ADVANCED PRACTICE NURSE EXAM
PREPARATION PACK 2026 KEY CONCEPTS
AND REVISION NOTES
◉ Peroxisomes. Answer: are involved in the impairment of cellular
functions when their function is compromised.
◉ Protein synthesis. Answer: involves copying and carrying DNA
instructions.
◉ Calcium bonds. Answer: are stored in mitochondria for muscle
contractions.
◉ Cell gap junctions. Answer: accumulate chemical messengers for
effective signaling.
◉ Ion channel neurotransmission. Answer: is responsible for
generating and conducting membrane potentials.
◉ Collagen. Answer: is synthesized by fibroblasts in connective
tissue.
,◉ Cellular debris. Answer: is removed by exocytosis.
◉ ATP. Answer: is involved in aerobic metabolism by having its
phosphate bonds removed.
◉ Inability to transport cellular products. Answer: an inability to
transport cellular products across the cell membrane.
◉ Insufficient energy production. Answer: insufficient energy
production within a cell.
◉ Accumulation of free radicals. Answer: accumulation of free
radicals in the cytoplasm.
◉ Decreased sperm motility. Answer: a finding that is thought to
underlie the couples inability to become pregnant.
◉ Defective cellular components in sperm. Answer: Ribosomes,
Microtubules, Mitochondria, Microfilaments.
◉ True statement of glycolysis. Answer: Glycolysis occurs in cells
without mitochondria.
,◉ Membrane transport mechanisms energy requirement. Answer:
Vesicular transport requires the greatest amount of energy.
◉ Glucose transport in diabetes. Answer: Facilitated diffusion would
best allow glucose to cross cell membranes.
◉ True statements about skeletal muscle cells. Answer: Skeletal
muscle is multinucleated, lacking true cell boundaries.
◉ Body tissues with highest turnover rate. Answer: The squamous
epithelial cells of the skin.
◉ Pathophysiologic condition affecting desmosomes. Answer:
separation at the junctions between epithelial cells.
◉ Innate immunity. Answer: mechanisms that respond specifically
to microbes.
◉ Adaptive immune responses. Answer: composed of lymphocytes
and their products.
◉ Effector cells of the immune system. Answer: eliminating the
antigens.
, ◉ Activation of lymphocytes dependency. Answer: dependent upon
the processing and presentation of the antigens by macrophages.
◉ Major histocompatibility complex (MHC). Answer: markers on all
nucleated cells that have an important role in avoiding transplant
rejections.
◉ Role of dendritic cells. Answer: important for initiation of
adaptive immunity.
◉ T helper cells. Answer: Cells that secrete cytokines that activate
and regulate nearly all of the other cells of the immune system.
◉ Cytokines. Answer: Signaling molecules that mediate and regulate
immunity, inflammation, and hematopoiesis.
◉ IgM. Answer: The first circulating immunoglobulin to appear in
response to a new antigen.
◉ Complement system. Answer: A group of proteins that enhance
the ability of antibodies and phagocytic cells to clear pathogens.
◉ Opsonization. Answer: The process of coating a microbe to aid
phagocyte recognition.
