A client is brought to the emergency True
department with a burn injury. The
nurse knows that the first is systemic
instability. True/ False
ON QUIZ/EXAM
Which is the correct interpretation of D. Metabolic Alkalosis
this arterial blood gas (ABG)?
pH = 7.5 Rationale: The pH is above the normal range
PaCO2 = 37 indicating alkalosis. The CO2 is within normal range
HCO3 = 30 indicating no respiratory involvement. The HCO3 is
above normal range indicating alkalosis. When the
A.Respiratory Acidosis body absorbs too much bicarbonate, this creates a
B.Respiratory Alkalosis metabolic imbalance.
C.Metabolic Acidosis
Metabolic Alkalosis
Is the following statement true or False
false?
Rationale: Although diffusion occurs when fluid
Diffusion is the process by which moves from an area of higher to lower concentration,
solutes move from an area of higher this process does not require an expenditure of
concentration to one of lower energy.
concentration and requires energy.
, Is the following statement true or True
false?
Rationale: Tonicity is the tension that osmotic
An isotonic solution, such as 0.9% pressure of a solution with impermeable solutes
NaCl (Normal Saline), is the only exerts on cell size because of water movement
intravenous solution that may be across the cell membrane. Normal saline has nearly
administered with blood products. the same tonicity as plasma.
IF a blood culture is prescribed, that True!
specimen is ALWAYS drawn first.
True/False Rationale: Order of Draw! Do blood cultures first
then go by color cap. If not followed, some of the
additives can be added from one tube to another
leading to contamination/ misdiagnosis
Do you do aerobic or anaerobic first? Aerobic first!
•When blood cultures are ordered (this is to minimize the potential for contamination
with other lab tests, the blood culture during the draw process, since the whole purpose of
specimen is ALWAYS drawn first culturing the blood is to discover if the blood stream
is infected with an organism so one takes precaution
to avoid contamination of blood culture specimens)
When blood cultures are ordered, blood is put into
BOTH an anaerobic AND an aerobic bottle • An
order for a single blood culture means one venous
"stick" with blood put into BOTH an anaerobic AND
an aerobic bottle • An order for "paired blood
cultures" means collection of blood from TWO
DIFFERENT sites (serves as a control for false
negatives and false positives) • The bottles are
different colors (anaerobic and aerobic) & fill
volumes required are printed on the bottles
