Question 1
What is accomplished by diffusion?
Correct Answer
Movement of molecules from an area of higher concentration to an area of lower concentration.
Question 2
Osmotic Diarrhea
Correct Answer
Caused by non-absorbable substances in the intestine drawing water into the bowel.
Question 3
BNP (B-type Natriuretic Peptide)
Correct Answer
A marker used to diagnose heart failure. A higher value indicates this.
Question 4
Pleural Effusion
Correct Answer
Accumulation of fluid in the pleural space around the lungs.
Causes: Severe pulmonary infection (PNA or TB), Congestive Heart failure, Cancer, Pulmonary Embolism
S/S: Dyspnea, Tachypnea, Sharp pleuritic chest pain, dullness to percussion, and diminished breath sounds on affected
side.

,Question 5
pH = 7.29 (Norm = 7.35-7.45)
Bicarb = 25 (Norm = 22-26)
CO2 = 55 (Norm = 35-45)
Which cause is consistent with these lab values?
Correct Answer
Respiratory Acidosis; Lungs are NOT ventilating correctly, retention of carbon dioxide = reduction of pH (Caused by
COPD, Infection, foreign body obstruction, and severe asthma.
Question 6
How does the Respiratory System compensate for acid-base disturbances?
Correct Answer
By changing the rate and depth of breathing.
Increasing = Expels CO2 to reduce acidity (compensates Metabolic Acidosis)
Decreasing = Retains CO2 to increase acidity (compensates Metabolic Alkalosis)
Question 7
One symptom of Acidosis?
Correct Answer
Rapid breathing aka Hyperventilation (body trying to get rid of the CO2)
Question 8
What describes a gene when the same allele is inherited from both parents?
Correct Answer
Homozygous (HH or hh)
Question 9
What statement describes the ICF (Intracellular Fluid) compartment?
Correct Answer
The fluid contained within the cells, making up about 2/3 of the body's total water content.
Question 10
Which two conditions will cause dehydration and increase water requirements?
Correct Answer
State of diminished water volume in the body. A deficit of intracellular fluid causes body cells to shrink.
Severe Diarrhea
Excessive Sweating
Vomiting

, Question 11
What are phagocytic cells?
Correct Answer
Part of innate immunity (inflammatory response)
Cells that engulf and digest pathogens and debris
EX) Macrophages and Neutrophils
Question 12
Turner's Syndrome (Short, webbed neck girl)
Correct Answer
Complete or partial missing X-chromosome in females
S/S: Hypothyroidism, Hypertension, Webbing of neck, amenorrhea, short stature, infertility, vission issues, and aortic valve
abnormalities.
Question 13
What are two symptoms of Huntington's Disease?
Correct Answer
Genetic defect of Huntington gene
Lack of control-involuntary motor symptoms
Cognitive decline
Depression
Dementia later in disease
Muscle spasticity
Speech/swallow difficulty
Question 14
Which three issues would children with ND-PAE exhibit (fetal alcohol syndrome)?
Correct Answer
Cognitive deficits, Behavioral problems, and Physical Abnormalities
Causes birth defects and developmental disabilities = Neurocognition, Self-regulation, and Adaptive functioning
Facial features, slow growth, delayed development, vision/hearing issues, and smaller head & brain.
Question 15
Grade 1 Sprain
Correct Answer
Mild stretching or slight tear of a ligament with little or no joint instability.
