1. 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).
2. 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.
3. 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.
4. A patient with acute blood loss from a traumatic injury may
experience which of the following?
A. Decreased heart rate
B. Decreased respiratory rate
C. Increased blood pressure
D. Increased heart rate
Answer: D) Increased heart rate
Rationale: Acute blood loss leads to a decrease in circulating
blood volume, which triggers compensatory tachycardia
(increased heart rate) to maintain cardiac output.
5. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
D. Hypertension
Answer: B) Ischemia due to a clot
Rationale: Ischemic strokes are the most common type of stroke
and occur when a clot blocks blood flow to the brain.
6. Which of the following is a common cause of hypoxemia?
A. Anemia
B. Asthma
C. Hypertension
D. Diabetes
Answer: B) Asthma
Rationale: Asthma causes bronchoconstriction and inflammation
in the airways, leading to decreased oxygen exchange and
resulting in hypoxemia.
, 7. 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.
8. What is a common sign of a urinary tract infection (UTI) in
older adults?
A. Fever and chills
B. Confusion and delirium
C. Painful urination
D. Excessive thirst
Answer: B) Confusion and delirium
Rationale: In older adults, UTIs may present with atypical
symptoms such as confusion, delirium, or agitation, rather than
the typical symptoms of fever and dysuria.
9. 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.
