Correct Answer: D

Rationale: Rationale: 1. Indispensable amino acids, also known as essential amino acids, must be obtained through the diet as the body cannot synthesize them. 2. Amino acids are the building blocks of proteins, so mentioning "indispensable amino acids" indicates understanding of essential dietary proteins. 3. Triglycerides are fats, not proteins, and not related to essential amino acids. 4. Dispensable amino acids can be synthesized by the body, so mentioning them would not indicate understanding of essential proteins.

Correct Answer: A

Rationale: The correct answer is A because floaters are commonly caused by age-related changes in the vitreous humor of the eye, such as the formation of tiny fibers or clumps. These floaters are typically harmless and not a cause for concern. Choice B is incorrect because glasses do not affect floaters in the eye. Choice C is incorrect because floaters are not a primary symptom of glaucoma. Choice D is incorrect because weakened ciliary muscles are not typically associated with floaters. Therefore, the most appropriate interpretation is that seeing floaters is a normal aging process of the eye.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests (LFTs). Yellow skin can indicate jaundice, a sign of liver dysfunction, often seen in patients with liver issues or chemotherapy-related liver toxicity. LFTs including bilirubin, ALT, AST, and ALP can help assess liver function. B: Complete blood count (CBC) and C: Platelet count are not directly related to yellow skin and would not provide information on liver function. D: Blood urea nitrogen and creatinine are tests for kidney function, not liver function. While kidney dysfunction can sometimes cause yellow skin, LFTs are more specific for assessing liver function in this context.

Correct Answer: B

Rationale: The correct answer is B: Asian Americans. Asian Americans have a higher incidence of liver cancer compared to other population groups due to factors such as chronic hepatitis B infection and dietary aflatoxin exposure. Monitoring this group closely is essential for early detection and intervention. Incorrect choices: A: Hispanic - While Hispanics have a higher prevalence of fatty liver disease, the highest risk of liver cancer is not among this group. C: Non-Hispanic Caucasians - Caucasians have a lower incidence of liver cancer compared to Asian Americans. D: Non-Hispanic African-Americans - African-Americans have a lower risk of liver cancer compared to Asian Americans due to differences in risk factors and prevalence of hepatitis B.

Correct Answer: B

Rationale: The correct answer is B: Ensuring that the patient receives adequate palliative care. Palliative care focuses on improving the quality of life for patients with serious illnesses, including managing symptoms and providing emotional support. In this case, since the patient is not receiving treatment for her brain metastases, palliative care would be most appropriate to help alleviate any pain or discomfort she may be experiencing and provide holistic support for her and her family. A: Promoting the patient's functional status and ADLs may not be the priority if the patient's prognosis is terminal and she is not receiving treatment for her brain metastases. C: Ensuring that the family does not tell the patient her condition is terminal goes against ethical principles of honesty and transparency in healthcare. D: Promoting adherence to the prescribed medication regimen may not be relevant if the patient is not receiving active treatment for her brain metastases.
