The nurse is caring for a client on a ventilator from complications of pneumonia. The nurse observes the low-pressure ventilator alarm and a pulse oximetry reading of 85%. What should be the nurse's first action?

Assisting the patient to get out of bed is a task that can be safely delegated to UAP, as long as the patient's mobility and transfer status allow for assistance without the need for specialized nursing skills. UAPs are trained to provide basic patient care, including assisting with activities of daily living, under the supervision and direction of licensed healthcare professionals.

Teaching the patient to purse lip breath requires knowledge and understanding of the technique, as well as the ability to assess the patient's response and provide feedback. This is best done by a licensed healthcare professional, such as a nurse or respiratory therapist. Auscultating breath sounds every 4 hours requires the ability to correctly use a stethoscope and interpret the findings. This task falls within the scope of practice of a nurse or respiratory therapist who has received appropriate training.

Planning patient activities to minimize exertion requires knowledge of the patient's condition, limitations, and goals. It involves assessment, evaluation, and coordination of care, which are typically performed by licensed healthcare professionals.

Mrs. Kalen is diagnosed with gastroenteritis and dehydration, and the arterial blood gas results indicate metabolic alkalosis (elevated pH and HCO3-). This suggests that there is an excessive loss of gastric acid and chloride ions from vomiting, leading to an imbalance of electrolytes and an increase in bicarbonate levels.

To correct the imbalance and treat dehydration, the primary intervention is fluid replacement. Administration of IV 0.9 Saline Solution, also known as normal saline, is commonly used for fluid resuscitation and rehydration. This isotonic solution helps restore fluid balance and electrolyte levels in the body.

Administration of antiemetics may help control vomiting, but the primary treatment focus in this case is fluid and electrolyte replacement to correct dehydration and the associated metabolic alkalosis.

Administration of diuretics, which increase urine output, would not be appropriate in this case as the patient is already experiencing dehydration.

Electrolyte replacement may be necessary if there are specific electrolyte imbalances identified, but the primary treatment is fluid replacement with IV saline solution.

Having the patient go home and rest without addressing the underlying dehydration and metabolic alkalosis would not be appropriate as it can lead to further complications.
