A patient with a new diagnosis of lung cancer decides to have radiation therapy. Which of the ff. expectations of this treatment is most appropriate?
- A. Complete cure of the cancer
- B. Prevention of the need for oxygen
- C. Increased comfort
- D. Prevention of cancer spread
Correct Answer: C
Rationale: Radiation therapy for lung cancer is typically used with the goal of increasing comfort for the patient by reducing symptoms such as pain, shortness of breath, and coughing. While it may help to shrink tumors and slow the progression of the disease, it is usually not considered a curative treatment for advanced lung cancer. It is important for the patient to have realistic expectations and understand that the goal of radiation therapy is primarily to improve their quality of life and manage symptoms.
A 10-mo-old boy has a left suprarenal mass. Surgery is accomplished with complete removal of the mass as well as the non-adherent lymph nodes; surgical biopsies are taken during surgery. The histology reveals poorly differentiated neuroblastoma with microscopic ipsilateral lymph nodes involvement. The contralateral lymph nodes are negative. Of the following, the BEST therapeutic approach for this infant is
- A. chemotherapy
- B. radiotherapy
- C. concomitant chemo-radiotherapy
- D. chemotherapy followed by radiotherapy
Correct Answer: A
Rationale: Complete resection with microscopic residual disease typically warrants adjuvant chemotherapy.
You are assigned to evaluate the outcome of fecal occult blood test as a screening test for patients with bowel cancer. The total number of patients who underwent the test is 2030; in those whom the disease is confirmed are 30. The results of fecal occult blood test are as follows: in 20 patients who has a confirmed bowel cancer (truly positive), and in 180 patients who don't have the disease (falsely positive); in 10 patients who truly has the disease (falsely negative), and in 1820 patients who are not affected by the disease (truly negative). All the following statements are true EXCEPT
- A. the prevalence of the disease for those population is 1.48%
- B. the sensitivity of the test is 67%
- C. the specificity of the test is 91%
- D. the positive predictive value is 20%
Correct Answer: A
Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
Which would be best for the nurse to use when determining the temperature of a preterm infant under a radiant heater?
- A. Axillary sensor TestBankWorld.org
- B. Tympanic membrane sensor
- C. Rectal mercury glass thermometer
- D. Rectal electronic thermometer
Correct Answer: B
Rationale: A tympanic membrane sensor or tympanic thermometer is the best option for determining the temperature of a preterm infant under a radiant heater. Tympanic thermometers are quick and non-invasive, making them ideal for use in neonatal care. They provide accurate readings by measuring the infrared heat waves coming from the eardrum. This method is preferred over other options like axillary sensors, rectal mercury thermometers, and rectal electronic thermometers, which may not be as efficient or suitable for use with preterm infants.
