Rationale: When assessing for malnutrition, nurses should consider multiple risk factors. Dental problems and depression can impact a person's ability to eat and maintain proper nutrition. The ability to read and write may not directly relate to malnutrition risk. The correct answer is 'All of the above' because dental problems and depression are indeed risk factors, along with other factors like the inability to prepare meals and the loss of a spouse.

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.

Correct Answer: C

Rationale: In this situation, the first step should be to report the matter to your supervisor. It is essential to notify the appropriate authority immediately to address the discrepancy in the narcotics cabinet. Choice A is not the first step as reporting to the nursing director should follow after informing the supervisor. Keeping the findings to yourself (Choice B) is not appropriate as it may jeopardize patient safety and is against ethical standards. While finding out which patient received narcotics (Choice D) is important, it is not the immediate action to take in this scenario.

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.

Correct Answer: C
