1. 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.
2. 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.
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. Which of the following is a classic sign of hyperthyroidism?
A. Weight gain
B. Cold intolerance
C. Tachycardia
D. Bradycardia
Answer: C) Tachycardia
Rationale: Hyperthyroidism is characterized by an overproduction
of thyroid hormones, leading to symptoms like tachycardia, heat
intolerance, and weight loss.
5. Which of the following is a primary complication of untreated
hypertension?
A. Diabetes
B. Stroke
C. Asthma
D. Hyperthyroidism
Answer: B) Stroke
Rationale: Untreated hypertension can cause damage to blood
vessels, increasing the risk of a stroke due to the development of
atherosclerosis or rupture of a weakened vessel.
6. 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.
7. A patient with a history of chronic pancreatitis is at increased
, risk for which of the following complications?
A. Diabetes mellitus
B. Hypoglycemia
C. Hyperkalemia
D. Asthma
Answer: A) Diabetes mellitus
Rationale: Chronic pancreatitis can damage the pancreas' ability
to secrete insulin, leading to insulin resistance and an increased
risk of diabetes mellitus.
8. A patient with chronic kidney disease (CKD) is most at risk for
which of the following electrolyte imbalances?
A. Hyperkalemia
B. Hypokalemia
C. Hypercalcemia
D. Hypocalcemia
Answer: A) Hyperkalemia
Rationale: In CKD, the kidneys are unable to excrete potassium
effectively, leading to the accumulation of potassium in the blood,
resulting in hyperkalemia.
9. 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.
