A client is taking levothyroxine for hypothyroidism. Which of the following findings should indicate to the healthcare provider that the client is experiencing levothyroxine toxicity?

Correct Answer: C

Rationale: Heat intolerance is a hallmark sign of levothyroxine toxicity. It indicates that the client may be receiving an excessive dose of levothyroxine, leading to hyperthyroid symptoms. This can happen when the dosage is too high, causing the body to have an excess of thyroid hormone. Weight loss is a common symptom of hyperthyroidism but alone does not specifically indicate levothyroxine toxicity. Insomnia can be related to hyperthyroidism but is not a specific sign of levothyroxine toxicity. Dry skin is more commonly associated with hypothyroidism rather than levothyroxine toxicity.

Correct Answer: A

Rationale: When taking alendronate, it is important to take the medication with a full glass of water to prevent esophageal irritation. This helps ensure that the medication reaches the stomach and is properly absorbed. Lying down after taking alendronate can increase the risk of esophageal irritation, which is why it is recommended to stay upright for at least 30 minutes after taking the medication. Taking the medication at bedtime or avoiding dairy products are not specific instructions associated with alendronate administration. Therefore, the correct instruction to include is to take the medication with a full glass of water.

Correct Answer: A

Rationale: The correct answer is A, 'Monitor your blood pressure daily.' When a client is prescribed metoprolol, it is important to monitor blood pressure daily because the medication can cause hypotension, leading to low blood pressure. Regular monitoring allows for the early detection of any potential issues and adjustment of treatment if necessary. Choices B, C, and D are incorrect. Taking metoprolol with food is not necessary, increasing potassium-rich foods is not directly related to metoprolol therapy, and avoiding grapefruit juice is more relevant for certain other medications that interact with grapefruit.

Correct Answer: B

Rationale: The correct answer is to instruct the client to avoid exposure to sunlight. Ciprofloxacin can increase the risk of photosensitivity, making it important to protect the skin from sunlight to prevent skin reactions. This precaution can help prevent skin damage and discomfort in individuals taking ciprofloxacin. Choices A, C, and D are incorrect. Taking ciprofloxacin with milk is not recommended as it may reduce the absorption of the medication. There is no specific instruction to take ciprofloxacin at bedtime. Increasing vitamin K intake is not directly related to ciprofloxacin therapy.

Correct Answer: B

Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.
