1. 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.
2. 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.
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 is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?
- A. I can expect swelling in my hands and on my face.
- B. The amount of protein in my blood is high.
- C. I might have some pain and gas in my stomach from this condition.
- D. I will use a soft bristle toothbrush to prevent bleeding gums.
Correct answer: A
Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.
5. 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.
