1. Cyanocobalamin is a form of which vitamin?

A. Vitamin B1
B. Vitamin B2
C. Vitamin B3
D. Vitamin B12

Correct answer: D

Rationale: Cyanocobalamin is a synthetic form of Vitamin B12. Vitamin B12 is essential for various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. It is not to be confused with Vitamin B1, B2, or B3, which are separate vitamins with different roles in the body.

2. Complex carbohydrates contain more than 10 monosaccharides. Complex carbohydrates are also called disaccharides.

A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second is false.
D. The first statement is false; the second is true.

Correct answer: C

Rationale: The first statement is true; the second is false. Complex carbohydrates are also called polysaccharides and contain more than 10 monosaccharides. Choice A is incorrect because the second statement is false. Choice B is incorrect because the first statement is true. Choice D is incorrect because the second statement is false.

3. Which mineral is important for the synthesis of thyroid hormones?

A. Iron
B. Zinc
C. Iodine
D. Magnesium

Correct answer: C

Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.

4. A nurse is providing teaching to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

A. Albumin in my urine is an indication of normal kidney function.
B. I will keep my HbA1c at five percent.
C. I will have ketones in my urine if my blood glucose is maintained at 190 milligrams per deciliter.
D. I will keep my blood glucose levels between 200 and 212 milligrams per deciliter.

Correct answer: B

Rationale: The correct answer is B. Maintaining an HbA1c level of 5 percent indicates good long-term blood glucose control and understanding of diabetes management. Choice A is incorrect because the presence of albumin in the urine (albuminuria) is actually an indication of kidney damage in diabetes. Choice C is incorrect as ketones in the urine are a sign of inadequate insulin and can occur when blood glucose levels are high, not at a specific level like 190 mg/dL. Choice D is also incorrect as the client should aim to keep blood glucose levels within a tighter range for better control, typically between 80-130 mg/dL before meals and less than 180 mg/dL after meals.

5. What happens when Mrs. Guevarra, a nurse, delegates aspects of the client's care to the nurse-aide, an unlicensed staff member?

A. Mrs. Guevarra makes the assignment to instruct the staff member
B. Mrs. Guevarra is assigning the responsibility to the aide but not the accountability for those tasks
C. Mrs. Guevarra does not need to directly supervise or evaluate the aide
D. Mrs. Guevarra must know how to perform the task being delegated

Correct answer: C

Rationale: The correct answer is C. While it is true that Mrs. Guevarra is delegating tasks to the nurse-aide, she does not necessarily have to directly supervise or evaluate the aide. She still retains the overall accountability for the care of the client, but direct supervision of the aide is not a requirement for delegation. Choice A is incorrect because the primary purpose of delegation is not instruction. Choice B is also incorrect because although Mrs. Guevarra is delegating tasks, she still retains accountability for those tasks. Finally, choice D is incorrect because the ability to perform the task being delegated is not a requirement for the delegator; the delegatee should have the necessary skills and knowledge to perform the delegated tasks.
