1. Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:
- A. the client's hemoglobin and hematocrit are normal.
- B. red blood cells are affected first.
- C. folic acid levels are normal.
- D. the current white cell count is not affected by chemotherapy.
Correct answer: D
Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy. Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.
2. Which factor in a client’s health history increases their risk for cancer?
- A. Family history and environment
- B. Alcohol and smoking
- C. Alcohol consumption and smoking
- D. Proximity to an electric plant and water source
Correct answer: B
Rationale: The correct answer is 'Alcohol and smoking.' Both alcohol consumption and smoking are well-known risk factors for various types of cancer. They have a synergistic effect, meaning their combined impact raises the risk significantly. Family history and environment (Choice A) may play a role in certain cancers, but alcohol and smoking are more directly linked to increased cancer risk. Proximity to an electric plant and water source (Choice D) is not typically associated with an increased risk of cancer compared to alcohol and smoking.
3. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?
- A. Aspirin
- B. Diazoxide
- C. Procardia
- D. Mannitol
Correct answer: C
Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.
4. Which of the following can certain foods like broccoli, oranges, dark greens, and dark yellow vegetables help improve?
- A. Vitamin intake
- B. Body functions
- C. Defense mechanisms
- D. Disease cure
Correct answer: C
Rationale: Certain foods like broccoli, oranges, dark greens, and dark yellow vegetables can help improve defense mechanisms by enhancing the immune system and overall health. While these foods can boost defense mechanisms, they are not a cure for diseases, do not balance body functions, and are not intended to solely supplement vitamin intake, which may be necessary in some cases. Therefore, the correct answer is defense mechanisms as these foods strengthen the body's ability to fight off illnesses and maintain health.
5. A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is underway and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?
- A. Administer O2 if necessary.
- B. Turn the client on her left side.
- C. Notify the physician.
- D. No action is necessary.
Correct answer: D
Rationale: The correct answer is 'No action is necessary.' In this scenario, the fetal heart deceleration of uniform shape observed is an early deceleration resulting from head compression. Early decelerations are benign and typically do not require any intervention as they mirror the contraction pattern. It is essential to closely observe both the mother and the baby. Administering O2 (Choice A) is not necessary as early decelerations do not indicate fetal distress. Turning the client on her left side (Choice B) is not required for early decelerations. Notifying the physician (Choice C) is not needed for this type of deceleration, as it is a normal response to head compression during labor.
