1. What ECG change is associated with hyperkalemia?

A. Flattened T waves
B. ST depression
C. Prominent U waves
D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

2. What ECG changes are associated with hyperkalemia?

A. Flattened T waves
B. ST depression
C. Prominent U waves
D. Elevated ST segments

Correct answer: B

Rationale: Hyperkalemia is known to cause ST depression on an ECG. Flattened T waves are more commonly seen in hypokalemia. Prominent U waves are associated with hypokalemia rather than hyperkalemia. Elevated ST segments are not typical findings in hyperkalemia.

3. A healthcare provider is assessing a client who reports a possible exposure to HIV. Which of the following findings should the healthcare provider identify as an early manifestation of HIV infection?

A. Stomatitis
B. Fatigue
C. Wasting syndrome
D. Lipodystrophy

Correct answer: B

Rationale: The correct answer is 'B: Fatigue.' Early manifestations of HIV infection often include symptoms like fatigue, fever, and rash, which are typical of viral infections. Stomatitis (choice A) refers to inflammation of the mouth and lips, which can occur in HIV but is not specific to early infection. Wasting syndrome (choice C) and lipodystrophy (choice D) are more commonly associated with later stages of HIV infection rather than early manifestations.

4. A nurse misreads a glucose reading and administers insulin for a blood glucose of 210 instead of 120. What should the nurse monitor the patient for?

A. Monitor for hyperglycemia
B. Monitor for signs of hypoglycemia
C. Administer glucose IV
D. Document the incident

Correct answer: B

Rationale: The correct answer is B: Monitor for signs of hypoglycemia. The nurse should monitor the patient for hypoglycemia due to the administration of excess insulin. Administering insulin for a blood glucose level of 210 instead of 120 can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Option A is incorrect as hyperglycemia is high blood sugar, which is unlikely in this scenario. Option C is incorrect as administering glucose IV would worsen the hypoglycemia. Option D is not the immediate priority; patient safety and monitoring for adverse effects take precedence.

5. What are the manifestations of osteomyelitis?

A. Localized pain, swelling, erythema
B. Elevated white blood cells
C. Elevated calcium levels
D. Low potassium levels

Correct answer: A

Rationale: Osteomyelitis often manifests as localized pain, swelling, and erythema due to infection in the bone. These symptoms are characteristic of inflammation and infection in the bone tissue. Elevated white blood cells (Choice B) may be present as part of the body's immune response to the infection but are not specific manifestations of osteomyelitis. Elevated calcium levels (Choice C) and low potassium levels (Choice D) are not typically associated with osteomyelitis.
