Question 2.2. A 77-year-old male patient with a diagnosis of stomach cancer has been found to have metastases in his liver. The patient and his family are surprised at this turn of events, stating that they don’t see how he could have developed cancer in his liver. Which of the following facts would underlie the reply that the care team provides? (Points : 3)

The parenchymal tissue of the liver is particularly susceptible to secondary malignancies.

The portal circulatory system brings venous blood from the gastrointestinal tract into the liver.

Hepatic stromal tissue shares characteristics with cancerous cells, including lack of anchorage dependence.

The proximity of the liver to the stomach allows for direct spread of cancerous cells due to a lack of contact inhibition.

Question 3.3. The NP is teaching a group of older adults about the value of including foods containing antioxidants in their diet. Which of the following statements best captures the rationale underlying the NPs advice?(Points : 3)

Antioxidants inhibit the actions of reactive oxygen species (ROS).

Antioxidants react nonspecifically with molecules.

Antioxidants prevent the occurrence of cell dysplasia.

Question 4.4. The nurse practitioner is providing care for a patient with a diagnosis of cirrhosis, and he notes that the patient’s sclerae are jaundiced. The nurse practitioner recalls that jaundice is caused by excess accumulation of bilirubin, a pigment that can accumulate in which part of the cell? (Points : 3)

Nucleus

Cytoplasm

Golgi apparatus

Rough endoplasmic reticulum (ER)

“She is living with an example of an autosomal recessive disorder.”

“The patient is likely to be photosensitive as a result of the disease.”

Question 7.7. A child possesses a trait that is the result of the interaction of two different genes, neither of which could have produced the trait independently. Which of the following explanations best captures the genetic explanation for this?(Points : 3)

The trait is an expression of multiple alleles.

Epistasis has dictated the phenotypic outcome.

The phenomenon is an example of polygenic inheritance.

The outcome is the result of the interaction between collaborative genes.

Question 8.8. Which of the following statements most accurately conveys an aspect of cell injury due to impaired calcium homeostasis? (Points : 3)

Normal intracellular calcium ion levels are higher than extracellular levels.

Ischemia and certain toxins cause a decrease in cytosolic calcium.

Injured cells tend to accumulate calcium.

Low calcium levels cause an activation of damaging enzymes.

Question 9.9. A group of researchers has identified that the prevalence of two particular genetic disorders share a statistical correlation. Which of the following statements best conveys the genetic rationale for this situation? (Points : 3)

There is likely a cause-and-effect relationship between the two genes responsible.
