NIGHTINGALE PATHOPHYSIOLOGY FINAL 2026 ACTUAL EXAM (TESTING REAL
EXAM QUESTIONS) AND VERIFIED ANSWERS ( 100% ACCURATE) GET IT
RIGHT!!
Question 1
A patient with type 1 diabetes mellitus asks the nurse what causes polyuria. What is the nurse's
best response?
A) Increased protein in the blood
B) Decreased glomerular filtration rate
C) Increased glucose in the urine
D) Excessive intake of dietary sodium
E) Decreased production of aldosterone
Correct Answer: C) Increase glucose in Urine
Rationale: Hyperglycemia leads to glucose levels exceeding the renal threshold. This causes
glucose to be excreted in the urine (glycosuria), which acts as an osmotic diuretic, pulling
water with it and resulting in polyuria.
Question 2
If a patient with diabetes has advanced glycosylation end products (AGEs), what does the nurse
suspect is happening in the patient's body?
A) Rapid weight gain
B) Tissue and cellular injury
C) Enhanced insulin sensitivity
D) Regeneration of pancreatic beta cells
E) Improvement in peripheral nerve conduction
Correct Answer: B) Tissue/ cellular injury
Rationale: AGEs result from irreversible binding of glucose to proteins and lipids. This
process triggers inflammation, oxidative stress, and basement membrane thickening,
leading to the chronic microvascular and macrovascular complications of diabetes.
Question 3
Which information should the nurse include in a lecture on Syndrome of Inappropriate
Antidiuretic Hormone (SIADH)?
A) Excessive renal excretion of sodium and water
B) Excessive renal retention of water without sodium retention
C) Increased serum osmolality and hypernatremia
D) Inability of the kidneys to concentrate urine
E) Damage to the adrenal cortex resulting in low cortisol
Correct Answer: B) renal retention of water without sodium retention.
Rationale: SIADH involves high levels of ADH, which causes the kidneys to reabsorb
excessive amounts of water into the bloodstream. This leads to dilutional hyponatremia and
fluid volume overload.

Question 4
A patient with Graves' disease has subcutaneous swelling of the anterior leg. Which term should
the nurse document on the chart?
A) Pitting edema
B) Lymphedema
C) Pretibial myxedema
D) Peripheral neuropathy
E) Raynaud’s phenomenon
Correct Answer: C) Pretibial myxedema
Rationale: Pretibial myxedema is a cutaneous manifestation of Graves' disease caused by
the accumulation of glycosaminoglycans in the dermis, typically presenting as thickened,
red skin on the shins.
Question 5
A student nurse asks the nurse what causes acromegaly. The nurse should explain that
acromegaly is caused by abnormal increases of:
A) Thyroid stimulating hormone
B) Adrenocorticotropic hormone
C) Growth hormone
D) Antidiuretic hormone
E) Luteinizing hormone
Correct Answer: C) Growth hormone
Rationale: Acromegaly occurs due to excessive growth hormone (GH) secretion after the
epiphyseal plates have closed, usually resulting from a pituitary adenoma. This causes
enlargement of bones in the face, hands, and feet.
Question 6
The pathophysiology of type 1 diabetes mellitus (DM) involves:
A) Insulin resistance in peripheral tissues
B) Overproduction of glucagon by alpha cells
C) Autoimmune destruction of pancreatic beta cells
D) Exhaustion of beta cells due to high carbohydrate intake
E) Impaired glucose absorption in the small intestine
Correct Answer: C) autoimmune destruction of pancreatic beta cells
Rationale: Type 1 DM is characterized by a T-cell-mediated autoimmune attack on the beta
cells of the Islets of Langerhans, leading to an absolute insulin deficiency.
Question 7
A patient has thyroid carcinoma. Which of the following will the nurse find on assessment?
A) Profuse diaphoresis and tremors
B) Large, soft, diffuse goiter
, 3
C) Small, firm thyroid nodule
D) Rapid weight loss and exophthalmos
E) Elevated serum calcium levels
Correct Answer: C) Small thyroid nodule
Rationale: Thyroid carcinoma most commonly presents as a small, painless, palpable nodule
on the thyroid gland. Most patients are euthyroid (normal thyroid function) at the time of
diagnosis.
Question 8
Which is the appropriate method for the diagnosis of type 1 diabetes?
A) Measuring urine ketones only
B) Evaluating fasting plasma glucose levels
C) Assessing the patient’s body mass index (BMI)
D) Measuring C-peptide levels after a high-fat meal
E) Assessing blood pressure and heart rate
Correct Answer: B) Evaluating fasting plasma glucose levels
Rationale: A fasting plasma glucose (FPG) ≥ 126 mg/dL on two separate occasions is a
standard diagnostic criterion for diabetes mellitus.
Question 9
Which of the following statements indicates that the nurse needs more teaching regarding
hyperglycemia and chronic complications?
A) Hyperglycemia can cause polyol pathway activation.
B) Hyperglycemia leads to the formation of AGEs.
C) Hyperglycemia can lead to chronic complications through the suppression of oxidative stress.
D) Hyperglycemia can cause protein kinase C activation.
E) Hyperglycemia increases inflammation in the vessel walls.
Correct Answer: C) suppression of oxidative stress.
Rationale: Hyperglycemia actually increases oxidative stress, which contributes to cellular
damage. It does not suppress it.
Question 10
Graves' disease is an example of which hypersensitivity reaction?
A) Type I (IgE mediated)
B) Type II (Tissue specific)
C) Type III (Immune complex)
D) Type IV (Cell mediated)
E) Delayed hypersensitivity
Correct Answer: B) Type II hypersensitivity
Rationale: Graves' disease involves autoantibodies (TSIs) that bind to the TSH receptor,
stimulating the thyroid gland. This is a tissue-specific Type II reaction.
