What is the initial nursing action for a patient with a chest tube found to have an air leak?

Correct Answer: A

Rationale: When a patient with a chest tube is found to have an air leak, the priority action for the nurse is to check the tube connections. This step helps identify the source of the air leak, which can be caused by loose or disconnected tube connections. Once the source of the leak is identified and addressed, further interventions may be necessary. Replacing or removing and reinserting the chest tube should not be the initial response unless there are specific indications for these actions. Documenting the incident is important but comes after addressing the immediate concern of the air leak.

Correct Answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.

Correct Answer: A

Rationale: Following an escharotomy for burn injuries, patients should be taught to monitor for infection and care for the incision site. Choice A is the correct answer because infection is a common risk after a procedure involving incisions. Choices B, C, and D are incorrect. Restricting fluid intake is not typically advised after an escharotomy; avoiding physical activity may vary depending on the individual's condition and should be guided by healthcare providers; and limiting phosphorus to 1,500 mg/day is not directly related to post-escharotomy care.

Correct Answer: A

Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

Correct Answer: A

Rationale: Corrected Question: During an escharotomy on a patient with a burn injury, the purpose of this procedure is to release pressure and improve circulation in the affected area. This intervention is crucial in severe burns where the formation of eschar (dead tissue) can lead to increased pressure, compromising circulation and potentially causing further tissue damage. Choices B, C, and D are incorrect because escharotomy specifically aims to address pressure and circulation issues in severe burn injuries, rather than removing dead tissue, improving breathing, or preventing infection.
