NURS 6003 M3 questions with correct answers
Benign tumor Correct Answer-slow growth, usually get larger but do not
spread. Cells are well differentiated. Examples: adenoma, angioma,
papilloma
Malignant tumor Correct Answer-quickly growing and infiltrate into
organs, spread through the blood stream or lymphatic channels
paraneoplastic syndrome Correct Answer-when cancers produce
chemicals that act in other parts of the body and create other issues.
Examples: ectopic cushings, SIADH
why does muscle cramping, seizures, and tetany occur in hypocalcemia?
Correct Answer-Calcium is important in the cellular chemical gradient
and when it is too low, the threshold for the action potentials are also
lowered
mechanism of action loop diuretics Correct Answer-inhibit sodium
potassium cotransporter meaning that there is increased excretion of
those two components
Decrease blood calcium
mechanism of action thiazide diuretics Correct Answer-inhibit sodium
chloride cotransporter meaning that there is increased excretion of
sodium chloride, also increases excretion of potassium. These diuretics
do a better job at lowering blood pressure
Increase blood calcium
, How do the kidneys regulate blood pressure? Correct Answer-By
secreting the enzyme renin; adjusting renal resistance, increasing sodium
and water reabsorption
Role of ADH Correct Answer-inhibits the excretion of water thus
helping to maintain blood volume/pressure. It is also triggered by RAAS
and works in conjunction with aldosterone.
Causes of edema Correct Answer-Fluid accumulates in the interstitial
space due to increased pressure and or protein concentration gradient
across the blood vessel walls. Some specific causes include increased
capillary filtration pressure, decreased capillary osmotic pressure,
increased capillary permeability, and obstructed lymph flow.
conditions cause metabolic acidosis with high anion gap Correct
Answer-MUDPILES
Methanol, Uremia, DKA, Propylene glycol, Iron tab or INH, Lactic
acidosis, Ethylene glycol, Salicylate/sepsis, starvation
conditions cause metabolic acidosis with normal anion gap Correct
Answer-diarrhea, renal tubular acidosis
Causes of Metabolic acidosis Correct Answer-Acidemia caused by
overproduction of fixed acid or loss of base
