What organ primarily corrects for errors in our fluid calculations?
Correct Answer
A. Kidneys
Explanation
The kidneys primarily correct for errors in our fluid calculations. The kidneys are responsible for maintaining the balance of water and electrolytes in the body by filtering waste products from the blood and producing urine. They regulate the concentration of fluids and electrolytes by reabsorbing or excreting them as needed. This helps to maintain the proper fluid balance and prevent dehydration or overhydration. The liver, pancreas, and adrenal glands have other important functions in the body, but they are not primarily involved in correcting fluid calculations.

4.
At which percentage of dehydration do we FIRST observe dry mucous membranes?
Correct Answer
B. 5%
Explanation
Dry mucous membranes are a common symptom of dehydration. As the body loses water, the mucous membranes in the mouth and nose become dry and sticky. At a dehydration level of 5%, we first observe dry mucous membranes. This means that when the body has lost 5% of its total water content, the mucous membranes start to show signs of dryness. It is important to note that dehydration can have varying symptoms and severity depending on the individual and other factors, but dry mucous membranes are typically observed at this level of dehydration.
5.
At which percentage of dehydration might we notice that the femoral pulse is has decreased?
Correct Answer
D. 10%
Explanation
At a 10% dehydration level, we might notice a decrease in the femoral pulse. Dehydration can lead to a decrease in blood volume and blood pressure, causing a weaker and slower pulse. This can be an indication that the body is not receiving enough fluid and is becoming dehydrated. It is important to stay hydrated to maintain proper blood circulation and overall health.
6.
At which percentage of dehydration might the animal begin to show signs of shock?
Correct Answer
E. 12%
Explanation
At a dehydration level of 12%, the animal may begin to show signs of shock. This is because dehydration causes a decrease in blood volume, leading to reduced oxygen and nutrient supply to the body's tissues. As a result, the animal's vital organs may not receive enough blood flow, leading to a state of shock. This can manifest as symptoms such as rapid breathing, weak pulse, pale gums, and lethargy. Therefore, a dehydration level of 12% is critical and can have severe consequences for the animal's health.
7.
The three parameters that you should always check on an examination of the mucous membranes are color, CRT, and degree of hydration.
Correct Answer

According to the lecture, vomiting is likely to cause losses in...
Correct Answer(s)
A. Acid
B. Cl-
Explanation
According to the lecture, vomiting is likely to cause losses in acid and Cl-. When a person vomits, they expel stomach acid, leading to a decrease in acid levels in the body. Additionally, the stomach contains chloride ions (Cl-), and vomiting can result in the loss of these ions. Other electrolytes like potassium (K+) and bicarbonate (HCO3) may not be affected as significantly by vomiting.
9.
According to the lecture, diarrhea is likely to cause loses in...
Correct Answer(s)
B. Cl-
C. K+
D. HCO3
Explanation
Diarrhea can cause losses in chloride (Cl-), potassium (K+), and bicarbonate (HCO3) ions. Diarrhea is characterized by frequent and loose bowel movements, which can lead to excessive loss of fluids and electrolytes from the body. Chloride, potassium, and bicarbonate are important electrolytes that help maintain the balance of fluids and pH levels in the body. When diarrhea occurs, these electrolytes are not properly absorbed by the intestines, resulting in their loss. This can disrupt the body's electrolyte balance and lead to dehydration and metabolic imbalances.
10.
Blood loss/fluid lose results in stimulation of....
Correct Answer(s)
A. Barorecptors
C. Sympathetic system
D. Renin-angiotensin system
Explanation
Blood loss or fluid loss leads to a decrease in blood volume, which causes a decrease in blood pressure. This decrease in blood pressure is detected by baroreceptors, which are specialized sensory receptors located in the walls of certain blood vessels. The activation of baroreceptors triggers a reflex response that stimulates the sympathetic nervous system. The sympathetic system then causes vasoconstriction, increased heart rate, and increased contractility of the heart, all of which work to increase blood pressure and restore blood flow. Additionally, blood loss also activates the renin-angiotensin system, which plays a role in regulating blood pressure through the release of angiotensin II, a potent vasoconstrictor.

A. 7.9 g/dl
Explanation
A total plasma protein reading of 7.9 g/dl indicates dehydration. Dehydration can cause an increase in the concentration of proteins in the blood, leading to a higher total plasma protein reading. A reading of 7.9 g/dl suggests that there is a higher concentration of proteins in the plasma, which is a sign of dehydration.
13.
Select which statement about USG is true.
Correct Answer
A. USG will increase with decreases in renal perfusion secondary to hypovolemia.
Explanation
USG stands for urine specific gravity, which is a measure of the concentration of solutes in the urine. When renal perfusion decreases due to hypovolemia (low blood volume), the kidneys try to conserve water and concentrate the urine, leading to an increase in USG. This helps to retain water in the body and prevent further fluid loss. Therefore, the statement "USG will increase with decreases in renal perfusion secondary to hypovolemia" is true.
14.
IV fluids are indicated in dogs and cats that are 7% or greater clinically dehydrated.
Correct Answer

Crystalloid fluids can be sodium-based or glucose solutions, providing electrolytes and nutrients to the body. These fluids are transient in the vascular system, meaning they do not stay in the bloodstream for an extended period of time. They are rapidly absorbed and distributed throughout the body. Crystalloid fluids do not act like albumin, which is a type of colloid fluid.
18.
Which is more likely to cause overhydration?
Correct Answer
A. Colloids
Explanation
Colloids are more likely to cause overhydration compared to crystalloids. Colloids are large molecules or particles that do not easily pass through cell membranes and tend to stay within the blood vessels, increasing the osmotic pressure. This can lead to fluid retention and overload, causing overhydration. On the other hand, crystalloids are small molecules that can easily pass through cell membranes and distribute throughout the body, resulting in less risk of overhydration.
19.
