PN ATI Capstone Proctored Comprehensive Assessment Form A
1. A client is receiving magnesium sulfate for preeclampsia. Which finding indicates magnesium toxicity?
- A. Respiratory rate of 12/min
- B. Diminished deep tendon reflexes
- C. Urine output 40 mL/hr
- D. Systolic blood pressure of 140 mm Hg
Correct answer: B
Rationale: Diminished deep tendon reflexes are a sign of magnesium toxicity. Magnesium sulfate can depress the central nervous system, leading to decreased reflexes. Respiratory rate of 12/min, urine output 40 mL/hr, and systolic blood pressure of 140 mm Hg are not specific findings of magnesium toxicity. Respiratory depression, oliguria, and hypotension are more concerning signs that require immediate attention.
2. 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.
3. A nurse is preparing to administer a measles, mumps, rubella (MMR) immunization to a child. Which is a contraindication for this vaccine?
- A. Recent blood transfusion
- B. Allergy to penicillin
- C. Minor acute illness
- D. Low-grade fever
Correct answer: A
Rationale: The correct answer is A: Recent blood transfusion. A recent blood transfusion can interfere with the effectiveness of the MMR vaccine, making it a contraindication. Choice B, allergy to penicillin, is not a contraindication for the MMR vaccine. Choice C, minor acute illness, is not a contraindication unless the child has a moderate to severe illness. Choice D, low-grade fever, is not a contraindication as long as the child does not have a moderate to severe febrile illness.
4. 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.
5. A client with preeclampsia is receiving magnesium sulfate intravenously. What action should the nurse take if the client develops toxicity?
- A. Position the client supine
- B. Prepare an IV bolus of dextrose 5%
- C. Administer calcium gluconate IV
- D. Administer methylergonovine IM
Correct answer: C
Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote as it helps reverse the effects. Positioning the client supine (Choice A) may not directly address magnesium sulfate toxicity. Administering dextrose 5% (Choice B) is not the correct intervention for magnesium sulfate toxicity. Methylergonovine IM (Choice D) is used to manage postpartum hemorrhage, not magnesium sulfate toxicity.
