What tasks can be delegated to his nursing assistant during his tour of duty.

Correct Answer: A

Rationale: A nursing assistant can be delegated the task of changing wound dressings because it is considered a basic nursing care activity that does not require specialized training or knowledge. Nursing assistants are trained to perform tasks related to personal care, hygiene, and basic wound care under the supervision of a registered nurse. Changing wound dressings is a routine nursing task that can be safely delegated to a nursing assistant, allowing the nurse to focus on other aspects of patient care that require specialized nursing skills and knowledge.

Correct Answer: B

Rationale: Acetaminophen (Tylenol) is given pre-operatively to decrease intra-operative anesthetic requirements and post-operative pain. It is a common analgesic that can help reduce the amount of intra-operative anesthesia needed and provide some pain relief during the surgery. Unlike drugs like Celebrex, Ibuprofen, and Demerol, Acetaminophen does not have anti-inflammatory properties, but it is effective in managing pain and can contribute to overall pain control before, during, and after surgery. This makes it a preferred choice for pre-operative medication in order to decrease the need for higher doses of anesthetics and reduce post-operative pain levels.

Correct Answer: B

Rationale: The extraneous variable in a study is a variable that is not the main focus of the study but could potentially impact the results. In this case, the length of stay is an extraneous variable because it is not directly related to the research question or objective of the study. The study is likely focused on factors such as patient age, complications, or date of admission, making the length of stay an irrelevant variable in this context.

Correct Answer: B

Rationale: Ella's statement "I will hang myself" directly indicates a desire and intent to commit suicide. This is classified as a suicidal intent, which is a serious concern that requires immediate attention and intervention. It is crucial to take any mention or indication of suicide seriously and seek help from mental health professionals or crisis intervention services.

Correct Answer: D

Rationale: Alzheimer's disease is the most common form of dementia. Dementia is a general term for a decline in mental ability that becomes severe enough to interfere with daily life. It can affect memory, thinking skills, and the ability to perform everyday tasks. Alzheimer's disease specifically is a progressive brain disorder that slowly destroys memory and thinking skills and eventually impairs the ability to carry out simple tasks. Therefore, the provided condition of having difficulty in processing stimuli and new information aligns with the symptoms commonly seen in individuals with Alzheimer's disease.
