RN ATI Capstone Proctored Comprehensive Assessment Form A
1. A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?
- A. PT of 12 seconds
- B. aPTT of 70 seconds
- C. Platelets of 150,000/mm3
- D. INR of 1.5
Correct answer: B
Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.
2. What are the main differences between a stroke caused by ischemia and one caused by hemorrhage?
- A. Blockage in a blood vessel supplying the brain
- B. Bleeding in the brain due to a ruptured aneurysm
- C. Administering thrombolytics if within the treatment window
- D. Avoiding anticoagulants and preparing for surgery
Correct answer: A
Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.
3. A nurse enters a client's room and finds the client pulseless. The client's living will requests no resuscitation be performed, but the provider has not written the prescription. Which of the following actions should the nurse take?
- A. Administer emergency medications without performing CPR
- B. Begin CPR
- C. Call the provider for a do-not-resuscitate (DNR) order
- D. Respect the client's wishes, and do not attempt CPR
Correct answer: B
Rationale: The correct action for the nurse to take in this situation is to begin CPR. In the absence of a written DNR order by the provider, the nurse is ethically and legally obligated to initiate CPR to attempt to save the client's life. Administering emergency medications without CPR (Choice A) may not address the immediate need for life-saving measures. Calling the provider for a DNR order (Choice C) may cause a delay in providing necessary resuscitative measures. Respecting the client's wishes and not attempting CPR (Choice D) goes against the nurse's duty to provide immediate life-saving interventions in the absence of a DNR order.
4. A nurse is assessing a client who is postoperative following a transurethral resection of the prostate (TURP) and notices clots in the client's urinary catheter and decreased urinary output. Which of the following actions should the nurse take?
- A. Administer an antispasmodic
- B. Irrigate the catheter with 0.9% sodium chloride irrigation
- C. Apply gentle manual pressure to the bladder
- D. Clamp the catheter tubing
Correct answer: B
Rationale: In this situation, the nurse should irrigate the catheter with 0.9% sodium chloride irrigation. This action helps clear the clots in the catheter and restore proper urine flow after a TURP. Administering an antispasmodic (Choice A) is not the appropriate action for clots in the catheter and decreased urinary output. Applying gentle manual pressure to the bladder (Choice C) or clamping the catheter tubing (Choice D) could potentially worsen the situation by causing bladder distention or preventing urine drainage.
5. A healthcare provider is providing dietary teaching for a client who has a burn injury and adheres to a vegan diet. The healthcare provider should recommend which of the following foods as the best source of protein to promote wound healing?
- A. One cup of brown rice
- B. One cup of pureed avocado
- C. One cup of lentils
- D. One cup of orange juice
Correct answer: C
Rationale: Lentils are an excellent source of protein, suitable for a vegan diet, and promote wound healing. Brown rice (Choice A) is a carbohydrate-rich food and lacks sufficient protein for wound healing. Pureed avocado (Choice B) is a healthy fat source but low in protein. Orange juice (Choice D) is a source of vitamin C but lacks protein needed for wound healing.
