Nursing Elites

1. What precaution should be advised to patients following cataract surgery?

• A. Wear dark glasses while outdoors
• B. Use warm compresses
• C. Avoid NSAIDs
• D. Avoid bright lights

Correct answer: A

Rationale: Patients who have undergone cataract surgery should wear dark glasses when outdoors to shield their eyes from light exposure, which can be uncomfortable or harmful during the recovery period. Using warm compresses (choice B) is not typically recommended after cataract surgery as it's more relevant for certain eye conditions. Avoiding NSAIDs (choice C) is advised to prevent bleeding complications, but it is not directly related to eye protection post-surgery. While avoiding bright lights (choice D) is crucial, wearing dark glasses provides a practical solution to achieve this, making choice A the most appropriate precaution.

2. 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.

3. What signs indicate increased intracranial pressure (IICP)?

• A. Restlessness, irritability, and confusion
• B. Sudden onset of seizures
• C. Bradycardia and altered pupil response
• D. Loss of consciousness

Correct answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.

4. During an escharotomy on a patient with a burn injury, what is the purpose of this procedure?

• A. To release pressure and improve circulation in the affected area
• B. To remove dead tissue from the burn area
• C. To improve breathing by reducing skin tightness
• D. To prevent infection in the burned area

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.

5. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.
