Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Stop exercising if pain occurs.' In peripheral arterial disease (PAD), it is crucial to avoid exercising to the point of pain as this may worsen the condition and lead to complications. Exercising to the point of pain can result in inadequate blood flow to the extremities, causing further damage. By stopping exercise if pain occurs, the client can prevent exacerbating their condition. Choices A, C, and D are incorrect because exercising to the point of pain, limiting exercise to once per week, and avoiding walking altogether are not recommended strategies for managing PAD and could potentially harm the client.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with hypertension involve monitoring blood pressure and educating the patient about lifestyle changes. These interventions help in managing hypertension by keeping track of the patient's blood pressure readings and empowering them with knowledge to make lifestyle modifications such as adopting a healthy diet, regular exercise, stress management, and avoiding smoking and excessive alcohol consumption. Administering antihypertensive medications (choice B) is typically done by a healthcare provider rather than a nurse. While regular monitoring of blood pressure (choice C) is important, administering diuretics is a specific medical intervention that should be prescribed by a healthcare provider. Monitoring blood glucose (choice D) is more relevant for patients with diabetes rather than hypertension.

Correct Answer: B

Rationale: Constant bubbling in the water seal chamber indicates an air leak, which should be reported to the provider. This finding suggests that the chest tube system is not functioning properly, leading to potential complications such as pneumothorax. Drainage of 75 mL in the first hour after surgery is within the expected range for a chest tube. Tidaling in the water seal chamber is a normal fluctuation and indicates proper functioning of the system. Client report of pain at the chest tube insertion site is expected after surgery and can be managed with appropriate pain management measures.

Correct Answer: B

Rationale: Monitoring cardiac status is crucial during the acute phase of Kawasaki disease because of the potential for coronary artery complications. Acetaminophen may be used for fever management but is not the priority intervention. Antibiotics are not indicated as Kawasaki disease is not caused by a bacterial infection. Providing stimulation in the playroom is important for the child's emotional well-being but does not address the immediate physiological concern of cardiac monitoring.

Correct Answer: B

Rationale: The correct initial action when a client with a tracheostomy exhibits respiratory distress is to suction the tracheostomy. This helps to clear secretions and improve the client's ability to breathe. Notifying the provider (choice A) can cause a delay in immediate intervention. Administering a bronchodilator (choice C) may be necessary but is not the priority in this situation. Increasing the oxygen flow rate (choice D) can be helpful but should come after addressing the immediate need for suctioning to clear the airway.
