1. What is the primary cause of hypercapnia in patients with
chronic obstructive pulmonary disease (COPD)?
A. Increased carbon dioxide production
B. Airway obstruction
C. Pulmonary fibrosis
D. Decreased tidal volume
Answer: B) Airway obstruction
Rationale: In COPD, airway obstruction leads to difficulty in
exhaling CO2, resulting in the accumulation of carbon dioxide in
the bloodstream (hypercapnia).
2. 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.
3. 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.
4. A patient with cirrhosis has developed ascites. Which of the
,following is a likely cause of ascites in this patient?
A. Decreased albumin production
B. Increased clotting factors
C. Increased renin production
D. Decreased red blood cell production
Answer: A) Decreased albumin production
Rationale: In cirrhosis, the liver's ability to produce albumin is
impaired, leading to a decrease in plasma oncotic pressure, which
contributes to fluid accumulation in the abdomen (ascites).
5. A patient with diabetes mellitus presents with polyuria,
polydipsia, and weight loss. What condition might these
symptoms indicate?
A. Diabetic ketoacidosis (DKA)
B. Hyperosmolar hyperglycemic state (HHS)
C. Hypoglycemia
D. Hypertension
Answer: A) Diabetic ketoacidosis (DKA)
Rationale: DKA occurs when insulin deficiency causes increased
glucose production and fat breakdown, leading to ketosis and
elevated blood glucose levels, which cause symptoms like
polyuria, polydipsia, and weight loss.
6. A patient with acute bacterial meningitis is likely to experience
which of the following?
A. Increased thirst and urination
B. Severe headache and neck stiffness
C. Joint pain and swelling
D. Abdominal pain and bloating
Answer: B) Severe headache and neck stiffness
Rationale: Acute bacterial meningitis causes inflammation of the
meninges, leading to symptoms like severe headache, neck
stiffness, photophobia, and fever.
, 7. A patient with a history of chronic pancreatitis is at increased
risk for which of the following complications?
A. Diabetes mellitus
B. Hypoglycemia
C. Hyperkalemia
D. Asthma
Answer: A) Diabetes mellitus
Rationale: Chronic pancreatitis can damage the pancreas' ability
to secrete insulin, leading to insulin resistance and an increased
risk of diabetes mellitus.
8. What is the primary cause of atherosclerosis?
A. Decreased calcium intake
B. Chronic inflammation of the blood vessels
C. Increased HDL cholesterol
D. Vitamin D deficiency
Answer: B) Chronic inflammation of the blood vessels
Rationale: Atherosclerosis is primarily caused by the build-up of
plaque in the arteries, often triggered by chronic inflammation
and high levels of LDL cholesterol in the bloodstream.
9. What is a common sign of a urinary tract infection (UTI) in
older adults?
A. Fever and chills
B. Confusion and delirium
C. Painful urination
D. Excessive thirst
Answer: B) Confusion and delirium
Rationale: In older adults, UTIs may present with atypical
symptoms such as confusion, delirium, or agitation, rather than
the typical symptoms of fever and dysuria.
