ATI Nursing Specialty

Correct Answer: D

Rationale: The correct answer is to instruct the client to use pursed-lip breathing. This technique helps improve breathing efficiency by keeping the airways open during exhalation and reducing air trapping. Restricting fluid intake to less than 2 L/day is not appropriate for a client with COPD, as they need adequate hydration. Using the upper chest for respiration is incorrect as it promotes shallow breathing, which is not ideal for COPD patients. While exercise is beneficial, early-morning hours may not be the best time for clients with COPD due to increased respiratory distress in the morning.

Correct Answer: B

Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

Correct Answer: D

Rationale: Resting with the legs above heart level is important for clients with peripheral arterial disease (PAD) to promote better circulation and reduce leg pain. Applying a heating pad on a low setting can actually worsen symptoms by causing burns or increasing blood flow to the area, which is not recommended for PAD. While keeping the environment warm is generally beneficial, it is not a specific instruction for managing PAD. Antiembolic stockings are typically used for preventing blood clots in hospitalized patients and may not be directly related to managing PAD at home.

Correct Answer: D

Rationale: When assessing a client with COPD, the nurse should expect the client's chest to be barrel-shaped. This shape is a classic characteristic of COPD due to hyperinflation of the lungs. A 'Pigeon' chest shape is associated with pectus carinatum, a deformity of the chest wall. A 'Funnel' chest shape is seen in conditions like pectus excavatum. 'Kyphotic' refers to an exaggerated outward curvature of the thoracic spine. Therefore, the correct answer is 'Barrel' as it is the expected chest shape in clients with COPD.

Correct Answer: A

Rationale: The correct answer is A. The client's statement indicates a need for further teaching because the flowmeter indicates the flow rate of oxygen, not the total amount of oxygen being delivered. Choices B, C, and D demonstrate understanding of safety measures and indications for seeking medical attention in relation to home oxygen therapy, making them appropriate statements.
