patient is experiencing bone marrow depression as a result of chemotherapy. Which assessment should the nurse expect because of this health problem?

platelet count of 50.000

nausea and vomiting

temperature of 38.9 C (102F)

alopecia

Answer and Explanation

The Correct Answer is C

A. Platelet count of 50,000 is low (normal is usually 150,000-450,000), and this can be associated with bone marrow depression caused by chemotherapy. However, bone marrow depression itself doesn't cause a fever directly. The low platelet count increases the risk of bleeding, but it wouldn't necessarily lead to a temperature elevation by itself.

B. Nausea and vomiting are common side effects of chemotherapy but are not directly related to bone marrow depression. Bone marrow depression typically affects the production of blood cells (red blood cells, white blood cells, and platelets), but nausea and vomiting are more directly associated with the chemotherapy agents themselves rather than the resulting bone marrow suppression.

C. A fever of 38.9°C (102°F) could indicate an infection, which is a serious risk for patients with bone marrow depression due to chemotherapy. The suppression of white blood cell (WBC) production from chemotherapy leads to neutropenia, leaving the patient more vulnerable to infections. A fever in this context is a medical emergency and requires immediate attention, as it may signify a bacterial or fungal infection, which could be life-threatening in an immunocompromised patient.

D. Alopecia (hair loss) is a well-known side effect of chemotherapy, but it is not a direct consequence of bone marrow depression. It is more related to the chemotherapy drugs affecting rapidly dividing cells, like those in hair follicles. While it is a common and distressing symptom, it is not an indicator of bone marrow function or depression.

Correct Answer is B

Explanation

A. While age is a risk factor for colorectal cancer, the risk typically increases after age 50, not at 35. Most colorectal cancers are diagnosed in individuals over the age of 50, so age over 50 is a more significant risk factor.

B. Ulcerative colitis is a chronic inflammatory bowel disease that increases the risk of developing colorectal cancer, especially after long-term inflammation. The risk increases the longer someone has had ulcerative colitis, particularly if the disease affects a large portion of the colon.

C. A high fiber, low fat diet is actually protective against colorectal cancer. Diets rich in fiber and low in fat have been shown to reduce the risk of developing colorectal cancer by promoting bowel regularity and reducing inflammation in the colon.

D. While having a first-degree relative (parent, sibling, or child) with colorectal cancer is a significant risk factor, having a distant relative (e.g., cousin, aunt, uncle) with the disease does not carry the same increased risk. The genetic risk is more strongly associated with immediate family members.

Correct Answer is ["480"]

Explanation

Convert time to hours:
25 minutes ÷ 60 = 0.4167 hours

Step 2:
Use the formula:
Rate (mL/hr) = Volume (mL) ÷ Time (hr)

Rate = 200 mL ÷ 0.4167 hr ≈ 480 mL/hr
