Nursing Elites

1. A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin (A1C)
• C. Urine output
• D. Serum ketone level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.

2. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

3. A client with hypothyroidism is prescribed levothyroxine. What assessment finding suggests the medication dosage is too high?

• A. Increased sensitivity to cold.
• B. Increased heart rate and palpitations.
• C. Improved energy levels.
• D. Improved tolerance to heat.

Correct answer: B

Rationale: The correct answer is B: Increased heart rate and palpitations. When a client with hypothyroidism is prescribed levothyroxine, these symptoms may indicate that the dosage is too high, causing the client to develop hyperthyroidism. Choices A, C, and D are incorrect. Increased sensitivity to cold is a symptom of hypothyroidism, improved energy levels are an expected outcome of levothyroxine therapy for hypothyroidism, and improved tolerance to heat is not a common sign of levothyroxine overdose.

4. A client is prescribed an inhaled corticosteroid for asthma management. Which instruction should the nurse provide to the client regarding the use of this medication?

• A. Rinse your mouth after using the inhaler
• B. Hold your breath for 5 seconds after inhaling the medication
• C. Use the inhaler during an acute asthma attack
• D. Take the medication only when symptoms occur

Correct answer: A

Rationale: The correct instruction for a client using an inhaled corticosteroid for asthma management is to rinse the mouth after using the inhaler. This helps prevent oral thrush, a common side effect of corticosteroid inhalers. Holding the breath for 5 seconds after inhaling the medication (Choice B) is not necessary for corticosteroid inhalers. Using the inhaler during an acute asthma attack (Choice C) is not the purpose of corticosteroids, which are used for long-term asthma management. Taking the medication only when symptoms occur (Choice D) is not correct as corticosteroids are typically used regularly to control asthma symptoms.

5. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.
