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. Which of the following is a typical sign of hypoglycemia?
A. Increased thirst
B. Shaking and sweating
C. Increased urination
D. Elevated blood pressure
Answer: B) Shaking and sweating
Rationale: Hypoglycemia causes symptoms such as shaking,
sweating, and confusion due to the body's response to low blood
sugar levels.
3. A patient with a diagnosis of schizophrenia may experience
which of the following symptoms?
A. Auditory hallucinations
B. Extreme fatigue
C. Increased blood pressure
D. Chronic cough
Answer: A) Auditory hallucinations
Rationale: Schizophrenia is often associated with psychotic
symptoms, including auditory hallucinations, delusions, and
disorganized thinking.
,4. 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.
5. 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.
6. What is the primary cause of osteoarthritis?
A. Autoimmune reaction
B. Wear and tear on the joints
C. Bacterial infection
D. Vitamin D deficiency
Answer: B) Wear and tear on the joints
Rationale: Osteoarthritis is primarily caused by the degeneration
of cartilage due to repetitive use or aging, leading to joint pain
and stiffness.
7. 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.
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 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.
10. 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)
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).
