HESI RN CAT Exit Exam Questions
Question 1 of 5
A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client reports difficulty breathing. What action should the nurse take first?
Correct Answer: C
Rationale: The correct answer is C: Check the client's oxygen saturation level. This is the first action the nurse should take to assess the effectiveness of the current oxygen therapy and determine the client's oxygenation status. A: Increasing the oxygen flow rate without assessing the client's oxygen saturation level may lead to potential oxygen toxicity. B: Instructing the client to breathe deeply and cough may not address the underlying issue of hypoxemia. D: Placing the client in a high-Fowler's position may help with breathing but does not address the immediate concern of the client's difficulty breathing. Checking the oxygen saturation level provides crucial information for appropriate interventions.
Question 2 of 5
The nurse is caring for a client who is 2 days post-op following an abdominal hysterectomy. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?
Correct Answer: A
Rationale: The correct action for the nurse to take first is to apply a sterile saline dressing to the wound (Choice A). This is because the client's situation suggests an incisional dehiscence, which is a surgical complication requiring immediate attention to prevent infection and further complications. Applying a sterile saline dressing helps protect the exposed bowel from contamination and dehydration. Notifying the healthcare provider (Choice B) is important, but immediate wound care is the priority to prevent complications. Administering pain medication (Choice C) can wait until after the wound is properly dressed and assessed. Covering the wound with an abdominal binder (Choice D) is not appropriate in this situation as it does not address the urgent need to protect the exposed bowel and prevent infection.
Question 3 of 5
A client with type 1 diabetes mellitus reports feeling shaky and has a blood glucose level of 60 mg/dl. What action should the nurse take?
Correct Answer: A
Rationale: The correct action is to administer 15 grams of carbohydrate because the client is experiencing hypoglycemia with a blood glucose level of 60 mg/dl. Carbohydrates will quickly raise the blood sugar level. Glucagon injection is used for severe hypoglycemia when the client is unconscious. Providing a snack with protein is not the immediate action needed to raise the blood sugar rapidly. Encouraging rest is not effective in treating hypoglycemia.
Question 4 of 5
A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: It prevents the blood from clotting. Warfarin works as an anticoagulant by inhibiting the production of certain clotting factors in the liver. This prevents the formation of blood clots and reduces the risk of conditions like deep vein thrombosis or stroke. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones. Choice C is misleading as it does not actually "thin" the blood but affects its ability to clot. Choice D is unrelated to the mechanism of action of warfarin.
Question 5 of 5
The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
Correct Answer: C
Rationale: Rationale: 1. Heparin primarily affects the intrinsic pathway of coagulation. 2. International Normalized Ratio (INR) is used to monitor the effectiveness of anticoagulation therapy. 3. INR is more specific for monitoring heparin therapy compared to other options. 4. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) are not as accurate for heparin monitoring. 5. Partial Thromboplastin Time (PTT) is used to monitor heparin therapy, but INR is a more precise indicator of heparin's effect.
