1. A client with chronic kidney disease is likely to
exhibit which serum laboratory abnormality?
A. Hypokalemia
B. Hypercalcemia
C. Hyperphosphatemia
D. Metabolic alkalosis
Rationale: The failing kidneys cannot excrete
phosphorus, leading to hyperphosphatemia.
Hypocalcemia, hyperkalemia, and metabolic
acidosis are also expected.
,2. The primary pathophysiological mechanism in
emphysema is:
A. Chronic inflammation and mucus
hypersecretion
B. Destruction of alveolar walls and loss of
elastic recoil
C. Reversible bronchospasm and airway edema
D. Permanent bronchial dilation from recurrent
infection
Rationale: Emphysema involves the
destruction of the alveoli and loss of elastic
recoil, leading to air trapping. Chronic
inflammation and mucus hypersecretion are
characteristic of chronic bronchitis.
3. A patient who sustained a spinal cord injury at
C5 is at the greatest risk for which
complication?
A. Spastic bladder
B. Neurogenic shock
C. Autonomic dysreflexia
D. Malignant hyperthermia
Rationale: Injuries above T6 can lead to
, neurogenic shock from the loss of sympathetic
nervous system innervation, causing
bradycardia and hypotension.
4. Which clinical finding best differentiates
diabetic ketoacidosis (DKA) from hyperosmolar
hyperglycemic state (HHS)?
A. Severe hyperglycemia
B. Profound dehydration
C. Presence of ketones in the blood and urine
D. Altered mental status
Rationale: DKA is defined by ketosis and
acidosis due to a lack of insulin. HHS has severe
hyperglycemia and dehydration but minimal to
no ketone production.
5. A client with left-sided heart failure is most
likely to present with:
A. Pulmonary edema and dyspnea
B. Jugular vein distention and ascites
C. Peripheral edema and hepatomegaly
D. Nocturia and weight gain
Rationale: Left-sided heart failure causes blood
, to back up into the pulmonary circulation,
leading to fluid accumulation in the lungs
(pulmonary edema) and shortness of breath.
6. The primary cause of a pulmonary embolism is:
A. Amniotic fluid entering the maternal
circulation
B. Fat globules from a fractured long bone
C. A thrombus that originated in a deep vein of
the legs
D. An air bubble introduced via a central venous
catheter
Rationale: Most pulmonary emboli are the
result of a deep vein thrombosis (DVT) in the
lower extremities that dislodges and travels to
the pulmonary arteries.
7. The hallmark pathophysiological feature of
rheumatoid arthritis is:
A. Uric acid crystal deposition in the joints
B. Wear-and-tear degeneration of cartilage
C. Autoimmune inflammation of the synovial
membrane
