Correct Answer: B

Rationale: Covering the tracheostomy when outside is crucial as it helps prevent dust and other irritants from entering the airway, reducing the risk of complications. Cleaning with alcohol (choice A) can be too harsh for the skin around the tracheostomy site. While replacing the tube weekly (choice C) is important, it is typically done by healthcare providers. Using tap water to clean (choice D) is not recommended as it may introduce contaminants to the tracheostomy site.

Correct Answer: A

Rationale: The main components of a comprehensive discharge plan for a patient with heart failure include advising on appropriate physical activity and exercise to improve cardiovascular health and overall well-being. While fluid restriction and dietary recommendations are important aspects of heart failure management, advising on physical activity and exercise is crucial for improving cardiac function and quality of life post-discharge. Medication management is also essential but focusing on physical activity is particularly relevant for long-term management and preventing readmissions.

Correct Answer: B

Rationale: A footboard is the correct choice to prevent plantar flexion contractures by maintaining proper alignment of the feet. Plantar flexion contractures involve the foot pointing downward, and a footboard helps keep the foot in a neutral position. Choice A, the sheepskin heel pad, is used for pressure ulcer prevention and comfort but does not specifically address plantar flexion contractures. Choice C, the trochanter roll, is used for hip positioning, not foot alignment. Choice D, the abduction pillow, is used to maintain proper positioning of the legs but does not directly address plantar flexion contractures.

Correct Answer: A

Rationale: The correct answer is A because in a postoperative patient, it is crucial to evaluate the effectiveness of the pain interventions that have been implemented. While choices B, C, and D are important aspects of a pain assessment, they do not specifically address the key component of assessing the effectiveness of the interventions applied postoperatively.

Correct Answer: A

Rationale: The correct answer is A: Positioning the patient in a prone position. Prone positioning is a key nursing intervention for patients with acute respiratory distress syndrome (ARDS) as it helps improve oxygenation by allowing better lung ventilation. Choice B, monitoring vital signs and lung sounds, is important but not a key intervention specific to ARDS. Choice C, preparing for mechanical ventilation, may be necessary in severe cases of ARDS but is not a primary nursing intervention. Choice D, administering supplemental oxygen, is a common supportive measure but is not specific to ARDS interventions.
