PN ATI Capstone Proctored Comprehensive Assessment Form A
1. A nurse is caring for a client who is in preterm labor and is receiving magnesium sulfate via IV infusion. Which of the following findings indicates magnesium toxicity?
- A. Blood glucose of 150 mg/dL
- B. Urine output of 20 mL/hour
- C. Systolic blood pressure of 140 mm Hg
- D. BUN 20 mg/dL
Correct answer: B
Rationale: The correct answer is B. A urine output of 20 mL/hour is a sign of magnesium toxicity because decreased urine output can lead to accumulation of magnesium. Choices A, C, and D are not indicators of magnesium toxicity. Elevated blood glucose, high systolic blood pressure, and normal BUN levels do not specifically point towards magnesium toxicity.
2. A nurse is caring for a client with a sealed radiation implant. Which action should the nurse take?
- A. Remove dirty linens after double-bagging
- B. Wear a dosimeter badge
- C. Limit visitors to 1 hour per day
- D. Ensure family remains 3 feet away from the client
Correct answer: B
Rationale: The correct answer is B: Wear a dosimeter badge. When caring for a client with a sealed radiation implant, the nurse should wear a dosimeter badge to monitor radiation exposure. This badge helps measure the amount of radiation the nurse is exposed to during care. Choice A is incorrect because removing dirty linens after double-bagging is not directly related to managing radiation exposure. Choice C is incorrect as there is no specific time limit on visitors mentioned in the context of a sealed radiation implant. Choice D is incorrect as there is no evidence supporting the need for family members to stay a specific distance away from the client.
3. A charge nurse is teaching a new nurse how to clean surfaces contaminated with blood. Which agent should the charge nurse include in the teaching?
- A. Hydrogen peroxide
- B. Chlorhexidine
- C. Isopropyl alcohol
- D. Chlorine bleach
Correct answer: D
Rationale: Chlorine bleach is the most appropriate agent for disinfecting surfaces contaminated with blood. It is effective in killing a wide range of pathogens, including viruses. Hydrogen peroxide (Choice A) is not as effective as chlorine bleach for bloodborne pathogen disinfection. Chlorhexidine (Choice B) and isopropyl alcohol (Choice C) are more commonly used for skin antisepsis rather than surface disinfection, making them less suitable options in this scenario.
4. A nurse is caring for a client who has preeclampsia and is receiving magnesium sulfate. Which action should the nurse take if the client develops toxicity?
- A. Administer calcium gluconate IV
- B. Increase the magnesium sulfate infusion
- C. Administer IV fluids
- D. Administer hydralazine
Correct answer: A
Rationale: In cases of magnesium sulfate toxicity, administering calcium gluconate IV is crucial as it is the antidote for magnesium sulfate. Calcium gluconate helps reverse the effects of magnesium sulfate, especially when signs of toxicity like respiratory depression or loss of reflexes occur. Increasing the magnesium sulfate infusion would worsen toxicity. Administering IV fluids may be beneficial for hydration but does not address magnesium sulfate toxicity. Hydralazine is used to manage hypertension, not magnesium sulfate toxicity.
5. A client is being taught how to use a PCA pump postoperatively. Which statement indicates understanding?
- A. I should wait until the pain is severe before using the PCA pump.
- B. My family can press the button for me when I'm asleep.
- C. I will press the button when I start to feel pain.
- D. I will only press the button once per hour.
Correct answer: C
Rationale: The correct answer is C because the client should press the PCA pump button when they start to feel pain. This approach helps maintain pain control effectively. Choice A is incorrect because waiting for the pain to become severe before using the PCA pump can lead to inadequate pain management. Choice B is incorrect because only the client should operate the PCA pump to ensure the correct dosage is administered. Choice D is incorrect because the client should press the button as needed when experiencing pain, rather than limiting its use to once per hour.
