Nursing Elites

1. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:

• A. Refrigerates the collected specimen
• B. Collects the specimen in a sterile container
• C. Delays the collection of the specimen
• D. Uses a non-contaminated collection container

Correct answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.

2. A client with rheumatoid arthritis is prescribed methotrexate. What information should the LPN include when teaching the client about this medication?

• A. Avoid exposure to sunlight.
• B. Take the medication with food.
• C. Increase fluid intake while on this medication.
• D. Report any signs of infection to the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: 'Report any signs of infection to the healthcare provider immediately.' Methotrexate is an immunosuppressant medication commonly used to treat rheumatoid arthritis. It can lower the immune system's ability to fight infections, making it crucial for clients to promptly report any signs of infection to prevent serious complications. Choices A, B, and C are incorrect because avoiding sunlight, taking the medication with food, and increasing fluid intake are not specific to methotrexate therapy and are not primary concerns associated with this medication.

3. 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.

4. A client with a history of heart failure presents with increased shortness of breath and swelling in the legs. What is the most important assessment for the LPN/LVN to perform?

• A. Monitor the client's oxygen saturation level.
• B. Assess the client's apical pulse.
• C. Check for jugular vein distention.
• D. Measure the client's urine output.

Correct answer: C

Rationale: Checking for jugular vein distention is crucial in assessing fluid overload in clients with heart failure. Jugular vein distention indicates increased central venous pressure, which can be a sign of worsening heart failure. Monitoring oxygen saturation (Choice A) is important but may not provide immediate information on fluid status. Assessing the apical pulse (Choice B) is relevant for monitoring heart rate but may not directly indicate fluid overload. Measuring urine output (Choice D) is essential for assessing renal function and fluid balance but does not provide immediate information on fluid overload in this scenario.

5. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?

• A. 107 mL/hr
• B. 75 mL/hr
• C. 90 mL/hr
• D. 60 mL/hr

Correct answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL ÷ 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
