An oncology nurse educator is providing health education to a patient who has been diagnosed with skin cancer. The patients wife has asked about the differences between normal cells and cancer cells. What characteristic of a cancer cell should the educator cite?
- A. Malignant cells contain more fibronectin than normal body cells.
- B. Malignant cells contain proteins called tumor-specific antigens.
- C. Chromosomes contained in cancer cells are more durable and stable than those of normal cells.
- D. The nuclei of cancer cells are unusually large, but regularly shaped.
Correct Answer: B
Rationale: The correct answer is B: Malignant cells contain proteins called tumor-specific antigens. Tumor-specific antigens are unique to cancer cells and are not found in normal cells. This characteristic distinguishes cancer cells from normal cells and is important in cancer detection and treatment.
A: Malignant cells do not necessarily contain more fibronectin than normal body cells. Fibronectin is a glycoprotein found in the extracellular matrix and is not a defining characteristic of cancer cells.
C: Chromosomes in cancer cells are actually more prone to instability and mutations compared to normal cells, making them less durable and stable.
D: The nuclei of cancer cells can vary in size and shape, with irregularities often seen, rather than being unusually large and regularly shaped.

Examination of a newborn in the birth room reveals bilateral cataracts. Which disease process in the maternal history would likely cause this abnormality?
- A. Rubella
- B. Cytomegalovirus (CMV)
- C. Syphilis
- D. HIV
Correct Answer: A
Rationale: The correct answer is A: Rubella. Rubella infection during pregnancy can lead to congenital rubella syndrome, which includes bilateral cataracts as a characteristic feature. Rubella virus can cross the placenta and affect the developing fetus. Cytomegalovirus (CMV) can also cause congenital cataracts, but rubella is more commonly associated with this abnormality. Syphilis can cause other congenital abnormalities but not bilateral cataracts. HIV does not typically lead to bilateral cataracts in newborns.
An oncology nurse is caring for a patient who has developed erythema following radiation therapy. What should the nurse instruct the patient to do?
- A. Periodically apply ice to the area.
- B. Keep the area cleanly shaven.
- C. Apply petroleum jelly to the affected area.
- D. Avoid using soap on the treatment area.
Correct Answer: C
Rationale: The correct answer is C: Apply petroleum jelly to the affected area. This is because petroleum jelly helps to soothe and protect the skin, reducing dryness and irritation caused by radiation therapy. Ice (A) can further damage the skin, shaving (B) can increase the risk of infection, and soap (D) can be too harsh on the sensitive skin. Therefore, instructing the patient to apply petroleum jelly is the most appropriate recommendation to promote skin healing and comfort.
The nurse is providing discharge education to an adult patient who will begin a regimen of ocular medications for the treatment of glaucoma. How can the nurse best determine if the patient is able to self-administer these medications safely and effectively?
- A. Assess the patient for any previous inability to self-manage medications.
- B. Ask the patient to demonstrate the instillation of her medications.
- C. Determine whether the patient can accurately describe the appropriate method of administering her medications.
- D. Assess the patients functional status.
Correct Answer: B
Rationale: The correct answer is B. By asking the patient to demonstrate the instillation of medications, the nurse can directly assess the patient's ability to self-administer the medications safely and effectively. This method allows for a practical demonstration of skills, which is more reliable than relying solely on verbal descriptions or past experiences. Choices A, C, and D are incorrect because assessing for previous inability, describing the method, or evaluating functional status may not directly demonstrate the patient's competency in self-administering ocular medications.
A nurse is teaching patients about health care information. Which patient will the nurse assess closely for health literacy?
- A. A patient 35 years old
- B. A patient 68 years old
- C. A patient with a college degree
- D. A patient with a high-school diploma
Correct Answer: D
Rationale: The correct answer is D because patients with lower health literacy, such as those with a high-school diploma, may struggle to understand complex health information. The nurse should assess this patient closely to ensure they comprehend and can follow instructions. Patients with higher education levels (college degree) may have better health literacy skills. Age alone (35 or 68 years old) does not determine health literacy level. It is essential to focus on the patient's educational background to assess their health literacy effectively.
A nurse in a long-term care setting that is fundedby Medicare and Medicaid is completing standardized protocols for assessment and care planning for reimbursement. Which task is the nurse completing?
- A. A minimum data set
- B. An admission assessment and acuity level
- C. A focused assessment/specific body system
- D. An intake assessment form and auditing phase
Correct Answer: A
Rationale: The correct answer is A: A minimum data set. In a long-term care setting funded by Medicare and Medicaid, completing standardized protocols for assessment and care planning for reimbursement involves using a minimum data set, which is a standardized instrument for assessing residents' health status. This set of data elements is necessary for comprehensive assessment and care planning to ensure appropriate reimbursement. The other choices (B, C, D) do not specifically address the standardized protocols required for reimbursement in this setting. An admission assessment and acuity level would be part of the process, but not the primary task being completed in this scenario. A focused assessment on a specific body system or an intake assessment form and auditing phase are not synonymous with the standardized protocols needed for reimbursement in a Medicare/Medicaid-funded long-term care facility.
