1. A patient experiencing wheezing due to an allergic reaction needs immediate treatment. Which medication should be administered first?

A. Albuterol via nebulizer
B. Cromolyn via nebulizer
C. Aminophylline IV
D. Methylprednisolone IV

Correct answer: A

Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is a rapid-acting bronchodilator that helps relieve wheezing by opening up the airways. During an allergic reaction causing wheezing, prompt relief is crucial, making Albuterol the first-line treatment. Choice B, Cromolyn via nebulizer, is used more for preventing asthma symptoms rather than providing immediate relief. Choice C, Aminophylline IV, is a bronchodilator with a slower onset of action compared to Albuterol. Choice D, Methylprednisolone IV, is a corticosteroid used to reduce inflammation and is not the first-line treatment for acute wheezing in an allergic reaction.

2. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

3. What should be monitored for in a patient with compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and infection
D. Muscle weakness and fatigue

Correct answer: A

Rationale: Correct Answer: A. Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome that indicate inadequate blood flow to the affected area. These symptoms are crucial to monitor as they signify a medical emergency requiring immediate intervention. Choices B, C, and D are incorrect because they do not align with the typical manifestations of compartment syndrome. Localized redness and swelling may be present but are not the primary indicators. Fever and infection are also not specific to compartment syndrome, and muscle weakness and fatigue are not typically prominent symptoms of this condition.

4. What are the signs and symptoms of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and infection
D. Loss of sensation in the affected area

Correct answer: A

Rationale: The signs and symptoms of compartment syndrome include unrelieved pain, pallor, and pulselessness. Unrelieved pain is a key characteristic, indicating tissue ischemia due to increased pressure within a closed anatomic space. Pallor results from compromised blood flow, and pulselessness indicates severe ischemia requiring immediate intervention. Choices B, C, and D are incorrect because localized redness and swelling, fever and infection, and loss of sensation are not specific signs of compartment syndrome. Therefore, the correct answer is A.

5. What ECG changes are expected in a patient with hypokalemia?

A. Flattened T waves
B. Prominent U waves
C. Widened QRS complexes
D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.
