Correct Answer is B
Explanation
Choice A reason: This choice is incorrect. While postpartum depression can increase suicide risk, it does not have the highest correlation with completed suicide.
Choice B reason: This is the correct choice. Older male clients, especially those living in rural areas, have a higher risk of completing suicide due to factors like isolation and access to lethal means.
Choice C reason: This choice is incorrect. Being married and having a new baby can be protective factors against suicide.
Choice D reason: This choice is incorrect. While stress from school can contribute to suicide risk, it does not typically pose the highest risk compared to other factors.
Correct Answer is A
Explanation
Choice A reason: This is the correct choice. Given the client has not eaten for several days, addressing nutritional needs is a priority to prevent further physical health complications.
Choice B reason: While there may be a risk for violence, the immediate physical health needs related to nutrition are more pressing.
Choice C reason: Ineffective health maintenance may be a concern, but it is not as immediate as the risk posed by imbalanced nutrition.
Choice D reason: There is no indication in the text that the client is at risk for suicide; therefore, this would not be the priority without further assessment.
