Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.

Correct Answer: B

Rationale: In the community setting, the essential record about the patient is the patient's chart. This chart contains all important information about the patient, including medical history, treatment plans, medications, progress notes, and any other pertinent information related to the patient's care. It serves as a crucial document for healthcare providers to track and monitor the patient's health status, facilitate communication among team members, ensure continuity of care, and make informed clinical decisions. The patient's chart is a comprehensive and centralized source of information that guides the delivery of quality care in the community setting.

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.

Correct Answer: B

Rationale: Breast tenderness is a hallmark symptom of premenstrual syndrome (PMS), which occurs in the days leading up to menstruation. This symptom is often associated with hormonal fluctuations during the menstrual cycle. Women may experience increased sensitivity and soreness in their breasts, making them feel tender or swollen. It is a common symptom of PMS and can vary in severity from one individual to another. Pelvic pain, postmenopausal bleeding, and dyspareunia are not typically considered hallmark symptoms of PMS.

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.
