Practice Questions
Subject: Complex Endocrine Pathophysiology and Community Health Nursing
Question 1: A client with syndrome of inappropriate antidiuretic hormone (SIADH) secondary to
small-cell lung carcinoma is admitted with a serum sodium level of 118 mEq/L. Which clinical
manifestation is the highest priority for the nurse to monitor for, and what is the underlying
pathophysiology?
A) Peripheral edema; caused by hydrostatic pressure exceeding oncotic pressure.
B) Seizures; caused by cerebral edema resulting from intracellular fluid shift.
C) Polyuria; caused by the inhibition of aquaporin-2 channels in the collecting duct.
D) Hypertension; caused by excessive renin-angiotensin-aldosterone system activation.
Correct Answer: B) Seizures; caused by cerebral edema resulting from intracellular fluid
shift.
Explanation: In SIADH, excessive ADH causes water retention and dilutional hyponatremia. As
serum osmolality drops, water moves from the intravascular space into the intracellular space
(osmosis). In the brain, this causes cerebral edema, increasing intracranial pressure and placing
the client at high risk for seizures and neurological decline. Peripheral edema is rare because
the excess fluid is distributed intracellularly, not interstitially.
Question 2: An endocrine patient presents with a TSH level of <0.01 mIU/L, an elevated Free
T4, and a positive TSH-receptor antibody (TRAb) test. Which of the following physical
assessment findings is most consistent with this diagnosis?
A) Bradycardia and cold intolerance.
B) Periorbital edema and elevated diastolic blood pressure.
C) Exophthalmos and a localized, non-pitting edema over the anterior tibia.
D) Hypotension and hyperpigmentation of the skin folds.
Correct Answer: C) Exophthalmos and a localized, non-pitting edema over the anterior
tibia.
,Explanation: The clinical and laboratory findings are pathognomonic for Graves' disease
(hyperthyroidism). Graves' disease is an autoimmune condition where TRAbs stimulate the
thyroid gland. Associated autoimmune features include Graves' ophthalmopathy (exophthalmos)
and pretibial myxedema (localized, non-pitting edema), which are caused by fibroblast
stimulation by the same antibodies.
Question 3: A community health nurse is conducting an epidemiological study on a local
outbreak of a communicable disease. The nurse calculates the "secondary attack rate." What is
the primary purpose of this calculation?
A) To measure the total number of new cases within the entire population over a specific time.
B) To estimate the risk of transmission to susceptible individuals after exposure to a primary
case.
C) To determine the proportion of the population that is currently immune to the disease.
D) To quantify the total burden of disease in the community, including both new and existing
cases.
Correct Answer: B) To estimate the risk of transmission to susceptible individuals after
exposure to a primary case.
Explanation: The secondary attack rate measures the probability that infection occurs among
susceptible individuals within a specific group (like a household or classroom) following
exposure to a primary (index) case. It is a critical metric for understanding the contagiousness
and transmission dynamics of a pathogen within a localized cluster.
Question 4: A client with Addison’s disease is brought to the ED in "adrenal crisis" following a
viral infection. Which of the following laboratory profiles is expected?
A) Hyperkalemia, hyponatremia, and hypoglycemia.
B) Hypokalemia, hypernatremia, and hyperglycemia.
C) Hypercalcemia, hypophosphatemia, and hypernatremia.
D) Normal potassium, hypernatremia, and metabolic alkalosis.
Correct Answer: A) Hyperkalemia, hyponatremia, and hypoglycemia.
Explanation: Addison’s disease involves primary adrenal insufficiency (deficient cortisol and
aldosterone). In an adrenal crisis, the loss of mineralocorticoid (aldosterone) activity leads to
sodium wasting and potassium retention (hyperkalemia). The deficiency in cortisol leads to
impaired gluconeogenesis and increased insulin sensitivity, resulting in severe hypoglycemia.
, Question 5: A nurse is implementing a "tertiary prevention" strategy for a community cohort
diagnosed with Type 2 Diabetes. Which intervention is most appropriate?
A) Conducting a community-wide screening for high-risk individuals.
B) Implementing a public education campaign on healthy diet and exercise.
C) Initiating a diabetic retinopathy support group and specialized podiatric care.
D) Administering a community vaccination program for influenza.
Correct Answer: C) Initiating a diabetic retinopathy support group and specialized
podiatric care.
Explanation: Tertiary prevention focuses on managing existing diseases to prevent
complications, disability, or mortality. Screening (A) and health promotion (B) are primary and
secondary prevention efforts. Tertiary prevention involves rehabilitation and specialized
management of complications that have already manifested.
Question 6: In a client with Hyperparathyroidism, which compensatory mechanism or secondary
electrolyte imbalance is most likely?
A) Hypocalcemia due to renal excretion.
B) Hypophosphatemia due to increased renal phosphate excretion.
C) Hyperphosphatemia due to skeletal resorption.
D) Metabolic alkalosis due to excessive bicarbonate retention.
Correct Answer: B) Hypophosphatemia due to increased renal phosphate excretion.
Explanation: Parathyroid hormone (PTH) acts on the kidneys to increase calcium reabsorption
and increase phosphate excretion (phosphaturic effect). Therefore, hyperparathyroidism leads to
hypercalcemia and hypophosphatemia. The phosphate is dumped in the urine to maintain
electrical neutrality and prevent precipitation of calcium-phosphate stones.
Question 7: A public health official is analyzing the "epidemiological triangle" of a recent
foodborne illness outbreak. Which component represents the "Agent"?
A) The salmonella bacteria present in the contaminated poultry.
B) The restaurant environment where the food was prepared.
C) The immunocompromised status of the affected individuals.
