A client is hospitalized with an inflammatory bowel disease (IBD) exacerbation and is being treated with a corticosteroid. The client develops a rigid abdomen with rebound tenderness. Which action should the nurse take?

Choice A reason: This is incorrect because reviewing the need for pneumococcal vaccine is not the most important intervention for the nurse to implement. Pneumococcal vaccine is recommended for people who are at high risk of pneumococcal infections, such as those with chronic diseases or immunosuppression. However, it is not a priority action for a client with neutropenia, which is a low number of neutrophils that increases the risk of bacterial and fungal infections.

Choice B reason: This is incorrect because implementing bleeding precautions is not the most important intervention for the nurse to implement. Bleeding precautions are indicated for clients who have thrombocytopenia, which is a low number of platelets that impairs blood clotting. However, this is not the case for a client with neutropenia, which affects the white blood cells that fight infections.

Choice C reason: This is incorrect because assessing vital signs every 4 hours is not the most important intervention for the nurse to implement. Vital signs are important indicators of the client's health status and may reveal signs of infection, such as fever, tachycardia, or hypotension. However, this is not a sufficient measure to prevent or treat infections in a client with neutropenia, who needs more aggressive and proactive interventions.

Choice D reason: This is correct because placing the client in protective isolation is the most important intervention for the nurse to implement. Protective isolation, also known as reverse isolation or neutropenic precautions, is a set of measures that aim to protect the client from exposure to pathogens that may cause infections. These include wearing gloves, masks, gowns, and eye protection; using sterile equipment and techniques; avoiding contact with people who are sick or have infections; and restricting visitors and fresh flowers or fruits.

Choice A reason: This is incorrect because monitoring pulse oximetry every 2 hours is not a sufficient or timely intervention for the nurse to implement. Pulse oximetry is a noninvasive method of measuring the oxygen saturation of hemoglobin in the blood. Normal oxygen saturation is 95% to 100%, while hypoxemia is less than 90%. However, pulse oximetry may not reflect the severity of respiratory distress or the effectiveness of nebulizer treatment in a client with asthma. Moreover, monitoring pulse oximetry every 2 hours is too infrequent for a client who is in acute respiratory distress and needs more frequent assessment and intervention.

Choice B reason: This is incorrect because teaching proper use of a rescue inhaler is not a priority or relevant intervention for the nurse to implement. A rescue inhaler is a type of short-acting bronchodilator that can be used to relieve acute asthma symptoms by relaxing the smooth muscles of the airways and improving airflow. However, teaching proper use of a rescue inhaler is not an urgent action for a client who is already receiving nebulizer treatment, which delivers a higher dose of medication directly to the lungs. Moreover, teaching proper use of a rescue inhaler is not appropriate for a client who is in respiratory distress and may not be able to focus or retain information.

Choice C reason: This is correct because elevating the head of bed to 90 degrees is the most important intervention for the nurse to implement. Elevating the head of bed to 90 degrees can help improve breathing and oxygenation by reducing pressure on the diaphragm and chest wall, increasing lung expansion and ventilation, and facilitating expectoration of mucus. This can enhance the effects of nebulizer treatment and reduce respiratory distress in a client with asthma.

Choice D reason: This is incorrect because determining exposure to asthmatic triggers is not an immediate or helpful intervention for the nurse to implement. Asthmatic triggers are substances or factors that can cause or worsen asthma symptoms by inducing inflammation or constriction of the airways. Examples of asthmatic triggers include allergens, irritants, infections, exercise, stress, or weather changes. However, determining exposure to asthmatic triggers is not a priority action for a client who is in respiratory distress and needs more urgent interventions to improve breathing and oxygenation. Moreover, determining exposure to asthmatic triggers may not change the management or outcome of an acute asthma attack that has already occurred.
