NU 545-UNIT 1 EXAM Q&A
Hemosiderosis - Answer-excess iron is stored as hemosiderin in cells of organs and
tissues, occurs in repeated transfusions and prolonged IV FE
Hypernatremia - Answer-Caused by water loss, acute gain in sodium--levels >147
mEq/L
Syndrome of Inappropriate Antidiuretic Hormone ( SIADH)_ - Answer-causes decreased
urine output, secondary to excess secretion of ADH.
Kaussmaul respirations- in Metabolic Acidosis - Answer-Deep, rapid breathing---
signifies respiratory compensation in acid-base imbalances
Hyperkalemia - Answer-Causes: 1. excess dietary or intravenous intake 2. decreased
renal loss: renal failure 3. shift from ICF to ECF
Hypermagnesemia - Answer-very rare and usually caused by renal failure--use of
magnesium containing antacids can potentiate excess magnesium levels
Chvostek - Answer-positive when a twitch of nose or lip is noted when tapping on the
facial nerve- just below the temple-clinical manifestation of hypocalcemia
Trousseau - Answer-contraction of hand or fingers occurs after arterial blood flow to the
arm has been occluded for 5 minutes--clinical manifestation of hypocalcemia
Edema - Answer-during inflammation edema is the increased flow and capillary
permeability resulting in leakage of plasma from the vessels,
Inflammation - Answer-protects the body from further injury, prevent infection of the
injured tissue and promote healing. The inflammatory response is a rapid activation of
biochemical and cellular processes that is relatively nonspecific, with similar responses
being initiated against a wide variety of causes of tissue damage
Neutrophils - Answer-Leukocytes that elevate when there is an early acute inflammatory
reaction--they arrive within 6-12 hours after the initial injury
endogenous pyrogens - Answer-act directly on the hypothalamus and produces fever
keloid - Answer-a raised scar that extends beyond the original boundaries of the wound
Active Immunity/ active acquired immunity - Answer-The type of immunity produces
after a natural exposure to an antigen
Hemosiderosis - Answer-excess iron is stored as hemosiderin in cells of organs and
tissues, occurs in repeated transfusions and prolonged IV FE
