What happens to fluid movement in the body when there are not enough plasma proteins in circulation?
Hydrostatic pressure decreases, resulting in fluid movement from the interstitial to the intravascular space.
Hydrostatic pressure increases, resulting in fluid movement from the intravascular to the interstitial space.
Osmotic pressure decreases, resulting in fluid movement from the intravascular to the interstitial space.
Osmotic pressure increases, resulting in fluid movement from the interstitial to the intravascular space.
The Correct Answer is C
Choice A reason: Decreased hydrostatic pressure reduces fluid movement out of capillaries, favoring fluid return to the intravascular space. Low plasma proteins affect oncotic, not hydrostatic, pressure, causing fluid to leak into tissues, not return to vessels, making this incorrect.
Choice B reason: Increased hydrostatic pressure, as in heart failure, pushes fluid into the interstitial space. Low plasma proteins reduce oncotic pressure, not hydrostatic, leading to edema via a different mechanism, making this choice incorrect for the described scenario.
Choice C reason: Low plasma proteins, like albumin, decrease oncotic (osmotic) pressure, reducing the force pulling fluid into capillaries. This causes fluid to move from the intravascular to the interstitial space, leading to edema, making this the correct choice.
Choice D reason: Increased osmotic pressure would pull fluid into the intravascular space, as with high plasma protein levels. Low plasma proteins decrease oncotic pressure, causing fluid to leak into tissues, not return to vessels, making this choice incorrect.

Explanation
Choice A reason: Red warm skin is not typical of pulmonary embolism. It may occur in infections or inflammation. Pulmonary embolism causes reduced lung perfusion, leading to hypoxia and systemic symptoms, not localized skin changes, making this choice incorrect.
Choice B reason: Dizziness occurs in pulmonary embolism due to reduced oxygen delivery to the brain from blocked pulmonary arteries, causing hypoxia. Decreased cardiac output from right heart strain also contributes, making this a correct manifestation of pulmonary embolism.
Choice C reason: Bradycardia is not typical; pulmonary embolism usually causes tachycardia as the heart compensates for hypoxia and increased pulmonary vascular resistance. Slow heart rate does not align with the body’s response to acute obstruction, making this incorrect.
Choice D reason: Hypoxia is a hallmark of pulmonary embolism, as blocked pulmonary arteries impair gas exchange, reducing oxygen in the blood. This leads to tissue oxygen deficiency, causing symptoms like shortness of breath, making this a correct manifestation.
Choice E reason: Chest pain in pulmonary embolism results from pleural irritation or ischemia due to blocked pulmonary arteries. The pain is often sharp and worsens with breathing, reflecting lung tissue stress, making this a correct manifestation.
Choice F reason: Tachypnea, or rapid breathing, occurs as the body attempts to compensate for hypoxia in pulmonary embolism. The respiratory system increases rate to improve oxygenation, a common response to impaired gas exchange, making this correct.

Explanation
A. Hernia causes mechanical bowel obstruction by physically trapping or compressing the intestine, preventing content passage. This aligns with the patient’s hernia, creating a structural blockage consistent with clinical findings.
B. Hypokalemia leads to functional bowel obstruction by disrupting intestinal motility through electrolyte imbalances, impairing muscle contractions without physical blockage. This matches the patient’s hypokalemia, exacerbating adynamic ileus.
C. Anesthesia from surgery causes functional bowel obstruction by slowing intestinal peristalsis, often resulting in postoperative ileus. This aligns with the patient’s recent anesthesia exposure, disrupting coordinated muscle contractions.
D. Intestinal tumor results in mechanical bowel obstruction by physically blocking or compressing the intestinal lumen, impeding content flow. The patient’s tumor aligns with this mechanism, a common cause of mechanical obstruction.
E. Pancreatitis contributes to functional bowel obstruction by causing inflammation or retroperitoneal irritation, leading to adynamic ileus without physical blockage. This matches the patient’s pancreatitis, disrupting intestinal motility.
F. Adhesions cause mechanical bowel obstruction by forming fibrous bands that kink or compress the intestine, blocking content passage. The patient’s adhesion history aligns with this, a leading cause of small bowel obstruction
