A nurse is leaving a client's isolation room. Which of the following pieces of personal protective equipment (PPE) should the nurse remove first?

Gloves.

Goggles.

Gown.

Mask.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

When leaving a client's isolation room, the nurse should remove gloves (Choice A) first. Gloves are considered contaminated and can harbor microorganisms. Removing them first helps prevent the spread of potential pathogens to other surfaces or items while removing other personal protective equipment (PPE).

Choice B rationale:

Goggles (Choice B) protect the eyes from splashes and airborne particles. However, they should be removed after gloves. Gloves have a higher potential for contamination due to direct contact with the client and the environment.

Choice C rationale:

Removing the gown (Choice C) should follow the removal of gloves and goggles. The gown provides a barrier against potential contaminants and should be taken off to prevent self-contamination while disrobing from other PPE.

Choice D rationale:

The mask (Choice D) should be removed last. It provides respiratory protection and prevents the nurse from inhaling airborne particles. Keeping the mask on while removing other PPE items helps maintain a barrier against potential exposure to respiratory pathogens.

Correct Answer is C

Explanation

Choice A rationale:

Metabolic acidosis is not the correct acid-base imbalance for the given ABG results. Metabolic acidosis is characterized by a low pH (acidic), low bicarbonate (HCO3) levels, and a compensatory decrease in the PaCO2. In the provided ABG results, the pH is elevated, and both the PaCO2 and HCO3 levels are within normal ranges.

Choice B rationale:

Respiratory acidosis is also not the correct acid-base imbalance for the given ABG results. Respiratory acidosis occurs when there is an elevation in PaCO2 due to inadequate ventilation, leading to an acidic pH. In the provided ABG results, the pH is elevated, and the PaCO2 level is within normal range.

Choice C rationale:

Metabolic alkalosis is the correct acid-base imbalance for the given ABG results. Metabolic alkalosis is characterized by an elevated pH, elevated bicarbonate (HCO3) levels, and a compensatory increase in PaCO2. In this case, the pH is higher than the normal range, the HCO3 level is elevated, and the PaCO2 is also slightly increased as the body attempts to compensate.

Choice D rationale:

Respiratory alkalosis is not the correct answer based on the provided ABG results. Respiratory alkalosis is marked by an elevated pH and a decrease in PaCO2 due to excessive ventilation. In the given ABG results, the pH is elevated, but the PaCO2 is not decreased; it's within the normal range.

A. Exert firm pressure when placing the probe. B. Apply the probe to the exterior aspect of the ankle. C. Move the probe until a whooshing sound is present. D. Hold the probe at a 30° angle to the blood vessel.

Correct Answer is C

Explanation

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.
