1. Each statement is true of calcium within saliva, except one. Which is the exception?
- A. Saliva is supersaturated with calcium.
- B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
- C. Calcium and phosphate in saliva provide a buffering action.
- D. Calcium within saliva increases dental caries.
Correct answer: D
Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.
2. A client receiving continuous enteral tube feeding reports cramping and abdominal distention. Which of the following actions should the nurse take?
- A. Check for gastric residual.
- B. Apply low intermittent suction.
- C. Increase the rate of the feeding.
- D. Request a higher-fat formula.
Correct answer: A
Rationale: When a client on continuous enteral tube feeding experiences cramping and abdominal distention, the nurse should check for gastric residual. This assessment helps determine if the client is tolerating the feeding well or if there is a potential issue such as feeding intolerance. Applying low intermittent suction, increasing the feeding rate, or requesting a higher-fat formula are not appropriate actions for addressing the reported symptoms and may exacerbate the client's discomfort or lead to further complications.
3. Furosemide (Lasix) is a drug used to _____.
- A. activate vitamin D
- B. stimulate appetite
- C. lower cholesterol
- D. mobilize fluids
Correct answer: D
Rationale: Furosemide is a diuretic that helps mobilize fluids by increasing urine output, often used to treat conditions like edema and heart failure.
4. A client with type 1 diabetes mellitus asks a nurse for a sweetener recommendation. Which of the following recommendations should the nurse make?
- A. Corn syrup
- B. Natural honey
- C. Nonnutritive sugar substitute
- D. Guava nectar
Correct answer: C
Rationale: The correct recommendation for a client with type 1 diabetes mellitus looking for a sweetener is a nonnutritive sugar substitute. Nonnutritive sugar substitutes do not significantly affect blood glucose levels, making them a suitable option for individuals with diabetes. Corn syrup and natural honey are high in sugar and can lead to spikes in blood glucose levels, which is not ideal for someone with diabetes. Guava nectar, while natural, is also high in sugar content and not recommended for individuals with diabetes.
5. The nurse is completing a nutritional assessment on a client. Which statement made by the client is most concerning to the nurse?
- A. "I notice when I take a vitamin E supplement, I bruise more easily."
- B. "I work nights and rarely go outside during the day."
- C. "I take warfarin, so I need to limit the amount of green leafy vegetables I eat."
- D. "My vitamin supplement has the recommended daily allowance of vitamin A."
Correct answer: A
Rationale: The correct answer is A. Excessive intake of vitamin E can increase the risk of bleeding as it acts as a blood thinner. Bruising easily may indicate too much vitamin E. Choice B is not as concerning as it describes a lifestyle that may lead to vitamin D deficiency due to lack of sunlight exposure. Choice C shows awareness of the interaction between warfarin and vitamin K, which is expected. Choice D indicates knowledge of the vitamin A content in the supplement, which is not a cause for concern.
