Correct Answer: D

Rationale: Informed consent is a critical ethical requirement in research involving human participants. In this study scenario, it is crucial that both the participants and their parents provide consent. The involvement of the parents is important, especially when the participants are minors or vulnerable individuals who may not fully understand the study's implications or risks. By obtaining consent from both the participants and their parents, researchers can ensure that everyone involved is aware of what participation in the study entails, including any potential risks or benefits. This approach upholds the principles of autonomy, respect for individuals, and ethical research conduct.

Correct Answer: A

Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.

Correct Answer: B

Rationale: In the grading system used for edema, +1 indicates no visible edema in the leg, +2 indicates slight edema with indentations that quickly resolve, +3 indicates moderate edema with deeper indentations that may take longer to resolve, and +4 indicates severe edema with very swollen legs. In this case, since the edema is described as slightly swollen, the appropriate grade to document would be +2.

Correct Answer: C

Rationale: RA 9173, also known as the Philippine Nursing Act of 2002, is the law that declares the State policy to promote and upgrade the practice of the nursing profession in the Philippines. This law provides for the regulation and maintenance of high standards of nursing education and practice in the country. It aims to ensure the welfare and professional growth of Filipino nurses and to safeguard the health of the public by maintaining competency and professionalism in the nursing profession. Therefore, RA 9173 is the correct choice that reflects the State's policy to promote and upgrade the practice of the nursing profession in the Philippines.

Correct Answer: A

Rationale: The patient's presentation with a blood sugar level of 800mg/dL, absence of ketones in the urine, dehydration, and altered mental status points towards Hyperosmolar nonketotic coma (HNKC). HNKC typically occurs in patients with Type 2 diabetes and is characterized by extremely high blood glucose levels (hyperglycemia) without significant ketosis. The absence of ketones in the urine distinguishes HNKC from Diabetic ketoacidosis (DKA). Patients with HNKC often present with severe dehydration, altered mental status, and hyperosmolarity. It is crucial to address the underlying cause of the hyperglycemia, correct dehydration, and normalize blood glucose levels promptly in the management of HNKC.
