1. In the recent technological innovations, which of the following describe researches that are made to improve and make human life easier?
- A. Pure research
- B. Basic research
- C. Applied research
- D. Experimental research
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
2. Which enzyme is most essential for the digestion of triglycerides found in butterfat?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct answer: A
Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.
3. 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.
4. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?
- A. Old Recommended Dietary Allowances (RDA)
- B. Estimated Average Requirement (EAR)
- C. New Recommended Dietary Allowances (RDA)
- D. Tolerable Upper Intake Level (UL)
Correct answer: B
Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.
5. The ideal time to begin taking folate to prevent neural tube defects is:
- A. Before conception
- B. Once pregnancy begins
- C. At 6 weeks
- D. Upon completion of the first trimester
Correct answer: A
Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.
