Correct Answer: A

Rationale: Beta-blockers are medications commonly used in the management of heart failure. One of the therapeutic effects of beta-blockers is to decrease the heart rate. By blocking the action of adrenaline on the heart, beta-blockers help to slow down the heart rate, reduce the workload on the heart, and improve overall heart function. In patients with heart failure, a decreased heart rate is a favorable outcome as it can help improve cardiac output and reduce symptoms of heart failure such as fatigue and shortness of breath. Monitoring the heart rate is an important assessment parameter to evaluate the effectiveness of beta-blocker therapy in patients with heart failure. Therefore, a decreased heart rate would indicate a therapeutic effect of beta-blocker therapy in this patient.

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: C

Rationale: In this situation, it is crucial for the nurse to inform the surgeon immediately and request corrective action. Maintaining a sterile field during surgical procedures is essential to prevent infections and ensure patient safety. Any break in sterile technique should be addressed promptly to prevent any potential harm to the patient. By informing the surgeon immediately, corrective action can be taken promptly to maintain the sterility of the surgical field and minimize the risk of complications. Reporting the incident to the surgeon also allows for immediate intervention and re-education of the team member involved in the break in sterile technique.

Correct Answer: B

Rationale: Acknowledging the patient's emotions and offering empathy and support is the most appropriate response in this situation. It is important for the nurse to show understanding and compassion towards the patient, especially when they are feeling emotional about a recent diagnosis. By acknowledging the patient's emotions, the nurse can create a supportive environment that facilitates open communication and helps the patient feel heard and valued. This approach can also help build trust between the patient and the nurse, leading to better outcomes in terms of patient care and overall well-being. Ignoring the patient's emotions, telling them to stop being emotional, or changing the subject may make the patient feel dismissed or isolated, which could negatively impact their mental and emotional state. Thus, offering empathy and support is key in helping the patient cope with their emotions and navigate through their diagnosis.

Correct Answer: A

Rationale: When a woman in active labor is experiencing intense pain and requests non-pharmacological pain relief measures, the nurse should prioritize providing continuous labor support. Continuous labor support, also known as a doula or labor companion, has been shown to be effective in reducing the perception of pain and improving labor outcomes. The presence of a supportive person can provide physical, emotional, and informational support, helping the woman cope with the pain and navigate through the labor process. This intervention can enhance the woman's overall experience of labor and improve maternal and neonatal outcomes without the need for pharmacological interventions. Administering opioids, performing epidural analgesia, or initiating nitrous oxide inhalation are pharmacological pain relief measures and may not align with the woman's preference for non-pharmacological options.
