The nurse is administering muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention is the most important for the nurse to implement?

Choice A reason: This is not a correct information for the nurse to include in the discharge instructions. Taking the tablet with a daily multivitamin is not advisable, as some vitamins and minerals, such as calcium, zinc, and vitamin C, can interfere with the absorption of iron and reduce its effectiveness. The client should take the tablet on an empty stomach or with a small amount of food that does not contain these substances.

Choice B reason: This is not a correct information for the nurse to include in the discharge instructions. Bedtime is not the best time to take the tablet, as it may cause gastrointestinal side effects, such as nausea, vomiting, constipation, or diarrhea, that can disrupt the client's sleep and comfort. The client should take the tablet at least 2 hours before or after meals, and preferably in the morning.

Choice C reason: This is a correct information for the nurse to include in the discharge instructions. Waiting 2 hours after meals to take the tablet is recommended, as it ensures that the stomach is empty and that the iron is not affected by any food or beverages that may impair its absorption. The client should also drink plenty of water with the tablet to facilitate its passage and prevent irritation of the esophagus.

Choice D reason: This is not a correct information for the nurse to include in the discharge instructions. Crushing the tablets and mixing with pudding is not appropriate, as it can damage the enteric coating of the tablets, which is designed to protect the iron from being destroyed by the stomach acid and to reduce the gastrointestinal side effects. The client should swallow the tablets whole and not chew, break, or crush them.

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.
