1. Which of the following nutrients deficiency may lead to a diabetes-like condition?

• A. chromium
• B. iron
• C. molybdenum
• D. selenium

Correct answer: A

Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.

2. You are taking care of critically ill client and the doctor in charge calls to order a DNR (do not resuscitate) for the client. Which of the following is the appropriate action when getting DNR order over the phone?

• A. Have the registered nurse, family spokesperson, nurse supervisor and doctor sign
• B. Have 2 nurse validate the phone order, both nurses sign the order and the doctor should sign his order within 24
• C. Have the registered nurse, family and doctor sign the order
• D. Have 1 nurse take the order and sign it and have the doctor sign it within 24 hours

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. 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.

4. What side effect is commonly associated with ECT?

• A. Transient loss of memory, confusion, and disorientation
• B. Nausea and vomiting
• C. Fractures
• D. Hypertension and increased heart rate

Correct answer: A

Rationale: The correct answer is A, as Electroconvulsive Therapy (ECT) is commonly associated with side effects such as transient loss of memory, confusion, and disorientation. While nausea and vomiting (Choice B) can occur, they are not as common as the memory-related side effects. Fractures (Choice C) are unlikely unless a mishap occurs during the procedure. Hypertension and increased heart rate (Choice D) might occur during the procedure due to the physiological stress of the treatment, but these are not the most commonly associated side effects. The rationale provided did not effectively explain this, so it's important to note that ECT is a procedure often used for severe depression and other mental illnesses, and understanding its side effects is crucial for patient safety and effective care.

5. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?

• A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
• C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.

Correct answer: A

Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.
