1. 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.
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. What condition is characterized by the failure of the heart to
pump effectively, leading to inadequate tissue perfusion?
A. Stroke
B. Coronary artery disease (CAD)
C. Heart failure
D. Hypertension
Answer: C) Heart failure
Rationale: Heart failure occurs when the heart is unable to pump
blood efficiently, leading to reduced perfusion of tissues and
organs.
,4. A patient has been diagnosed with tuberculosis (TB). Which of
the following is the most common symptom?
A. Night sweats
B. Joint pain
C. Hematuria
D. Abdominal pain
Answer: A) Night sweats
Rationale: Night sweats are a classic symptom of tuberculosis,
along with cough and weight loss.
5. What is a key characteristic of Crohn's disease?
A. Continuous inflammation of the colon
B. Painless, non-bloody diarrhea
C. Skip lesions along the gastrointestinal tract
D. Gallstone formation
Answer: C) Skip lesions along the gastrointestinal tract
Rationale: Crohn’s disease is characterized by inflammation that
can occur in patches (skip lesions) throughout the gastrointestinal
tract, leading to symptoms like diarrhea, abdominal pain, and
weight loss.
6. 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.
, 7. What is the main cause of type 2 diabetes?
A. Insulin resistance
B. Insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: A) Insulin resistance
Rationale: Type 2 diabetes is primarily caused by insulin
resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
8. 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.
9. 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).
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.
