Solute that moves across the cell membrane against the osmotic gradient is
- A.
Osmosis
- B.
Diffusion
- C.
Active Transport
Correct Answer
C. Active TransportExplanation
Active transport is the process by which solutes move across the cell membrane against the osmotic gradient. Unlike diffusion and osmosis, which rely on the natural movement of molecules from an area of higher concentration to an area of lower concentration, active transport requires the use of energy to transport molecules against this concentration gradient. This process is vital for maintaining proper balance and homeostasis within the cell, as it allows the cell to selectively transport specific molecules in and out of the cell, even against their natural tendency to diffuse.Rate this question:

Describe the Renin Angiotension Aldostorone Mechanism
Correct Answer
Blood pressure falls, Renin is released from the Kidneys, Renin + Blood plasma = Angiotensin I, ACE converts Angiotension I to Angiotension II (potent Vasoconstrictor), Aldostorone is released from adrenal cortex, stimulates kidney to reasorb sodium, decreases urine output and maintains fluid volume.Explanation
The Renin Angiotension Aldostorone Mechanism is a physiological process that regulates blood pressure and fluid balance in the body. When blood pressure falls, the kidneys release renin. Renin then combines with blood plasma to form Angiotensin I. Angiotensin-converting enzyme (ACE) converts Angiotensin I to Angiotensin II, which is a potent vasoconstrictor, causing blood vessels to narrow and increase blood pressure. In response to Angiotensin II, the adrenal cortex releases aldosterone, which stimulates the kidneys to reabsorb sodium, leading to decreased urine output and maintenance of fluid volume. This mechanism helps to restore blood pressure to normal levels and maintain proper fluid balance in the body.Rate this question:

Decreased blood flow to the medulla oblongata = vasoconstriction though what response...
- A.
CNS ischemic response
- B.
Spleenic Squeeze
- C.
Hypoglycemia
- D.
Trauma
Correct Answer
A. CNS ischemic responseExplanation
The decreased blood flow to the medulla oblongata causes vasoconstriction, which triggers the CNS ischemic response. This response is a protective mechanism of the central nervous system to ensure adequate blood supply to vital organs, such as the brain, during periods of reduced blood flow. It involves the release of various chemicals and neurotransmitters that help maintain cerebral perfusion and prevent further ischemic damage.Rate this question:

Define the three phases of clotting in the correct order.
Correct Answer
Vasoconstriction, platelet formation, coagulationExplanation
The three phases of clotting occur in a specific order. First, vasoconstriction takes place, which is the narrowing of blood vessels to reduce blood flow. This is followed by platelet formation, where platelets aggregate and adhere to the site of injury to form a temporary plug. Finally, coagulation occurs, which involves the activation of various clotting factors to form a fibrin mesh, stabilizing the platelet plug and forming a blood clot.Rate this question:

Gunshot wound to the abdomen results in which kind of shock?
- A.
Obstructive
- B.
Distributive
- C.
Hypovolemic
- D.
Neurologic
- E.
Cardiogenic
Correct Answer
C. HypovolemicExplanation
A gunshot wound to the abdomen can result in hypovolemic shock. Hypovolemic shock occurs when there is a significant loss of blood or fluid volume, leading to inadequate perfusion of organs and tissues. In the case of a gunshot wound to the abdomen, there is a high likelihood of severe bleeding, causing a decrease in blood volume. This decrease in blood volume leads to a decrease in cardiac output and inadequate delivery of oxygen and nutrients to the body's tissues, resulting in hypovolemic shock.Rate this question:

Anterior pituitary secretion decreases urine production.
- A.
Anti diuretic hormone (ADH)
- B.
Angiotensin II
- C.
Aldostorone
- D.
Renin
Correct Answer
A. Anti diuretic hormone (ADH)Explanation
ADH, also known as vasopressin, is a hormone released by the posterior pituitary gland that regulates water balance in the body. It acts on the kidneys to increase water reabsorption, leading to a decrease in urine production. This hormone helps to prevent excessive water loss from the body and maintain proper hydration levels. Therefore, the statement that ADH decreases urine production is correct.Rate this question:

What will a burn patient most likely die from?
Correct Answer
HYPOXIAExplanation
A burn patient is most likely to die from hypoxia, which refers to a lack of oxygen supply to the body's tissues. Severe burns can damage the respiratory system, leading to difficulty in breathing and decreased oxygen intake. Additionally, burn injuries can cause fluid loss and damage to blood vessels, resulting in decreased oxygen delivery to vital organs. This can lead to organ failure and ultimately death.Rate this question:

Burns presenting with moisture and blisters either open or closed is which type of burn....
- A.
Superficial
- B.
Full Thickness
- C.
Partial Thickness
Correct Answer
C. Partial ThicknessExplanation
The presence of moisture and blisters, whether open or closed, indicates that the burn is a partial thickness burn. In partial thickness burns, the damage extends beyond the top layer of skin (epidermis) and may also affect the underlying layer (dermis). This type of burn is characterized by pain, redness, and blister formation. Full thickness burns, on the other hand, involve damage to all layers of the skin and may appear white or charred. Superficial burns only affect the top layer of the skin and typically result in redness and pain without blistering.Rate this question:

The most serious immediate injury that occurs with electrical contact is...
- A.
Hypoxia
- B.
Cardiac Arrythmia
- C.
Hyperthermia
- D.
Shock
Correct Answer
B. Cardiac ArrythmiaExplanation
When a person comes into contact with electricity, it can disrupt the normal electrical signals in the heart, leading to cardiac arrhythmia. This means that the heart may beat too fast, too slow, or irregularly, which can be life-threatening. Cardiac arrhythmia can cause the heart to be unable to pump blood effectively, leading to organ damage or even cardiac arrest. Therefore, it is considered the most serious immediate injury that can occur with electrical contact.Rate this question:
