Correct Answer: C

Rationale: The correct answer is C: Assist to a standing position. This action helps utilize gravity to aid in emptying the bladder and may help the patient void without the need for invasive measures like catheterization or medications. It is a non-invasive and natural approach to promote urination. Limiting fluid intake (A) could worsen the situation by concentrating urine and worsening retention. Inserting a urinary catheter (B) should be considered only if other measures fail. Asking for a diuretic medication (D) does not address the immediate need for bladder emptying and may not be necessary if the patient can void naturally.

Correct Answer: B

Rationale: The correct answer is B: Focusing the patient's immune system exclusively on the tumor. Biologic response modifiers (BRMs) work by enhancing the body's natural defenses to target and attack cancer cells specifically. This approach helps the immune system to recognize and destroy cancer cells while minimizing harm to normal cells. A: Promoting the synthesis and release of leukocytes - This is not the primary mechanism of action for BRMs. While leukocytes play a role in the immune response, BRMs target the immune system's response to tumors. C: Potentiating the effects of chemotherapeutic agents and radiation therapy - While some BRMs may be used in combination with these treatments, their primary mode of action is not to enhance the effects of chemotherapy or radiation therapy. D: Altering the immunologic relationship between the tumor and the patient - This choice is too broad and vague. BRMs specifically aim to direct the immune response towards targeting the tumor cells, rather than altering the overall immunologic relationship

Correct Answer: D

Rationale: The correct answer is D because saturated fats are primarily found in animal sources such as red meat, poultry, and dairy products. It is important to limit the intake of saturated fats on a low-fat diet to reduce the risk of heart disease and other health issues. A: Polyunsaturated fats are actually considered healthy fats and should not be restricted to less than 7% of total calories. B: Transfat is a type of unhealthy fat that should be avoided altogether, not just limited to 7% of total calories. C: Unsaturated fats are actually found mostly in plant-based sources like nuts, seeds, and avocados, not animal sources. In summary, choice D is correct because it provides accurate information about the source of saturated fats in animal products, while the other choices provide incorrect or misleading information about different types of fats.

Correct Answer: A

Rationale: The correct answer is A: Type I hypersensitivity reaction. This type of reaction involves the release of histamine from mast cells and basophils, leading to symptoms like hives. It is characterized by the involvement of IgE antibodies. In this case, the patient developed hives quickly after exposure to the allergen, indicating an immediate hypersensitivity reaction typical of Type I. Choices B, C, and D are incorrect because they are associated with different mechanisms and timeframes of hypersensitivity reactions. Type II involves antibody-mediated cell destruction, Type III involves immune complex deposition, and Type IV is a delayed-type hypersensitivity reaction mediated by T cells, none of which are consistent with the rapid onset of hives seen in this patient.

Correct Answer: B

Rationale: The correct answer is B: Increased abdominal girth. In ovarian cancer, a common clinical manifestation is the accumulation of fluid in the abdomen, leading to increased abdominal girth. This is known as ascites. The presence of ascites can be observed through physical examination and abdominal imaging. A: Fish-like vaginal odor is not typically associated with ovarian cancer. It may be a symptom of other gynecological conditions. C: Fever and chills are not specific to ovarian cancer and can be seen in various infectious or inflammatory conditions. D: Lower abdominal pelvic pain is a common symptom in many gynecological conditions but is not a specific manifestation of ovarian cancer.
