To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?

When using the discus, have the client breathe out rapidly into the mouthpiece.

Offer the discus to the client for use during an acute asthma attack.

Clients using the discus may experience decreased blood pressure.

Explain that the client should not use the discus more than twice daily.

Answer and Explanation

The Correct Answer is D

Choice A reason: This is not a correct instruction for the nurse to provide to the client's caregivers. When using the discus, the client should breathe out slowly and gently away from the mouthpiece, not into it. Breathing out rapidly into the mouthpiece can cause the powder to disperse and reduce the amount of medication delivered to the lungs. The client should also rinse the mouthpiece with water after each use and dry it thoroughly.

Choice B reason: This is not a correct instruction for the nurse to provide to the client's caregivers. The discus is not intended for use during an acute asthma attack, as it does not provide immediate relief of bronchospasm. The discus is a combination of fluticasone, a corticosteroid that reduces inflammation, and salmeterol, a long-acting beta-agonist that relaxes the airway muscles. The discus is a maintenance therapy that should be used regularly to prevent asthma symptoms and exacerbations. The client should also have a rescue inhaler, such as albuterol, for quick relief of asthma attacks.

Choice C reason: This is not a correct instruction for the nurse to provide to the client's caregivers. Clients using the discus may experience increased blood pressure, not decreased, as a possible side effect of salmeterol. Salmeterol can stimulate the beta receptors in the heart and blood vessels, causing tachycardia, palpitations, and hypertension. The nurse should monitor the client's blood pressure and heart rate regularly and report any abnormal findings to the healthcare provider.

Choice D reason: This is the correct instruction for the nurse to provide to the client's caregivers. The discus should not be used more than twice daily, as it can increase the risk of adverse effects and reduce the effectiveness of the medication. The discus should be used once in the morning and once in the evening, about 12 hours apart, to provide optimal control of asthma symptoms. The nurse should teach the client and the caregivers how to use the discus correctly and safely, and to follow the prescribed dosage and schedule.

Correct Answer is C

Explanation

Choice A reason: Confirming that the daughter is aware of the progressive nature of the disease is not the best response, as it does not address the daughter's misconception about the drug. The nurse should educate the daughter that rivastigmine does not cure or stop the progression of Alzheimer's disease, but only slows down the cognitive decline.

Choice B reason: Affirming the decision to use the medication when the symptoms start to worsen is not appropriate, as it contradicts the evidence-based practice. The nurse should inform the daughter that rivastigmine is most effective when used in the early stages of Alzheimer's disease, as it can delay the need for institutionalization and improve the quality of life.

Choice C reason: Explaining that the drug should be used early in the course of the disease process is the best response, as it corrects the daughter's misunderstanding and provides accurate information. The nurse should explain that rivastigmine works by inhibiting the enzyme that breaks down acetylcholine, a neurotransmitter that is involved in memory and learning. By increasing the level of acetylcholine in the brain, rivastigmine can improve the cognitive function and behavior of the client.

Choice D reason: Assessing the client's current mental status before deciding to support the decision is not relevant, as it does not address the daughter's concern or the rationale for the drug. The nurse should already have the client's baseline mental status from the initial assessment and diagnosis. The nurse should focus on educating the daughter about the benefits and risks of rivastigmine and encouraging her to follow the prescribed regimen.

A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure. B. The synergistic effect of the multiple medications has resulted in drug toxicity and hypotension. C. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness. D. The additive effect of multiple medications has caused the blood pressure to drop too low.

Correct Answer is D

Explanation

Choice A reason: Increased urinary clearance of the multiple medications is not the cause of the client's syncope. Diuresis is a common side effect of some antihypertensive medications, such as diuretics, but it does not lower the blood pressure to a dangerous level. The nurse should monitor the client's fluid and electrolyte balance and urine output, but it is not the priority action in this situation.

Choice B reason: The synergistic effect of the multiple medications is not the cause of the client's syncope. Synergism is when two or more drugs work together to produce a greater effect than the sum of their individual effects. This can be beneficial or harmful, depending on the drugs and the doses. The nurse should check the client's medication history and avoid prescribing drugs that have a negative synergistic effect, but it is not the most likely explanation for the client's hypotension.

Choice C reason: The antagonistic interaction among the various blood pressure medications is not the cause of the client's syncope. Antagonism is when two or more drugs work against each other to reduce or cancel out their effects. This can decrease the effectiveness of the treatment and increase the risk of complications. The nurse should check the client's medication history and avoid prescribing drugs that have a negative antagonistic effect, but it is not the most likely explanation for the client's hypotension.

Choice D reason: The additive effect of multiple medications is the most likely cause of the client's syncope. Additivity is when two or more drugs have a similar effect and their combined effect is equal to the sum of their individual effects. This can lower the blood pressure too much and cause symptoms such as dizziness, fainting, and shock. The nurse should hold the client's scheduled antihypertensive medications and notify the healthcare provider. The nurse should also monitor the client's vital signs, level of consciousness, and perfusion.
