Correct Answer: A

Rationale: Confirmability is the criteria of trustworthiness that refers to the degree to which the findings of a study are based on the data itself and not on the biases, motivations, or interests of the researchers. In this scenario, returning to the participants to confirm the accuracy of the emerged themes is a way to ensure the confirmability of the study findings. By involving the participants in the validation process, the researchers are seeking to verify that the themes identified truly reflect the experiences of the pregnant women in labor as reported by the participants. This practice enhances the credibility and trustworthiness of the study's findings by confirming their alignment with the participants' perspectives and experiences.

Correct Answer: B

Rationale: In an educational program conducted by a nurse, it is crucial to involve the patient, their family, and significant others. This approach ensures holistic care by considering the patient's psychosocial environment, family dynamics, and support system. Including these individuals in the educational program fosters collaboration, strengthens the patient-nurse relationship, and equips family members with the knowledge and skills needed to provide optimal care at home. Furthermore, involving the patient's support system can enhance adherence to treatment plans and contribute to better health outcomes. Therefore, the presence and cooperation of the patient, family, and significant others are essential elements of a successful educational program led by a nurse.

Correct Answer: A

Rationale: An occiput posterior fetal position, where the baby's head is facing the mother's abdomen rather than her back, can lead to prolonged and severe back pain during labor. This position can cause irregular contractions and difficulty in descending through the birth canal, resulting in abnormal labor progress. The back pain experienced in this case is often intense due to the pressure exerted on the mother's lower back and may also be associated with intense back labor. It is essential for the nurse to recognize this potential issue and assist in maneuvers or positions to help the baby rotate to a more optimal position for delivery.

Correct Answer: A

Rationale: The purpose of a tracheostomy is to establish an artificial airway in the trachea through a surgical procedure. This is done to bypass obstructions in the upper airway, assist with breathing, or facilitate the removal of secretions from the lungs. A tracheostomy helps in maintaining a clear and secure airway for patients who have difficulty breathing or require long-term mechanical ventilation support.

Correct Answer: A

Rationale: Zenker's diverticulum is a condition in which there is a pouch or sac that forms at the posterior pharyngeal wall above the upper esophageal sphincter. It can present with symptoms such as sensation of a foreign body stuck in the throat, difficulty swallowing (dysphagia), and odynophagia (painful swallowing). Flexible laryngoscopy can reveal a submucosal mass arising from the posterior pharyngeal wall, which is characteristic of Zenker's diverticulum.
