Maryville NURS 611 Pathophysiology Test 1 | Questions
& Answers | Latest Update 2026 | Exam Prep | Graded
A+
1. What is a common clinical manifestation of hypernatremia?
Bradycardia
Hypotension
Nausea
Thirst
2. Describe how dehydration affects perfusion in the body.
Dehydration leads to decreased blood volume, which reduces
perfusion to organs and tissues.
Dehydration only affects muscle perfusion, not organ perfusion.
Dehydration increases blood volume, enhancing perfusion to organs.
Dehydration has no effect on perfusion.
3. Describe the physiological impact of oxygen depletion on cellular
processes.
Oxygen depletion leads to impaired cellular respiration, resulting in
decreased ATP production and potential cell death.
Oxygen depletion enhances protein synthesis and energy production.
Oxygen depletion has no significant effect on cellular processes.
Oxygen depletion only affects muscle cells, not other cell types.
4. Describe the physiological response of the body to hypernatremia.
, The body increases sodium excretion through the kidneys.
The body responds to hypernatremia by stimulating thirst and
promoting the release of antidiuretic hormone (ADH) to conserve
water.
The body decreases fluid intake and increases urine output.
The body activates the Renin-Angiotensin-Aldosterone System (RAAS)
to increase sodium retention.
5. A patient presents with symptoms of headache, nausea, and confusion. If
their serum sodium level is found to be low, what condition might they be
experiencing?
Dehydration
Hypernatremia
Kidney failure
Hyponatremia
6. Your patient is experiencing decreased perfusion as related to dehydration.
What would you observe?
changes in mentation
high blood pressure
the urge to urinate
bradycardia
7. What is the primary consequence of reduced ATP levels in cells?
Decreased energy production
Improved fluid balance
