1. 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.
2. 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.
3. 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.
,4. What is the most common cause of peptic ulcers?
A. Stress
B. Use of nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Helicobacter pylori infection
D. Excessive alcohol consumption
Answer: C) Helicobacter pylori infection
Rationale: H. pylori infection is the leading cause of peptic ulcers
due to its ability to disrupt the mucosal lining of the stomach.
5. 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.
6. 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.
7. Which of the following is the primary treatment goal for a
patient with acute myocardial infarction (MI)?
, A. Increase fluid intake
B. Reduce heart rate and oxygen demand
C. Prevent deep vein thrombosis
D. Enhance gastrointestinal function
Answer: B) Reduce heart rate and oxygen demand
Rationale: The primary goal in managing MI is to reduce the
heart's workload by decreasing heart rate and oxygen demand to
prevent further damage to the heart muscle.
8. 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).
9. 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.
