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 D
Explanation
Choice A rationale:
Placing the client in a low Fowler's position with the knees bent (Choice A) can help reduce tension on the abdominal incision, but it is not the priority when evisceration is present. The focus should be on immediate intervention and preparation for surgery.
Choice B rationale:
Covering the client's wound with a sterile saline-soaked dressing (Choice B) is essential to prevent further contamination and maintain moisture in the exposed tissue. This step helps protect the wound until the client can be taken to the operating room.
Choice C rationale:
Notifying the surgeon about the finding (Choice C) is important, but it should not be done before taking more immediate action. Evisceration requires prompt intervention and transfer to surgery, and the surgeon will be involved once the client is ready for the operation.
Choice D rationale:
Preparing the client for transfer to surgery (Choice D) is the correct sequence of steps in this situation. Evisceration is a surgical emergency that requires immediate intervention to prevent complications and infection. The nurse should stabilize the wound with a sterile dressing and then prepare the client for surgery promptly.
Correct Answer is B
Explanation
Choice A rationale:
(Fluticasone) Fluticasone is a corticosteroid inhaler used for the long-term management of asthma symptoms and prevention of asthma attacks. It is not suitable for treating acute asthma
attacks. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
Choice B rationale:
(Albuterol) Albuterol is a short-acting beta-agonist bronchodilator and the preferred medication for relieving acute asthma symptoms and treating asthma attacks. It works by quickly relaxing the airway muscles, making it easier to breathe during an asthma attack. Therefore, this is the correct choice for medications to treat an acute asthma attack.
Choice C rationale:
(Salmeterol) Salmeterol is a long-acting beta-agonist bronchodilator used for the prevention of asthma symptoms but should not be used for treating acute asthma attacks. It has a slower onset of action compared to short-acting beta-agonists like albuterol. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
Choice D rationale:
(Beclomethasone) Beclomethasone is a corticosteroid inhaler used for long-term asthma management and prevention of asthma symptoms but is not appropriate for treating acute asthma attacks. Therefore, this is not the correct choice for medications to treat an acute asthma attack.
