Nursing Elites

1. What should be done when continuous bubbling is observed in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Replace the chest tube system
• C. Clamp the chest tube
• D. Continue to monitor the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate action is to tighten the connections of the chest tube system. This may resolve an air leak that is causing the continuous bubbling. Option B, replacing the chest tube system, is not the initial step to take and is considered more invasive. Clamping the chest tube (option C) can lead to complications and should not be done unless instructed by a healthcare provider. Continuing to monitor the chest tube (option D) without taking any corrective action may delay necessary interventions.

2. What ECG changes are expected in a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Widened QRS complexes
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

3. What is the first action a healthcare provider should take for a patient with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the initial priority action for a patient with possible acute coronary syndrome. Nitroglycerin helps dilate blood vessels, reduce chest pain, and improve blood flow to the heart muscle. This helps in relieving symptoms and preventing further damage to the heart. Establishing IV access, auscultating heart sounds, and obtaining cardiac enzymes are important steps in the assessment and management of acute coronary syndrome but are not the first actions to be taken. IV access may be needed for administering medications or fluids, auscultating heart sounds helps in assessing the heart's function, and obtaining cardiac enzymes aids in diagnosing a heart attack.

4. What is an escharotomy and when is it performed?

• A. A surgical incision to release pressure in burn injuries
• B. A procedure to remove dead tissue from wounds
• C. An incision to improve circulation in tight skin after burns
• D. A procedure to remove excess fluid from the chest

Correct answer: A

Rationale: An escharotomy is a surgical incision made to release pressure in a part of the body that has a deep burn and excessive swelling. This procedure is crucial in preventing further damage due to restricted blood flow and compromised circulation. Choice B is incorrect because it describes debridement, which is the removal of dead tissue from wounds. Choice C is incorrect as it does not specifically address the purpose of relieving pressure in burn injuries. Choice D is incorrect as it describes a procedure more related to thoracentesis, which is the removal of excess fluid from the chest, typically the pleural space.

5. A patient is admitted with chest pain, possible acute coronary syndrome. What should the nurse do first?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Obtain cardiac enzymes
• D. Auscultate heart sounds

Correct answer: A

Rationale: In a patient with chest pain, possible acute coronary syndrome, the nurse should administer sublingual nitroglycerin first. Nitroglycerin helps to vasodilate coronary arteries, improving blood flow to the heart, and reducing cardiac workload. This can alleviate chest pain and decrease cardiac tissue damage in acute coronary syndrome. Getting IV access, obtaining cardiac enzymes, and auscultating heart sounds are important steps in the assessment and management of acute coronary syndrome, but administering nitroglycerin to relieve chest pain and improve blood flow takes precedence as it directly addresses the patient's symptoms and aims to prevent further cardiac damage.
