1. 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.
2. 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.
3. What is the main cause of type 2 diabetes?
A. Insulin resistance
B. Insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: A) Insulin resistance
Rationale: Type 2 diabetes is primarily caused by insulin
resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
4. 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.
5. 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).
6. 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.
7. 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.
8. A patient with cirrhosis has developed ascites. Which of the
following is a likely cause of ascites in this patient?
A. Decreased albumin production
B. Increased clotting factors
C. Increased renin production
D. Decreased red blood cell production
Answer: A) Decreased albumin production
Rationale: In cirrhosis, the liver's ability to produce albumin is
impaired, leading to a decrease in plasma oncotic pressure, which
contributes to fluid accumulation in the abdomen (ascites).
9. 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.
10. Which of the following is a classic sign of hyperthyroidism?
A. Weight gain
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.
