A charge nurse is teaching a newly licensed nurse about health care-associated infections (HAIs). Which of the following should the nurse include in the teaching as examples of HAIS?

A. Proper oral hygiene is crucial for preventing ventilator-associated pneumonia (VAP), which is a common complication in ventilated patients. The bundle often includes instructions on how to perform mouth care to reduce the risk of bacterial colonization in the oral cavity and subsequent aspiration into the lungs.
B. Tracheostomy care, including suctioning as needed, is important to maintain airway patency and prevent complications like mucus plugging. However, specific instructions for suctioning frequency (e.g., every 2 hours) may vary based on the patient's clinical condition and the presence of secretions. It is not universally part of the ventilator care bundle but is an essential component of managing patients with tracheostomies.
C. Correct ventilator settings are critical to support adequate oxygenation and ventilation while minimizing lung injury. Nurses should be knowledgeable about how to monitor and adjust ventilator settings based on the patient's respiratory status. Education on ventilator settings may be included in

training related to mechanical ventilation management, but it is not typically part of a standardized ventilator care bundle.
D. The position of the patient can affect ventilation and respiratory mechanics. In the context of ventilator care, positioning recommendations may include elevating the head of the bed (semi-Fowler's position) to reduce the risk of aspiration and improve lung expansion. Placing the client in a supine position alone is not specific to the ventilator care bundle but may be considered based on the patient's clinical condition.

A. Tachycardia refers to a rapid heart rate, typically defined as a heart rate greater than 100 beats per minute. Theophylline can stimulate the heart and central nervous system, leading to an increase in heart rate. Tachycardia is a known adverse effect of theophylline and can occur especially if the medication is taken in higher doses or if there are interactions with other medications or caffeine.
B. Constipation is not a common adverse effect of theophylline. Theophylline primarily affects the respiratory and cardiovascular systems rather than the gastrointestinal system. Therefore, constipation is unlikely to be caused by theophylline therapy.
C. Drowsiness is generally not a common adverse effect of theophylline. Instead, theophylline is more likely to cause CNS stimulation, which can lead to insomnia, restlessness, or anxiety rather than drowsiness.
D. Oliguria refers to decreased urine output, which is not typically associated with theophylline use. Theophylline primarily affects respiratory function and cardiovascular parameters. Decreased urine output can occur in certain conditions or with medications that affect kidney function, but it is not a recognized adverse effect of theophylline.
