Nursing Elites

1. What stimulates bile secretion from the liver to the small intestine?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: C

Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.

2. For an incontinent elderly client who frequently wets his bed and develops redness and skin excoriation at the perianal area, what is the best nursing goal?

• A. Ensure that the bed linen is always dry
• B. Frequently check the bed for wetness and keep it dry
• C. Place a rubber sheet under the client's buttocks
• D. Keep the patient clean and dry

Correct answer: A

Rationale: The best nursing goal for an incontinent elderly client with skin excoriation is to ensure that the bed linen is always dry. This helps in preventing further skin breakdown and promoting skin integrity. Choice B, to frequently check the bed for wetness and keep it dry, may not address the issue of prevention if the linen is not consistently dry. Choice C, placing a rubber sheet under the client's buttocks, focuses more on protecting the mattress rather than addressing the client's skin condition directly. Choice D, keeping the patient clean and dry, is important but does not specifically address the preventive aspect of maintaining dry bed linen.

3. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

• A. 5
• B. 5.5
• C. 6
• D. 6.5

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.

4. What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?

• A. Avoid foods such as smoked meats and frozen dinners.
• B. Select foods with less than 4g of sodium as indicated on food labels.
• C. Use soy sauce for flavoring foods instead of table salt.
• D. Processed and prepared foods are typically low in sodium.

Correct answer: A

Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.

5. What are symptoms of uncontrolled type 1 diabetes?

• A. Depression, anxiety, and fatigue
• B. Increased thirst, urination, and hunger
• C. Weight gain, macrosomia, and food cravings
• D. Poor wound healing, blurred vision, and recurrent infections

Correct answer: B

Rationale: The correct answer is B: Increased thirst, urination, and hunger. Uncontrolled type 1 diabetes typically presents with classic symptoms including polydipsia (increased thirst), polyuria (frequent urination), and polyphagia (increased hunger). These symptoms are often accompanied by weight loss due to the body's inability to properly utilize glucose for energy. Choices A, C, and D are incorrect as they do not align with the typical symptoms of uncontrolled type 1 diabetes. Depression, anxiety, fatigue, weight gain, macrosomia, food cravings, poor wound healing, blurred vision, and recurrent infections are not primary symptoms associated with uncontrolled type 1 diabetes.
