The nurse teaches a patient how to live with a new tracheostomy. Which of the ff. instructions is appropriate?

Correct Answer: C

Rationale: Option C, "Be sure to protect your tracheostomy from pollutants such as powders, hair and chemicals," is the most appropriate instruction for a patient with a new tracheostomy. It is important to keep the tracheostomy site clean and free from any potential irritants or contaminants that could cause infection or complications. Powders, hair, and chemicals can lead to irritation or clogging of the tracheostomy tube, so it is crucial for the patient to be mindful of avoiding such pollutants near the tracheostomy site.

Correct Answer: C

Rationale: A positive Homans' sign indicates possible deep vein thrombosis (DVT) in the leg. When a patient has DVT, the clot may dislodge and travel to the lungs, causing a pulmonary embolism, which can be life-threatening. Therefore, ambulation and performing the Homans' sign can dislodge the clot and potentially cause an embolism. It is contraindicated to prevent this serious complication.

Correct Answer: C

Rationale: IgM is the first immunoglobulin produced during an acute infection. It is the first class of antibodies secreted by B cells in response to an antigenic challenge. IgM antibodies are produced initially in primary immune responses and play a crucial role in activating the complement system. IgG is produced after IgM and is the most abundant immunoglobulin in the secondary immune response. IgE is responsible for allergic reactions, and IgD's function is not fully understood but is believed to be involved in the activation of B cells.

Correct Answer: C

Rationale: Driving in the car with the windows open is not a recommended action for someone with allergies to pollen. Keeping the windows closed while driving can help minimize exposure to pollen particles in the air. By driving with the windows open, the individual is increasing their exposure to pollen and not effectively controlling their allergy symptoms. Staying indoors on dry, windy days (Choice A), refusing to walk outside in the spring (Choice B), and working in the garden on sunny days (Choice D) are all actions that demonstrate understanding of how to control allergies to pollen by avoiding potential triggers.

Correct Answer: A

Rationale: People with AIDS often experience weight loss and malnutrition due to the disease's impact on the immune system. A high-protein, high-calorie diet can help support the immune system and maintain or improve weight. Dividing the meals into six servings can help with better absorption of nutrients and provide a steady source of energy throughout the day. This type of diet can also help manage symptoms and side effects of the disease and its treatments, such as maintaining muscle mass, managing nausea, and supporting overall health.
