A nurse is assessing a client who reports a nevus that has increased in size and an irregularly shaped lesion that varies in color. These findings are consistent with which of the following medical diagnoses?
Squamous cell carcinoma
Malignant melanoma
Kaposi's sarcoma
Basal cell carcinoma
The Correct Answer is B
Choice A reason:
Squamous cell carcinoma typically presents as a rough, scaly, red patch, open sore, or raised growth with a central depression, often on sun-exposed areas of the body. While it can appear as a lesion that varies in color, it is not commonly associated with a nevus that has increased in size.
Choice B reason:
Malignant melanoma is associated with changes in preexisting nevi, such as an increase in size and variations in color. It often appears as a mole that changes in color, size, or feel and may have irregular edges. The description of the lesion provided by the client is characteristic of malignant melanoma, making this the correct diagnosis.
Choice C reason:
Kaposi's sarcoma is a cancer that forms in the lining of blood and lymph vessels and typically appears as patches of abnormal tissue on the skin or mucous membranes. These lesions are usually red or purple and look similar to bruises¹. They are not typically described as nevi that increase in size or lesions that vary in color.
Choice D reason:
Basal cell carcinoma often appears as a slightly transparent bump on the skin, though it can take other forms. It usually presents as a pearly white or pink bump on white skin, or a brown or black bump on darker skin, and is most often found on sun-exposed areas. It is not typically associated with a nevus that has increased in size or an irregularly shaped lesion that varies in color.

Correct Answer is C
Explanation
Choice A reason:
Mucositis is an inflammation of the mucous membranes lining the digestive tract, which is commonly associated with chemotherapy and radiation therapy, not directly with opioid use. While it can be a concern for cancer patients, it is not a typical side effect of opioids.
Choice B reason:
Bleeding is not a common side effect of opioid medications. While cancer patients may experience bleeding due to various reasons, including the cancer itself or treatment-related issues, opioids do not typically cause bleeding.
Choice C reason:
Opioid-induced constipation (OIC) is a common side effect of opioid medications due to their action on the gastrointestinal tract. Opioids reduce gastrointestinal motility, leading to constipation, which can progress to impaction if not managed properly. This is a manifestation that nurses should anticipate and manage proactively in clients taking opioid medications for pain management.
Choice D reason:
Diarrhea is not typically associated with opioid use. In fact, opioids are more likely to cause constipation rather than diarrhea. Diarrhea may occur as a result of other treatments or conditions but is not a direct side effect of opioids.
Correct Answer is B
Explanation
Choice A reason:
This choice suggests a pH of 7.50, which is indicative of alkalosis, and not typically expected in a client with chronic kidney disease (CKD). CKD often leads to metabolic acidosis due to the accumulation of acids in the body as the kidneys fail to excrete them. The HCO₃⁻ level of 20 mEq/L is slightly lower than the normal range (22-26 mEq/L), and the PaCO₂ of 32 mm Hg is within the normal range (35-45 mm Hg), but these values do not align with the expected acidosis associated with CKD.
Choice B reason:
This set of values is consistent with metabolic acidosis, which is commonly seen in clients with CKD. A pH of 7.25 indicates acidemia, and an HCO₃⁻ level of 19 mEq/L is below the normal range, suggesting a primary metabolic acidosis. The PaCO₂ of 30 mm Hg is at the lower end of the normal range, which may indicate a compensatory respiratory response to the metabolic acidosis.
Choice C reason:
A pH of 7.30, while on the lower side, is not as acidic as one would expect in a client with CKD. The HCO₃⁻ level of 26 mEq/L is within the normal range, and a PaCO₂ of 50 mm Hg suggests respiratory acidosis, which is not the primary disorder in CKD.
Choice D reason:
This choice indicates a pH of 7.55, which is too alkaline and not characteristic of CKD, where metabolic acidosis is the expected finding. An HCO₃⁻ level of 30 mEq/L is higher than the normal range, suggesting metabolic alkalosis. The PaCO₂ of 31 mm Hg is slightly below the normal range, possibly indicating a compensatory response, but it does not align with the metabolic acidosis typically seen in CKD.
