Questions with Correct Answers
Low pH - Answer-Acidic
High pH - Answer-Alkaline
Normal pH ranges for the body - Answer-7.35-7.45 pH
If the pH is high with a low concentration of H+? - Answer-Then the body wants to
reabsorb H+ and eliminate HCO3 (bicarbonate)
High hydrogen (acidosis) and your PH is low? - Answer-The body wants hydrogen
elimination and the bicarb reabsorbed
Respiratory Acidosis - Answer-pH <7.35
**high PaCO2
normal HCO3-
Respiratory Alkalosis - Answer-pH >7.45
---Low--- PaCO2
normal HCO3-
Normal RBC count - Answer-4.2-5.2 million/mm3
Mature platelet - Answer-Thrombocyte
If you have too many platelets you are at risk for - Answer-blood clot
Normal platelet count - Answer-100,000-400,000/mm3
*** A patient with a 20,000 platelet count would be at risk for a bleed.
Erythrocytes - Answer-RBCs produced in the bone marrow. Normal survival is 85-90
days (3 months)
Reticulocyte count - Answer-Almost matured red blood cell count that it is in the bone
marrow. This is how you can measure the production of blood cells in the bone marrow.
Normal Hemoglobin count - Answer-13-18 g/dl (male); 12-16 g/dl (female)
Normal Hematocrit count - Answer-40-50% (male); 38%-48% (female)
Normal WBC count - Answer-5,000-10,000/mm3
,Hemoglobin is defined as... - Answer-A molecule that is bound to a RBC that binds to
oxygen and carries it to the tissues.
***Think Oxygen Saturation.
What WBCs are granulocytes? - Answer-Neutrophils, Eosinophils, & Basophils
If you have an infection what cell is going to go up? - Answer-WBCs (particularly
granulocytes in the neutrophil area)
What are band neutrophils? - Answer-They are rapidly used in infection. They are
slightly immature neutrophils.
"Shift to the left" means? - Answer-The band neutrophils are being put out before they
are matured and they are being eaten up.
CBC - Answer-Complete Blood Count for a Peripheral Blood Smear
Sodium - Answer-136-144 mEq/L
Chloride - Answer-101-111 mEq/L
Potassium - Answer-3.7-5.2 mEq/L
Low potassium and high potassium can cause - Answer-causes cardiac arythmias
If someone is dehydrated they would have... - Answer-High sodium
Chloride will - Answer-follow sodium levels
Blood Urea Nitrogen BUN indicates - Answer-7-20 mg/dL
How much nitrogen is in the blood and it tells you how the kidneys are functioning. If
nitrogen is high it is a sign of kidney failure.
,Glucose - Answer-70-100 mg/dL
Tells us how much sugar is readily available in the blood.
Bicarbonate (HCO3) - Answer-20-29 mmol/L
Tells us if the patient is in Metabolic Acidosis and Alkalosis.
Albumin - Answer-3.9-5.0 g/dL
Has potential pulling power and influences fluid in the extracellular and intracellular
space.
If Albumin is low then the patient is unable to excrete fluids and can result in ascites.
CMP - Answer-Complete Metabolic Panel
Calcium - Answer-8.5-10.9 mg/dL
Pressure on the long bones is how we get calcium. This is why ambulation is so
important for patients. It stimulates the osteoblasts to make bone and produce calcium.
If a patient has a low level of calcium it can make the patient experience jitters and
Tetany.
Anion Gap definition and norms - Answer-Measures: anions in blood (taken from serum
or plasma)
Normal gap is between 5-11 mE/L or mmols/L
Hyponatremia - Answer-Too low sodium
Too big of an Anion Gap in the blood can lead to... - Answer-Drug poisoning, renal
failure, metabolic acidosis (diabetes mellitus). If the gap is greater than normal, then
high anion gap metabolic acidosis is diagnosed.
How to determine: (cations [+] -anions [-]): - Answer-Sodium (Na+)+ Potassium (K+)-
Chloride (Cl-) + Bicarbonate (HCO3-
136 ( 136-144 mEq/L normal range) + 4 (3.7-5.2 mEq/L normal range) = 140
100 (101-111 mEq/L normal range) + 28 (20-29 mmol/L normal range) =128
In the elderly there is a decline in...? - Answer-Decrease in short term memory
Visual Acuity
Urinary elimination
Sense of smell/taste
Sensory perception (diabetes mellitus)
