which substance is most essential for hydrolyzing large protein molecules

ATI RN

ATI Nutrition Proctored Exam 2023

1. Which enzyme is most essential for hydrolyzing large protein molecules?

A. Gastric lipase
B. Pepsin
C. Mucus
D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

2. The purpose of ECT in clients with depression is to:

A. Stimulation in the brain to increase brain conduction and counteract depression
B. Mainly Biologic, increasing the norepinephrine and serotonin level
C. Creates a temporary brain damage that will increase blood flow to the brain
D. Involves the conduction of electrical current to the brain to charge the neurons and combat depression

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.

3. This special form is used when the patient is admitted to the unit. The nurse completes the information in this record particularly his/her basic personal data, current illness, previous health history, health history of the family, emotional profile, environmental history as well as physical assessment together with nursing diagnosis on admission. What do you call this record?

A. Nursing Kardex
B. Nursing Health History and Assessment Worksheet
C. Medicine and Treatment Record
D. Discharge Summary

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. What is a disadvantage of using a food frequency questionnaire?

A. It does not influence the food choices of the consumer
B. It is not affected by seasonal changes in the diet
C. It is not effective for monitoring short-term changes in food intake
D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.
