The nurse on a surgical unit is caring for a client recovering from recent surgery with the placement of a nasogastric tube to low continuous suction. Which acid-base imbalance is most likely to occur?

A. Type A+: Type A+ blood contains A antigens and Rh factor, which can trigger an immune response in individuals with incompatible blood types. It cannot be universally given in emergencies without typing.
B. Type A/B-: Type AB- contains both A and B antigens. AB is the universal recipient, not donor, and can cause severe transfusion reactions if given to someone with different blood type antibodies.
C. Type O-: O-negative blood is the universal donor for red blood cells because it lacks A, B, and Rh antigens. It minimizes the risk of transfusion reactions and is the safest choice when blood typing cannot be confirmed.
D. Type B+: Type B+ contains B antigens and the Rh factor, making it unsafe for recipients with type A or O blood. It is not suitable for emergency transfusions without matching.

A. The client has pneumonia in the bases: Crackles in the lung bases can suggest pneumonia; however, this finding alone does not confirm a diagnosis. Diagnosis requires clinical correlation with imaging findings such as consolidation or opacities and possibly labs. The physical deformity of the chest (sternal depression) is unrelated to the presence of pneumonia.
B. The client has chronic respiratory disease: While dyspnea and crackles may be seen in chronic respiratory diseases like COPD, the inspection finding of a depressed sternum is not characteristic of these conditions. An illness occurring for two days is also acute and cannot be termed chronic. Documenting a structural deformity based on inspection is more accurate than assuming a chronic disease.
C. The client has a funnel chest: Funnel chest, or pectus excavatum, is a deformity marked by a sunken appearance of the sternum, often more noticeable on inspiration. This is an accurate inspection-based finding that the nurse should document, separate from the respiratory symptoms.
D. The client needs a cough suppressant: A cough suppressant is a potential treatment option for symptomatic relief, but this does not relate to the inspection finding. The nurse’s role at this point is assessment and documentation, not treatment decisions based solely on visual inspection.
