Correct Answer: D

Rationale: The correct answer is D: Ask clear, simple questions using concrete language. This strategy is most helpful because older adults with schizophrenia may have cognitive impairments that affect their ability to process complex information. Clear and simple questions using concrete language can help the patient understand and respond effectively. Choice A (Ask questions that can be answered with yes or no) limits communication and may not provide enough information for the nurse to assess the patient's condition comprehensively. Choice B (Use silence often and let the patient take the lead) may not be effective as the patient may struggle to communicate effectively due to cognitive impairments. Choice C (Use open-ended, indirect questions) may lead to confusion or misinterpretation for a patient with cognitive challenges.

Correct Answer: B

Rationale: The correct answer is B because it captures the essence of bereavement - the experience of loss. This choice acknowledges that bereavement involves losing something significant, which is a universal aspect of grieving. Other choices are incorrect - A is not always predictable, C is not always acute depression, and D focuses on a specific aspect of grief rather than the core element of loss. Therefore, B is the most comprehensive and inclusive choice.

Correct Answer: B

Rationale: The correct answer is B because nurses are expected to encourage patients' involvement in therapies to promote holistic care and enhance patient outcomes. By understanding different types of therapies, nurses can educate and motivate patients to participate actively in their treatment plans. This empowers patients to take control of their health and improve their overall well-being. Choices A, C, and D are incorrect because the primary role of the nurse in this context is to support and advocate for the patients' engagement in therapies, rather than focusing on cost-effectiveness, placement, or support of other team members.

Correct Answer: B

Rationale: The correct answer is B: To prevent anoxia due to medication-induced paralysis of respiratory muscles. During electroconvulsive therapy, muscle relaxants are often used to prevent injury during the seizure. These medications can lead to paralysis of respiratory muscles, causing potential anoxia if oxygen is not administered. Providing pure oxygen ensures adequate oxygenation despite muscle paralysis. Incorrect Choices: A: Preventing increased intracranial pressure is not the primary rationale for administering oxygen during ECT. C: Hypotension, bradycardia, and bradypnea are potential side effects of ECT itself, but oxygen administration is not primarily to prevent these. D: Oxygen is not administered to prevent a blocked airway but rather to ensure adequate oxygenation during muscle paralysis.

Correct Answer: A

Rationale: The correct answer is A because the patient whose 16-year-old daughter was raped and killed while going on an errand for the patient is at highest risk for dysfunctional grief. This traumatic and unexpected loss of a child to a violent act can lead to complicated or prolonged grief reactions. The sudden and violent nature of the death, along with the added trauma of rape, can significantly impact the grieving process. The intense emotions and feelings of guilt, anger, and helplessness may complicate the bereavement process and lead to dysfunctional grief reactions. Summary: Choice B is incorrect because the death of an 86-year-old mother after a long illness, although sad, does not necessarily indicate a higher risk of dysfunctional grief. Choice C is incorrect as attending a support group and receiving assistance from hospice are positive factors that can support healthy grieving. Choice D is incorrect as attending a bereavement group and learning to express feelings after the deaths of twin daughters indicate active engagement in the grieving process, which is
