HESI RN CAT Exit Exam

Correct Answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

Correct Answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

Correct Answer: A

Rationale: In a 3-year-old boy presenting with dysphagia, drooling, fever, and stridor, the priority intervention should be to place the child in a mist tent. This intervention helps alleviate respiratory distress, providing immediate relief. Options B, C, and D are not as urgent as ensuring the child's airway is managed effectively. Obtaining a sputum culture, preparing for a tracheostomy, and examining the oropharynx can be done after stabilizing the child's respiratory status.

Correct Answer: D

Rationale: Facilitating a meeting for the nurses to identify ways of working together is the best action for the nurse manager. This approach promotes open communication, collaboration, and allows both nurses to express their concerns and perspectives. Option A may not address the underlying issues between the nurses and involving a mental health consultant may not be necessary at this stage. Option B, while listening is important, may not fully resolve the conflict without a structured plan. Option C focuses solely on the senior nurse without involving the new graduate in resolving the situation.

Correct Answer: D

Rationale: Maintaining skeletal pin sites and assessing for infection are critical in skeletal traction care.
