The nurse is preparing a client with breast cancer for BRCA1 and BRCA2 genetic testing. Which pathophysiological process should the nurse use to support client teaching?
The choice of treatment is best determined by the sensitivity of these genetic markers.
BRCA1 and BRCA2 provide protection of mature, functioning breast and ovarian cells.
Mutations in BRCA1 or BRCA2 identify a client’s risk for cancerous cell development in breast tissue.
The prognosis of breast cancer is most successful when these markers are inherited mutations.
The Correct Answer is C
Choice A rationale
While the sensitivity of genetic markers can influence the choice of treatment, it is not the primary pathophysiological process involved in BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify genetic mutations that increase the risk of developing certain types of cancer.
Choice B rationale
BRCA1 and BRCA2 do play a role in protecting mature, functioning breast and ovarian cells. However, this is not the primary reason for conducting BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify mutations that increase cancer risk.
Choice C rationale
This is the correct answer. Mutations in BRCA1 or BRCA2 can significantly increase a person’s risk for developing breast and ovarian cancer. Therefore, identifying these mutations through genetic testing can help determine a person’s cancer risk.
Choice D rationale
While inherited mutations in BRCA1 and BRCA2 can influence the prognosis of breast cancer, the primary purpose of BRCA1 and BRCA2 genetic testing is to identify mutations that increase cancer risk, not to determine prognosis.

Correct Answer is D
Explanation
Choice A rationale
While it’s true that phantom limb pain can be a normal post-surgical sensation, simply reassuring the patient doesn’t address the pain they’re experiencing.
Choice B rationale
Guiding in moving the unaffected limb to override the sensation being experienced is not a recommended intervention for phantom limb pain. Phantom limb pain is a complex phenomenon that is not simply overridden by movement of other body parts.
Choice C rationale
Explaining that the sensations of tingling and pain are not real may invalidate the patient’s experience. Phantom limb pain is a real phenomenon experienced by many amputees. It’s not just a sensation; it’s a type of neuropathic pain that can be severe and debilitating.
Choice D rationale
Affirming that a prosthetic with physical therapy will gradually improve the symptoms is the best non-pharmacological intervention among the choices. Physical therapy, including mirror therapy and other desensitization techniques, can help manage phantom limb pain. The use of a prosthetic can help the patient regain function and mobility, which can also improve their overall well-being and potentially reduce the perception of phantom limb pain.
Correct Answer is A
Explanation
Choice A rationale
Histamine H2-receptor antagonists, also known as H2 blockers, are medications that help reduce the production of gastric acid. They achieve this by blocking H2 receptors in the parietal cells of the stomach, which are responsible for secreting hydrochloric acid (HCl)12. This reduction in acid secretion can help treat conditions such as peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome, which are all conditions that can be exacerbated by excessive stomach acid.
Choice B rationale
While H2 blockers do help manage the symptoms of peptic ulcer disease, they do not directly destroy the microorganisms causing inflammation in the stomach. The primary cause of peptic ulcers is a bacterium called Helicobacter pylori, and the treatment for an H. pylori infection typically involves a combination of antibiotics and proton pump inhibitors, not H2 blockers.
Choice C rationale
H2 blockers do not neutralize hydrochloric acid (HCl) in the stomach. Instead, they work by reducing the amount of acid produced by the stomach. Antacids, not H2 blockers, are the class of drugs that work by neutralizing stomach acid.
Choice D rationale
H2 blockers do not inhibit the action of acetylcholine by blocking parasympathetic nerve endings. Anticholinergic medications are the ones that work by blocking the action of acetylcholine, a neurotransmitter that transmits signals in the nervous system.
