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 presents with a chronic cough, wheezing, and
shortness of breath. Which condition should the nurse suspect?
A. Bronchitis
B. Emphysema
C. Asthma
D. Pulmonary embolism
Answer: C) Asthma
Rationale: Asthma is characterized by inflammation and
constriction of the airways, leading to symptoms like chronic
cough, wheezing, and difficulty breathing.
3. Which of the following would you expect in a patient with
Addison’s disease?
A. Increased blood pressure
B. Hyperkalemia
C. Weight gain
D. Increased appetite
Answer: B) Hyperkalemia
Rationale: Addison’s disease, a disorder of the adrenal glands,
leads to decreased cortisol and aldosterone production. This
,results in fluid and sodium loss and potassium retention, causing
hyperkalemia.
4. 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).
5. What is the most common cause of secondary hypertension?
A. Excessive salt intake
B. Renal disease
C. High cholesterol levels
D. Alcohol consumption
Answer: B) Renal disease
Rationale: Secondary hypertension is often caused by another
condition, with renal disease being a leading factor due to
impaired kidney function affecting fluid balance and blood
pressure regulation.
6. 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.
7. 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.
8. 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.
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
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.
