NCLEXRN-06-001
After cardiac surgery, a client’s blood pressure measures 126/80 mm Hg. Nurse
... [Show More] Katrina determines
that mean arterial pressure (MAP) is which of the following?
A. 46 mm Hg
B. 80 mm Hg
C. 95 mm Hg
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 is incorrect according to the calculations.
Option B: 80 mmHg is inadequate according to the formula used in computation.
Option D: 90 mmHg is incorrect according to the computation using the formula of mean
arterial pressure.

Question Tag: chest pain
Question Category: Physiological Integrity, Reduction of Risk Potential
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
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.

Question Tag: coronary artery bypass graft
Question Category: Physiological Integrity, Physiological Adaptation
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)
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.

Question Tag: idiopathic thrombocytopenic purpura
Question Category: Physiological Integrity, Pharmacological and Parenteral Therapies
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
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.
