Which of the ff nursing interventions is required when caring for a client after cardiac surgery who is at risk for ineffective tissue perfusion?

Correct Answer: C

Rationale: When caring for a client after cardiac surgery who is at risk for ineffective tissue perfusion, it is important to promote optimal blood flow to the tissues. Positioning the lower extremities below the level of the heart helps to facilitate venous return and improve circulation to the extremities. This position helps reduce the workload on the heart and promotes better perfusion to the tissues, ultimately aiding in the prevention of complications related to ineffective tissue perfusion. The other options (A. Restrict fluid intake, B. Ensure that the client avoids prolonged sitting, D. Instruct the client to avoid leg exercises) are not directly related to improving tissue perfusion and may not be appropriate interventions in this situation.

Correct Answer: C

Rationale: Option C, which is to toilet the patient according to his pre-illness schedule, whether or not he feels the urge, is the best intervention by the nurse to help reduce episodes of bowel incontinence in this patient with subarachnoid hemorrhage. This strategy can help establish a routine and promote regular bowel movements, which may reduce the likelihood of bowel incontinence episodes. Asking the patient frequently if he has to have a bowel movement (Option A) may not be effective, as the patient may not always be able to accurately communicate their needs due to the underlying condition. Placing incontinence pads on the patient's bed and chair (Option B) may manage the consequences of incontinence but does not address the root cause. While taking care not to embarrass the patient when incontinent episodes occur (Option D) is important for maintaining the patient's dignity, it does not directly address the issue of reducing bowel incontinence episodes.

Correct Answer: A

Rationale: The medulla oblongata, located in the brainstem, is responsible for controlling essential autonomic functions such as breathing, heart rate, and blood pressure. Specifically, the medulla regulates the rhythm and depth of breathing by sending signals to the respiratory muscles, including the diaphragm and intercostal muscles. In response to changing levels of oxygen and carbon dioxide in the blood, the medulla adjusts the breathing rate to maintain proper oxygenation of the body tissues. Damage to the medulla can result in respiratory failure, highlighting its critical role in controlling breathing.

Correct Answer: C

Rationale: Elevating the head of the bed is an important intervention to help prevent complications in patients with impaired respiratory function. By elevating the head of the bed, gravity assists in improving lung expansion and ventilation, making breathing easier for the patient. This position promotes better airflow and can help reduce the risk of respiratory complications such as aspiration. It is a non-invasive and simple intervention that can be easily implemented in a home care setting to support the patient's respiratory function and overall well-being. Antibiotics, bedrest, and scheduled suctioning are not directly related to improving respiratory function in this context.
