Prior to a thoracentesis, which of the following actions should the nurse take?

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: 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: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.

Correct Answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.

Correct Answer: B

Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.

Correct Answer: B

Rationale: In a client with left homonymous hemianopsia, there is a loss of vision on the right side of both eyes. Placing the bedside table on the right side of the bed ensures that essential items are within the client's field of vision, minimizing the risk of injury or accidents. Teaching the client to scan to the right and orienting them using the clock method may be helpful strategies, but placing the bedside table on the right side of the bed is a more direct and immediate intervention to enhance the client's safety and independence.

Correct Answer: C

Rationale: Administering potassium via IV bolus is a high-risk procedure that requires careful attention and adherence to established protocols to prevent serious complications like cardiac arrest. Errors in administering IV medications, especially potent ones like potassium, can lead to severe harm to the patient and potential legal consequences for the healthcare provider. Therefore, including this example in the in-service on malpractice issues helps emphasize the importance of safe medication administration practices and the potential implications of errors.

Correct Answer: D

Rationale: Assessing breath sounds every 1 to 2 hours is crucial in monitoring the client's respiratory status and identifying any potential complications promptly. Monitoring ventilator settings every 8 hours is important for overall ventilation management. Documenting the endotracheal tube placement accurately is essential to ensure proper positioning. Using a vest restraint if self-extubation is attempted is not a recommended intervention as it can lead to complications and should be avoided.

Correct Answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.
