A nurse is caring for a patient who has acute kidney injury.
The patient’s ABGs are: pH: 7.26, PaCO2: 30 mm Hg, HCO3: 14 mEq/L. Which of the following acid-base imbalances should the nurse identify the patient is experiencing?

Rationale for Choice A: Obtain vital signs

While obtaining vital signs is important in assessing a patient's overall condition, it is not the first priority in a suspected transfusion reaction.

Vital signs can provide valuable information about the severity of the reaction, but they should not delay the immediate action of stopping the transfusion.

Delaying the cessation of the transfusion could allow for further infusion of incompatible blood or allergens, potentially worsening the reaction and leading to more serious complications.

Rationale for Choice B: Notify the registered nurse

Involving other healthcare professionals is crucial in managing transfusion reactions, but it should not precede stopping the transfusion.

The nurse should prioritize stopping the transfusion to prevent further exposure to potential triggers and then promptly notify the registered nurse for further assessment and interventions.

Timely communication with the registered nurse is essential for coordinating care and ensuring appropriate treatment measures are implemented.

Rationale for Choice C: Administer diphenhydramine

Diphenhydramine, an antihistamine, can be used to treat allergic reactions, but it should not be administered as the first response in this scenario.

The priority is to halt the infusion of the blood product that is potentially causing the reaction.

Administering diphenhydramine before stopping the transfusion could mask the symptoms of the reaction, making it more difficult to assess its severity and progression.

Rationale for Choice D: Stop the transfusion

This is the correct and most immediate action to take when a patient develops itching and hives during a blood transfusion.

These symptoms are indicative of a possible allergic or transfusion reaction, and stopping the transfusion is essential to prevent further complications.

It's critical to act quickly to minimize the amount of incompatible blood or allergens that enter the patient's circulation.

By stopping the transfusion, the nurse can potentially prevent the reaction from worsening and safeguard the patient's well- being.

Choice A rationale:

It is not necessary to remind a patient to avoid turning from side to side after femoral artery catheterization. Restricting movement in this way could actually increase the risk of complications such as deep vein thrombosis (DVT).

Early ambulation is generally encouraged to promote circulation and prevent blood clots.

Patients are typically allowed to turn and reposition themselves as needed for comfort, unless there are specific contraindications.

Choice B rationale:

Keeping the patient in a high-Fowler's position for 6 hours is not a standard recommendation following femoral artery catheterization.

The patient's position should be based on their individual needs and comfort level.

In some cases, a slight elevation of the head of the bed may be helpful to promote venous return, but prolonged high-Fowler's positioning is not necessary.

Choice C rationale:

Passive range-of-motion exercises are not typically performed on the affected extremity immediately following femoral artery catheterization.

This is because there is a risk of dislodging the catheter or causing bleeding at the puncture site.

Once the catheter has been removed and the puncture site has healed, gentle range-of-motion exercises may be recommended to help maintain joint mobility.

Choice D rationale:

Checking pedal pulses every 15 minutes is essential to assess for adequate circulation to the lower extremities following femoral artery catheterization.

This is because there is a risk of complications such as thrombosis or embolism, which can compromise blood flow to the legs and feet.

If the pedal pulses are weak or absent, it could indicate a serious problem that requires immediate intervention.
