A client with chronic lower back pain has been taking ibuprofen PO twice a day for several months. Which assessment is most important for the nurse to complete?

A. Ask about the client's bedtime routine: While understanding the client's bedtime routine can be helpful in assessing sleep difficulties, it may not directly address the impact of the medication on sleep. Knowing the bedtime routine alone does not specifically identify how the medication timing affects sleep.
B. Inquire about perceived anxiety: Anxiety can contribute to sleep difficulties, but the primary concern in this scenario is the potential impact of the medication on sleep. The timing of the medication is more directly related to sleep problems.
C. Determine what time the dose is taken: This is the most important assessment. Dextroamphetamine-amphetamine extended-release tablets can cause insomnia or disrupt sleep if taken too late in the day due to their stimulating effects. Identifying the time the dose is taken helps determine if adjusting the timing could alleviate sleep difficulties.
D. Determine daily caffeine intake: While caffeine intake can affect sleep, the primary concern in this case is the effect of the stimulant medication on sleep patterns. Knowing the timing of the medication is more directly relevant to understanding and managing sleep issues.

A) When using the discus, have the client breathe out rapidly into the mouthpiece: This instruction is incorrect because the client should not breathe out into the discus mouthpiece. Exhaling into the device could result in moisture entering the discus, which may cause the medication powder to clump, reducing the dose received and potentially making the device unusable.
B) Offer the discus to the client for use during an acute asthma attack: This is not appropriate because fluticasone and salmeterol discus is not a rescue inhaler. It is a long-acting bronchodilator and corticosteroid combination meant for maintenance therapy, not for quick relief during an acute asthma attack. Short-acting bronchodilators like albuterol are used for immediate relief.
C) Clients using the discus may experience decreased blood pressure: There is no known association between the use of the fluticasone/salmeterol discus and decreased blood pressure. The primary side effects associated with this medication include potential respiratory effects, such as throat irritation, and not systemic cardiovascular effects like low blood pressure.
D) Explain that the client should not use the discus more than twice daily: This is the correct instruction because the fluticasone/salmeterol combination is designed for maintenance therapy and should not be used more than twice daily. Overuse can increase the risk of side effects, such as oral thrush, hoarseness, or more serious systemic effects from the corticosteroid and long-acting beta-agonist components.
