A nurse is teaching a client's partner how to administer an optic medication to the client. Which of the following statements by the client's partner indicates an understanding of the teaching?

Choice A Reason:
Visual disturbances is the correct findings. In individuals taking digoxin, visual disturbances such as blurred or yellow-tinted vision can indicate early signs of medication toxicity. This symptom often requires prompt medical attention, as it can precede more severe complications.
Choice B Reason:
Sudden weight gain is not correct. While weight gain can be a symptom of worsening heart failure, it's not typically associated specifically with digoxin toxicity. It's more commonly related to fluid retention in heart failure.
Choice C Reason:
Potassium 4.4 mEq/L is not correct. This potassium level is within the normal range. Digoxin toxicity can be exacerbated by low potassium levels, but a normal potassium level doesn't directly indicate digoxin toxicity.
Choice D Reason:
Insomnia is not a typical early sign of digoxin toxicity. It's more commonly associated with issues like difficulty sleeping rather than being a direct symptom of digoxin toxicity.

Choice A Reason:
Absence of deep-tendon reflexes is correct. The absence or decrease in deep-tendon reflexes can be a sign of magnesium toxicity. Magnesium sulfate, when given in excessive amounts or in the case of accumulation due to impaired renal function, can lead to muscle weakness, hyporeflexia, and in severe cases, loss of deep-tendon reflexes. Discontinuation of magnesium sulfate and administration of calcium gluconate is warranted in severe cases of magnesium toxicity to counteract its effects.
Choice B Reason:
Report of chills is incorrect. Chills are non-specific symptoms and are not typically associated specifically with magnesium toxicity. They are less indicative of a need for calcium gluconate administration in the context of magnesium sulfate infusion.
Choice C Reason:
Decreased level of consciousness is correct. Severe magnesium toxicity can affect the central nervous system, leading to symptoms like confusion, drowsiness, and eventually decreased level of consciousness. In these cases, discontinuation of magnesium sulfate and administration of calcium gluconate is crucial to counteract the effects of excessive magnesium.
Choice D Reason:
Systolic blood pressure of 130 mm Hg is incorrect. A systolic blood pressure of 130 mm Hg, by itself, is not an indicator of magnesium toxicity that necessitates the administration of calcium gluconate. Blood pressure within this range is not typically a cause for concern related to magnesium sulfate administration.
Choice EReason:
Urine output of 80 mL in 4 hours is incorrect. While decreased urine output might indicate potential renal issues or compromised kidney function, it's not a specific indication for the administration of calcium gluconate in the context of magnesium sulfate infusion. It can signal the need for further assessment but is not a direct sign of magnesium toxicity requiring calcium gluconate administration.
