A nurse measures a client's weight as 70 kg and height as 1.1 m. What is the client's body mass index? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Using liquids to clear food from the client's mouth is not a safe intervention for dysphagia. Liquids can easily enter the airway and cause aspiration, which is the inhalation of food or fluids into the lungs. Aspiration can lead to pneumonia, respiratory distress, and death.

Choice B reason: Tilting the client's head backwards to facilitate swallowing is not a safe intervention for dysphagia. This position can also increase the risk of aspiration, as it opens the airway and allows food or fluids to flow into it.

Choice C reason: Adding a thickening agent to liquids is a safe and effective intervention for dysphagia. Thickened liquids are easier to swallow and control, as they move more slowly through the mouth and throat. They also reduce the risk of aspiration, as they are less likely to enter the airway.

Choice D reason: Placing the client in a semi-Fowler's position is not a safe intervention for dysphagia. This position can also increase the risk of aspiration, as it lowers the head and neck and reduces the closure of the airway. A better position for dysphagia is upright or high-Fowler's, which elevates the head and neck and enhances the closure of the airway.

Choice A reason: Tilt your head forward while you eat is a correct instruction for dysphagia. This position can help prevent choking by closing the airway and directing food and fluids to the back of the mouth and throat.

Choice B reason: Obtain your vitamins in liquid form is not a correct instruction for dysphagia. Liquid vitamins can be too thin and watery for people with dysphagia, as they can easily enter the airway and cause aspiration. Vitamins should be taken in pill or chewable form, or crushed and mixed with thickened liquids or pureed foods.

Choice C reason: Cool foods down to room temperature before consuming is not a correct instruction for dysphagia. Food temperature does not affect the risk of choking for people with dysphagia, as long as the food is not too hot or too cold. Food texture and consistency are more important factors for safe swallowing.

Choice D reason: Drink water with each bite of food is not a correct instruction for dysphagia. Water can also be too thin and watery for people with dysphagia, as it can also enter the airway and cause aspiration. Water should be thickened to a nectar-like, honey-like, or pudding-like consistency, depending on the individual's needs and preferences.
