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.

Correct Answer: C

Rationale: The correct answer is C. The client whose stomach does not produce intrinsic factors is most likely to need regular injections of vitamin B12. Intrinsic factor is essential for the absorption of vitamin B12. Without intrinsic factor, the client cannot absorb vitamin B12 from food, necessitating the need for regular injections. Choices A, B, and D do not directly impact the production of intrinsic factors in the stomach, so they are less likely to result in the need for vitamin B12 injections.

Correct Answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
