HCR 240 Final Exam Newest With
Questions And Answers
2026/2027|100% Correct
Pathophysiology of Acute cystitis - ANSWER>Usually bacteria, often E. coli, ascend through urethra into bladder.
Clinical manifestations of Acute cystitis - ANSWER>Dysuria, frequency, urgency, suprapubic pain, cloudy urine,
possible hematuria.
High-yield fact for Acute cystitis - ANSWER>Cystitis is lower UTI.
Pyelonephritis - ANSWER>kidney infection
Cystitis - ANSWER>bladder infection
Clinical manifestations of Pyelonephritis - ANSWER>Fever, chills, flank pain, nausea/vomiting, costovertebral angle
tenderness, WBCs in urine
,Clinical manifestations of Cystitis - ANSWER>Burning, urgency, frequency, suprapubic pain
AKI - ANSWER>sudden decrease in kidney function
Prerenal AKI - ANSWER>Problem before kidney
Examples of Prerenal AKI causes - ANSWER>Dehydration, shock, heart failure, blood loss
Intrarenal AKI - ANSWER>Problem inside kidney
Cell injury - ANSWER>happens when a cell is exposed to stress that it cannot adapt to
Reversible cell injury - ANSWER>injury that is mild or short-term
Irreversible cell injury - ANSWER>injury that is severe or prolonged
Outcome of severe or prolonged cell injury - ANSWER>it becomes irreversible and leads to cell death
, Outcome of mild or short-term cell injury - ANSWER>it can be reversible
What is the fundamental definition of hypoxic injury? - ANSWER>Hypoxic injury occurs when a cell does not receive
sufficient oxygen to maintain its normal functions.
Why is oxygen critical for cellular survival? - ANSWER>Oxygen is required to produce ATP, which serves as the
primary energy source for the cell's metabolic processes, including the operation of ion pumps.
What is the sequence of events leading from low oxygen to cell death? - ANSWER>Low oxygen leads to low ATP,
which causes the sodium-potassium pump to fail. Sodium accumulates inside the cell, drawing water in via
osmosis, resulting in cell swelling, dysfunction, and eventually cell death if the condition persists.
What are common clinical causes of hypoxic injury? - ANSWER>Common causes include heart attack, stroke,
anemia, shock, respiratory failure, and carbon monoxide poisoning.
Which organs are most susceptible to hypoxic injury and why? - ANSWER>The brain, heart, and kidneys are most
susceptible because they have high metabolic demands and require a constant, significant supply of oxygen.
