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 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. 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. A nurse is caring for a patient with pneumonia. Which of the
,following is a common sign of pneumonia?
A. Cough with sputum production
B. Sudden weight gain
C. Seizures
D. Hemoptysis without cough
Answer: A) Cough with sputum production
Rationale: Pneumonia typically presents with symptoms such as a
productive cough with purulent sputum, fever, and difficulty
breathing due to inflammation in the lungs.
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. A patient with hypothyroidism is most likely to have which of
the following symptoms?
A. Weight loss
B. Increased heart rate
C. Cold intolerance
D. Heat intolerance
Answer: C) Cold intolerance
Rationale: Hypothyroidism leads to reduced metabolism, causing
symptoms such as cold intolerance, weight gain, and fatigue.
7. 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.
8. What is the primary cause of atherosclerosis?
A. Decreased calcium intake
B. Chronic inflammation of the blood vessels
C. Increased HDL cholesterol
D. Vitamin D deficiency
Answer: B) Chronic inflammation of the blood vessels
Rationale: Atherosclerosis is primarily caused by the build-up of
plaque in the arteries, often triggered by chronic inflammation
and high levels of LDL cholesterol in the bloodstream.
9. What is a classic symptom of Parkinson’s disease?
A. Muscle rigidity
B. Hypotension
C. Polyuria
D. Weight gain
Answer: A) Muscle rigidity
Rationale: Parkinson’s disease is characterized by symptoms such
as muscle rigidity, tremors, and bradykinesia due to a loss of
dopaminergic neurons in the brain.
10. 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
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.
