Homeostasis

Answer 22

The tendency of a biological system to maintain relatively constant conditions in the internal environment whole continuously interacting with and adjusting to changes originating within or outside the system.

Question 23

Infiltration

Answer 23

Seepage of IV fluid out of the vein and into the surround interstitial spaces.

Question 24

Magnesium (Mg)

Answer 24

Concentrated in the bone, cartilage, and within the cell itself; required for the use of adenosine triphosphate as a source of energy. It is necessary for the action of numerous enzyme systems such as those involved in carbohydrate metabolism, protein synthesis, nucleic acid synthesis, and contraction of muscular tissue. It also regulates neuromuscular activity and the clotting mechanism.

Question 25

Magnesium (Mg) - Normal Adult Level (Lab Value)

Answer 25

1.5-2.5 mEq/L

Question 26

Malnutrition

Answer 26

Deficiency of the nutrients required for development and maintenance of the human body.

Question 27

Metabolic acidosis

Answer 27

A total concentration of buffer base that is lower than normal, with a relative increase in the hydrogen ion concentration. This results from loss of buffer bases or retention of too many acids without sufficient bases, and occurs in conditions such as kidney failure and diabetic ketoacidosis, from the production of lactic acid, and from the ingestion of toxins, such as acetylsalicylic acid (aspirin).

Question 28

Metabolic alkalosis

Answer 28

A deficit or loss of hydrogen ions or acids or an excess of base (bicarbonate) that results from the accumulation of base or from a loss of acid without a comparable loss of base in the body fluids. This occurs in conditions resulting in hypovolemia, the loss of gastric fluid, excessive bicarbonate intake, the massive transfusion of whole blood, and hyperaldosteronism.

Question 29

Metabolism

Answer 29

Ongoing chemical process within the body that converts digested nutrients into energy for the functioning of body cells.

Question 30

Nutrients

Answer 30

Carbohydrates, fats or lipids, proteins, vitamins, minerals, electrolytes, and water that must be supplied in adequate amounts to provide energy, growth, development, and maintenance of the human body.

Question 31

Packed red blood cells

Answer 31

A blood product used to replace erythrocytes lost as a result of trauma or surgical interventions or in clients with bone marrow suppression.

Question 32

Parenteral nutrition (PN)

Answer 32

Administration of nutritionally complete formula through a central or peripheral IV catheter. In the clinical setting, the term PN may be used interchangeably with TPN or hyperalimentation.

Question 33

Phlebitis

Answer 33

An inflammation of the vein that can occur from mechanical or chemical (medication) trauma or from a local infection.

Question 34

Phosphorus (Phos)

Answer 34

Needed for generation of bony tissue. It functions in the metabolism of glucose and lipids, in the maintenance of acid-base balance, and in the storage and transfer of energy from one sit in the body to another. Phosphorus levels are evaluated in relation to calcium levels because of their inverse relationship; when calcium levels are decreased, phosphorus levels are increased, and when phosphorus levels are decreased, calcium levels are increased.

Question 35

Phosphorus (Phos) - Normal Adult Level (Lab Value)

Answer 35

2.5-4.5 mg/dL

Question 36

Plasma

Answer 36

The watery, straw-colored, fluid part of lymph and the blood in which the formed elements (blood cells) are suspended. Plasma is made up of water, electrolytes, protein, glucose, fats, bilirubin, and gases and is essential for carrying the cellular elements of the blood through the circulation.

Question 37

Platelet transfusion

Answer 37

A blood product administered to clients with low platelet counts and to thrombocytopenic clients who are bleeding actively or are scheduled for an invasive procedure.

Question 38

Potassium (K)

Answer 38

A principal electrolyte of intracellular fluid and the primary buffer within the cell itself. It is needed for nerve conduction, muscle function, acid-base balance, and osmotic pressure. Along with calcium and magnesium, potassium controls the rate and force of contraction of the heart and thus cardiac output.

Question 39

Potassium (K) - Normal Adult Level (Lab Value)

Answer 39

3.5-5.0 mEq/L

Question 40

Respiratory acidosis

Answer 40

A total concentration of buffer base that is lower than normal, with a relative increase in hydrogen ion concentration; thus a greater number of hydrogen ions is circulating in the blood than the buffer system can absorb. This is caused by primary defects in the function of the lungs or by changes in normal respiratory patterns as a result of secondary problems. Any condition that causes an obstruction of the airway or depresses respiratory status can cause respiratory acidosis.

Question 41

Respiratory alkalosis

Answer 41

A deficit of carbonic acid or a decrease in hydrogen ion concentration that results from the accumulation of base or from a loss of acid without a comparable loss of base in the body fluids. This occurs in conditions that cause overstimulation of the respiratory system.

Question 42

Rh factor

Answer 42

Rh stands for rhesus factor. A person having the factor is Rh positive; a person lacking the factor is Rh negative. The presence or absence of Rh antigens on the surface of RBCs determines the classification as Rh positive or Rh negative.

Question 43

Septicemia

Answer 43

The presence of infective agents or their toxins in the bloodstream. Septicemia is a serious infection and must be treated promptly; otherwise, the infection leads to circulatory collapse, profound shock, and death.

Question 44

Serum

Answer 44

The clear and thin fluid part of blood that remains after coagulation. Serum contains no blood cells, platelets, or fibrinogen.

Question 45

Sodium (Na)

Answer 45

An abundant electrolyte that maintains osmotic pressure and acid-base balance and transmits nerve impulses.

Question 46

Sodium (Na) - Normal Adult Level (Lab Value)

Answer 46

135-145 mEq/L

Question 47

Transfusion reaction

Answer 47

A hemolytic reaction caused by blood type or Rh incompatibility. An allergic transfusion reaction most often occurs in clients with a history of an allergy. A febrile transfusion reaction most commonly occurs in clients with antibodies directed against the transfused WBCs. A bacterial transfusion reaction occurs after transfusion of contaminated blood products.

Question 48

Venipuncture

Answer 48

Puncture into a vein to obtain a blood specimen for testing; the antecubital veins are the veins of choice because of ease of access.
