1. Which of the following provides the least amount of potassium?

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

2. Which mineral is essential for wound healing?

Correct answer: C

Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.

3. Each statement is true of proteins, except one. Which is the exception?

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.

4. Induction of vomiting is indicated for the accidental poisoning patient who has ingested.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Based on universally-accepted color codes, what color would you expect a tank containing nitrous oxide (laughing gas) to have?

Correct answer: A

Rationale: The correct answer is A: Red. In the medical field, tanks containing nitrous oxide (laughing gas) are typically color-coded with a specific color for easy identification. Nitrous oxide tanks are commonly labeled with a red color code. This color-coding system helps healthcare providers quickly and accurately identify the contents of the tanks, reducing the risk of errors in administering gases to patients. Choices B, C, and D are incorrect because the universally-accepted color for nitrous oxide tanks is red, not blue, green, or orange.
