A client with acute renal injury (AKI) weighs 110.3 pounds (50 kg) and has a potassium level of 6.7 mEq/L (6.7 mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]

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: Jogging or running are not excellent aerobic exercises for an older adult client with osteoarthritis. These activities can put a lot of stress and impact on the joints, especially the knees, hips, and ankles, which can worsen the pain and inflammation of osteoarthritis. The nurse should advise the client to avoid high-impact exercises that can damage the cartilage and bones.

Choice B reason: Tennis or racquetball are not ideal exercises for an older adult client with osteoarthritis. These activities involve sudden movements, twists, and turns that can strain the joints, especially the elbows, wrists, and shoulders, which can aggravate the symptoms of osteoarthritis. The nurse should advise the client to avoid exercises that can cause joint instability and injury.

Choice C reason: Limiting the exercise to just the daily activities is not a good advice for an older adult client with osteoarthritis. Exercise is important for maintaining joint health, mobility, and function, as well as preventing muscle loss, obesity, and cardiovascular diseases. The nurse should encourage the client to engage in regular moderate exercise that can improve the quality of life and reduce the complications of osteoarthritis.

Choice D reason: Swimming is an excellent exercise for an older adult client with osteoarthritis. Swimming is a low-impact aerobic exercise that can strengthen the muscles, improve the cardiovascular fitness, and enhance the flexibility of the joints without putting too much pressure or stress on them. Swimming can also reduce the pain and stiffness of osteoarthritis by providing a soothing and relaxing effect on the body. The nurse should recommend swimming as a safe and effective exercise for the client.
