Portage Learning – NURS 231 / BIOD 331
Human Pathophysiology | Module 7 Comprehensive Exam
Review
(LockDown Browser Compatible | 2025 Updated Edition | Verified Study Resource)
Course Overview
This Module 7 Pathophysiology Review Exam is designed to reinforce mastery of renal
physiology, fluid and electrolyte balance, and acid–base regulation. It mirrors the applied clinical
reasoning and concept-based framework used in Portage Learning’s NURS 231 / BIOD 331
courses.
Each case-based question tests comprehension, application, and interpretation of laboratory and
clinical findings.
Rationales are provided to deepen understanding and support retention of critical nursing and
biological concepts.
Exam Focus Areas
Renal Function & Disorders: Glomerular filtration, acute and chronic kidney disease,
nephrotic/nephritic syndromes
Fluid & Electrolyte Balance: Distribution of body fluids, osmolality control,
sodium/potassium/calcium regulation
Acid–Base Regulation: ABG interpretation, metabolic and respiratory compensation
Endocrine Regulation: RAAS, ADH, ANP, aldosterone, and diuretic mechanisms
Clinical Correlation: Edema, dehydration, dialysis, and uremic manifestations
Exam Format
Total Questions: 40 (Multiple Choice and Case-Based)
Answer Key: All correct responses highlighted in bold green
Rationales: Concise, evidence-based explanations for every question

, Section I – Renal Function and Disorders
1. A patient with glomerulonephritis is most likely to present with which abnormal
urine finding?
Proteinuria
Rationale: Inflammation of the glomeruli increases permeability, allowing
proteins to leak into urine.
2. Which laboratory value best reflects glomerular filtration rate (GFR)?
Serum creatinine
Rationale: Creatinine is produced at a constant rate and filtered through the
kidneys, making it a reliable indicator of renal function.
3. The renin–angiotensin–aldosterone system (RAAS) primarily acts to:
Increase blood pressure and blood volume
Rationale: Renin triggers the conversion of angiotensinogen to angiotensin II,
which causes vasoconstriction and stimulates aldosterone secretion for sodium and
water retention.
4. A patient with nephrotic syndrome typically exhibits which combination of
findings?
Generalized edema and hypoalbuminemia
Rationale: Loss of plasma proteins in urine decreases oncotic pressure, leading to
systemic edema.
5. Obstruction of the urinary tract can lead to:
Hydronephrosis
Rationale: Urine buildup from obstruction dilates renal pelvis and calyces,
damaging renal tissue.
