1. Which electrolyte imbalance is most commonly associated with
chronic alcoholism?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypomagnesemia
Answer: D) Hypomagnesemia
Rationale: Chronic alcoholism leads to malabsorption of nutrients,
including magnesium, resulting in hypomagnesemia.
2. Which of the following is a common cause of hypoxemia?
A. Anemia
B. Asthma
C. Hypertension
D. Diabetes
Answer: B) Asthma
Rationale: Asthma causes bronchoconstriction and inflammation
in the airways, leading to decreased oxygen exchange and
resulting in hypoxemia.
3. Which of the following would you expect in a patient with
Addison’s disease?
A. Increased blood pressure
B. Hyperkalemia
C. Weight gain
D. Increased appetite
Answer: B) Hyperkalemia
Rationale: Addison’s disease, a disorder of the adrenal glands,
leads to decreased cortisol and aldosterone production. This
results in fluid and sodium loss and potassium retention, causing
hyperkalemia.
,4. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
D. Hypertension
Answer: B) Ischemia due to a clot
Rationale: Ischemic strokes are the most common type of stroke
and occur when a clot blocks blood flow to the brain.
5. What is the main cause of type 2 diabetes?
A. Insulin resistance
B. Insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: A) Insulin resistance
Rationale: Type 2 diabetes is primarily caused by insulin
resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
6. Which of the following is the most likely cause of anaphylactic
shock?
A. Blood loss
B. Allergic reaction
C. Bacterial infection
D. Spinal cord injury
Answer: B) Allergic reaction
Rationale: Anaphylactic shock is a severe allergic reaction that
causes vasodilation and fluid leakage, leading to hypotension and
shock.
7. A patient with an ileus will most likely experience which of the
following symptoms?
, A. Increased appetite
B. Abdominal distention and nausea
C. Diarrhea
D. Hypoglycemia
Answer: B) Abdominal distention and nausea
Rationale: An ileus occurs when there is a lack of peristalsis in the
intestines, leading to abdominal distention, nausea, and inability
to pass stool or gas.
8. A nurse is caring for a patient with hyperkalemia. What is the
most concerning sign of this condition?
A. Muscle weakness
B. Shortness of breath
C. Diarrhea
D. Nausea
Answer: A) Muscle weakness
Rationale: Hyperkalemia can cause muscle weakness and
potentially life-threatening arrhythmias due to its effect on the
electrical conductivity of the heart.
9. What is the primary cause of osteoarthritis?
A. Autoimmune reaction
B. Wear and tear on the joints
C. Bacterial infection
D. Vitamin D deficiency
Answer: B) Wear and tear on the joints
Rationale: Osteoarthritis is primarily caused by the degeneration
of cartilage due to repetitive use or aging, leading to joint pain
and stiffness.
10. What is a common sign of a urinary tract infection (UTI) in
older adults?
A. Fever and chills
chronic alcoholism?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypomagnesemia
Answer: D) Hypomagnesemia
Rationale: Chronic alcoholism leads to malabsorption of nutrients,
including magnesium, resulting in hypomagnesemia.
