ATI RN Exit Exam Quizlet

Correct Answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with COPD is to encourage the client to increase physical activity. Increased physical activity helps manage COPD symptoms by improving lung function and preventing deconditioning. Placing the client in the Trendelenburg position is not recommended for COPD as it can worsen breathing difficulties. Limiting fluid intake to prevent fluid overload is not typically necessary in COPD unless the client has comorbid conditions that require fluid restriction. Administering high-flow oxygen via mask may be necessary for COPD clients with severe hypoxemia, but it is not the initial action for planning care.

Correct Answer: B

Rationale: Before inserting an indwelling urinary catheter for a female client, the nurse should apply sterile gloves before cleansing the perineal area to prevent infection. Performing perineal care before the procedure is incorrect as it should be done after catheter insertion. Placing the client in a side-lying position is not necessary for this procedure. Lubricating the catheter with petroleum jelly is not recommended as it can damage the catheter; using a water-soluble lubricant is preferred.
