Myelosuppression is one of the most common effects of chemotherapy. How would the nurse assess for this condition?
Monitor the CXR results.
Monitor the BMP, especially the sodium, potassium, and magnesium counts.
Monitor the CBC, especially the neutrophil, platelet, and RBC counts.
Monitor the spinal fluid analysis.
The Correct Answer is C
Choice A Reason:
Monitoring the CXR (chest X-ray) results is not directly related to assessing myelosuppression. A chest X-ray is typically used to evaluate the lungs and heart, and while it can help identify infections or other complications, it does not provide information about bone marrow activity or blood cell counts. Myelosuppression specifically affects the production of blood cells in the bone marrow, which is best assessed through blood tests like the CBC (Complete Blood Count).
Choice B Reason:
Monitoring the BMP (Basic Metabolic Panel), especially the sodium, potassium, and magnesium counts, is important for evaluating electrolyte balance and kidney function. However, it does not directly assess myelosuppression. Myelosuppression involves the suppression of bone marrow activity, leading to decreased production of blood cells, which is not reflected in electrolyte levels.
Choice C Reason:
Monitoring the CBC (Complete Blood Count), especially the neutrophil, platelet, and RBC (red blood cell) counts, is the most appropriate method for assessing myelosuppression. Myelosuppression results in decreased production of blood cells, including neutrophils (a type of white blood cell), platelets, and red blood cells. A CBC provides detailed information about these cell counts and helps identify conditions like neutropenia (low neutrophil count), thrombocytopenia (low platelet count), and anemia (low red blood cell count), which are common consequences of myelosuppression.
Choice D Reason:
Monitoring the spinal fluid analysis is not relevant for assessing myelosuppression. Spinal fluid analysis is typically used to diagnose conditions affecting the central nervous system, such as infections, bleeding, or multiple sclerosis. It does not provide information about bone marrow activity or blood cell counts, which are the primary concerns in myelosuppression.

Correct Answer is C
Explanation
Choice A: Alkalosis
Alkalosis occurs when the blood pH is higher than the normal range, specifically above 7.45. This condition indicates that the blood is too alkaline. Causes of alkalosis can include hyperventilation, loss of stomach acid through vomiting, or an overuse of diuretics. Since a blood pH of 7.21 is below the normal range, it does not indicate alkalosis.
Choice B: Normal Blood pH
The normal pH range for blood is between 7.35 and 7.45. This range is crucial for the body’s metabolic processes and enzyme functions. A blood pH of 7.21 is below this range, indicating an abnormal condition.
Choice C: Acidosis
Acidosis is the correct answer. It occurs when the blood pH drops below 7.35, indicating that the blood is too acidic. A pH of 7.21 is significantly below the normal range, confirming acidosis. This condition can result from various factors, including respiratory issues that lead to an accumulation of carbon dioxide or metabolic problems that increase acid production or decrease bicarbonate levels.
Choice D: Hyperkalemia
Hyperkalemia refers to an elevated level of potassium in the blood, not a change in blood pH. While hyperkalemia can be associated with acidosis, it is not defined by the pH level itself. Therefore, a blood pH of 7.21 does not directly indicate hyperkalemia.
Correct Answer is False
Explanation
Choice A: True
The statement that all patient teaching occurs in a formalized teaching session is not accurate. While formalized teaching sessions are an important aspect of patient education, they are not the only method used. Formal sessions are structured and planned, often involving detailed explanations, demonstrations, and the use of educational materials. These sessions are beneficial for covering complex topics and ensuring that patients and caregivers have a thorough understanding of their health conditions and treatment plans.
Choice B: False
Patient teaching can occur in various settings and formats, not just in formalized teaching sessions. Informal teaching moments are equally important and often occur during routine interactions between healthcare providers and patients. These moments can include brief explanations, answering questions, and providing reassurance during procedures or daily care activities. Informal teaching is flexible and can be tailored to the patient’s immediate needs and readiness to learn, making it a crucial component of effective patient education.
