D. Heparin-associated thrombosis and thrombocytopenia
(HATT)
Incorrect

, 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. 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)?


 A. Acetylsalicylic acid (ASA)

 B. Corticosteroids

 C. Methotrexate

 D. Vitamin K
Incorrect
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.
 Option D: Vitamin K is used to treat an excessive anticoagulate
state from warfarin overload.
5. 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?

,  A. Allogeneic

 B. Autologous

 C. Syngeneic

 D. Xenogeneic
Incorrect
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. 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?


 A. Release of Calcium

 B. Release of tissue thromboplastin

 C. Conversion of factors XII to factor XIIa

 D. Conversion of factor VIII to factor VIIIa
Incorrect
Correct Answer: B. Release of tissue thromboplastin
Tissue thromboplastin is released when damaged tissue comes in
contact with clotting factors.
 Option A: Calcium is released to assist the conversion of factors
X to Xa.
 Option C: Conversion of factors XII to XIIa are part of the intrinsic
pathway.
 Option D: Conversion factors VIII to VIIIa are part of the intrinsic
pathway.
7. 7. Question
Instructions for a client with systemic lupus erythematosus (SLE) would
include information about which of the following blood dyscrasias?
