Question 1
Physiological concepts of flight or fight response?
Correct Answer
The release of catecholamines and cortisol during the alarm stage of the generalized adaptation syndrome. SNS triggers
an acute stress response. Pupils dilate, HR and BP increases, bladder relaxes.
Rationale:
The correct answer is accurate because it describes the physiological responses triggered by the sympathetic nervous system (SNS), which is
the primary driver of the "fight or flight" response, causing pupils to dilate, heart rate and blood pressure to increase, and the bladder to relax.
This response is characterized by the release of catecholamines and cortisol, key hormones involved in the body's acute stress reaction.
Question 2
Define Homeostasis.
Correct Answer
Equilibrium of the body.
Rationale:
The correct answer, "Equilibrium of the body," is accurate because homeostasis refers to the dynamic state of balance within an organism's
internal environment, where various physiological processes work together to maintain a stable condition despite changes in external factors.
This concept focuses on the equilibrium achieved through the regulation of internal factors such as temperature, pH levels, and hormone
concentrations to preserve the body's optimal functioning.
Question 3
Function of a ribosome?
Correct Answer
Aid in protein production.
Rationale:
A ribosome plays a crucial role in translating messenger RNA (mRNA) into a sequence of amino acids, which are the building blocks of proteins,
thereby aiding in protein production. This process is essential as proteins perform a wide array of functions within cells, including catalyzing
metabolic reactions, replicating DNA, and regulating various cellular processes.

,Question 4
Hormone that raises blood sugar?
Correct Answer
Glucagon
Rationale:
Glucagon plays a crucial role in raising blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, a process
known as glycogenolysis. This action counteracts the effects of insulin, which lowers blood sugar levels, thereby maintaining a delicate balance
between the two hormones to regulate blood glucose levels.
Question 5
Main function of the endocrine system?
Correct Answer
The glands of the endocrine system secrete a wide range of hormones and chemical messengers that help regulate
growth, development, mood metabolism, and reproduction.
Rationale:
The statement is correct because it accurately describes the primary function of the endocrine system, which is to regulate various bodily
processes through the secretion of hormones and chemical messengers. This regulation enables the body to maintain homeostasis, or a stable
internal environment, which is essential for proper growth, development, and overall health.
Question 6
Function of plasma protein?
Correct Answer
Albumin, globulins, and fibrinogen. Maintains osmotic pressure, coagulation factors, transports antibodies, hormones,
lipids, vitamins, and minerals.
Rationale:
Plasma proteins, such as albumin, globulins, and fibrinogen, play crucial roles in maintaining various bodily functions, including osmotic
pressure, immune response, and coagulation. The correct answer is a comprehensive summary of these diverse functions, highlighting the
essential contributions of plasma proteins to overall health and homeostasis.
Question 7
Intracellular contain a high ____- note which electrolytes
Correct Answer
Potassium, magnesium and phosphate
Rationale:
Intracellular fluids contain a high concentration of potassium, magnesium, and phosphate because these ions are crucial for various cellular
functions such as maintaining cell membrane potential, regulating muscle contractions, and facilitating metabolic processes. Unlike sodium,
which is predominantly found in extracellular fluids, these ions play a significant role in the internal environment of cells, making them essential
components of the intracellular electrolyte balance.

, Question 8
Physiologic effect of hyponatremia?
Correct Answer
Results from low serum sodium levels (<135 mEq/L). As sodium levels decrease, water shifts into cells. This can cause
unstable gait, osteoporosis, attention deficit, cells swell.
Rationale:
Hyponatremia, or low serum sodium levels, disrupts the balance of fluids in the body, causing water to shift into cells due to the osmotic
gradient. This fluid shift leads to cell swelling, which can impair normal cellular function and result in various symptoms, including unstable
gait, attention deficits, and other complications.
Question 9
Define hypovolemia
Correct Answer
fluid deficit in the intravascular compartment
Rationale:
Hypovolemia refers to a state of reduced circulating blood volume, resulting in an insufficient amount of fluid in the intravascular compartment.
This concept is centered around the idea that the intravascular compartment is the space where blood circulates, and a fluid deficit in this
compartment indicates a decrease in the overall circulating blood volume.
Question 10
This stores electrolytes and acts like an electrolyte pool in the body
Correct Answer
the kidneys
Rationale:
The kidneys play a crucial role in regulating electrolyte balance by filtering excess electrolytes from the blood and excreting them in urine,
while also reabsorbing essential electrolytes back into the bloodstream to maintain proper ion concentrations. This electrolyte regulation allows
the kidneys to function as an electrolyte pool, storing and managing the body's supply of electrolytes, such as sodium, potassium, and calcium.
Question 11
Define "sign", "contraindication"
Correct Answer
Sign: something found during an exam, or diagnosis testing that indicates something
Contraindication: Anything (including a symptom or medical condition) that is a reason for a person to not receive a
particular treatment or procedure because it may be harmful
Rationale:
The provided answer accurately defines "sign" and "contraindication" because it clearly distinguishes between a sign, which is a detectable
indicator of a condition, and a contraindication, which is a specific reason to withhold a treatment due to potential harm. By making this
distinction, the answer correctly identifies the key concepts and relationships between signs, symptoms, and medical treatments.
