Rationale: Attending a lecture-demonstration on doing first aid is essential for the growth of a student nurse as it equips them with crucial knowledge and skills to respond effectively in emergency situations. First aid training teaches basic life-saving techniques and how to provide immediate care until medical professionals arrive. This knowledge is vital in the healthcare field, allowing the student nurse to provide immediate assistance and potentially save lives. By learning first aid procedures, the student nurse can enhance their skills, confidence, and overall capability to care for patients in various settings. This continuous learning and improvement are key to personal growth and professional development in the healthcare industry.

Correct Answer: A

Rationale: Transient ischemic attack (TIA) is a temporary episode of neurological dysfunction caused by a temporary disruption in blood supply to the brain. The symptoms of a TIA typically last for a short period of time, usually less than 1 hour. In some cases, the symptoms may last up to 24 hours but generally resolve within a shorter time frame. It is important for healthcare providers to recognize the symptoms of a TIA promptly and assess the patient for appropriate management to prevent the risk of a full-blown stroke.

Correct Answer: B

Rationale: When managing a conscious patient with a severe nosebleed (epistaxis), the appropriate intervention is to have the patient sit upright and lean slightly forward to prevent blood from flowing into the throat and causing choking or swallowing. Pinching the soft part of the nose just below the bony part can help apply pressure to the bleeding vessel and stop the bleeding. This maneuver also helps compress the blood vessels in the nose, promoting clot formation and stopping the bleeding. It is important not to tilt the head back as this can cause blood to flow into the throat and potentially lead to swallowing, choking, or aspiration. Packing the nose with cotton gauze should be done by medical professionals if the bleeding does not stop with direct pressure. Applying direct pressure to the forehead is not effective for managing nosebleeds; pressure should be applied to the nostrils instead.

Correct Answer: A

Rationale: The patient's lack of sensation in her right leg, allowing her cat to scratch her without her noticing, is indicative of neuropathy. Neuropathy is a common diabetic complication characterized by nerve damage that can result in loss of sensation or altered sensation in different parts of the body, including the extremities. In this case, neuropathy has likely affected the patient's right lower extremity, leading to her inability to feel the cat scratching her leg and resulting in the unnoticed scratches, infection, and subsequent cellulitis.

Correct Answer: D
