A nurse is caring for a client in preterm labor who is receiving magnesium sulfate by continuous IV infusion. Which of the following client findings indicates medication toxicity?

Correct Answer: B

Rationale: A urine output of 20 mL per hour is low and indicates renal insufficiency, a sign of magnesium sulfate toxicity. The medication is excreted by the kidneys, so toxicity can occur if renal function declines. Blood glucose of 150 mg/dL is within normal range and not indicative of magnesium sulfate toxicity. A systolic blood pressure of 140 mm Hg is elevated but not specifically related to magnesium sulfate toxicity. A BUN level of 20 mg/dL is also within normal limits and not a sign of medication toxicity.

Correct Answer: C

Rationale: The correct answer is to check the client's circulation. Numbness in the fingers may indicate compromised circulation or nerve damage. By assessing the circulation first, the nurse can ensure that the cast is not too tight, which could be cutting off blood flow. Option A is incorrect because placing the arm in a dependent position may worsen circulation issues. Option B is incorrect as administering pain medication does not address the underlying cause of numbness. Option D is incorrect as applying a warm compress could mask circulation issues and is not the priority in this situation.

Correct Answer: C

Rationale: The correct answer is to administer furosemide. Furosemide is a diuretic commonly used in heart failure to manage fluid retention, helping alleviate symptoms like edema and shortness of breath. Withholding spironolactone, a potassium-sparing diuretic, could lead to electrolyte imbalances. Administering ferrous sulfate is used to treat iron deficiency anemia, not heart failure. Withholding digoxin, a medication used in heart failure to improve heart function, can worsen the client's condition.

Correct Answer: B

Rationale: Corrected Detailed Rationale: A blood glucose level of 250 mg/dL indicates hyperglycemia. Thirst (polydipsia) is a common clinical manifestation associated with hyperglycemia. The body tries to compensate for the high blood sugar by increasing fluid intake. Confusion (choice A) is more commonly associated with hypoglycemia, not hyperglycemia. Diaphoresis (choice C) and shakiness (choice D) are typical manifestations of hypoglycemia, not hyperglycemia. Therefore, the correct answer is increased thirst (polydipsia) in response to the elevated blood glucose level.
