Q

When there is any direct increase of (bicarbonate) base or a decrease of metabolic acid which increases blood (bicarbonate) base by releasing it from it’s buffering function. What is this defined as?

A

Metabolic Alkalosis

Ex. Common causes include vomiting and gastric section. The respiratory compensation for metabolic alkalosis is hypoventilation. The decreased rate and depth of respiration allows carbonic acid to increase in the blood as seen by increased PaCO2. The need for oxygen may limit the degree of respiratory compensation for metabolic alkalosis.

Q

During alveolar hyperventilation, the lungs excrete too much carbonic acid (CO2 and water). The PaCO2 falls creating a deficit of carbonic acid in the blood which increases pH. This is usually short-lived, thus the kidneys do not that have time to compensate. what is this defined as?

A

Respiratory Alkalosis

Ex. When the pH of blood, CSF, and ICF increases acutely, cell membrane excitability also increases giving rise to neurological symptoms such as excitement, confusion, and paresthesias. If the pH rises high enough CNS depression may occur.

Q

These are pairs of chemicals that work together to maintain normal pH of body fluids. What is this defined as?

A

Buffers

Ex. If there are too many free H+ ions, a buffer take them up so they no longer are free. If there are too few H+ ions, a buffer can release H+ ions to prevent an acid-base imbalance. Buffers work rapidly within seconds.

A

Extracellular Fluid Volume Excess (ECV Excess)

Ex. When you eat more salty foods than usual and drink water you may notice that your ankles swell.

24
Q

When IV fluid contains additives that damage tissue and the IV infiltrates this will show clinical manifestations of coolness, paleness, and swelling of the area. When this occurs immediately assess for any additives in the infiltrated fluid to determine what type of action is necessary to prevent local tissue damage and sloughing. What is this defined as?

A

Extravasation

Ex. Vasoconstrictors, high dose potassium, and other IV additives and subcutaneous tissue need different treatments from those needed for an infiltrated additive-free IV.

Q

This is the force of the fluid pressing outward against a surface. What is this defined as?

A

Hydrostatic Pressure

Ex. Capillary hydrostatic pressure is a relatively strong outward pushing force that helps move fluid from capillaries into the interstitial fluid. Interstitial fluid hydrostatic pressure is a weaker opposing force that tends to push fluid back into the capillaries.

A

Colloid Osmotic Pressure

Interstitial fluid colloid osmotic pressure

35
Q

This is an abnormally low magnesium concentration in the blood. Caused by decreased magnesium intake and absorption, shift of plasma magnesium to it inactive bound form, and increased magnesium output. Signs and symptoms include increased neuromuscular excitability. What is is defined as?

A

Hypomagnesemia

36
Q

This arises from a gain of relatively more water than salts or loss of relatively more salt and water. The excessively dilute condition of interstitial fluid causes water to enter cells by osmosis causing the cells to swell. Signs and symptoms of cerebral dysfunction occur when brain cells well. This is a hypotonic condition. What is is defined as?

A

Hyponatremia

37
Q

This type of solution is more dilute than the blood. Ex. The plasma. What is this solution defined as?

This causes the cell to _____ at ________ mOsm/L?

A

Hypotonic

Swell at 200mOsm/L

38
Q

This occurs when an IV catheter becomes dislodged or a vein ruptures and IV fluids inadvertently enter subcutaneous tissue around the venipuncture site. What is this defined as?

A

Infiltration

41
Q

This solution has the same concentration of non-permeant particles as normal blood. What is this solution defined as?

This causes the cell to _______ at ________mOsm/L?

A

Isotonic

Have no change at 280 mOsm/L

42
Q

This occurs when there is an increase of metabolic acid or a decrease of bicarbonate (base).

A

Metabolic Acidosis

Ex. This occurs when the kidneys are unable to excrete enough metabolic acid which begin to accumulate in the blood. This also occurs when bicarbonate is removed from the body directly as diarrhea.

