1. 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.
2. A patient with hypothyroidism is most likely to have which of
the following symptoms?
A. Weight loss
B. Increased heart rate
C. Cold intolerance
D. Heat intolerance
Answer: C) Cold intolerance
Rationale: Hypothyroidism leads to reduced metabolism, causing
symptoms such as cold intolerance, weight gain, and fatigue.
3. 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.
,4. What is the primary cause of hypercapnia in patients with
chronic obstructive pulmonary disease (COPD)?
A. Increased carbon dioxide production
B. Airway obstruction
C. Pulmonary fibrosis
D. Decreased tidal volume
Answer: B) Airway obstruction
Rationale: In COPD, airway obstruction leads to difficulty in
exhaling CO2, resulting in the accumulation of carbon dioxide in
the bloodstream (hypercapnia).
5. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
D. Hypertension
Answer: B) Ischemia due to a clot
Rationale: Ischemic strokes are the most common type of stroke
and occur when a clot blocks blood flow to the brain.
6. A patient is being treated for acute pancreatitis. What is a
common complication of this condition?
A. Renal failure
B. Chronic diarrhea
C. Hyperglycemia
D. Gallstones
Answer: A) Renal failure
Rationale: Acute pancreatitis can lead to systemic complications,
including renal failure, due to inflammation and the release of
digestive enzymes into the bloodstream.
7. 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).
8. A patient with an ileus will most likely experience which of the
following symptoms?
A. Increased appetite
B. Abdominal distention and nausea
C. Diarrhea
D. Hypoglycemia
Answer: B) Abdominal distention and nausea
Rationale: An ileus occurs when there is a lack of peristalsis in the
intestines, leading to abdominal distention, nausea, and inability
to pass stool or gas.
9. What is the primary cause of atherosclerosis?
A. Decreased calcium intake
B. Chronic inflammation of the blood vessels
C. Increased HDL cholesterol
D. Vitamin D deficiency
Answer: B) Chronic inflammation of the blood vessels
Rationale: Atherosclerosis is primarily caused by the build-up of
plaque in the arteries, often triggered by chronic inflammation
and high levels of LDL cholesterol in the bloodstream.
10. A nurse is assessing a client with a suspected myocardial
infarction (MI). Which finding would be most indicative of an MI?
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.
