Nursing Elites

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 is the priority nursing intervention for a patient admitted with possible acute coronary syndrome?

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

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This intervention is a priority for a patient with possible acute coronary syndrome because nitroglycerin helps vasodilate coronary arteries, increase blood flow to the heart muscle, relieve chest pain, and reduce cardiac workload. Obtaining cardiac enzymes (choice B) is important for diagnosing myocardial infarction but is not the initial priority. Getting IV access (choice C) is essential for medication administration and fluid resuscitation but is not the priority over administering nitroglycerin. Auscultating heart sounds (choice D) is a routine assessment but does not address the immediate need to relieve chest pain and improve blood flow to the heart in acute coronary syndrome.

3. A patient with a new diagnosis of diabetes insipidus is planning care. What should be included in the plan of care?

• A. Avoid alcohol
• B. Increase exercise to reduce stress
• C. Increase fluid intake
• D. Restrict sodium intake

Correct answer: A

Rationale: The correct answer is to avoid alcohol. In diabetes insipidus, excessive urination leads to fluid loss, so it is essential to avoid alcohol which can exacerbate dehydration. Choice B is incorrect as increasing exercise may not directly impact diabetes insipidus. Choice C is also incorrect because although increasing fluid intake may seem intuitive, it is not the primary concern in managing diabetes insipidus. Choice D is not directly related to managing diabetes insipidus; sodium restriction is more relevant in conditions like hypertension or heart failure.

4. What teaching should be provided to a patient following surgical removal of a cataract?

• A. Avoid NSAIDs
• B. Wear dark glasses while outdoors
• C. Creamy white drainage is normal
• D. Reduce phosphorus intake to 700 mg/day

Correct answer: A

Rationale: The correct teaching to provide to a patient following surgical removal of a cataract is to avoid NSAIDs. NSAIDs can increase the risk of bleeding at the surgical site, so it is important to steer clear of them. Choice B, wearing dark glasses while outdoors, may be recommended post-surgery to protect the eyes from bright light, but it is not the priority teaching in this case. Choice C, stating that creamy white drainage is normal, is not accurate as drainage from the eye should be monitored and reported. Choice D, reducing phosphorus intake to 700 mg/day, is unrelated to post-cataract surgery care and is not a necessary teaching point.

5. What teaching should be provided to a patient following an escharotomy for burn injuries?

• A. Monitor for infection
• B. Restrict fluid intake
• C. Avoid physical activity
• D. Limit phosphorus to 1,500 mg/day

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.
