A nurse is using a Doppler ultrasound stethoscope to assess the pedal pulses of a client who has peripheral vascular disease. Which of the following actions should the nurse plan to take?

Exert firm pressure when placing the probe.

Apply the probe to the exterior aspect of the ankle.

Move the probe until a whooshing sound is present.

Hold the probe at a 30° angle to the blood vessel.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Exerting firm pressure when placing the probe (Choice A) is not recommended because it can potentially compress the blood vessels and impede blood flow. This can lead to inaccurate readings and compromise the assessment of the pedal pulses in a client with peripheral vascular disease.

Choice B rationale:

Applying the probe to the exterior aspect of the ankle (Choice B) is not the standard approach for assessing pedal pulses. The pedal pulses are typically assessed on the dorsal (top) and posterior (back) aspects of the foot, as well as the lateral (side) aspects of the ankle. Placing the probe on the exterior aspect of the ankle might not yield accurate results.

Choice C rationale:

Moving the probe until a whooshing sound is present (Choice C) is the correct action when using a Doppler ultrasound stethoscope to assess pedal pulses. The whooshing sound, known as "Doppler sound," indicates the presence of blood flow. The nurse should gently maneuver the probe until this sound is heard, allowing for an accurate assessment of the pulses and blood flow status.

Choice D rationale:

Holding the probe at a 30° angle to the blood vessel (Choice D) is not a standard practice for assessing pedal pulses with a Doppler ultrasound stethoscope. The nurse should place the probe directly over the pulse site and adjust its position until the Doppler sound is detected.

Correct Answer is A

Explanation

Choice A rationale:

Teaching the most crucial content early in the session is an effective strategy to engage learners and ensure that they receive essential information. This approach captures their attention and provides a solid foundation for the rest of the session. It helps establish relevance and interest, keeping the learners engaged throughout the educational program.

Choice B rationale:

Assuming that learners have no prior knowledge of first aid might not be the best approach. Adult learners often come with varying levels of knowledge and experience. It's important to assess the learners' prior knowledge and adjust the content accordingly to avoid redundancy or information that is too basic for them.

Choice C rationale:

Repetition of procedures and techniques is a valuable teaching strategy. Repetition aids in retention and comprehension. Reiterating important points reinforces learning and helps participants remember critical steps in first aid procedures. Avoiding repetition can lead to incomplete understanding and retention.

Choice D rationale:

Dividing the planned program into several sessions held about 1 week apart might not be the most effective strategy for community education. Spacing the sessions too far apart could result in learners forgetting the content or losing interest. It's better to maintain a consistent schedule to ensure continuity and engagement.

Correct Answer is ["50"]

Explanation

Step 1: The total volume of the solution is 100 mL and it needs to be infused over 2 hours.

Step 2: To find the rate in mL/hr, divide the total volume by the total time.

Step 3: Calculation is (100 mL ÷ 2 hr).

Step 4: The IV pump should be set to deliver 50 mL/hr. This is the final answer, rounded to the nearest whole number as required.
