Introduction
This comprehensive assessment is designed to prepare graduate nursing students for the Advanced
Pathophysiology HESI Final Examination. The questions evaluate foundational cellular mechanisms, genetic
principles, and complex systemic pathophysiologic processes. The exam is structured to assess clinical judgment
and decision-making skills through multiple-choice questions and clinical scenarios. Each question emphasizes the
application of pathophysiologic knowledge to real-world patient care, focusing on disease mechanisms, clinical
manifestations, and therapeutic implications. This resource is intended to ensure exam readiness and reinforce
critical thinking necessary for advanced nursing practice.
,SECTION ONE: QUESTIONS 1-100
1. A student is observing a cell under a microscope and notes the presence of supercoiled DNA with
histones. Which of the following structures would also be observed in this type of cell?
A. A single circular chromosome
B. Free-floating nuclear material
C. A nucleus
D. No organelles
🟢 C. A nucleus
🔴 RATIONALE: The presence of supercoiled DNA with histones is a hallmark of eukaryotic cells. Eukaryotic cells
are characterized by a membrane-bound nucleus that contains their genetic material, unlike prokaryotic cells
which lack a nucleus and have free-floating DNA . Therefore, a nucleus would also be observed.
2. A nurse is explaining the cellular function of respiration to a group of students. Which description best
defines this process?
A. The cell's ability to synthesize new substances and secrete them.
B. The ability of the cell to maintain a steady dynamic state.
C. The cell's ability to absorb oxygen and transform nutrients into energy.
D. The ability of the cell to take in nutrients for metabolism.
🟢 C. The cell's ability to absorb oxygen and transform nutrients into energy.
,🔴 RATIONALE: Respiration is the cellular function where cells absorb oxygen and use it to convert nutrients
into energy . This process is fundamental for generating ATP to power cellular activities.
3. In a eukaryotic cell, most of the genetic information, including a large amount of ribonucleic acid, is
contained in which region?
A. Mitochondria
B. Nucleolus
C. Cytoplasm
D. Ribosome
🟢 B. Nucleolus
🔴 RATIONALE: The nucleolus, located within the nucleus, is the region containing the cell's genetic material, a
large amount of RNA, DNA, and DNA-binding proteins .
4. A patient has been diagnosed with a condition caused by a disturbance in cellular respiration. Which
organelle is most likely involved in this dysfunction?
A. Lysosome
B. Ribosome
C. Mitochondria
D. Golgi apparatus
🟢 C. Mitochondria
🔴 RATIONALE: Mitochondria are the primary site of cellular respiration, where oxidative phosphorylation
occurs to produce ATP. Dysfunction in this organelle would directly impair the cell's ability to generate energy .
, 5. Which of the following cellular proteins can be removed from the cell's bilayer by dissolving the layer
itself?
A. Glycoproteins
B. Peripheral membrane proteins
C. Integral membrane proteins
D. Cell adhesion molecules
🟢 C. Integral membrane proteins
🔴 RATIONALE: Integral membrane proteins are embedded within the lipid bilayer. They can be removed only
by agents that disrupt the phospholipid bilayer itself, as they are directly attached to the membrane's
hydrophobic core .
6. During a patient's workup for anemia, the nurse reviews the laboratory results. What substance is
produced by the kidneys and stimulates red blood cell production?
A. Hepcidin
B. Erythropoietin
C. Thrombopoietin
D. Renin
🟢 B. Erythropoietin
🔴 RATIONALE: Erythropoietin is a hormone produced primarily by the kidneys in response to hypoxia. It
stimulates the bone marrow to increase the production of red blood cells, a process known as erythropoiesis.
