Practice Test 1 CCRN (Pass CCRN)

Questions and Answers 100% Pass


What is vasogenic cerebral edema? - ANSWER✔✔-Vasogenic cerebral edema is an increase in

extracellular fluid caused by a breakdown of the blood-brain barrier with the resultant increase in

vascular permeability. This cerebral edema begins locally and becomes more generalized. Common

causes are trauma (including surgical trauma), tumors, hemorrhage, and abscesses


What ventilator parameter indicates fluid volume excess? - ANSWER✔✔-An A:a gradient greater than 10

mm Hg is a reflection of a diffusion defect. Note that the process of diffusion is between A (alveolus) and

(a) arterial blood. An increase in intraalveolar fluid dilutes and inactivates surfactant, causing alveolar

collapse (decreasing vital capacity) and decreases lung compliance. Peak inspiratory pressure increases

reflect a decrease in lung compliance


What does autonomy refer to? - ANSWER✔✔-The patient's right to make decisions for themselves


What does beneficence mean? - ANSWER✔✔-Obligation to do good


What does nonmaleficence mean? - ANSWER✔✔-Obligation to do no harm


What does fidelity mean? - ANSWER✔✔-the obligation to abide by agreements and responsibilities

Medicare patients. Payment is based on primary and secondary diagnosis, primary and secondary

procedures, age, and length of hospitalization


BNP is secreted in response to? - ANSWER✔✔-Ventricular wall stretch


What are omnious signs in a patient with status asthmaticus? - ANSWER✔✔-A normalization or increase

in the PaCO2. This patient is still tachypneic, and if ventilation is normal, PaCO2 should be decreased.

The other ominous sign in this patient would be absence of wheezing or rhonchi, because they would

indicate that ventilation is insufficient to cause these noises.


What problems arise from losses from the GI tract? - ANSWER✔✔-Any loss results in hypokalemia.

Vomiting results in loss of acidic contents, whereas losses below the pylorus result is alkalitic losses

leading to metabolic acidosis. Fluid is sequestered in the intestine leading to hypovolemia, which could

cause hypovolemic shock.


Actual problems are worse than potential problems!! - ANSWER✔✔-


How can you differentiate the cause of jaundice? - ANSWER✔✔-An increase in direct bilirubin is

associated with biliary obstruction because direct bilirubin is conjugated. An increase in indirect bilirubin

is associated with hepatic disease or excessive hemolysis because indirect bilirubin is unconjugated


What antihypertensive meds work best in African american patients? - ANSWER✔✔-African-Americans

do not respond well to angiotensin-converting enzyme inhibitors (e.g., captopril [Capoten]), but they do

respond well to an angiotensin II blocker (valsartan [Diovan]). Of the beta-blockers, labetalol works best.

Of the calcium channel blockers, diltiazem works best


What lab values define acute respiratory failure? - ANSWER✔✔-50-50!

What is the difference between an anaphylactic and anaphylactoid reaction? - ANSWER✔✔-

Anaphylactoid reaction is clinically indistinguishable from anaphylactic reaction but does not require

previous exposure to the antigen. Anaphylactoid reaction is not IgE mediated, and direct activation and

degranulation of mast cells are thought to be triggered by the complement system. Anaphylactic

reaction requires previous exposure to the antigen and is IgE mediated


Mitral stenosis is associated with what? - ANSWER✔✔-Pinkish discoloration of the cheeks. It is a diastolic

murmur


What murmur is associated with widened pulse pressure? - ANSWER✔✔-Aortic regurg


What murmur is associated with narrowed pulse pressure? - ANSWER✔✔-Mitral regurg


What lead changes are associated with left ventricle hyperthrophy? - ANSWER✔✔-Strain pattern in V5

and V6 (asymmetric T wave inversion)
