NUR-631 Actual Final Exam Study Guide – Comprehensive
Pathophysiology Review 500+ Questions with Answers &
Rationales Latest Update This Year | Pdf
Prepare for the NUR-631 Final Exam with a comprehensive study resource designed to help
nursing students review high-yield pathophysiology concepts and strengthen clinical reasoning
before the final assessment.
This guide brings together major disease processes, physiological alterations, clinical
manifestations, and system-based concepts into one organized review. It is useful for identifying
areas that need additional study and reinforcing connections between pathophysiology, patient
findings, and clinical presentation.
What This Study Guide Covers
Cellular & Genetic Concepts – Cellular adaptation, injury, inflammation, genetics, and
disease mechanisms.
Immune & Inflammatory Disorders – Immune responses, hypersensitivity,
autoimmune conditions, and inflammatory processes.
Cardiovascular Pathophysiology – Hypertension, cardiac dysfunction, vascular
disorders, circulation, and related complications.
Respiratory Disorders – Ventilation, perfusion, gas exchange, obstructive and
restrictive disorders, and respiratory dysfunction.
Renal & Urinary Disorders – Kidney function, fluid balance, electrolyte regulation,
renal injury, and urinary conditions.
Endocrine & Metabolic Disorders – Hormonal regulation, endocrine dysfunction,
diabetes, and metabolic disturbances.
Neurological Disorders – Nervous-system dysfunction, neurological disease processes,
and associated clinical manifestations.
Gastrointestinal & Hepatic Disorders – GI dysfunction, liver disease, digestion,
absorption, and systemic effects.
Hematologic Disorders – Anemia, blood-cell abnormalities, coagulation disorders, and
related pathophysiology.
Musculoskeletal & Systemic Conditions – Disorders affecting bones, joints, connective
tissues, and multiple body systems.
Clinical Manifestations & Reasoning – Connecting underlying disease mechanisms
with signs, symptoms, and patient findings.
,Which hormone is required for water to be reabsorbed in the distal tubule and
collecting duct?
a. Antidiuretic hormone
b. Aldosterone
c. Cortisol
d. Adrenocorticotropin hormone
a. Antidiuretic hormone
Exp: Antidiuretic hormone is required for water to be reabsorbed in the distal tubule and
collecting duct. The later, straight segment of the distal tubule and the collecting duct are
permeable to water as controlled by antidiuretic hormone. The other options are not
involved in this process. page 1331
The concentration of the final urine is determined by antidiuretic hormone (ADH),
which is secreted by which gland?
a. Posterior pituitary
b. Thyroid
c. Parathyroid
d. Anterior pituitary
a. Posterior pituitary
Exp: ADH which is secreted from the posterior pituitary gland, controls the concentration of
the final urine. Pages 1332 and 1333
,What is the most common cause of uncomplicated urinary tract infections?
a. Staphylococcus
b. Klebsiella
c. Proteus
d. Escherichia coli
d. Escherichia coli ; The most common infecting microorganisms are uropathic strains of E.
coli (80% to 85%). page 1350
Which clinical manifestations of a urinary tract infection may be demonstrated in an
85-year-old individual?
a. Confusion and poorly localized abdominal discomfort
b. Dysuria, frequency, and suprapubic pain
c. Hematuria and flank pain
d. Pyuria, urgency, and frequency
a. Confusion and poorly localized abdominal discomfort
Exp: Older adults with cystitis may demonstrate confusion or vague abdominal discomfort or
otherwise be asymptomatic. page 1351
Pyelonephritis is usually caused by which type of organism?
a. Bacteria
b. Fungi
c. Viruses
d. Parasite
, a. Bacteria
Exp: Pyelonephritis is usually caused by the bacteria Escherichia coli, Proteus, or
Pseudomonas. pages 1351-52
A patient exhibits symptoms including hematuria with red blood cell casts and
proteinuria exceeding 3 to 5 g/ day with albumin as the major protein. These data
suggest the presence of which disorder?
a. Cystitis
b. Chronic pyelonephritis
c. Glomerulonephritis
d. Nephrotic syndrome
c. Glomerulonephritis
Exp: The data suggest the patient has the disorder known as glomerulonephritis. Two major
changes distinctive of more severe glomerulonephritis are (1) hematuria with red blood cell
casts and (2) proteinuria exceeding 3-5 g/ day with albumin as the major protein. These
symptoms do not support the diagnosis of the other options. page 1357
How are glucose and insulin used to treat hyperkalemia associated with acute renal
failure?
a. Glucose has an osmotic effect, which attracts water and sodium resulting in more
dilute blood and a lower potassium concentration.
b. When insulin transports glucose into the cell, it also carries potassium with it.
c. Potassium attaches to receptors on the cell membrane of glucose and is carried
into the cell.
d. Increasing insulin causes ketoacidosis, which causes potassium to move into the
cell in exchange for hydrogen
