NSG 5003 WEEK 10 QUIZ | NSG 5003 Final week 10 Questions & Answers-Understanding the various steps of proteolytic cascades, such as caspase-mediated
... [Show More] apoptosis and complement cascades, may be useful in designing drug therapy for which human diseases? - Autoimmune and malignant disorders
Why is it possible for potassium to diffuse easily into and out of cells? - The resting plasma membrane is more permeable to potassium
The loss of the adenosine triphosphate (ATP) during ischemia causes cells to - swell because of the influx of sodium chloride
Free radicals play a major role in the initiation and progression of which diseases - Cardiovascular diseases such as hypertension and ischemic heart disease
Free Radicals cause cell damage by: - Giving up an electron, which causes injury to the chemical bonds of the cell membrane
What is a consequence of plasma membrane damage to the mitochondria? - Influx of calcium ions halts ATP production.
What is a consequence of leakage of lysosomal enzymes during chemical injury? - Enzymatic digestion of the nucleus and nucleolus occurs, halting DNA synthesis.
Which statement is a description of the characteristics of apoptosis? - Programmed cell death of scattered, single cells
During cell injury caused by hypoxia, an increase in the osmotic pressure occurs within the cell because - Sodium chloride enters the cell
What physiologic change occurs during heat exhaustion? - Hemoconcentration occurs because of the loss of salt and water.
In hypoxic injury, sodium enters the cell and causes swelling because - ATP is insufficient to maintain the pump that keeps sodium out of the cell.
What is the cause of free calcium in the cytosol that damages cell membranes by uncontrolled enzyme activation? - Depletion of ATP normally pumps calcium from the cell.
What is the single most common cause of cellular injury? - Hypoxic injury
During cell injury caused by hypoxia, sodium and water move into the cell because - The pump that transports sodium out of the cell cannot function because of a decrease in ATP levels.
Current research has determined that chemical-induced cellular injury: - Is often the result of the damage caused by reactive free radicals.
A major determinant of the resting membrane potential necessary for the transmission of nerve impulses is the ratio between - Intracellular and extracellular K+
During acidosis, the body compensates for the increase in serum hydrogen ions by shifting hydrogen ions into the cell in exchange for which electrolyte? - Potassium
Causes of hyperkalemia include: - Renal failure and Addison disease
In hyperkalemia, what change occurs to the cells' resting membrane potential? - Hypopolarization
The calcium and phosphate balance is influenced by which three substances? - Parathyroid hormone, calcitonin, and vitamin D
It is true that Kussmaul respirations indicate: - A compensatory measure is needed to correct metabolic acidosis.
Chvostek and Trousseau signs indicate which electrolyte imbalance? - Hypocalcemia
An excessive use of magnesium-containing antacids and aluminum-containing antacids can result in: - Hypophosphatemia [Show Less]
