A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.

Choice A rationale:

A PT (Prothrombin Time) of 12 seconds is not indicative of the effectiveness of heparin therapy for a pulmonary embolism. PT measures the extrinsic pathway of the coagulation cascade, and it is more relevant to monitor in patients on warfarin therapy.

Choice B rationale:

The aPTT (Activated Partial Thromboplastin Time) of 75 seconds is the correct choice as it reflects the effectiveness of unfractionated heparin therapy. Heparin works by inhibiting clotting factors in the intrinsic pathway, and the aPTT is used to monitor heparin's anticoagulant effect. The normal range for aPTT is typically 25-35 seconds.

Choice C rationale:

An INR (International Normalized Ratio) of 1.1 is not the appropriate parameter to assess the effectiveness of heparin therapy. INR is primarily used to monitor the effectiveness of oral anticoagulants like warfarin, not heparin.

Choice D rationale:

The platelet count of 200,000/mm² is not a suitable parameter to evaluate the effectiveness of heparin therapy. Platelet count is important for assessing the risk of bleeding or clotting disorders but does not directly measure the impact of heparin on clotting factors.

Dispose of the client's feces and urine in a special container.

Choice A rationale:

This is the correct choice. Brachytherapy involves the placement of a radiation source in or near the tumor. To minimize radiation exposure to others, the client's bodily fluids (feces and urine) should be considered radioactive and disposed of properly in a designated container.

Choice B rationale:

While limiting the time of visitors can be a good measure to reduce radiation exposure, it is not the priority intervention. The primary concern is proper handling and disposal of radioactive bodily fluids.

Choice C rationale:

Keeping the client's linens in the room until after removal of the radiation source is not the correct choice. Radioactive linens should be handled and laundered separately, following appropriate safety protocols.

Choice D rationale:

Providing one dosimeter badge for staff to share while caring for the client is not adequate. Each staff member involved in direct care should have their dosimeter badge to monitor their individual radiation exposure levels.
