A nurse is caring for a client who has a pulmonary embolism and is receiving therapy with unfractionated heparin. Which of the following laboratory results indicates that the therapy is effective?
PT 12 seconds.
aPTT 75 seconds.
INR 1.1.
Platelets 200,000/mm².
The Correct Answer is B
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.

Correct Answer is A
Explanation
Choice A rationale:
Wearing gloves when changing the cat's litter box is essential during chemotherapy because some chemotherapy drugs can be excreted in bodily fluids, including feces. Protecting against direct contact with potentially harmful substances is crucial to minimize exposure risks.
Choice B rationale:
Taking the temperature once each week is not a relevant precaution during chemotherapy. Monitoring temperature is important, but it should be done more frequently, such as daily, as chemotherapy can cause immunosuppression, increasing the risk of infection.
Choice C rationale:
Being able to attend a concert is not related to precautions during chemotherapy. It is essential for clients undergoing chemotherapy to avoid large gatherings and events where they might be exposed to infections.
Choice D rationale:
Allowing the toothbrush to dry completely between each use is a good hygiene practice but not specifically related to chemotherapy precautions. Proper oral hygiene is essential during chemotherapy, but using a soft toothbrush and regularly replacing it are more relevant considerations.
Correct Answer is A
Explanation
Choice A rationale:
Covering bedside water pitchers after being filled helps reduce the risk of contamination and infection by preventing the entry of airborne pathogens or debris.
Choice B rationale:
Allowing dressings that get wet in the shower to dry out is not an effective infection control strategy. Wet dressings can become a breeding ground for bacteria, and it is important to change wet dressings promptly to minimize the risk of infection.
Choice C rationale:
Used needles should be immediately disposed of in sharps containers, not placed at the nurses' station. Placing used needles in the sharps container promptly helps prevent accidental needlestick injuries and potential transmission of infections.
Choice D rationale:
Drainage bottles should be emptied regularly to prevent overfilling, but they should not be allowed to become full. Regular emptying ensures proper functioning and reduces the risk of spillage or contamination in the client care area.
