Correct Answer: C

Rationale: The suicide of her mother is the most probable historical data that led to post-traumatic stress disorder. Experiencing the suicide of a close family member, especially a parent, can be an extremely traumatic event that can have long-lasting psychological effects. Witnessing or dealing with such a tragic loss can lead to feelings of helplessness, depression, guilt, and intense emotional distress, all of which are common in individuals with post-traumatic stress disorder (PTSD). This significant and distressing event could have a profound impact on the individual's mental health and well-being, contributing to the development of PTSD symptoms such as intrusive memories, avoidance behaviors, negative mood alterations, and changes in arousal or reactivity.

Correct Answer: B

Rationale: The patient who had a left total hip replacement surgery due to osteoarthritis needs to strictly follow the postoperative teaching of being shown how to gently irrigate the external auditory canal because this instruction is unrelated to a hip replacement surgery. The other options are not relevant to the surgery and patient's condition. Option A about airplane travel, Option C about dizziness, and Option D about hair washing are not appropriate instructions for a patient who had a hip replacement. It is important for healthcare providers to give accurate and relevant postoperative instructions to help the patient recover successfully.

Correct Answer: D

Rationale: It is important for the nurse to explore Ella's feelings further when she expresses thoughts of wishing to be dead and struggling with not having someone around. These statements indicate that Ella may be experiencing emotional distress or depression, which require immediate attention. By exploring Ella's feelings, the nurse can assess the severity of her emotional state, provide appropriate support, and potentially prevent any harm or self-harm. It is crucial to address and validate her emotions, as well as to initiate necessary interventions to ensure her safety and well-being.

Correct Answer: B

Rationale: Obtaining informed consent is primarily the responsibility of the physician. Informed consent is a crucial ethical and legal concept in healthcare that requires the healthcare provider, usually the physician, to ensure that the patient understands the proposed treatment, including the risks, benefits, alternatives, and potential outcomes, before agreeing to proceed with the treatment. While other healthcare professionals, such as nurses, nurse managers, anesthesiologists, and midwives, may also play a role in the informed consent process by providing information and clarifying details, it is ultimately the physician who must obtain the patient's informed consent before any treatment or procedure is performed.

Correct Answer: C

Rationale: The correct answer, C, reflects a health resource problem. The absence of a midwife in the community means that there is a lack of a critical health resource necessary for providing essential health services, especially for pregnant women and infants. This directly impacts the access to healthcare services and can contribute to negative health outcomes, such as high maternal mortality rates. The other options do not directly address a health resource problem but rather focus on specific issues or conflicts within the community.
