ATI Fundamentals

Correct Answer: A

Rationale: An SaO2 of 95% indicates an improvement in the client's oxygen saturation, suggesting better respiratory status. In asthma exacerbation, a decrease in SaO2 levels would signal worsening respiratory distress. Wheezing, retraction of sternal muscles, and premature ventricular complexes are indicators of respiratory compromise and worsening respiratory status in acute asthma attacks. Monitoring SaO2 levels is crucial in assessing the effectiveness of interventions and guiding treatment decisions.

Correct Answer: A

Rationale: Positioning the client in an upright position, leaning over the bedside table helps to facilitate access to the thoracic cavity during the thoracentesis procedure. This position allows for easier identification and access to the insertion site. Explaining the procedure to the client is important, but positioning is the priority. Obtaining ABGs is not directly related to the thoracentesis procedure. Administering benzocaine spray is not a standard practice before a thoracentesis.

Correct Answer: B

Rationale: When assessing a client with a history of asthma, the nurse should identify environmental allergies as a risk factor for asthma. Environmental allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms and exacerbate the condition. Gender, alcohol consumption, and other factors may not directly contribute to the development or exacerbation of asthma.

Correct Answer: B

Rationale: When a chest tube is accidentally removed, the priority action for the nurse is to immediately seal the insertion site with a gloved hand, a sterile occlusive dressing, or petroleum gauze to prevent air from entering the pleural space and causing a pneumothorax. Applying sterile gauze to the insertion site is not the correct initial action. The first step is to prevent respiratory compromise by ensuring the site is sealed. Therefore, the nurse should not apply sterile gauze to the insertion site first.
