ATI Detailed Answer Key Medical Surgical

1. The healthcare provider is caring for a postoperative client who has a chest tube connected to suction and a water seal drainage system. Which of the following indicates to the healthcare provider that the chest tube is functioning properly?

Correct answer: A

Rationale: Fluctuation of the fluid level within the water seal chamber indicates proper functioning of the chest tube. This fluctuation reflects the normal ebb and flow of air and fluid in the pleural space, demonstrating that the system is maintaining the appropriate pressure. Continuous bubbling in the water seal chamber may indicate an air leak, absence of fluid in the drainage tubing suggests a blockage, and equal amounts of fluid drainage in each collection chamber are not expected in this system.

2. A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?

Correct answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.

3. A client with chronic obstructive pulmonary disease is being taught by a nurse. Which nutritional information should the nurse include in the teaching? (SATA)

Correct answer: D

Rationale: In chronic obstructive pulmonary disease, it's important to consider the impact of nutrition on respiratory function. Eating high-fiber foods can lead to increased gas production, causing abdominal bloating and potentially worsening shortness of breath. Therefore, it is advisable for clients with COPD to avoid high-fiber foods to prevent these issues. Resting before meals can help manage dyspnea, and having smaller, more frequent meals can prevent bloating. Increasing calorie and protein intake is essential to prevent malnourishment in COPD patients. Additionally, limiting carbohydrate intake is crucial as it can increase carbon dioxide production, leading to a higher risk of acidosis in these individuals.

4. A client with tuberculosis (TB) is taking isoniazid (INH). Which instruction is most important for the nurse to include?

Correct answer: D

Rationale: Regular monitoring of liver function tests is crucial for clients taking isoniazid (INH) due to the potential risk of hepatotoxicity. Isoniazid can cause liver damage, and early detection through routine liver function tests can help prevent severe complications.

5. When prioritizing client care after receiving change-of-shift report, which of the following clients should the nurse plan to see first?

Correct answer: D

Rationale: When a client expresses being short of breath, it may indicate a serious condition requiring immediate attention to ensure adequate oxygenation. This client should be seen first to assess the severity of the situation and initiate appropriate interventions. The other options, such as awaiting transport for an x-ray, having a prescription for discharge, or receiving oral pain medication 30 minutes ago, do not present immediate life-threatening concerns compared to a client experiencing shortness of breath.
