Correct Answer: C

Rationale: The correct answer is C: Surgical removal. Surgical removal of the cancerous tumor is the best treatment before metastasis because it physically removes the cancer cells. Chemotherapy and radiation are used to treat cancer after it has spread, not as the primary treatment. Choice D is incorrect because not all types of cancer can be effectively treated with all three options.

Correct Answer: D

Rationale: The correct answer is D: An aminoglycoside. Aminoglycosides, such as gentamicin or amikacin, can interact with cisplatin by increasing the risk of nephrotoxicity and ototoxicity. Both cisplatin and aminoglycosides have the potential to cause kidney damage, and when used together, the risk of kidney toxicity is significantly increased. This interaction is due to the additive effects on the kidneys. Therefore, it is crucial to monitor renal function closely and adjust the dosages of these drugs accordingly to prevent severe adverse effects. Summary: A: Erythromycin - Erythromycin is not known to have significant interactions with cisplatin. B: A cephalosporin - Cephalosporins do not typically interact with cisplatin in a clinically significant manner. C: A tetracycline - Tetracyclines are not known to cause significant interactions with

Correct Answer: B

Rationale: The correct answer is B: IgE. IgE is specific to allergic responses as it binds to mast cells and basophils, triggering the release of histamine and other inflammatory mediators. IgA is more involved in mucosal immunity, IgG is involved in long-term immunity and opsonization, and IgM is the primary antibody in the primary immune response. IgB is not a known immunoglobulin. Therefore, IgE is the specific immunoglobulin associated with allergic responses due to its role in mediating hypersensitivity reactions.

Correct Answer: B

Rationale: The correct answer is B because conducting the interview in a quiet environment, like the waiting area with the television turned off, reduces background noise and distractions for the patient with a hearing deficit. This allows for better communication and understanding. A: Conducting the interview in the patient's room with the door closed may still have distractions or noise from outside the room. C: Conducting the interview in the patient's room before administration of pain medication does not address the issue of reducing background noise for better communication. D: Conducting the interview in the waiting room while the occupational therapist is working on leg exercises introduces additional distractions and noise, making it harder for the patient with a hearing deficit to communicate effectively.

Correct Answer: C

Rationale: The correct answer is C. Driving in the car with the windows open exposes the patient to pollen, worsening allergies. Staying indoors on dry, windy days (A) reduces exposure. Refusing to walk outside in spring (B) also minimizes exposure. Working in the garden on sunny days (D) increases pollen exposure. Therefore, choice C is the only action that goes against controlling pollen allergies.
