A nurse is reviewing a client's arterial blood gas (ABG) results. Which of the following ABG results should the nurse anticipate when caring for a client with acidosis?

pH 7.42, PaCO2 48 mm HG, HCO3 25 mEq/L

pH 7.28, PaCO2 63 mm HG, HCO3 22 mEq/L

pH 7.49, PaCO2 30 mm Hg, HCO3 35 mEq/L

pH 7.36; PaCO2 42 mm Hg, HCO3 26 mEq/L

Answer and Explanation

The Correct Answer is B

A.   This result shows a slightly elevated PaCO2, which could suggest respiratory compensation for a metabolic alkalosis, not acidosis, as the pH is within the normal range.
B.   This result indicates both a low pH and an elevated PaCO2, which are consistent with respiratory acidosis. The low HCO3 also suggests a metabolic acidosis component, making it the best match for a client with acidosis.

C.   The elevated pH indicates alkalosis. The low PaCO2 and high HCO3 further suggest a primary respiratory alkalosis with metabolic compensation.
D.   These values are within normal limits, indicating neither acidosis nor alkalosis.

Correct Answer is D

Explanation

A. "I get chest pain from time to time, but it usually resolves with rest.": While chest pain (angina) can occur with aortic stenosis, it is not as specific as the symptom described in option D. Angina could be related to various other cardiac conditions, including coronary artery disease.

B. "Sometimes when I'm resting, I can feel my heart skip a beat.": Palpitations or feeling like the heart skips a beat are common in many cardiac arrhythmias but are not specifically indicative of aortic stenosis.

C. "My feet and ankles have gotten very puffy the last few weeks.": Edema (puffy feet and ankles) is more commonly associated with right-sided heart failure or other conditions like chronic venous insufficiency, not specifically aortic stenosis.

D. "Whenever I do any form of exercise, I get very short of breath.": Dyspnea on exertion is a classic symptom of aortic stenosis. It occurs because the narrowed aortic valve obstructs blood flow from the left ventricle to the aorta, reducing cardiac output and causing exertional symptoms.

A. Allergic rhinitis B. Cough C. Hypotension D. Wheezing E. Urticaria

Correct Answer is ["A","B","C","D","E"]

Explanation

A. Allergic rhinitis: This is a common manifestation of a type I hypersensitivity reaction, often involving nasal congestion, sneezing, and itching.

B. Cough: While a cough can occur, it is not as specific or common in the context of systemic type I hypersensitivity reactions as the other options.

C. Hypotension: Hypotension can occur due to vasodilation and increased vascular permeability, which are hallmarks of systemic anaphylaxis.

D. Wheezing: Wheezing results from bronchoconstriction, a common feature in systemic type I hypersensitivity reactions, such as anaphylaxis.

E. Urticaria: Urticaria (hives) is a common skin manifestation of a type I hypersensitivity reaction, characterized by itchy, raised welts on the skin.
