Nursing Elites

1. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

2. A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?

• A. Daily weight
• B. Intake and output
• C. Urine specific gravity
• D. Peripheral edema

Correct answer: A

Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.

3. While instructing a male client's wife in the performance of passive range-of-motion exercises to his contracted shoulder, the nurse observes that she is holding his arm above and below the elbow. What nursing action should the LPN/LVN implement?

• A. Acknowledge that she is supporting the arm correctly.
• B. Encourage her to keep the joint covered to maintain warmth.
• C. Reinforce the need to grip directly under the joint for better support.
• D. Instruct her to grip directly over the joint for better motion.

Correct answer: A

Rationale: Acknowledging that the client's wife is supporting the arm correctly is the appropriate nursing action in this scenario. By doing so, the nurse reinforces correct technique and promotes confidence. Choice B is incorrect as the issue is not about maintaining warmth. Choice C is incorrect as gripping directly under the joint is not necessary in this case. Choice D is incorrect as instructing to grip directly over the joint may not provide the best support for passive range-of-motion exercises.

4. The client is being taught how to use a peak flow meter. The nurse explains that this device should be used to:

• A. Determine oxygen saturation
• B. Measure forced expiratory volume
• C. Monitor the atmosphere for the presence of allergens
• D. Provide metered doses for inhaled bronchodilator

Correct answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

5. A client is admitted with infective endocarditis (IE). Which symptom would alert the nurse to a complication of this condition?

• A. Dyspnea
• B. Heart murmur
• C. Macular rash
• D. Hemorrhage

Correct answer: B

Rationale: A new or changed heart murmur is a common sign of valve involvement in infective endocarditis, indicating a complication such as valve damage or regurgitation. Dyspnea is more commonly associated with respiratory or cardiac conditions not directly related to infective endocarditis. A macular rash is not a typical symptom of infective endocarditis, suggesting other conditions like infectious diseases. Hemorrhage is not a direct complication of infective endocarditis but may occur due to factors such as anticoagulant therapy or underlying bleeding disorders.
