As the head nurse in the OR, how can you improve the effectiveness of clinical alarm systems?

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Regular maintenance and testing ensure alarm systems are functioning properly. 2. Prevents false alarms or missed alerts, improving patient safety. 3. Enhances staff response time to critical situations. 4. Compliance with regulatory requirements for alarm system management. Summary: A: Limiting suppliers doesn't directly affect alarm system effectiveness. B: Inventory management is important but not specific to alarm systems. C: Adherence to manufacturer's recommendations is essential but not sufficient for enhancing effectiveness compared to regular maintenance and testing.

Correct Answer: B

Rationale: The correct answer is B: Convenience. Convenience sampling allows researchers to select any available group of subjects easily accessible to them. This method is often used when specific groups are difficult to reach or when time and resources are limited. Rationale: 1. Purposive sampling (A) involves selecting specific subjects based on predetermined criteria, limiting the flexibility to choose any group. 2. Snow-ball sampling (C) relies on referrals from initial subjects, leading to a biased sample and not allowing for any group selection. 3. Quota sampling (D) involves selecting subjects based on specific characteristics to ensure representation, which also restricts the use of any group. In summary, convenience sampling is the only method that allows for the use of any group of research subjects, making it the correct choice in this scenario.

Correct Answer: B

Rationale: The correct answer is B, "In the operating room." This is because applying the drainage appliance to the stoma immediately after the ileostomy creation in the operating room allows for immediate containment of effluent and reduces the risk of skin irritation or infection. Choice A is incorrect as immediate application is necessary to prevent skin damage. Choice C is incorrect because waiting for the ileostomy to begin functioning can lead to effluent coming into contact with the skin. Choice D is incorrect as self-care procedures should be initiated after application of the drainage appliance to ensure proper stoma care.

Correct Answer: B

Rationale: The correct answer is B: Avoid foods high in vitamin K. Anticoagulants work by preventing blood clotting, and vitamin K is essential for blood clotting. Consuming foods high in vitamin K can interfere with the effectiveness of the anticoagulant medication, leading to potential bleeding risks. Therefore, the nurse should educate the client to avoid such foods to maintain the therapeutic levels of the anticoagulant. Incorrect choices: A: Reporting incidents of diarrhea is important but not directly related to anticoagulant therapy. C: Using a straight razor when shaving can increase the risk of cuts and bleeding, which is contraindicated for a client on anticoagulants. D: Taking aspirin for pain relief is not recommended for a client on anticoagulants due to the increased risk of bleeding.

Correct Answer: B

Rationale: The correct response is to place a saline-soaked sterile dressing on the wound. This step helps to prevent infection, maintain moisture, and protect the exposed tissues. Calling the physician is important, but immediate action to cover the wound is crucial. Taking blood pressure and pulse can wait until the wound is stabilized. Pulling the dehiscence closed can cause further damage and should not be done by the nurse.
