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
"I changed the floor plan of our home to accommodate my father's wheelchair.”.
Choice A rationale:
This statement indicates acceptance of the role change as a caregiver for the aging parents. Making changes to the home to accommodate the father's wheelchair demonstrates the client's willingness to adapt and provide a suitable environment for caregiving.
Choice B rationale:
Feeling stressed out and overwhelmed does not necessarily indicate acceptance of the role change. It may reflect the challenges and emotional burden that come with caregiving but does not necessarily signify acceptance.
Choice C rationale:
Expressing frustration with caregiving does not necessarily indicate acceptance of the role change. It is normal to feel frustrated at times, especially when dealing with chronic illnesses, but acceptance involves embracing the responsibilities that come with the role.
Choice D rationale:
While the statement shows a willingness to learn and adapt to caregiving, it does not explicitly indicate acceptance of the role change. Acceptance involves acknowledging and embracing the new responsibilities and challenges fully.
Correct Answer is C
Explanation
Choice A rationale:
Taking sitz baths can provide comfort but will not directly address the transmission of herpes simplex virus type 2 (HSV-2). It is essential to avoid sexual activity during outbreaks to prevent spreading the infection to a partner.
Choice B rationale:
Cleansing lesions with 1/2 strength peroxide may irritate the affected area and delay healing. The recommended approach is to use gentle soap and water to clean the lesions.
Choice C rationale:
"I will avoid sexual activity until my lesions are healed.”. This statement indicates an understanding of the teaching because HSV-2 is highly contagious during active outbreaks. Avoiding sexual activity during this time is essential to prevent transmitting the virus to a partner.
Choice D rationale:
"I am not contagious once I begin antiviral medication.”. This statement is incorrect as antiviral medications can help manage outbreaks but do not eliminate the risk of transmission entirely. The virus remains contagious until lesions are completely healed.
