Correct Answer: C

Rationale: In a postpartum client exhibiting signs of anxiety, restlessness, and palpitations, it is essential to prioritize notifying the healthcare provider immediately. These symptoms could indicate a serious condition such as postpartum preeclampsia, postpartum hemorrhage, or postpartum cardiomyopathy, which require urgent medical attention. It is crucial to rule out any life-threatening conditions and ensure the client receives appropriate treatment promptly. While relaxation techniques and deep breathing exercises can be helpful for anxiety management in some cases, in this situation, the priority is to ensure the client's safety and well-being by seeking medical evaluation and intervention. Administering a benzodiazepine without consulting the healthcare provider first could potentially mask symptoms or interact with other medications the client may be taking, making it unsafe to proceed without professional guidance.

Correct Answer: D

Rationale: Restlessness caused by pain often manifests as increased perspiration and constant change of position. When a person is in pain, they may become sweaty or clammy due to increased sympathetic nervous system activity. Additionally, they may constantly shift or fidget in an attempt to find a more comfortable position that can alleviate the pain they are experiencing. Therefore, it is crucial for Nurse Chona to accurately document these behaviors as signs of pain-related restlessness. Difficulty of breathing (Option A), increased respiratory rate and blood pressure (Option B), and increased heart rate (Option C) are more indicative of hypoxia or respiratory distress rather than pain-related restlessness.

Correct Answer: A

Rationale: The nurse should prioritize adjusting the irrigation flow rate based on the patient's urine output to prevent complications during continuous bladder irrigation (CBI). Proper adjustment of the irrigation flow rate helps maintain adequate bladder drainage while preventing bladder distention, clot formation, and potential irrigation fluid overload. Monitoring the patient's urine output and adjusting the flow rate accordingly ensures optimal functioning of the CBI system and enhances patient safety. This proactive approach minimizes the risk of complications and promotes effective postoperative care following urological surgery.

Correct Answer: C

Rationale: In a pregnant patient with suspected pulmonary embolism (PE), the most appropriate imaging modality for evaluation is contrast-enhanced computed tomography (CT) pulmonary angiography. This imaging technique has been shown to be safe for the fetus when necessary, especially if the benefits of making a diagnosis outweigh the minimal risks associated with radiation exposure. It provides quick and accurate detection of PE with high sensitivity and specificity.

Correct Answer: B

Rationale: Phenomenology is a qualitative research design that focuses on exploring and understanding the lived experiences of individuals within their "life-worlds." It seeks to uncover the essence of a phenomenon as it is experienced subjectively by individuals, aiming to understand the underlying meanings and perspectives through in-depth interviews, observations, and reflections. In phenomenology, researchers aim to set aside their own biases and preconceptions to capture the essence of the participants' experiences as they see them. This approach allows researchers to gain insight into how individuals make sense of and interpret their world, providing rich and detailed accounts of unique human experiences.
