Nursing Elites

1. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

• A. Assess the client's respiratory rate and effort.
• B. Measure the client's oxygen saturation level.
• C. Monitor the client's arterial blood gas levels.
• D. Check the client's blood pressure.

Correct answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

2. While a client is receiving total parenteral nutrition (TPN), which of the following actions should the nurse take?

• A. Monitor the client's blood glucose level every 4 hours.
• B. Change the TPN tubing every 72 hours.
• C. Weigh the client daily.
• D. Change the TPN bag every 24 hours.

Correct answer: D

Rationale: The correct action is to change the TPN bag every 24 hours to reduce the risk of infection. Changing the TPN tubing every 72 hours (Choice B) may increase the risk of contamination. Monitoring the client's blood glucose level every 4 hours (Choice A) is important but not specific to TPN administration. Weighing the client daily (Choice C) is essential for monitoring fluid status but is not directly related to TPN administration.

3. When planning to insert a peripheral IV catheter for an older adult client, which of the following actions should the nurse plan to take?

• A. Insert the catheter at a 45° angle
• B. Place the client's arm in a dependent position
• C. Shave excess hair from the insertion site
• D. Initiate IV therapy in the veins of the hand

Correct answer: B

Rationale: Placing the client's arm in a dependent position is the correct action when inserting a peripheral IV catheter for an older adult client. This position helps veins dilate due to gravity, facilitating easier insertion of the IV catheter. Choice A is incorrect because catheters are typically inserted at a lower angle, around 10-30 degrees. Choice C is unnecessary unless excessive hair impedes the insertion process. Choice D is incorrect as veins in the hand are generally smaller and more prone to complications, making them less ideal for IV therapy in older adults.

4. A healthcare professional is obtaining the blood pressure in a client's lower extremity. Which of the following actions should the healthcare professional take?

• A. Place the bladder of the cuff over the posterior aspect of the thigh
• B. Use a smaller cuff designed for lower extremities
• C. Place the cuff around the client's ankle
• D. Ensure the cuff is positioned above the knee

Correct answer: A

Rationale: When measuring blood pressure in the lower extremity, the bladder of the cuff should be placed over the posterior aspect of the thigh. This positioning ensures an accurate measurement. Placing the cuff around the ankle (Choice C) or above the knee (Choice D) would not provide an accurate blood pressure reading in the lower extremity. Using a smaller cuff designed for lower extremities (Choice B) is not appropriate as the standard cuff size should be used with the bladder placed over the posterior aspect of the thigh.

5. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?

• A. pH below 7.3
• B. Potassium of 5.0
• C. HCT of 60
• D. PaO2 of 79%

Correct answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
