ATI Oncology Questions
1. The cells of a normal individual can replicate in a specified rate. If the rate of replication becomes uncontrollable, which of the following is lacking from the patient?
- A. Apoptosis
- B. Contact inhibition
- C. Stable cells
- D. Labile cells
Correct answer: B
Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.
2. A 35-year-old male is admitted to the hospital complaining of severe headaches, vomiting, and testicular pain. His blood work shows reduced numbers of platelets, leukocytes, and erythrocytes, with a high proportion of immature cells. The nurse caring for this patient suspects a diagnosis of what?
- A. AML
- B. CML
- C. MDS
- D. ALL
Correct answer: D
Rationale: Acute Lymphocytic Leukemia (ALL) is a type of cancer where immature lymphocytes (a type of white blood cell) proliferate uncontrollably in the bone marrow. This leads to a reduction in the production of platelets, leukocytes, and erythrocytes, causing symptoms such as fatigue, anemia, bleeding tendencies, and increased susceptibility to infection. In ALL, leukemic cell infiltration into other organs is common, which can manifest as severe headaches (due to central nervous system involvement), vomiting, and testicular pain (due to infiltration of leukemic cells into the testes). These are hallmark signs of ALL, especially in younger patients.
3. Mina, who is suspected of an ovarian tumor is scheduled for a pelvic ultrasound. The nurse provides which preprocedure instruction to the client?
- A. Eat a light breakfast only
- B. Maintain an NPO status before the procedure
- C. Wear comfortable clothing and shoes for the procedure
- D. Drink six to eight glasses of water without voiding before the test
Correct answer: D
Rationale: A pelvic ultrasound requires the client to have a full bladder because the bladder acts as a window through which pelvic organs, such as the uterus and ovaries, can be visualized more clearly. The full bladder pushes the intestines out of the way and provides a better acoustic pathway for the ultrasound waves. Without this, the pelvic organs might be obscured, and the images would be less accurate.
4. A patient who is undergoing consolidation therapy for the treatment of leukemia has been experiencing debilitating fatigue. How can the nurse best meet this patients needs for physical activity?
- A. Teach the patient about the risks of immobility and the benefits of exercise.
- B. Assist the patient to a chair during awake times, as tolerated.
- C. Collaborate with the physical therapist to arrange for stair exercises.
- D. Teach the patient to perform deep breathing and coughing exercises.
Correct answer: B
Rationale: For patients undergoing consolidation therapy for leukemia, severe fatigue is a common side effect of treatment due to factors such as anemia, decreased nutritional intake, and the body’s response to chemotherapy. While exercise is beneficial, the patient's fatigue may limit their ability to engage in strenuous activity. Assisting the patient to sit in a chair during awake times is a practical way to encourage some physical activity while respecting their fatigue levels. This intervention helps prevent complications associated with immobility, such as muscle atrophy and venous stasis, without overwhelming the patient. It allows the patient to engage in light activity that is manageable and promotes recovery.
5. The nurse is caring for a client who is at risk for tumor lysis syndrome. Which laboratory value requires the nurse to intervene?
- A. Decreased blood urea nitrogen (BUN)
- B. Increased serum calcium
- C. Increased creatinine level
- D. Increased blood glucose level
Correct answer: C
Rationale: Tumor lysis syndrome (TLS) is a potentially life-threatening condition that occurs when large numbers of cancer cells die rapidly, releasing their contents into the bloodstream. This can overwhelm the kidneys and lead to acute kidney injury. Creatinine is a waste product filtered out of the blood by the kidneys, and an elevated creatinine level is a sign of kidney dysfunction or damage. In TLS, increased creatinine levels indicate that the kidneys are struggling to filter out the excess waste products from cell breakdown, requiring immediate intervention to prevent further complications, such as acute renal failure.
