1. A patient with chronic kidney disease (CKD) is most at risk for
which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypocalcemia
Answer: A) Hyperkalemia
Rationale: In CKD, the kidneys are unable to excrete potassium
effectively, leading to the accumulation of potassium in the blood,
resulting in hyperkalemia.
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 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.
,4. What is a common complication of untreated hyperthyroidism?
A. Heart failure
B. Bradycardia
C. Hypoglycemia
D. Myxedema coma
Answer: A) Heart failure
Rationale: Untreated hyperthyroidism can lead to tachycardia and
increased cardiac workload, which can eventually result in heart
failure.
5. 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.
6. 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.
7. 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.
8. 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).
9. Which electrolyte imbalance is most commonly associated with
chronic alcoholism?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypomagnesemia
Answer: D) Hypomagnesemia
Rationale: Chronic alcoholism leads to malabsorption of nutrients,
including magnesium, resulting in hypomagnesemia.
10. What is a common sign of a urinary tract infection (UTI) in
which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypocalcemia
Answer: A) Hyperkalemia
Rationale: In CKD, the kidneys are unable to excrete potassium
effectively, leading to the accumulation of potassium in the blood,
resulting in hyperkalemia.
