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 client is receiving IV moderate sedation with midazolam and has a respiratory rate of 9/min. What should the nurse do?
- A. Place the client in a prone position
- B. Implement positive pressure ventilation
- C. Perform nasopharyngeal suctioning
- D. Administer flumazenil
Correct answer: D
Rationale: The correct answer is D: Administer flumazenil. Flumazenil is the reversal agent for midazolam, a benzodiazepine, and should be administered to counteract respiratory depression. Placing the client in a prone position (choice A) could further compromise their breathing. Implementing positive pressure ventilation (choice B) is not indicated as the first step when dealing with respiratory depression due to sedation. Performing nasopharyngeal suctioning (choice C) is not appropriate in this situation where the client is experiencing respiratory depression due to medication sedation.
3. A client with mild persistent asthma is being taught about montelukast by a nurse. Which statement by the client indicates understanding?
- A. I will use this for asthma attacks.
- B. I should take this before exercise.
- C. This medication will decrease swelling and mucus production.
- D. I can stop this medication after 10 days.
Correct answer: C
Rationale: The correct answer is C: 'This medication will decrease swelling and mucus production.' Montelukast is a leukotriene receptor antagonist that works by reducing swelling and mucus production in the airways, helping to manage asthma symptoms in the long term. Choices A, B, and D are incorrect because montelukast is not used for immediate relief during asthma attacks, pre-exercise prophylaxis, or short-term treatment; instead, it is taken regularly for asthma control.
4. 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.
5. A healthcare provider is reviewing a prescription for doxazosin with a client. Which instruction should the healthcare provider provide?
- A. Decrease caloric intake to reduce weight gain
- B. Increase dietary fiber to prevent constipation
- C. Rise slowly when sitting up
- D. Take this medication each morning
Correct answer: C
Rationale: The correct instruction for a client prescribed with doxazosin is to rise slowly when sitting up. Doxazosin can cause orthostatic hypotension, leading to dizziness upon sudden position changes. Instructing the client to rise slowly helps prevent this side effect. Choices A, B, and D are incorrect because they are not directly related to the potential side effects or administration of doxazosin.
