1. What is the first medication to give to a patient experiencing wheezing due to an allergic reaction?

A. Albuterol via nebulizer
B. Cromolyn 20 mg via nebulizer
C. Methylprednisolone 100 mg IV
D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction due to its rapid action in opening airways. Cromolyn (Choice B) is used for prevention rather than acute treatment. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in allergic reactions.

2. 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.

3. What are the expected findings in a patient experiencing hypokalemia?

A. Flattened T waves on an ECG
B. Elevated ST segments
C. Prominent U waves
D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

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. What is an escharotomy, and why is it performed?

A. To relieve pressure and improve circulation in burn injuries
B. To reduce pain in the affected area
C. To remove necrotic tissue from a wound
D. To remove fluid from a burn wound

Correct answer: A

Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.
