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. Which of the following would most likely cause a decrease in
blood pressure?
A. Activation of the sympathetic nervous system
B. Release of aldosterone
C. Release of antidiuretic hormone (ADH)
D. Decreased blood volume
Answer: D) Decreased blood volume
Rationale: Decreased blood volume reduces venous return, leading
to reduced cardiac output and a drop in blood pressure.
3. 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.
,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. 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.
6. 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.
, 7. A patient with acute bacterial meningitis is likely to experience
which of the following?
A. Increased thirst and urination
B. Severe headache and neck stiffness
C. Joint pain and swelling
D. Abdominal pain and bloating
Answer: B) Severe headache and neck stiffness
Rationale: Acute bacterial meningitis causes inflammation of the
meninges, leading to symptoms like severe headache, neck
stiffness, photophobia, and fever.
8. 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.
9. 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).
polydipsia, and weight loss. What condition might these
