1. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?

Correct answer: D

Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.

2. What instruction should the nurse include on weight gain during pregnancy?

Correct answer: A

Rationale: Appropriate weight gain is crucial for reducing the risk of preterm birth.

3. A nurse is instructing teenage girls on the importance of adequate calcium intake throughout their life span to prevent complications. Which complication should the nurse include in the teaching?

Correct answer: B

Rationale: The correct answer is B: Osteoporosis. Adequate calcium intake throughout life helps prevent osteoporosis, a condition characterized by weak and brittle bones, which is common in older adults. Goiter is caused by an iodine deficiency, not calcium. Heart disease is more related to factors like cholesterol and blood pressure. Dental caries are primarily influenced by oral hygiene and sugar intake, not just calcium.

4. When rickets occurs, how is the alveolar bone affected compared to other bones in the body?

Correct answer: A

Rationale: Both statements are true. When rickets occurs, the alveolar bone is affected similar to other bones in the body, with the trabeculae of the alveolar bone also weakening. In addition to damaged alveolar bone caused by vitamin D deficiency, dental changes include delayed dentition and small molars. The other choices are incorrect because both statements provided are accurate based on the effects of rickets on the alveolar bone.

5. The nurse understands that one of these factors contributes to constipation:

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.
