1. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.

Correct answer: A

Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.

2. Men generally have a higher RDA than women, except during pregnancy and lactation when women’s nutritional needs increase significantly.

Correct answer: A

Rationale: The statement is TRUE. Men typically require a higher Recommended Dietary Allowance (RDA) than women due to physiological differences. However, during pregnancy and lactation, women's nutritional needs increase significantly to support the growth and development of the baby. Therefore, during these stages, women may require a higher RDA compared to men. This exception is crucial to consider when evaluating nutritional requirements based on gender.

3. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

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.

4. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

5. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?

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.
