1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?
- A. 10-15 seconds
- B. 30-35 seconds
- C. 20-25 seconds
- D. 0-5 seconds
Correct answer: D
Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.
2. The substance that is most supportive of bones and teeth is:
- A. Hemoglobin
- B. Collagen
- C. Insulin
- D. Pepsin
Correct answer: B
Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.
3. To follow a healthy diet, a person should be sure that:
- A. 20-35% of the total carbs eaten should be made up of fiber
- B. 45-65% of the total carbs eaten should be made up of fiber
- C. 45-65% of the total fiber eaten should be made up of soluble fiber
- D. 45-65% of the total calories eaten should be made up of carbs
Correct answer: D
Rationale: The Acceptable Macronutrient Distribution Range (AMDR) suggests that 45-65% of total daily calories should come from carbohydrates.
4. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?
- A. Ionic bond
- B. Covalent bond
- C. Functional group
- D. Metallic bond
Correct answer: A
Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
5. A nurse is caring for an antepartum client who has iron-deficiency anemia. When teaching the client about nutrition, the nurse should emphasize the need for an increased intake of which of the following foods?
- A. Milk and cheese
- B. Red meat and organ meat
- C. Fresh fruits
- D. Whole grain breads
Correct answer: B
Rationale: The correct answer is red meat and organ meat. These foods are rich sources of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Red meat and organ meat can significantly help in increasing the iron levels in individuals with iron-deficiency anemia, especially in antepartum clients. Fresh fruits, while nutritious, do not provide high amounts of iron. Milk and cheese are not the best sources of iron for individuals with iron-deficiency anemia. Whole grain breads also do not contain as much bioavailable iron as red meat and organ meat.
