1. What type of debridement involves proteolytic enzymes?

A. Interventional C. Surgical
B. Mechanical D. Chemical
C.
D.

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. During an initial visit with an older adult client living alone and having difficulty preparing meals, what should the home health nurse do first?

A. Discuss nutritional requirements with the client.
B. Refer the client to a senior citizen center.
C. Arrange for a home-delivered meal program.
D. Perform a nutrition screening.

Correct answer: D

Rationale: Performing a nutrition screening is the most appropriate action for the nurse to take first. This allows the nurse to assess the client's current nutritional status and identify any specific needs. Discussing nutritional requirements with the client (Choice A) may be important but should come after the initial assessment. Referring the client to a senior citizen center (Choice B) or arranging for a home-delivered meal program (Choice C) are actions that may be considered later based on the findings of the nutrition screening.

3. What physiological role does phosphorus play in the body?

A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
B. Calcium homeostasis, structural integrity of heart muscle
C. No known metabolic function, caries-preventing properties
D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

4. What are the responsibilities of a nurse towards a patient?

A. A registered nurse is responsible for a group of patients from their admission to their discharge
B. A registered nurse only provides care for the patient with the assistance of nursing aides
C. A nurse's only responsibility is to perform administrative duties in a healthcare setting
D. A nurse's only responsibility is to maintain hospital equipment

Correct answer: A

Rationale: A registered nurse is responsible for a group of patients from their admission to their discharge. This responsibility encompasses assessing patient needs, formulating care plans, administering medications, monitoring patient progress, and coordinating with other members of the healthcare team. Choice B is not entirely accurate because, even though nurses often work with nursing aides, the nurses themselves hold the ultimate responsibility for the overall care of the patient. Choices C and D are incorrect as they depict an incomplete and inaccurate representation of a nurse's role, which extends beyond administrative duties and equipment maintenance to primarily focus on direct patient care.
