The nurse is caring for a client who had an appendectomy 4 hours ago. Which finding requires immediate action by the nurse?

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.

Choice A reason: Gastroccult positive emesis indicates the presence of blood in the vomit, which is a sign of a serious complication such as anastomotic leak, ulcer, or bleeding. The nurse should notify the physician and monitor the client's vital signs and hemoglobin level.

Choice B reason: Strong foul smelling flatus is a common side effect of BPD, which involves bypassing a large portion of the small intestine and creating a connection between the stomach and the colon. This results in malabsorption and bacterial overgrowth, which produce gas and odor.

Choice C reason: Complaint of poor night vision is a sign of vitamin A deficiency, which can occur after BPD due to reduced absorption of fat-soluble vitamins. The nurse should advise the client to take vitamin supplements and eat foods rich in vitamin A, such as carrots, sweet potatoes, and spinach.

Choice D reason: Loose bowel movements are another common side effect of BPD, which causes diarrhea and steatorrhea (fatty stools). The nurse should encourage the client to drink fluids with electrolytes and avoid foods that worsen diarrhea, such as greasy, spicy, or sugary foods.
