Based on the ABG results: pH 7.33, CO2: 50, HCO3: 22, what acid-base imbalance is present?

Respiratory acidosis

Metabolic acidosis

Metabolic alkalosis

Respiratory alkalosis

Answer and Explanation

The Correct Answer is A

Choice A reason: Respiratory acidosis is indicated by a pH lower than the normal range (7.35-7.45), combined with a CO2 level higher than the normal range (35-45 mmHg). In this scenario, the pH is 7.33, which is slightly acidic, and the CO2 is 50, which is elevated, suggesting that the lungs are not adequately removing CO2.

Choice B reason: Metabolic acidosis is characterized by a low pH and a low HCO3 level. However, in this case, the HCO3 is normal (22-26 mEq/L), ruling out metabolic acidosis.

Choice C reason: Metabolic alkalosis would present with a high pH and a high HCO3 level. Since the pH is low, metabolic alkalosis is not the correct answer.

Choice D reason: Respiratory alkalosis is characterized by a high pH and a low CO2 level. Given that the pH is low and the CO2 is high, respiratory alkalosis is not the condition indicated by these ABG results.

Correct Answer is B

Explanation

Choice A reason: The patient's son may be present for support, but he does not have the authority to sign the consent form unless he is a designated health care proxy and the patient is not competent.

Choice B reason: Since the patient is alert and competent, she has the right and responsibility to provide consent for her own medical procedures.

Choice C reason: A health care proxy is authorized to make decisions on behalf of the patient only if the patient is unable to do so.

Choice D reason: The consent form should be signed by the patient alone if she is competent, regardless of who accompanies her to the facility.

A. Client who has swelling and tenderness around the wound B. Client who has serosanguineous drainage from the wound C. Client who has bromocriptine over the wound D. Client who has urticaria near the wound

Correct Answer is A

Explanation

Choice A reason: Swelling and tenderness around a wound are common signs of infection. The body's inﬂammatory response to the invading bacteria causes these symptoms.

Choice B reason: Serosanguineous drainage, which is composed of both blood and a clear yellow liquid called serum, is typically a normal part of the healing process and not necessarily a sign of infection.

Choice C reason: Bromocriptine is a medication and not a sign of wound infection. This choice seems to be a distractor and does not relate to the clinical signs of a wound infection.

Choice D reason: Urticaria, also known as hives, is a reaction that can be caused by an allergy, stress, or other factors, and is not a direct sign of wound infection.
