1. What ECG changes are seen with hyperkalemia?

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

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

2. What intervention should the nurse take for a patient experiencing delayed wound healing?

• A. Monitor serum albumin levels
• B. Apply a dry dressing
• C. Administer antibiotics
• D. Change the wound dressing every 8 hours

Correct answer: A

Rationale: Monitoring serum albumin levels is crucial for patients with delayed wound healing. Low albumin levels indicate a lack of protein, which can impair the healing process and increase the risk of infection. By monitoring serum albumin levels, the nurse can assess the patient's nutritional status and make necessary interventions to promote wound healing. Applying a dry dressing (Choice B) may be appropriate depending on the wound characteristics, but it does not address the underlying cause of delayed healing. Administering antibiotics (Choice C) is not the first-line intervention for delayed wound healing unless there is an active infection present. Changing the wound dressing every 8 hours (Choice D) may lead to excessive disruption of the wound bed and hinder the healing process.

3. What should be taught to a patient following cataract surgery?

• A. Avoid NSAIDs
• B. Wear dark glasses when outdoors
• C. Report green or yellow drainage immediately
• D. Itching is normal unless accompanied by pain and nausea

Correct answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.

4. What is the priority intervention for a patient with unstable angina?

• A. Administer nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

5. What is the initial nursing action for a patient with chest pain and acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's urine output
• C. Check cardiac enzymes
• D. Obtain IV access

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.
