1. 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.
2. A patient has been diagnosed with tuberculosis (TB). Which of
the following is the most common symptom?
A. Night sweats
B. Joint pain
C. Hematuria
D. Abdominal pain
Answer: A) Night sweats
Rationale: Night sweats are a classic symptom of tuberculosis,
along with cough and weight loss.
3. Which of the following factors is most likely to increase the
risk of deep vein thrombosis (DVT)?
A. Frequent physical activity
B. Use of oral contraceptives
C. Low body weight
D. Dehydration
Answer: B) Use of oral contraceptives
Rationale: Oral contraceptives can increase clotting factor
,production, which elevates the risk of DVT.
4. 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.
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. What is a key characteristic of Crohn's disease?
A. Continuous inflammation of the colon
B. Painless, non-bloody diarrhea
C. Skip lesions along the gastrointestinal tract
D. Gallstone formation
Answer: C) Skip lesions along the gastrointestinal tract
Rationale: Crohn’s disease is characterized by inflammation that
can occur in patches (skip lesions) throughout the gastrointestinal
tract, leading to symptoms like diarrhea, abdominal pain, and
weight loss.
, 7. What is the most common cause of peptic ulcers?
A. Stress
B. Use of nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Helicobacter pylori infection
D. Excessive alcohol consumption
Answer: C) Helicobacter pylori infection
Rationale: H. pylori infection is the leading cause of peptic ulcers
due to its ability to disrupt the mucosal lining of the stomach.
8. Which of the following lab results is most likely in a patient
with dehydration?
A. Low hematocrit
B. Low sodium levels
C. Elevated blood urea nitrogen (BUN)
D. Low creatinine
Answer: C) Elevated blood urea nitrogen (BUN)
Rationale: Dehydration leads to decreased renal perfusion and an
increase in BUN due to reduced fluid volume.
9. A patient with chronic kidney disease (CKD) is most at risk for
which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypocalcemia
Answer: A) Hyperkalemia
Rationale: In CKD, the kidneys are unable to excrete potassium
effectively, leading to the accumulation of potassium in the blood,
resulting in hyperkalemia.
10. A patient with COPD has developed a barrel chest. What does
this physical finding indicate?
A. Emphysema
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.

resulting in hypoxemia.
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.
