A client with a history of deep vein thrombosis (DVT) is receiving a continuous IV heparin infusion. The nurse notes that the client’s activated partial thromboplastin time (aPTT) is 120 seconds. Which action should the nurse take? Reference Range: aPTT [25 to 35 seconds, therapeutic range for heparin 1.5 to 2.5 times baseline, approximately 38 to 88 seconds].

Continue the heparin infusion at the current rate.

Increase the heparin infusion rate by 100 units/hour.

Stop the heparin infusion and notify the provider.

Administer protamine sulfate immediately.

Answer and Explanation

The Correct Answer is C

Choice A reason: Continuing heparin at aPTT 120 seconds is unsafe, as it exceeds the therapeutic range (38–88 seconds), indicating excessive anticoagulation. This risks bleeding, as heparin enhances antithrombin, inhibiting clotting factors. Stopping and notifying the provider prevents hemorrhage, making continuation dangerous for this DVT client.

Choice B reason: Increasing heparin is contraindicated with aPTT 120 seconds, far above therapeutic (38–88 seconds). Excessive anticoagulation from heparin’s antithrombin activation heightens bleeding risk. Stopping the infusion and notifying the provider corrects over-anticoagulation, preventing complications like hematoma, making an increase harmful and inappropriate.

Choice C reason: Stopping heparin and notifying the provider is critical at aPTT 120 seconds, indicating over-anticoagulation. Heparin’s inhibition of clotting factors increases bleeding risk in DVT treatment. Halting infusion prevents hemorrhage, and provider notification ensures dose adjustment or reversal, addressing the pathophysiological risk effectively and promptly.

Choice D reason: Administering protamine sulfate reverses heparin but requires provider order, as aPTT 120 seconds indicates high bleeding risk. Stopping infusion first prevents further anticoagulation, and notifying the provider ensures guided reversal, avoiding premature protamine use, which risks anaphylaxis or thrombosis, making this less immediate.

Correct Answer is B

Explanation

Choice A reason: Observing chest wall shape assesses for abnormalities like barrel chest, not tactile fremitus. Fremitus involves feeling vocal vibrations, increased in pneumonia due to consolidated lung tissue. Visual inspection does not evaluate vibration transmission, making it irrelevant for assessing fremitus in suspected pneumonia.

Choice B reason: Tactile fremitus is assessed by placing the palm on the chest while the client speaks, feeling vibrations through consolidated lung tissue in pneumonia. Fluid-filled alveoli enhance sound transmission, increasing fremitus. This directly evaluates lung pathology, confirming consolidation, critical for diagnosing pneumonia’s extent and severity.

Choice C reason: Using a stethoscope assesses breathing sounds like crackles, not tactile fremitus, which requires palpation of vocal vibrations. While breath sounds aid pneumonia diagnosis, fremitus specifically evaluates consolidation via vibration, making stethoscope use incorrect for this physical assessment technique focused on lung tissue density.

Choice D reason: Compressing tissue for crackling assesses crepitus or subcutaneous emphysema, not fremitus. In pneumonia, fremitus increases due to consolidation, not tissue compression. This method is irrelevant, as fremitus relies on vocal vibration transmission through palpation, making it inappropriate for assessing pneumonia-related lung changes.

A. Discuss checking the time frequently. B. Ask the client why she checks the locks. C. Plan a list of activities to be carried out daily. D. Determine the type and size of the locks.

Correct Answer is C

Explanation

Choice A reason: Discussing time-checking does not address compulsive lock-checking, likely obsessive-compulsive disorder (OCD), driven by serotonin dysregulation causing intrusive fears. Time management is unrelated to compulsions. Planning activities reduces idle time, distracting from OCD behaviors, addressing the neurobiological basis more effectively.

Choice B reason: Asking why the client checks locks may heighten anxiety in OCD, as compulsions arise from irrational fears, not logic, via cortico-striatal-thalamic dysfunction. This may reinforce obsessions. Activity planning distracts from compulsions, offering a therapeutic approach to improve function, making questioning less effective.

Choice C reason: Planning daily activities structures time, reducing compulsive lock-checking in OCD, where obsessive fears disrupt function. Engaging tasks modulate serotonin, distracting from cortico-striatal overactivity, improving behavioral control. This addresses the disorder’s impact, enhancing functionality by minimizing compulsion opportunities, making it the best action.

Choice D reason: Determining lock type is irrelevant to OCD’s compulsive checking, rooted in neurobiological fear responses, not lock characteristics. This does not address serotonin imbalance. Activity planning redirects focus to structured tasks, reducing compulsions, making lock assessment ineffective for managing the client’s behavior.
