1. A nurse is caring for a client who is well-hydrated and who demonstrates no evidence of anemia. Which of the following laboratory values gives the nurse an assessment of the adequacy of the client's protein uptake and synthesis?
- A. Albumin
- B. Calcium
- C. Sodium
- D. Potassium
Correct answer: A
Rationale: The correct answer is Albumin. Albumin is a protein made by the liver and is a key indicator of the body's protein status. Low levels of albumin can indicate inadequate protein intake or synthesis. Choices B, C, and D (Calcium, Sodium, and Potassium) are not direct indicators of protein uptake and synthesis. Calcium is related to bone health, Sodium to fluid balance, and Potassium to nerve and muscle function.
2. The working phase in a therapy group is usually characterized by which of the following?
- A. Caution
- B. Cohesiveness
- C. Confusion
- D. Competition
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.
3. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?
- A. A single exposure to a large quantity
- B. A single exposure to a small quantity
- C. Multiple exposures of small quantities
- D. Multiple exposures followed by chewing sugarless gum
Correct answer: C
Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.
4. Almost all (99%) of the calcium in the body is used for?
- A. regulating the transmission of nerve impulses
- B. providing energy for cells
- C. providing rigidity for the bones
- D. regulating muscle contraction
Correct answer: C
Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.
5. Electrolytes create _____, which is caused by water following electrolytes within or between cells.
- A. energy
- B. active transport
- C. passive diffusion
- D. osmotic pressure
Correct answer: D
Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.