43
Q

This is the inflammation of a vein that results from chemical, mechanical, or bacterial causes Risk factors include acidic or hypertonic IV solution, rapid IV rate, IV drugs such as KCl, vancomycin, and penicillin, VAD inserted in the area of flexion, poorly secured catheter, poor hand hygiene, and lack of aseptic technique. What is this defined as?

A

Phlebitis

44
Q

Water moves across cell membranes by this process which water moves through a membrane that separates fluids with different particle concentrations. What is this defined as?

A

Osmosis

45
Q

This is in the inward pulling force caused by blood proteins that help move fluid from the interstitial fluid area back into the capillaries. This is also called colloid osmotic pressure. What is this defined as?

A

Oncotic Pressure

46
Q

This occurs during alveolar hypoventilation. The lungs are unable to excrete enough CO2. The PaCO2 rises creating an excess of carbonic acid in the blood, which decreases pH. kidneys compensate by increasing excretion of metabolic acids in the urine, which increases blood bi-carbonate. This compensatory process is slow often taking 24 hours to show clinical effect and 3 to 5 days to reach steady state.

A

Respiratory Acidosis

Ex. Decreased cerebral spinal fluid pH and intracellular pH of brain cells cause decreased level of consciousness.

47
Q

This is the collection and reinfusion of a patient’s own blood. This is also known as an autotransfusion. What is this defined as?

A

Autologous Transfusion

Ex. Blood for this transfusion most commonly is obtained by pre-operative donation up to six weeks before a scheduled surgery. Ex. Heart, orthopedic, plastic, or gynecological

48
Q

This is a fluid such as cerebrospinal, pleural, peritoneal, and synovial fluids These fluids are secreted by epithelial cells.

A

Transcellular Fluids

49
Q

These are catheter or infusion ports designed for repeated access to the vascular system. These are for short-term use especially for fluid restoration after surgery and short-term antibiotic administration. Devices for long-term use include central catheter is an implanted ports, which empty into a central vein.

A

Vascular Access Devices (VADs)

Remember that the term central applies to the location of the catheter tip not where the catheter is inserted into the heart.
Ex.peripherally inserted central catheter’s enter a peripheral are moving and extend to the venous system to the superior vena cava where they terminate.

50
Q

This describes a condition that tends to make the blood relatively too basic (alkaline). There are two types respiratory and metabolic. What is that defined as?

A

Alkalosis

50
Q

Blood contains albumin and other proteins known as _______. These proteins are much larger than electrolytes, glucose, and other molecules that dissolve easily. These are too large to leave capillaries in the fluid that is filtered, so they remain in the blood. These particles exert osmotic pressure.

A

Colloids

50
Q

This is present when there is insufficient isotonic fluid in the extracellular compartment. What is this defined as?

A

Extracellular Fluid Volume Deficit (ECV Deficit)

Ex. There is a lot of sodium in normal ECF with ECV deficit output of isotonic fluids exceeds intake of sodium containing fluid.
Because ECF is both vascular and interstitial; signs and symptoms arise from lack of volume in both of these compartments.

50
Q

This is an abnormally high calcium ion concentration in the blood. This results in increased calcium intake and absorption, shift of calcium from bones into the ECF, and decreased calcium output. Some signs and symptoms include decreased neuromuscular excitability and lethargy. What is this defined as?

A

Hypercalcemia

Ex. Patients with cancer often develop hypercalcemia because some cancer cells secrete chemicals into the blood that are related to parathyroid hormone. When these chemicals which the bones they cause shift of calcium from bones into the ECF.

50
Q

This is an abnormally high magnesium concentration in the blood. End-stage renal disease causes this unless the person decreases magnesium intake to match the decreased output. Signs and symptoms include decreased neuromuscular excitability lethargy and decreased deep tendon reflexes.

A

Hypermagnesemia

51
Q
