NURS 618 LATEST MULTIPLE CHOICE QUESTIONS
BANK WITH RATIONALES A+ STUDY GUIDE FOR
PATHOPHYSIOLOGY
Master your NURS 618 Pathophysiology course with this
extensive question bank covering rigorously developed multiple-
choice questions. Each question includes the correct answer in
italics and a detailed rationale in bold italics, providing instant
feedback and deep understanding of complex disease processes.
Ideal for exam preparation, this guide guarantees a
comprehensive review of key topics, ensuring you are fully
prepared for any assessment.
1. A patient presents with a sudden onset of
severe chest pain that radiates to the back. The
pain is described as a "tearing" sensation. The
patient's blood pressure is significantly different
between the right and left arms. Which of the
following is the most likely diagnosis?
A) Myocardial Infarction
B) Pulmonary Embolism
C) Aortic Dissection
D) Pericarditis
Rationale: *Aortic dissection presents with a
classic "tearing" or "ripping" chest pain that
often radiates to the back. A key clinical finding
is a difference in blood pressure between the
arms due to the dissection compromising flow
into branch vessels. Myocardial infarction pain is
,typically pressure-like or crushing, pulmonary
embolism causes pleuritic pain and sudden
dyspnea, and pericarditis pain is sharp and
positional. *
2. In the pathophysiology of asthma, which of
the following mediators is primarily responsible
for the early-phase bronchospasm?
A) Leukotrienes
B) Histamine
C) Prostaglandin D2
D) IgE-mediated mast cell degranulation
Rationale: *The early-phase asthmatic response
(within minutes) is triggered by the cross-linking
of IgE antibodies on the surface of mast cells,
leading to degranulation and the release of
preformed mediators like histamine.
Leukotrienes and prostaglandins are released in
both early and late phases, but the initial
bronchospasm is a direct result of mast cell
degranulation. *
3. A patient with type 1 diabetes mellitus is
brought to the emergency department with deep,
,rapid respirations, a fruity odor on their breath,
and confusion. Which of the following acid-base
imbalances is most likely?
A) Metabolic Alkalosis
B) Metabolic Acidosis
C) Respiratory Acidosis
D) Respiratory Alkalosis
Rationale: *The scenario describes diabetic
ketoacidosis (DKA), a complication of type 1
diabetes. The lack of insulin leads to the
breakdown of fats, producing ketone bodies
(acids), causing a metabolic acidosis. The deep,
rapid respirations (Kussmaul respirations) are a
compensatory mechanism to blow off CO2, and
the fruity breath is from acetone, a ketone
body. *
4. In the renin-angiotensin-aldosterone system
(RAAS), which of the following is the primary
stimulus for renin release?
A) Increased serum sodium levels
B) Increased blood pressure in the afferent arteriole
C) Decreased blood flow to the juxtaglomerular
apparatus
D) Increased plasma volume
, Rationale: *The juxtaglomerular (JG) cells in the
kidney are baroreceptors that sense a decrease
in blood pressure or blood flow. This is the
primary stimulus for renin release. Other stimuli
include decreased sodium delivery to the macula
densa and sympathetic nervous system
stimulation. Increased sodium, pressure, or
volume would inhibit renin release. *
5. Which of the following is a hallmark
characteristic of malignant neoplasms?
A) Well-differentiated cells
B) Slow growth rate
C) Invasion and metastasis
D) Encapsulated by fibrous tissue
Rationale: *Malignant tumors are characterized
by anaplasia (poor differentiation), rapid and
uncontrolled growth, local invasion, and the
ability to metastasize to distant sites. Benign
tumors are usually well-differentiated, slow-
growing, and encapsulated. *
6. A patient with chronic kidney disease (CKD)
develops anemia. This is primarily due to a
