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 healthcare professional is assessing postoperative circulation of the lower extremities for a client who had knee surgery. The healthcare professional should test which of the following?

• A. Range of motion
• B. Skin color
• C. Edema
• D. Skin temperature

Correct answer: B

Rationale: Corrected Rationale: Assessing skin color is crucial to evaluate perfusion and circulation postoperatively. Skin color changes can indicate compromised circulation, such as pallor or cyanosis. Edema may suggest fluid retention but is not a direct indicator of circulation status. Range of motion is more related to joint function and mobility, not specifically circulation.

3. The nurse is evaluating client learning about a low-sodium diet. Selection of which meal would indicate to the LPN that this client understands the dietary restrictions?

• A. Tossed salad with low-sodium dressing, bacon, and tomato sandwich.
• B. New England clam chowder, unsalted crackers, fresh fruit salad.
• C. Skim milk, turkey salad, roll, and vanilla ice cream.
• D. Macaroni and cheese, diet Coke, and a slice of cherry pie.

Correct answer: C

Rationale: The correct answer is C: Skim milk, turkey salad, roll, and vanilla ice cream. These items are low in sodium, making it a suitable meal for someone on a low-sodium diet. Skim milk, turkey salad, and vanilla ice cream are naturally low in sodium, while the roll can be selected as a low-sodium option. Choices A, B, and D contain items that are typically high in sodium, such as bacon, clam chowder, crackers, and cheese, making them unsuitable for a low-sodium diet.

4. At the surgical scrub sink, a surgical nurse demonstrated the proper surgical handwashing technique by scrubbing:

• A. With her hands held lower than her elbows
• B. With her hands held higher than her elbows
• C. With her hands in a fist position
• D. With hands placed on her chest

Correct answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

5. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
