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

To calculate how many milliliters (mL) of diazepam oral solution should be administered, you can use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL)

In this case, the desired dose is 2 mg, and the concentration of the diazepam oral solution is 5 mg/1 mL.

Dose (mL) = 2 mg / 5 mg/mL = 0.4 mL

So, the nurse should administer 0.4 mL of diazepam oral solution with each dose. The correct answer is:

A) 0.4 mL.

A. Request additional information about the caller's relationship to the client. B. Provide a general update about the client's condition over the telephone. C. Refer the family member to the client's provider for the update. D. Encourage the family member to contact the client directly for information.

Correct Answer is C

Explanation

Choice A rationale:

Request additional information about the caller's relationship to the client. Rationale: While understanding the caller's relationship to the client is important for confirming the legitimacy of the request, it doesn't address the core concern of maintaining client confidentiality. Sharing information with individuals solely based on their relationship can still lead to breaches in privacy.

Choice B rationale:

Provide a general update about the client's condition over the telephone. Rationale: Providing a general update over the telephone is not a secure method of maintaining client confidentiality. General updates can inadvertently disclose sensitive information and should only be communicated through secure and private channels.

Choice C rationale:

Refer the family member to the client's provider for the update. Rationale: This choice is the correct answer as it ensures that the family member receives accurate and appropriate information from the authorized source, which is the client's healthcare provider. This approach maintains the confidentiality of the client's medical information and adheres to privacy regulations.

Choice D rationale:

Encourage the family member to contact the client directly for information. Rationale: Encouraging direct contact between the family member and the client for information sharing can potentially compromise the client's privacy. The client might not want their condition disclosed to certain individuals, and it's the responsibility of the healthcare provider to ensure that sensitive information is shared appropriately and securely.
