Correct Answer: C

Rationale: Continuous bubbling in the suction-control chamber of the chest tube collection device is an expected finding and indicates that the suction control chamber is connected to suction. It does not necessarily indicate a large air leak, which would be detected in the water-seal chamber. There is no evidence to suggest a pneumothorax based solely on continuous bubbling in the suction-control chamber. Adjusting the suction level by changing the wall regulator setting is not indicated in this situation, as the amount of suction applied is primarily regulated by the water level in the water-seal chamber and not by the vacuum source. Therefore, the most appropriate action in this scenario is for the nurse to take no further action with the collection device.

Correct Answer: D

Rationale: Phototherapy is used to treat high levels of bilirubin among infants, typically evidenced as jaundice. The nurse must position the infant carefully during this procedure to maximize the benefits of the light therapy while protecting the baby. Placing protective eyewear over the baby's eyes without covering the nose is crucial to shield the eyes from the ultraviolet light. Undressing the baby down to a diaper and hat (Choice A) is a standard practice to maximize skin exposure to the phototherapy light. Placing the baby in his mother's arms before turning on the light (Choice B) is not necessary for the preparation of the infant for phototherapy. Positioning the phototherapy light approximately 3 inches above the baby's skin (Choice C) is incorrect as the distance should be as recommended by the healthcare provider based on the manufacturer's instructions.

Correct Answer: D

Rationale: The correct answer is, 'I will call the health care provider right away if I develop a fever.' It is crucial for patients who have undergone a lung transplant to be vigilant about any signs of infection or rejection. A low-grade fever can be an early indicator of such complications, requiring immediate medical attention. While annual follow-up visits are necessary, they are not sufficient for monitoring acute changes in health post-transplant. Stopping prednisone abruptly can lead to rejection and should only be done under healthcare provider guidance. Feeling short of breath with exercise should be reported as it can indicate potential issues. Recognizing and addressing symptoms promptly is key to successful post-transplant care, and in this case, calling the healthcare provider immediately for a fever is the most appropriate action.

Correct Answer: A

Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.

Correct Answer: B

Rationale: The correct order of actions for the nurse in this scenario is to first obtain the oxygen saturation to assess the patient's airway and oxygenation status. Next, checking the patient's pulse rate helps in evaluating circulation. Subsequently, documenting the change in the patient's status is important for maintaining an accurate record of care. Finally, notifying the health care provider is crucial to ensure timely intervention and further management. Choices A, C, and D are incorrect because assessing oxygen saturation should precede checking the pulse rate to address potential physiological causes of confusion. Additionally, documentation should follow patient assessment and notification of the healthcare provider for appropriate record-keeping and communication.
