Nursing Elites

1. Four days following an abdominal aortic aneurysm repair, the client is exhibiting edema of both lower extremities, and pedal pulses are not palpable. Which action should the nurse implement first?

• A. Elevate extremities on pillows
• B. Evaluate edema for pitting
• C. Assess pulses with a vascular Doppler
• D. Wrap the feet with warmed blankets

Correct answer: C

Rationale: In this scenario, the priority action for the nurse is to assess pulses with a vascular Doppler. The absence of palpable pedal pulses following an abdominal aortic aneurysm repair raises concerns about compromised blood flow, which could lead to serious complications like ischemia or thrombosis. Evaluating and confirming the presence or absence of pulses is crucial to guide further interventions. Elevating extremities on pillows (Choice A) may be beneficial for managing edema, but it is not the immediate priority when pulses are not palpable. Evaluating edema for pitting (Choice B) can provide additional information about fluid status but does not address the primary concern of absent pulses. Wrapping the feet with warmed blankets (Choice D) is not appropriate in this situation and may not address the underlying vascular issue.

2. A client with chronic obstructive pulmonary disease (COPD) who is beginning oxygen therapy asks the nurse why the flow rate cannot be increased to more than 2 L/min. The nurse responds that this would be harmful because it could:

• A. Be drying to nasal passages
• B. Decrease the client’s oxygen-based respiratory drive
• C. Increase the risk of pneumonia due to drier air passages
• D. Decrease the client’s carbon dioxide–based respiratory drive

Correct answer: B

Rationale: Increasing the oxygen flow rate beyond 2 L/min for a client with COPD can decrease the client's oxygen-based respiratory drive. In clients with COPD, the natural respiratory drive is based on the level of oxygen instead of carbon dioxide, as seen in healthy individuals. Increasing the oxygen level independently can suppress the drive to breathe, leading to respiratory failure. Choices A, C, and D are incorrect because drying of nasal passages, increased risk of pneumonia due to drier air passages, and decreasing the carbon dioxide-based respiratory drive are not the primary concerns associated with increasing the oxygen flow rate in a client with COPD.

3. The nurse is caring for a client with chronic renal failure who is on a low-potassium diet. Which of the following foods should the client avoid?

• A. Bananas
• B. Potatoes
• C. Rice
• D. Apples

Correct answer: A

Rationale: Bananas are high in potassium content, which can lead to hyperkalemia in clients with chronic renal failure who are on a low-potassium diet. Therefore, it is crucial for these clients to avoid bananas. Potatoes, rice, and apples are lower in potassium compared to bananas and are generally considered safe for consumption in clients with chronic renal failure on a low-potassium diet.

4. A nurse reviews the urinalysis of a client and notes the presence of glucose. Which action should the nurse take?

• A. Document findings and continue to monitor the client.
• B. Contact the provider and recommend a 24-hour urine test.
• C. Review the client’s recent dietary selections.
• D. Perform a capillary artery glucose assessment.

Correct answer: D

Rationale: Glucose normally is not found in the urine. The normal renal threshold for glucose is about 220 mg/dL, which means that a person whose blood glucose is less than 220 mg/dL will not have glucose in the urine. A positive finding for glucose on urinalysis indicates high blood sugar. The most appropriate action would be to perform a capillary artery glucose assessment. The client needs further evaluation for this abnormal result; therefore, documenting and continuing to monitor is not appropriate. Requesting a 24-hour urine test or reviewing the client’s dietary selections will not assist the nurse to make a clinical decision related to this abnormality.

5. A client with type 1 diabetes mellitus has a blood glucose level of 620 mg/dL. After the nurse calls the physician to report the finding and monitors the client closely for:

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

Correct answer: A

Rationale: In the scenario described, a client with a blood glucose level of 620 mg/dL and type 1 diabetes mellitus is at risk of developing metabolic acidosis. In type 1 diabetes, the lack of sufficient circulating insulin leads to an increase in blood glucose levels. As the body cells utilize all available glucose, the breakdown of fats for energy results in the production of ketones, leading to metabolic acidosis. Metabolic alkalosis, respiratory acidosis, and respiratory alkalosis are not typically associated with uncontrolled type 1 diabetes. Metabolic alkalosis is more commonly linked to conditions such as vomiting or excessive diuretic use, while respiratory acidosis and respiratory alkalosis are related to respiratory system imbalances in carbon dioxide levels.
