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. 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.
3. A patient with COPD has developed a barrel chest. What does
this physical finding indicate?
A. Emphysema
B. Pneumonia
C. Asthma
D. Acute bronchitis
Answer: A) Emphysema
,Rationale: A barrel chest is a physical characteristic seen in
emphysema, a type of COPD. It occurs due to the hyperinflation
of the lungs, which causes the chest to assume a rounded,
expanded shape.
4. A nurse is caring for a patient with rheumatoid arthritis. Which
of the following is a common manifestation of this condition?
A. Symmetrical joint pain and swelling
B. Morning dizziness and fatigue
C. Unilateral leg swelling
D. Chest pain
Answer: A) Symmetrical joint pain and swelling
Rationale: Rheumatoid arthritis typically causes symmetrical joint
pain, stiffness, and swelling, particularly in the hands and feet.
5. Which of the following is a primary complication of untreated
hypertension?
A. Diabetes
B. Stroke
C. Asthma
D. Hyperthyroidism
Answer: B) Stroke
Rationale: Untreated hypertension can cause damage to blood
vessels, increasing the risk of a stroke due to the development of
atherosclerosis or rupture of a weakened vessel.
6. 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.
7. Which of the following is a common sign of hypovolemic
shock?
A. Bradycardia
B. Tachycardia
C. Warm skin
D. Hypertension
Answer: B) Tachycardia
Rationale: In hypovolemic shock, blood volume decreases, and the
body compensates by increasing the heart rate (tachycardia) to
maintain blood flow to vital organs.
8. 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.
9. 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
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.

hypertension?
A. Diabetes
B. Stroke
C. Asthma
D. Hyperthyroidism
Answer: B) Stroke
