Correct Answer: C

Rationale: The correct answer is C. Cholesteatomas are often the result of chronic otitis media. Chronic otitis media can lead to the formation of cholesteatomas, which are noncancerous but can cause complications if left untreated. Cholesteatomas do not resolve spontaneously (A), are not the result of metastasis (B), do not typically cause intractable neuropathic pain (D), and usually require surgical removal to prevent complications (E). Therefore, educating the patient about the association between chronic otitis media and cholesteatoma is essential for understanding the diagnosis and potential treatment options.

Correct Answer: D

Rationale: Rationale: 1. Indispensable amino acids, also known as essential amino acids, must be obtained through the diet as the body cannot synthesize them. 2. Amino acids are the building blocks of proteins, so mentioning "indispensable amino acids" indicates understanding of essential dietary proteins. 3. Triglycerides are fats, not proteins, and not related to essential amino acids. 4. Dispensable amino acids can be synthesized by the body, so mentioning them would not indicate understanding of essential proteins.

Correct Answer: A

Rationale: The correct answer is A: Teach the patient how to self-cath the pouch. In a continent urinary reservoir, patients need to catheterize the pouch several times a day. This is essential for emptying the urine from the pouch as the ileocecal valve creates a one-way valve. Teaching the patient how to self-catheterize ensures proper and timely drainage, preventing complications like urinary retention. Self-catheterization also empowers the patient to take an active role in managing their continence. Summary of other choices: B: Kegel exercises are ineffective for a patient with a continent urinary reservoir as they do not address the need for catheterization. C: Changing the collection pouch is not the primary action needed for a continent urinary reservoir. Catheterization is essential for drainage. D: The Valsalva technique is not appropriate for voiding in a continent urinary reservoir. Catheterization is the recommended method for emptying the pouch.

Correct Answer: D

Rationale: The correct answer is D: Frequent douching. Douching disrupts the natural balance of vaginal flora, making the environment more susceptible to infections. High estrogen levels (A) can actually protect against vaginal infections. Late menarche (B) and nonpregnant state (C) are not direct risk factors for vaginal infections. In summary, frequent douching is the most significant risk factor as it disrupts the vaginal microbiome.

Correct Answer: A

Rationale: The correct answer is A because macular degeneration is a leading cause of blindness in older adults. The macula is responsible for central vision, crucial for tasks like reading and driving. Macular degeneration can lead to permanent vision loss if not managed promptly. The other choices are less likely to result in blindness: astigmatism, hyperopia, and myopia are refractive errors that can be corrected with glasses or contacts, and they do not typically lead to blindness. The age and condition of the patient are important factors in determining the risk of blindness.
