1. A patient with diabetes mellitus presents with polyuria,
polydipsia, and weight loss. What condition might these
symptoms indicate?
A. Diabetic ketoacidosis (DKA)
B. Hyperosmolar hyperglycemic state (HHS)
C. Hypoglycemia
D. Hypertension
Answer: A) Diabetic ketoacidosis (DKA)
Rationale: DKA occurs when insulin deficiency causes increased
glucose production and fat breakdown, leading to ketosis and
elevated blood glucose levels, which cause symptoms like
polyuria, polydipsia, and weight loss.
2. 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.
3. A patient presents with fever, jaundice, and dark urine. Which
condition might this indicate?
A. Hepatitis
B. Gallstones
C. Pancreatitis
D. Cirrhosis
Answer: A) Hepatitis
,Rationale: Hepatitis can lead to liver inflammation, resulting in
jaundice (yellowing of the skin), dark urine, and fever.
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. A patient with a diagnosis of systemic lupus erythematosus
(SLE) is at increased risk for which of the following?
A. Infection
B. Weight loss
C. Hyperthyroidism
D. Stroke
Answer: A) Infection
Rationale: SLE is an autoimmune disorder that affects the immune
system, leaving the patient at higher risk for infections due to
immunosuppressive therapy and the disease itself.
6. 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.
7. Which of the following is a classic sign of hyperthyroidism?
A. Weight gain
B. Cold intolerance
C. Tachycardia
D. Bradycardia
Answer: C) Tachycardia
Rationale: Hyperthyroidism is characterized by an overproduction
of thyroid hormones, leading to symptoms like tachycardia, heat
intolerance, and weight loss.
8. Which of the following factors is most likely to increase the
risk of deep vein thrombosis (DVT)?
A. Frequent physical activity
B. Use of oral contraceptives
C. Low body weight
D. Dehydration
Answer: B) Use of oral contraceptives
Rationale: Oral contraceptives can increase clotting factor
production, which elevates the risk of DVT.
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. What is the primary cause of osteoarthritis?
polydipsia, and weight loss. What condition might these
symptoms indicate?
A. Diabetic ketoacidosis (DKA)
B. Hyperosmolar hyperglycemic state (HHS)
C. Hypoglycemia
D. Hypertension
Answer: A) Diabetic ketoacidosis (DKA)
Rationale: DKA occurs when insulin deficiency causes increased
glucose production and fat breakdown, leading to ketosis and
elevated blood glucose levels, which cause symptoms like
