Question 1
Which electrolyte imbalance is most critical to monitor for potential life-threatening cardiac
dysrhythmias and complications?
A) Hypernatremia
B) Hypokalemia
C) Hypophosphatemia
D) Hypermagnesemia
E) Hypochloremia
Correct Answer: B) Low potassium (Hypokalemia)
Rationale: Potassium is essential for the electrical conduction of the heart. Low levels
(hypokalemia) can lead to severe cardiac complications and dysrhythmias, necessitating
close heart monitoring.
Question 2
During the "fight or flight" response, which catecholamines are released to increase heart rate
and blood pressure?
A) Insulin and Glucagon
B) Estrogen and Progesterone
C) Epinephrine and Norepinephrine
D) Serotonin and Dopamine
E) Aldosterone and ADH
Correct Answer: C) Epinephrine, norepinephrine, cortisol
Rationale: The flight or fight response triggers the sympathetic nervous system to release
catecholamines (epinephrine and norepinephrine) and cortisol to increase cardiac output
and blood pressure.
Question 3
Which plasma protein is primarily responsible for maintaining oncotic pressure, and when
decreased, leads to fluid escaping into the interstitial space (edema)?
A) Hemoglobin
B) Fibrinogen
C) Albumin
D) Globulin
E) Myoglobin
Correct Answer: C) Function of Albumin - decrease albumin - ascites
Rationale: Albumin keeps water within the intravascular space. When albumin levels drop,
water escapes into the interstitial space or peritoneal cavity (ascites), causing swelling.
Question 4
The primary function of the hormone aldosterone is to promote the:
, 2
A) Excretion of sodium and water
B) Retention of sodium and water
C) Excretion of calcium
D) Retention of potassium
E) Breakdown of glycogen
Correct Answer: B) Sodium and water retention
Rationale: Aldosterone is a mineralocorticoid that acts on the kidneys to conserve sodium
and water, which increases blood volume and pressure.
Question 5
Which of the following is considered a "subjective" finding provided by the patient?
A) A blood pressure reading of 140/90
B) A visible skin rash on the arm
C) A patient reporting a "pounding headache"
D) A heart rate of 110 beats per minute
E) An elevated white blood cell count
Correct Answer: C) A patient reporting a "pounding headache"
Rationale: A symptom is subjective (what the patient feels), while a sign is objective (what
the provider observes or measures).
Question 6
Which of the following conditions are classic examples of a Type 3 hypersensitivity (immune
complex) reaction?
A) Allergic rhinitis and Asthma
B) Transfusion reactions
C) Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE)
D) Poison ivy and Tuberculosis skin test
E) Graft rejection
Correct Answer: C) Type 3 hypersensitivity reaction examples
Rationale: Type 3 reactions involve the deposition of antigen-antibody complexes in tissues,
leading to inflammation, as seen in RA and SLE.
Question 7
A nurse is conducting a blood pressure screening at a local health fair. This is an example of
which level of prevention?
A) Primary
B) Secondary
C) Tertiary
D) Quaternary
E) Palliative
Correct Answer: B) Secondary
, 3
Rationale: Secondary prevention focuses on early detection and screening of diseases to
manage them before they worsen.
Question 8
Why is severe hyponatremia considered a medical emergency for the central nervous system?
A) It causes the blood to clot too quickly
B) It leads to irreversible bone loss
C) It can cause fatal brain swelling and nervous system changes
D) It results in high ammonia levels in the liver
E) It prevents the absorption of Vitamin B12
Correct Answer: C) Fatal to brain- Nervous system changes
Rationale: Low sodium levels (hyponatremia) cause water to shift into brain cells, leading to
cerebral edema, which is potentially fatal.
Question 9
Metastatic cancer cells are characterized by their ability to:
A) Undergo apoptosis upon signal
B) Remain confined to the original tissue
C) Ignore signals for apoptosis and invade nearby organs
D) Produce excessive red blood cells
E) Increase the production of insulin
Correct Answer: C) They will not listen to the signals of apoptosis cell death. They
communicate and invade nearby organs
Rationale: Cancer cells lack "contact inhibition" and ignore cell death signals, allowing
them to proliferate and spread (metastasize) to distant organs.
Question 10
Which cellular organelle is known as the "Powerhouse" because it generates ATP?
A) Ribosome
B) Golgi apparatus
C) Mitochondria
D) Nucleus
E) Lysosome
Correct Answer: C) Function of the mitochondria
Rationale: The mitochondria are responsible for cellular respiration and the production of
energy in the form of ATP.
Question 11
What is the primary function of ribosomes within the cell?
A) DNA replication
B) Production of protein synthesis
, 4
C) Digestion of waste products
D) Storage of calcium
E) Neutralization of toxins
Correct Answer: B) Helps with the production of proteins synthesis.
Rationale: Ribosomes are the sites where genetic code is translated into proteins.
Question 12
Which of the following is the primary function of bone marrow?
A) Filtration of lymph fluid
B) Secretion of insulin
C) Hematopoiesis (production of RBC, WBC, and platelets)
D) Storage of glycogen
E) Production of growth hormone
Correct Answer: C) Helps in the production of RBC, WBC, and platelets. Hematopoiesis
Rationale: Bone marrow is the primary site for the development of all blood cells.
Question 13
Which of the following are the four classic assessment findings of localized inflammation?
A) Fever, chills, malaise, headache
B) Swelling, pain, redness, warmth
C) Pallor, numbness, coldness, tingling
D) Rigidity, jaundice, cyanosis, itching
E) Atrophy, bleeding, bruising, scabbing
Correct Answer: B) Swelling, pain, redness, warmth
Rationale: Localized inflammation is characterized by rubor (redness), calor (heat), tumor
(swelling), and dolor (pain).
Question 14
Leukemia is best described as a condition involving:
A) An absolute deficiency of white blood cells
B) Uncontrolled modification of immature white blood cells leading to bone marrow suppression
C) Excessive production of mature red blood cells
D) A deficiency in clotting factors
E) The presence of Reed-Sternberg cells
Correct Answer: B) Leukemia
Rationale: Leukemia involves the overproduction of dysfunctional, immature WBCs that
crowd out healthy RBCs and platelets in the bone marrow.
Question 15
A patient receives a vaccination and develops immunity. This is an example of:
A) Passive immunity
