A client is using the nasal spray hormone calcitonin to reduce bone loss from osteoporosis. To reduce rhinitis associated with administration of the nasal spray, the nurse should provide the client with which instruction?

A. Alternate the use of each nostril when administering the nasal spray each day: Alternating nostrils can help reduce local irritation and rhinitis associated with the use of nasal spray medications. This practice allows each nostril to recover and reduces the risk of continuous irritation from the spray. B. Do not lie down within thirty minutes of use of the nasal spray: While this can help ensure the medication is absorbed properly, it is not specifically aimed at reducing rhinitis. It is more important to manage irritation by alternating nostrils. C. Use a nonsteroidal anti-inflammatory drug (NSAID) PRN to reduce any inflammation that may occur: NSAIDs might not be suitable for everyone, and using them could mask symptoms or lead to additional side effects. They are not a primary strategy for managing rhinitis caused by nasal spray use. D. Take an over-the-counter antihistamine with each daily dose of nasal spray: Antihistamines are not typically used to manage rhinitis caused by nasal sprays. Additionally, combining medications should be done cautiously and usually under medical advice.
