Correct Answer: C

Rationale: When caring for patients with hyperbilirubinemia, the nursing care plan should focus on informing the significant others, preventing injury, and preventing complications. The primary goal in managing hyperbilirubinemia is to prevent complications associated with high bilirubin levels, such as kernicterus. Therefore, maintaining physiological homeostasis with bilirubin levels increasing would not be appropriate and should not be the focus of the nursing care plan. It is crucial to monitor and manage bilirubin levels to prevent adverse outcomes rather than allowing them to increase.

Correct Answer: A

Rationale: The presentation of chest pain, dyspnea, hypotension, right ventricular dilation, and hypokinesis on echocardiogram is highly suggestive of a pulmonary embolism. In pulmonary embolism, a blood clot obstructs the pulmonary artery or one of its branches, leading to increased pressure in the right ventricle, which can cause right ventricular dilation and dysfunction. This results in the classic signs of right heart strain on echocardiogram. The patient may also present with symptoms of acute right heart failure, such as chest pain, dyspnea, and signs of hypotension. It is crucial to consider pulmonary embolism as a potential cause of these symptoms, given the high morbidity and mortality associated with this condition.

Correct Answer: C

Rationale: The nurse should prioritize removing the old dressing and applying a new dressing using sterile technique to minimize the risk of infection during a central venous catheter (CVC) dressing change. This is because the most critical step in preventing infection is maintaining a clean and sterile environment around the CVC insertion site. By using sterile technique, the nurse can reduce the introduction of microorganisms that could potentially lead to infection. Wearing sterile gloves and cleaning the insertion site with an alcohol-based antiseptic solution are important steps as well, but the key priority lies in applying the new dressing using sterile technique to prevent contamination and reduce the risk of infection.

Correct Answer: B

Rationale: The patient's presentation of sudden-onset weakness and sensory loss on one side of the body, along with difficulty speaking and understanding speech that partially resolved within one hour, is consistent with a transient ischemic attack (TIA). TIAs are caused by temporary disruption of blood flow to a part of the brain, leading to transient neurological symptoms. Unlike an ischemic stroke, which results in permanent damage to brain tissue due to prolonged interruption of blood flow, TIAs are transient and resolve within 24 hours. Hemorrhagic strokes and subarachnoid hemorrhages typically present with sudden, severe headaches, and may not improve or resolve quickly as seen in this case.

Correct Answer: C

Rationale: When communicating with a patient from a different cultural background, the nurse should prioritize recognizing and respecting the patient's cultural beliefs and practices. This is essential in providing culturally competent care, fostering trust and rapport with the patient, and ultimately improving health outcomes. By acknowledging and understanding the cultural context of the patient, the nurse can adapt communication strategies, address the patient's needs effectively, and avoid misunderstandings or misinterpretations. Building a culturally sensitive approach can enhance the quality of care and strengthen the therapeutic relationship between the nurse and patient.
