Correct Answer: B

Rationale: Sundowning is a phenomenon commonly seen in elderly individuals, particularly those with cognitive impairments like dementia, where they become more restless, anxious, confused, or agitated during late afternoon and evening hours, typically around sunset. This change in behavior can manifest as increased confusion, wandering, aggression, or vocalization. The exact cause of sundowning is not completely understood but may involve a combination of factors such as disruptions in the sleep-wake cycle, fatigue, decreased lighting, and hormonal imbalances. Managing sundowning behaviors may involve environmental modifications, maintaining a regular routine, ensuring proper lighting, and addressing any underlying medical conditions contributing to the behavior changes.

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: D

Rationale: A delimitation in a research study refers to setting specific boundaries or restrictions on the scope of the study. In this scenario, Gloria's decision to include only nurses with a minimum of three years experience as psychiatric nurses is a delimitation because it sets a specific criterion or boundary for the selection of participants. This helps to focus the study on a particular group of individuals who possess the required experience, ensuring the research is targeted and relevant to the topic being investigated.

Correct Answer: A

Rationale: Battery refers to the intentional and offensive physical contact with another person without their consent, resulting in harm or injury. In this scenario, the victim clearly expressed their unwillingness to be touched or helped by saying, "Don't touch me!" multiple times. By ignoring the victim's refusal and physically forcing them into the ambulance, the EMT is committing battery even though they may have had good intentions to provide assistance. It is important for medical professionals, including EMTs, to always respect a person's right to refuse medical treatment or assistance, even in emergency situations.

Correct Answer: D

Rationale: During the active phase of labor, a cervical dilation of 6 cm and regular contractions lasting 60 seconds each, occurring every 3 minutes indicate good progress in labor. The nurse should continue to monitor the progress closely by assessing the mother's vital signs, fetal heart rate, and the pattern of contractions. It is important to provide support and encouragement to the mother, continue with comfort measures, and be prepared to assist with the delivery when the cervix is fully dilated. This stage of labor is focused on active dilation and effacement of the cervix, and it is not yet time for the mother to push or for the nurse to administer oxytocin to augment labor.
