A nurse is assessing a client who has Lewy body dementia. The nurse should recognize that which of the following is responsible for changes in thinking, communication, movement, and emotional processing in Lewy body dementia?

A. Lie on your back when sleeping: Lying on the back when sleeping may be recommended initially after cochlear implant surgery to avoid putting pressure on the surgical site. However, this instruction should not be included in the plan of care indefinitely. Once the client is comfortable and the surgical site is healing well, they should be allowed to sleep in any position that is comfortable for them.

B. Lie on your front when sleeping: Lying on the front when sleeping is not typically recommended after cochlear implant surgery, as it may put pressure on the surgical site and disrupt healing. This position could potentially cause discomfort and increase the risk of complications. Therefore, this instruction should not be included in the plan of care.

C. Resume your exercise routine: Resuming the exercise routine immediately after cochlear implant surgery may not be advisable. The client should be instructed to avoid strenuous activities and heavy lifting for a certain period as advised by the healthcare provider. Engaging in vigorous exercise too soon after surgery could potentially disrupt the healing process and increase the risk of complications. Therefore, this instruction should not be included in the plan of care immediately after surgery.

D. Wash your hair 24 hr after surgery: After cochlear implant insertion, it is important to keep the surgical site clean to prevent infection. Washing the hair 24 hours after surgery helps to maintain cleanliness and hygiene without disrupting the surgical site. It is typically safe to wash the hair after this period as long as gentle care is taken to avoid excessive manipulation of the implant site.

Pantoprazole: Pantoprazole is a proton pump inhibitor commonly used to reduce stomach acid production. It is primarily indicated for the treatment of gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions related to excessive stomach acid production. It does not play a role in managing Meniere's disease, which is a disorder of the inner ear characterized by episodes of vertigo, tinnitus, and hearing loss.

B) Warfarin: Warfarin is an anticoagulant medication used to prevent blood clot formation. It is commonly prescribed for conditions such as atrial fibrillation, deep vein thrombosis, and pulmonary embolism. Meniere's disease does not typically require anticoagulant therapy, so warfarin would not be indicated for its treatment.

C) Furosemide: Furosemide is a loop diuretic that helps reduce fluid retention by increasing urine output. In some cases of Meniere's disease, especially those associated with excessive endolymphatic fluid buildup in the inner ear, furosemide may be prescribed to help reduce fluid volume and alleviate symptoms such as vertigo and pressure sensation in the ear.

D) Oxybutynin: Oxybutynin is an anticholinergic medication primarily used to treat overactive bladder and urinary incontinence. It works by relaxing smooth muscle in the bladder, reducing bladder spasms and urinary urgency. While some individuals with Meniere's disease may experience associated symptoms such as frequent urination or urinary urgency, oxybutynin is not a standard treatment for Meniere's disease itself.
