QUESTION 1
A nurse is assessing a patient with chronic obstructive pulmonary disease (COPD).
What is the primary pathophysiological change associated with COPD?
A) Increased lung compliance
B) Airway obstruction due to inflammation and mucus production
C) Decreased alveolar surface area
D) Hyperventilation
ANSWER: B) Airway obstruction due to inflammation and mucus production
Rationale: COPD is characterized by chronic inflammation of the airways, leading to
obstruction caused by mucus production and changes in lung structure.
QUESTION 2
A patient presents with a sudden onset of chest pain and shortness of breath. Which
condition should the nurse suspect based on these symptoms?
A) Myocardial infarction
B) Pulmonary embolism
C) Asthma attack
D) Pneumonia
ANSWER: B) Pulmonary embolism
Rationale: Sudden chest pain and shortness of breath are classic symptoms of a
pulmonary embolism, often caused by a thrombus lodging in the pulmonary arteries.
QUESTION 3
A patient diagnosed with type 1 diabetes mellitus has elevated blood glucose levels.
What is the underlying pathophysiological mechanism?
A) Insulin resistance
B) Destruction of pancreatic beta cells
,C) Increased glucagon secretion
D) Excessive hepatic glucose production
ANSWER: B) Destruction of pancreatic beta cells
Rationale: Type 1 diabetes is primarily caused by the autoimmune destruction of
pancreatic beta cells, leading to insufficient insulin production.
QUESTION 4
A nurse is caring for a patient with heart failure. Which compensatory mechanism is the
body likely to employ in response to decreased cardiac output?
A) Decreased heart rate
B) Activation of the renin-angiotensin-aldosterone system (RAAS)
C) Increased peripheral resistance
D) Decreased fluid retention
ANSWER: B) Activation of the renin-angiotensin-aldosterone system (RAAS)
Rationale: In heart failure, the body activates the RAAS to help retain fluid and sodium,
increasing blood volume and improving cardiac output.
QUESTION 5
A patient with liver cirrhosis is experiencing ascites. What is the primary
pathophysiological change responsible for this condition?
A) Increased protein synthesis
B) Increased portal hypertension
C) Decreased renal blood flow
D) Increased albumin levels
ANSWER: B) Increased portal hypertension
Rationale: Ascites in liver cirrhosis is mainly due to increased portal hypertension,
leading to fluid leakage into the abdominal cavity.
QUESTION 6
A nurse is reviewing lab results for a patient with suspected renal failure. Which
laboratory finding would be most indicative of this condition?
A) Increased hemoglobin
B) Elevated creatinine levels
C) Decreased potassium
D) Increased calcium
,ANSWER: B) Elevated creatinine levels
Rationale: Elevated creatinine levels are a key indicator of impaired renal function,
reflecting the kidneys' inability to excrete waste.
QUESTION 7
A patient is diagnosed with anemia. What is the primary pathophysiological mechanism
that can lead to iron-deficiency anemia?
A) Decreased red blood cell lifespan
B) Insufficient iron intake or absorption
C) Increased erythropoiesis
D) Bone marrow failure
ANSWER: B) Insufficient iron intake or absorption
Rationale: Iron-deficiency anemia is primarily caused by inadequate iron intake or
absorption, leading to decreased hemoglobin production.
QUESTION 8
A nurse is assessing a patient with pneumonia. What is the primary pathophysiological
process occurring in the lungs?
A) Inflammation of the alveoli
B) Bronchoconstriction
C) Increased lung compliance
D) Decreased respiratory rate
ANSWER: A) Inflammation of the alveoli
Rationale: Pneumonia involves inflammation and consolidation of the alveoli, leading
to impaired gas exchange.
QUESTION 9
A patient with diabetes mellitus presents with a blood glucose level of 600 mg/dL and
fruity-smelling breath. What condition should the nurse suspect?
A) Hypoglycemia
B) Diabetic ketoacidosis (DKA)
C) Hyperglycemic hyperosmolar state (HHS)
D) Lactic acidosis
ANSWER: B) Diabetic ketoacidosis (DKA)
, Rationale: DKA is characterized by hyperglycemia, ketone production, and fruity breath
due to the presence of acetone.
QUESTION 10
A nurse is caring for a patient with rheumatoid arthritis. What is the primary
pathophysiological change associated with this condition?
A) Bone resorption
B) Autoimmune destruction of synovial tissue
C) Osteoblast activity
D) Increased joint mobility
ANSWER: B) Autoimmune destruction of synovial tissue
Rationale: Rheumatoid arthritis involves an autoimmune response that leads to
inflammation and destruction of the synovial tissue in joints.
QUESTION 11
A nurse is assessing a patient with chronic kidney disease (CKD). Which electrolyte
imbalance is most likely to occur?
A) Hyperkalemia
B) Hypocalcemia
C) Hyponatremia
D) Hypermagnesemia
ANSWER: A) Hyperkalemia
Rationale: CKD often leads to an accumulation of potassium in the blood due to
decreased renal excretion, resulting in hyperkalemia.
QUESTION 12
A patient with heart failure is prescribed a diuretic. What is the primary therapeutic
effect of this medication?
A) Increase blood pressure
B) Reduce fluid overload
C) Decrease heart rate
D) Increase cardiac output
ANSWER: B) Reduce fluid overload
Rationale: Diuretics are used in heart failure to promote the excretion of excess fluid,
alleviating symptoms of congestion and edema.
