Nursing Elites

1. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

• A. Tests the right eye, then tests the left eye, and finally tests both eyes together
• B. Assesses both eyes together, then assesses the right and left eyes separately
• C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
• D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

2. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.

3. Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:

• A. notify the physician of the drainage
• B. change the dressing
• C. reinforce the dressing
• D. apply an abdominal binder

Correct answer: C

Rationale: In the context of a classic cholecystectomy resection, serosanguinous drainage is an expected finding postoperatively due to the nature of the surgery. The appropriate intervention in this situation is to reinforce the dressing. Changing the dressing prematurely can increase the risk of introducing infection. Applying an abdominal binder is not recommended as it can obstruct the visualization of the dressing and the underlying wound, making it difficult to monitor for any complications or changes in drainage. Notifying the physician may be necessary if there are significant changes in the drainage characteristics or other concerning signs, but the immediate action should be to reinforce the dressing to maintain a clean and secure environment for wound healing.

4. A nurse is preparing to assess the dorsalis pedis pulse. The nurse palpates this pulse by placing the fingertips in which location?

• A. Behind the knee
• B. Lateral to the extensor tendon of the big toe
• C. In the groove between the malleolus and the Achilles tendon
• D. Below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines

Correct answer: B

Rationale: The correct location to palpate the dorsalis pedis pulse is lateral to and parallel with the extensor tendon of the big toe. Choices A, C, and D describe the locations for other pulses - popliteal, posterior tibial, and femoral artery respectively. The popliteal pulse is found behind the knee, the posterior tibial pulse is located in the groove between the malleolus and the Achilles tendon, and the femoral artery is situated below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines.

5. The LPN needs to determine the client's respiratory rate. What is the best technique to do this?

• A. Tell the client you need to count their respiratory rate.
• B. Subtly watch the client from across the room when they are doing an activity.
• C. Ask the client to sit still for 30 seconds.
• D. Count respirations while pretending to check the client's pulse.

Correct answer: D

Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.
