Rationale: Used wet diapers and gloves should be disposed of in a black waste bin. Black waste bins are designated for general waste, which includes non-infectious materials that do not pose a risk of infection to others. Wet diapers and gloves fall under this category as they are considered non-infectious waste. Proper disposal in the black bin helps in maintaining cleanliness and hygiene in the healthcare setting.

Correct Answer: C

Rationale: Qualitative research design focuses on gaining an in-depth understanding of attitudes, beliefs, motivations, and behaviors of individuals or groups. It does not typically involve statistical analysis or estimation of relationships between variables like quantitative designs do. Qualitative research involves collecting data through methods such as interviews, observations, or focus groups to provide rich and detailed insights into the experiences and perspectives of the participants. The emphasis is on understanding the meanings individuals attach to their experiences, rather than generalizing findings to a larger population.

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

Correct Answer: A

Rationale: Total knee arthroplasty (TKA), also known as total knee replacement, is a surgical procedure commonly performed to alleviate symptoms and improve function in patients with advanced osteoarthritis of the knee that has not responded to conservative management. During TKA, the damaged cartilage and bone in the knee joint are removed and replaced with prosthetic components. This procedure aims to reduce pain, restore function, and improve the quality of life for individuals with severe osteoarthritis of the knee. High tibial osteotomy (HTO) is typically performed in younger patients with unicompartmental osteoarthritis, while knee arthroscopy and meniscectomy are more targeted towards specific knee conditions and may not provide significant relief in cases of advanced osteoarthritis.

Correct Answer: A

Rationale: The nurse sharing Mr. Steve's medical records with a group of visiting members of a medical mission team violates his right to expect that all communications and records pertaining to his care should be treated as confidential. Patient confidentiality is a fundamental ethical principle in healthcare that protects a patient's privacy and sensitive information. Sharing medical records without the patient's consent breaches this confidentiality and can lead to legal and ethical consequences. It is important for healthcare providers to maintain the confidentiality of patient information to uphold trust between patients and healthcare professionals.
