1. A client with severe preeclampsia is receiving magnesium sulfate intravenously. Which action should the nurse take when toxicity occurs?

• 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: When toxicity from magnesium sulfate occurs, the nurse should administer calcium gluconate IV as it is the antidote for magnesium sulfate toxicity. Positioning the client supine may not address the toxicity issue. Administering dextrose 5% is not the appropriate intervention for magnesium sulfate toxicity. Methylergonovine is used to manage postpartum hemorrhage and is not indicated for magnesium sulfate toxicity.

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 client is prescribed warfarin for anticoagulation. Which of the following laboratory values should the nurse monitor?

• A. PT and INR
• B. Blood glucose levels
• C. Complete blood count (CBC)
• D. Platelet count

Correct answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.

4. A nurse observes an assistive personnel (AP) providing care to a child who is in skeletal traction. Which of the following actions requires intervention?

• A. Providing a high-protein snack
• B. Assisting the child to reposition
• C. Placing weights on the child’s bed
• D. Massaging pressure points

Correct answer: C

Rationale: The correct answer is C. Placing weights on the child's bed can alter the traction, which must remain constant to be effective. This action requires immediate intervention to prevent harm. Providing a high-protein snack (Choice A) is appropriate for the child's nutritional needs. Assisting the child to reposition (Choice B) helps prevent complications such as pressure ulcers. Massaging pressure points (Choice D) can help promote circulation and prevent skin breakdown. However, altering the traction by placing weights on the bed can be detrimental to the child's condition and must be corrected promptly.

5. A nurse is assessing a client who is at risk for falls. Which of the following findings should the nurse recognize as increasing the client's risk of falling?

• A. Normal gait
• B. Recent history of dizziness
• C. 20/20 vision
• D. Takes a multivitamin daily

Correct answer: B

Rationale: The correct answer is B: Recent history of dizziness. A recent history of dizziness significantly increases the risk of falling, as dizziness can impair balance and coordination. Having a normal gait (choice A) and 20/20 vision (choice C) are not factors that directly increase the risk of falling. Taking a multivitamin daily (choice D) does not inherently contribute to an increased risk of falling unless it causes dizziness as a side effect, which is not specified in the question.
