Which statement is incorrect regarding an informed consent signed by a patient?

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.

Correct Answer: A

Rationale: The correct answer is A because it correctly matches the terms with their definitions. Topical anesthesia is indeed applied directly to the skin and mucous membranes, matching with statement C. Epidural anesthesia involves injecting the anesthesia into the epidural space of the spinal cord, aligning with statement D. The other choices incorrectly match the terms with definitions that do not correspond to the actual procedures. Choice B incorrectly states that epidural anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5, which is not accurate. Choice C incorrectly states that topical anesthesia is applied directly to the skin and mucous membranes, which is inaccurate. Choice D incorrectly states that topical anesthesia is applied directly to the skin and that epidural anesthesia is introduced in the subarachnoid space, both of which are incorrect.

Correct Answer: D

Rationale: I'm sorry, but the correct answer provided (D: Aorta) is actually incorrect in this context. The major veins commonly used in parenteral cannulation are A: Basilic vein, B: Femoral vein, and C: Subclavian vein. The aorta is a major artery, not a vein, and is not typically used for parenteral cannulation due to its high pressure and risk of complications. It's important to understand the differences between veins and arteries when considering cannulation sites.

Correct Answer: D

Rationale: The correct answer is D: Acute respiratory failure. Tracheostomy is indicated in cases of severe respiratory compromise when the upper airway is obstructed or when long-term mechanical ventilation is needed. It ensures a patent airway and facilitates weaning from a ventilator. Choices A, B, and C are incorrect as drainage of pleural effusion, hemorrhage, and infections do not typically require a tracheostomy for management.

Correct Answer: A

Rationale: Rationale: 1. Bone marrow puncture is not indicated for analgesia but for diagnostic purposes. 2. Antibiotics may be indicated to prevent infection during the procedure. 3. Anaesthesia may be used to minimize pain and discomfort. 4. Inflammation is a condition that may necessitate bone marrow puncture for diagnosis. Therefore, choice A is the correct answer as it does not align with the therapeutic indications of bone marrow puncture.
