Which of the following individuals demonstrates cellular atrophy?
A middle-aged female experiencing menopause due to loss of estrogen stimulation.
A client has experienced a significant decline in mobility and stamina during a 3-week hospital
stay for the treatment of a femoral head fracture. Which of the following phenomena most
likely accounts for the client's decrease in muscle function?
Disuse atrophy of muscle cells during a prolonged period of immobility
After successful revascularization therapy for myocardial infarction, a patient's heart cells are at
increased risk of oxidative stress due to the surge of free radicals. This condition can potentially
damage cellular structures and impair function. What enzymes do cardiac cells utilize to combat
this oxidative stress and mitigate potential damage?
Peroxidases
A 55-year-old man with a long history of alcohol use presents to the emergency department
with symptoms of confusion, ataxia, and abdominal distension. Given the chronic exposure to
ethanol, which of the following pathophysiological changes are likely to be observed in this
patient? SELECT ALL THAT APPLY
- Hepatic steatosis leading to liver enlargement and dysfunction
- Increased risk of infection due to reduced circulating T cells and B cells
, - Thiamine deficiency leading to Wernicke-Korsakoff syndrome
A patient has a serum sodium level of 165 mEq/L. The healthcare professional explains that the
clinical manifestations of confusion, convulsions, cerebral hemorrhage, and coma are caused by
what mechanism?
High sodium in the blood vessels pulls water out of the brain cells into the blood vessels,
causing brain cells to shrink.
A patient with chronic heart failure is experiencing peripheral edema. The nurse practitioner
explains that this symptom is due to increased capillary hydrostatic pressure. Which of the
following best explains how increased capillary hydrostatic pressure contributes to the
development of peripheral edema?
It forces more fluid out of the capillaries into the interstitial space, exceeding the lymphatic
system's capacity for fluid return.
A regulated cellular cleanup mechanism that is triggered during times of cell stress or nutrient
deprivation, involving the lysosomal degradation of intracellular components.
Autophagy
A mechanism by which cells recycle their own organelles and protein aggregates to sustain
cellular metabolism during periods of starvation.
