PORTAGE PATHOPHYSIOLOGY MODULE 9
EXAM 300 ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST UPDATE
ALREADY GRADED A+
The Portage Pathophysiology Module 9 Exam is a specialized assessment
focused on endocrine system disorders, typically administered in nursing and
pre-health programs such as NURS 231 or BIOD 331 at Portage Learning.
This module-based, proctored exam evaluates students' understanding of
hormonal regulation, glandular function, and the pathophysiology of
conditions including diabetes mellitus, thyroid disorders, Cushing's syndrome,
Addison's disease, and adrenal insufficiencies. The exam emphasizes clinical
application, asking students to analyze signs and symptoms, interpret
laboratory values, identify complications, and understand treatment
mechanisms. Mastery of endocrine physiology is essential for success, as the
exam integrates complex feedback mechanisms, hormone interactions, and
disease progression, preparing students for clinical practice and licensure
examinations.
1. What syndrome has an increased production of glucocorticoids?
A) Addison's disease
B) Cushing's syndrome
C) Graves' disease
D) Hashimoto's thyroiditis
Correct Answer: B
Rationale: Cushing's syndrome is characterized by excessive production of
glucocorticoids (cortisol) from the adrenal cortex. This can result from a pituitary
adenoma (Cushing's disease), adrenal tumors, or prolonged exogenous
corticosteroid use .
2. The following are common signs and symptoms of Cushing syndrome
EXCEPT:
A) Weight gain
B) Hyperglycemia
,C) Hypotension
D) Purple striae
Correct Answer: C
Rationale: Cushing's syndrome presents with hypertension due to
mineralocorticoid effects, not hypotension. Other classic features include weight
gain, hyperglycemia, moon facies, buffalo hump, and purple striae from protein
breakdown .
3. Signs and symptoms of Addison's disease include each of the following
EXCEPT:
A) Hyperpigmentation
B) Hypotension
C) Weight loss
D) Hyperglycemia
Correct Answer: D
Rationale: Addison's disease is chronic adrenal insufficiency causing decreased
cortisol and aldosterone, leading to hypotension, weight loss, and
hyperpigmentation from elevated ACTH. Hypoglycemia is common due to
deficient gluconeogenesis, not hyperglycemia .
4. Addison's disease is due to which of the following?
A) Thyroid dysfunction
B) Pituitary dysfunction
C) Adrenal gland dysfunction
D) Pancreatic dysfunction
Correct Answer: C
Rationale: Addison's disease (primary adrenal insufficiency) results from
dysfunction of the adrenal cortex itself, leading to deficiencies in cortisol and
aldosterone production. Pituitary dysfunction causes secondary adrenal
insufficiency .
5. An endocrine hormone is released into circulation to act on a target organ.
A) True
B) False
Correct Answer: A
Rationale: Endocrine hormones are secreted directly into the bloodstream and
travel through the circulation to reach and act on distant target organs. This is the
classic mechanism of endocrine signaling .
,6. A paracrine action occurs when a hormone exerts an action on the cells that
produced it.
A) True
B) False
Correct Answer: B
Rationale: Paracrine action refers to hormones acting on nearby cells close to
where they are released, not the cells that produced them. Autocrine action is when
a hormone acts on the cell that released it .
7. Target cells must have receptors to recognize a hormone and translate the signal
into a cellular response.
A) True
B) False
Correct Answer: A
Rationale: Target cells possess specific receptors that bind hormones with high
affinity. The receptor-hormone complex initiates intracellular signaling cascades
that produce the cellular response. Without receptors, cells cannot respond to
hormones .
8. Hormones travel through the bloodstream attached to transport carriers only.
A) True
B) False
Correct Answer: B
Rationale: While many hormones (especially steroid and thyroid hormones) travel
bound to transport carriers, others (like peptide hormones) circulate freely in the
bloodstream. Hormones can travel either bound or unbound .
9. What is the source of the hormone that plays a major role in the maintenance of
body metabolism and growth and development in children?
A) Adrenal gland
B) Pituitary gland
C) Thyroid gland
D) Pancreas
Correct Answer: C
Rationale: Thyroid hormones (T3, T4) are essential for normal growth,
neurological development, and maintenance of metabolic rate in children. Thyroid
disorders can result in intellectual disability and growth retardation if untreated .
10. The posterior pituitary releases which of the following hormones? Select all
that apply.
, A) Prolactin
B) Oxytocin
C) ADH (Vasopressin)
D) Growth hormone
Correct Answer: B, C
Rationale: The posterior pituitary releases oxytocin (involved in uterine contraction
and milk ejection) and antidiuretic hormone (ADH), which regulates water
reabsorption. Prolactin and growth hormone are secreted by the anterior pituitary .
11. Type 1 diabetes mellitus is associated with each of the following characteristics
EXCEPT:
A) Autoimmune destruction of beta cells
B) Absolute insulin deficiency
C) Gradual, subtle onset
D) Ketoacidosis risk
Correct Answer: C
Rationale: Type 1 diabetes has an abrupt, acute onset, often presenting with severe
symptoms like ketoacidosis. It results from autoimmune destruction of pancreatic
beta cells leading to absolute insulin deficiency .
12. Each of the following are characteristics of diabetes mellitus except:
A) Polyuria
B) Polydipsia
C) Polyphagia
D) Myxedema
Correct Answer: D
Rationale: The classic triad of diabetes mellitus is polyuria, polydipsia, and
polyphagia. Myxedema is associated with hypothyroidism, not diabetes mellitus .
13. Glycogenesis means glucose formation.
A) True
B) False
Correct Answer: B
Rationale: Glycogenesis is the process of glycogen formation (storing glucose), not
glucose formation. Gluconeogenesis is the formation of glucose from non-
carbohydrate sources .
14. When the body is in starvation mode, it breaks down fat into ketones.
A) True
B) False
