ADVANCED PATHOPHYSIOLOGY QUIZ 1-NURS 6501 WALDEN UNIVERSITY | LATEST UPDATED 2026/2027 (GRADED A+)
A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance?
✔️Answer: Anaerobic glycolysis
What causes the rapid change in the resting membrane potential that initiates an action potential? ✔️Answer: Sodium gates open, and sodium
rushes into the cell, changing the membrane potential from negative to positive.
A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would reveal which of the following? ✔️Answer: XXY
A nurse is reviewing the pedigree chart. When checking for a proband, what is the nurse looking for? ✔️Answer: The person who is first
diagnosed with a genetic disease
An aide asks the nurse why people who have neurofibromatosis will show varying degrees of the disease. Which genetic principle should the
nurse explain to the aide? ✔️Answer: Expressivity
In teaching a patient with cirrhosis, which information should the nurse include regarding cholesterol? ✔️Answer: Cholesterol decreases the
membrane fluidity of the erythrocyte, which reduces its ability to carry oxygen.
A 15-year-old female is diagnosed with Prader-Willi syndrome. This condition is an example of: ✔️Answer: Gene imprinting
When a patient asks what causes cystic fibrosis, how should the nurse respond? Cystic fibrosis is caused by an _____ gene ✔️Answer: Autosomal
recessive
How are potassium and sodium transported across plasma membranes? ✔️Answer: By adenosine triphosphate enzyme (ATPase)
The nurse would be correct in identifying the predominant extracellular cation as: ✔️Answer: Sodium
The early dilation (swelling) of the cell's endoplasmic reticulum results in: ✔️Answer: Reduced protein synthesis
What principle should the nurse remember when trying to distinguish aging from diseases? ✔️Answer: It is difficult to tell the difference
because both processes are believed to result from cell injury.
What is the diagnosis of a 13-year-old female who has a karyotype that reveals an absent homologous X chromosome with only a single X
chromosome present? Her features include a short stature, widely spaced nipples, reduced carrying angle at the elbow, and sparse body hair.
✔️Answer: Turner syndrome
A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information be contained? ✔️Answer:
Nucleolus
The nurse is teaching staff about the most common cause of Down syndrome. What is the nurse describing? ✔️Answer: Maternal
nondisjunction
A 50-year-old male was recently diagnosed with Huntington disease. Transmission of this disease is associated with: ✔️Answer: Delayed age of
onset
A patient wants to know the risk factors for Down syndrome. What is the nurse's best response? ✔️Answer: Pregnancy in women over age 35
What is the role of cytokines in cell reproduction? ✔️Answer: Provide growth factor for tissue growth and development
A newborn male is diagnosed with albinism based on skin, eye, and hair appearance. Which finding will support this diagnosis? ✔️Answer:
Inability to convert tyrosine to DOPA (3,4 dihydroxyphenylalanine)
Sodium and water accumulation in an injured cell are a direct result of: ✔️Answer: Decreased ATP production
A nurse is reading a chart and sees the term oncotic pressure. The nurse recalls that oncotic pressure (colloid osmotic pressure) is determined
by: ✔️Answer: Plasma proteins
The ion transporter that moves Na + and Ca 2+ simultaneously in the same direction is an example of which of the following types of transport?
✔️Answer: Symport
