A nurse is assessing a patient following the removal of the patient’s endotracheal tube. Which finding should the nurse report to the provider?

Choice A rationale:

Notifying the facility's security department may be necessary in some cases, but it should not be the nurse's first action. This could escalate the situation and make the patient feel threatened or coerced. It's important to first attempt to de-escalate the situation and understand the patient's reasons for wanting to leave. Involving security prematurely could damage the nurse- patient relationship and make it more difficult to provide care in the future.

Security should be involved if the patient is a danger to themselves or others, or if they are attempting to leave in a way that could cause harm. However, in most cases, it is best to try to resolve the situation through communication and understanding.

Choice B rationale:

Calling the patient's family may be helpful in some cases, but it is not always necessary or appropriate. The nurse should first assess the patient's decision-making capacity and their understanding of the risks of leaving against medical advice. If the patient is capable of making their own decisions, the nurse should respect their autonomy and not involve family members without their consent.

Involving family members without the patient's consent could breach confidentiality and erode trust. It's important to balance the patient's right to privacy with the potential benefits of involving family members.

Choice C rationale:

Insisting that the patient exit the hospital via a wheelchair is not necessary in most cases. If the patient is able to walk and does not pose a safety risk, they should be allowed to leave on their own terms. Requiring a wheelchair could be seen as patronizing or controlling, and it could further upset the patient.

The use of a wheelchair should be based on the patient's individual needs and preferences, not on a blanket policy.

Choice D rationale:

Making sure the patient understands that they are leaving against medical advice is the most important action the nurse can take. This ensures that the patient is aware of the potential risks of leaving the hospital, and it protects the nurse from liability. The nurse should document the patient's decision in the medical record and have the patient sign an Against Medical Advice (AMA) form.

By ensuring informed consent, the nurse respects the patient's autonomy while also fulfilling their professional obligations.

Choice A rationale:

Metabolic alkalosis is characterized by a high pH (above 7.45), high bicarbonate (HCO3-) levels, and normal or low PaCO2. The patient's ABGs show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg), which are not consistent with metabolic alkalosis.

Choice C rationale:

Respiratory alkalosis is characterized by a high pH (above 7.45), low PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low PaCO2, but the pH is low (acidic) and the bicarbonate is low, which are not consistent with respiratory alkalosis.

Choice D rationale:

Respiratory acidosis is characterized by a low pH (below 7.35), high PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low pH, but the PaCO2 is also low, which is not consistent with respiratory acidosis.

Rationale for the correct answer, B:

Metabolic acidosis is characterized by a low pH (below 7.35), low bicarbonate levels, and normal or low PaCO2. The patient's ABGs are consistent with metabolic acidosis because they show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg).

Acute kidney injury is a common cause of metabolic acidosis. The kidneys play a vital role in regulating acid-base balance by excreting acids and reabsorbing bicarbonate. When the kidneys are damaged, they are unable to excrete acids effectively, leading to an accumulation of acids in the blood and a decrease in bicarbonate levels.

Additional Information:

It's important to note that the patient's low PaCO2 is likely a compensatory mechanism for the metabolic acidosis. In response to acidosis, the respiratory system tries to increase ventilation to blow off more carbon dioxide, which helps to raise the pH. However, this compensatory mechanism is often not enough to fully correct the acidosis.
