Exam Questions and Correct Answers |
New Update
What is accomplished by diffusion? - 🧠 ANSWER ✔✔Movement of
molecules from an area of higher concentration to an area of lower
concentration.
Osmotic Diarrhea - 🧠 ANSWER ✔✔Caused by non-absorbable substances
in the intestine drawing water into the bowel.
BNP (B-type Natriuretic Peptide) - 🧠 ANSWER ✔✔A marker used to
diagnose heart failure. A higher value indicates this.
,Pleural Effusion - 🧠 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.
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? - 🧠 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.
How does the Respiratory System compensate for acid-base disturbances?
- 🧠 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)
One symptom of Acidosis? - 🧠 ANSWER ✔✔Rapid breathing aka
Hyperventilation (body trying to get rid of the CO2)
What describes a gene when the same allele is inherited from both
parents? - 🧠 ANSWER ✔✔Homozygous (HH or hh)
What statement describes the ICF (Intracellular Fluid) compartment? - 🧠
ANSWER ✔✔The fluid contained within the cells, making up about 2/3 of
the body's total water content.
Which two conditions will cause dehydration and increase water
requirements? - 🧠 ANSWER ✔✔State of diminished water volume in the
body. A deficit of intracellular fluid causes body cells to shrink.
Severe Diarrhea
Excessive Sweating
Vomiting
What are phagocytic cells? - 🧠 ANSWER ✔✔Part of innate immunity
(inflammatory response)

EX) Macrophages and Neutrophils
Turner's Syndrome (Short, webbed neck girl) - 🧠 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.
What are two symptoms of Huntington's Disease? - 🧠 ANSWER
✔✔Genetic defect of Huntington gene
Lack of control-involuntary motor symptoms
Cognitive decline
Depression
Dementia later in disease
Muscle spasticity
Speech/swallow difficulty
Which three issues would children with ND-PAE exhibit (fetal alcohol
syndrome)? - 🧠 ANSWER ✔✔Cognitive deficits, Behavioral problems, and
Physical Abnormalities
