Parkinson's disease is associated with the loss of which of the following neurotransmitter?

Correct Answer: C

Rationale: The correct answer is C: Dopamine. Parkinson's disease is primarily caused by the loss of dopamine-producing neurons in the brain. Dopamine is crucial for controlling movement, mood, and cognition. Serotonin (A) is not directly related to Parkinson's. Adrenaline (B) is involved in the fight-or-flight response, not Parkinson's. GABA (D) is an inhibitory neurotransmitter, not typically associated with Parkinson's disease.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): I. Epilepsy can have a genetic predisposition, as certain genetic factors can increase the likelihood of developing epilepsy, making statement I true (T). II. Old age is indeed a risk factor for Parkinson's disease, as the incidence of the disease increases with age, making statement II true (T). Therefore, the correct answer is A (TT). Summary of Incorrect Choices: B: FT - This choice is incorrect because both statements I and II are true. C: TF - This choice is incorrect because statement I is true (T) and statement II is also true (T). D: FF - This choice is incorrect because both statements I and II are true.

Correct Answer: A

Rationale: The correct answer is A: Apply warm blankets & continue oxygen as prescribed. Shivering after surgery indicates the patient is cold due to anesthesia effects. Applying warm blankets helps raise body temperature, reducing shivering. Oxygen is crucial post-surgery. Taking rectal temperature or adjusting room temperature is not the priority. Paging the doctor should only be done if the patient's condition worsens.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Conducting the Time Out is typically part of the surgical safety checklist during the actual surgery, not the preoperative checklist. 2. Assessing for allergies is important to prevent adverse reactions during surgery. 3. Ensuring informed consent is signed is crucial for legal and ethical reasons. 4. Ensuring history and physical examination are completed helps in assessing the patient's health status before surgery. Therefore, choice B is not typically part of the preoperative checklist, making it the correct answer.

Correct Answer: A

Rationale: The correct answer is A because it is incorrect to state that the nurse is responsible for obtaining the consent for surgery. Informed consent for surgery is typically obtained by the physician performing the procedure, not the nurse. Nurses can assist in the process by providing information and clarifying details, but ultimately it is the physician's responsibility to ensure the patient understands the procedure and consents to it. Choice B is correct as minors under 18 years of age generally require a parent or legal guardian to sign a consent form on their behalf. Choice C is correct as nurses can witness the client signing the consent form as a part of the process. Choice D is also correct as it is indeed the nurse's responsibility to ensure the patient has been educated by the physician before obtaining informed consent.
