The nurse recognizes that one primary difference between normal and cancer cells is related to regulated cell death that normal cells undergo as part of the regular cell cycle. What is the term for this change in cellular function?

Contact inhibition

Anaplasia

Apoptosis

Anchorage dependence

Answer and Explanation

The Correct Answer is C

A. Contact inhibition refers to the process where normal cells stop growing when they come into contact with other cells. Cancer cells often lose this ability and continue to proliferate despite contact.
B. Anaplasia refers to the loss of differentiation in cancer cells, making them look less like the normal cells from which they originated. This is not directly related to regulated cell death.
C. Apoptosis is the term for programmed cell death, a normal process where cells that are damaged or no longer needed die in a controlled manner. Cancer cells often evade apoptosis, allowing them to survive and proliferate uncontrollably.
D. Anchorage dependence refers to the need for cells to be anchored to a surface to divide. Cancer cells often lose anchorage dependence, allowing them to grow independently.

B. Being bitten by a tick or other insect refers to vector-borne transmission, not contact transmission.
C. Ingesting food containing a disease-carrying organism refers to foodborne transmission, not contact transmission.
D. Contact transmission occurs when a person comes into direct physical contact with a pathogen, such as through skin-to-skin contact, touching contaminated surfaces, or exposure to bodily fluids.

A. Have a clinical breast examination every 3 years. B. Have a mammogram every 5 years. C. Have an annual clinical breast examination. D. Have a mammogram every 3 years.

Correct Answer is C

Explanation

A. Clinical breast examination (CBE) should be done annually for women at higher risk, not every 3 years.
B. Mammograms are generally recommended every year starting at age 40 for women at average risk. For those with a strong family history of breast cancer, earlier and more frequent screening may be advised.
C. An annual clinical breast examination (CBE) is recommended for women, especially those with a higher risk of breast cancer, such as a family history. This allows healthcare providers to check for any abnormalities in the breasts.
D. Mammograms every 3 years are generally not sufficient for women at higher risk; they should start annual mammograms at age 40, or possibly earlier based on family history or genetic factors.
