1. 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.
2. 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.
3. In which condition would you expect to find a low white blood
cell (WBC) count?
A. Viral infection
B. Leukemia
C. Bacterial infection
D. Bone marrow suppression
Answer: D) Bone marrow suppression
Rationale: Bone marrow suppression, often caused by
chemotherapy or certain diseases, can result in low WBC counts
(leukopenia).
,4. 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.
5. Which of the following lab findings is typically seen in a patient
with acute renal failure (ARF)?
A. Increased serum creatinine
B. Decreased serum potassium
C. Decreased blood urea nitrogen (BUN)
D. Decreased urine output (oliguria)
Answer: A) Increased serum creatinine
Rationale: In acute renal failure, the kidneys' ability to excrete
waste products diminishes, leading to an increase in serum
creatinine levels.
6. 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.
7. What is a common complication of untreated hyperthyroidism?
A. Heart failure
, B. Bradycardia
C. Hypoglycemia
D. Myxedema coma
Answer: A) Heart failure
Rationale: Untreated hyperthyroidism can lead to tachycardia and
increased cardiac workload, which can eventually result in heart
failure.
8. 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.
9. 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.
10. A patient diagnosed with a brain tumor presents with sudden
weakness on one side of the body. What could this symptom
indicate?
risk of deep vein thrombosis (DVT)?
A. Frequent physical activity
B. Use of oral contraceptives

resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
