A nurse is teaching a client about self-administering a subcutaneous injection to the abdomen. Which of the following instructions should the nurse include?

Choice A rationale:

Performing oral care once each day is not sufficient to reduce the risk of ventilator-associated pneumonia (VAP). Ventilated patients are at an increased risk of developing VAP due to the presence of an endotracheal tube that bypasses the body's natural defenses. Bacteria can accumulate in the mouth and respiratory tract, leading to pneumonia. Therefore, performing oral care only once a day is inadequate for maintaining oral hygiene and preventing VAP.

Choice B rationale:

Brushing the client's teeth with a firm-bristle toothbrush can cause trauma to the oral tissues, potentially leading to bleeding and irritation. In critically ill patients with an endotracheal tube, using a firm-bristle toothbrush can exacerbate the risk of infection and VAP. It is essential to use gentle and non-traumatic methods for oral care to maintain the integrity of the oral mucosa.

Choice C rationale:

Swabbing the client's mouth with chlorhexidine solution is the correct choice. Chlorhexidine is an antiseptic solution that effectively reduces the growth of bacteria in the oral cavity. Regular use of chlorhexidine mouthwash has been shown to decrease the risk of VAP in mechanically ventilated patients. By reducing the bacterial load in the mouth, the risk of aspiration and subsequent pneumonia is lowered, making it a crucial intervention for preventing VAP.

Choice D rationale:

Raising the head of the bed by 15° for oral care is an important measure to prevent aspiration during oral care. However, it alone is not sufficient to reduce the risk of VAP. While proper head positioning helps prevent the entry of oral secretions into the lower respiratory tract, it must be combined with effective oral hygiene practices, such as using chlorhexidine solution, to comprehensively reduce the risk of VAP.

Choice A rationale:

1 cup of shredded lettuce is low in potassium and is not the best source of potassium for a client with heart failure. While vegetables like lettuce are generally healthy, they do not provide a significant amount of potassium.

Choice B rationale:

1 cup of cantaloupe is the best source of potassium among the given options. Cantaloupe is a fruit that contains a moderate amount of potassium. Including this fruit in the client's diet can help maintain a balanced potassium level, which is important for heart health.

Choice C rationale:

1 oz of tuna is a source of protein but is not particularly rich in potassium. While protein intake is important for overall health, other choices on the list provide more potassium, which is specifically needed for clients with heart failure.

Choice D rationale:

1 cup of raspberries is a good source of fiber and antioxidants, but it is not as rich in potassium as cantaloupe. While raspberries can be a healthy addition to the diet, they are not the best choice for addressing potassium needs in this scenario.
