A nurse is inserting an NG tube for a client who has a new prescription for enteral feedings. Which of the following actions should the nurse take to verify the placement of the client's tube? (Select all that apply.).

Choice A rationale:

Encouraging the client to ambulate is not appropriate when the client has a high fever of 40°C (104°F). Ambulation requires physical exertion and can potentially worsen the client's condition, especially when they are already experiencing discomfort due to the fever.

Choice B rationale:

Giving the client a cold sponge bath might seem like a logical approach to reduce fever; however, it is not the most effective and safest method. Cold water can cause vasoconstriction and shivering, potentially increasing the body's metabolic demands and raising the temperature further. Additionally, sudden temperature changes can be uncomfortable and may not provide sustained fever reduction.

Choice C rationale:

Administering antipyretics as prescribed is the correct choice. Antipyretic medications, such as acetaminophen or ibuprofen, work to lower fever by acting on the hypothalamus, the body's temperature-regulating center. By reducing fever, the body's metabolic rate and oxygen consumption are decreased, which can help prevent complications associated with high fever, such as dehydration and discomfort.

Choice D rationale:

Providing a cooling fan can offer some comfort, but it might not be sufficient to effectively lower the client's high fever. Fans primarily work by promoting evaporative cooling, which may not be efficient when the body temperature is significantly elevated. Additionally, relying solely on a cooling fan might delay the necessary intervention of administering antipyretic medication.

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.
