A nurse is caring for a client prescribed digoxin. Which of the following should alert the nurse to possible digitalis toxicity?

Correct Answer: A

Rationale: Corrected Rationale: Digitalis toxicity is a serious complication of digoxin therapy, particularly in older adults. Early symptoms include anorexia, nausea, and generalized weakness. Anorexia and weakness are common indicators of digitalis toxicity. Hyperactivity, hunger, tachycardia, increased urination, polyphagia, and polydipsia are not typical signs of digitalis toxicity. Monitoring for anorexia and weakness can help detect toxicity early and prevent life-threatening arrhythmias.

Correct Answer: A

Rationale: Naloxone is the correct answer. Naloxone is the antidote for opioid overdose, including hydromorphone. Opioids can cause respiratory depression, and a significant decrease in respiratory rate from 16 to 6 breaths per minute indicates respiratory compromise. Naloxone should be administered promptly to reverse the effects of the opioid and restore normal respiratory function. Flumazenil (Choice B) is used to reverse the effects of benzodiazepines, not opioids. Activated charcoal (Choice C) is used for gastrointestinal decontamination in cases of overdose with certain substances, but it is not the appropriate intervention for opioid-induced respiratory depression. Aluminum hydroxide (Choice D) is an antacid and has no role in managing opioid overdose or respiratory depression.

Correct Answer: A

Rationale: The correct answer is A: 'Notify your provider if you experience restlessness or spasms of the face or neck.' Metoclopramide can cause extrapyramidal symptoms, such as restlessness and muscle spasms, particularly of the face and neck. These symptoms should be reported to the provider immediately. Choice B is incorrect because metoclopramide is not meant to be taken only when feeling nauseous; it is used to treat nausea and vomiting. Choice C is incorrect because it is important to stay hydrated while taking metoclopramide. Choice D is incorrect because metoclopramide is usually taken before meals to improve gastric emptying, not necessarily on an empty stomach.

Correct Answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through urine, causing hypokalemia. Hyperkalemia (choice A) is not a side effect of furosemide. Hyponatremia (choice C) and hypernatremia (choice D) are related to sodium levels rather than potassium, and they are not typically associated with furosemide use.

Correct Answer: C

Rationale: The correct answer is to advise the client to avoid potassium supplements. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Adding potassium supplements on top of this medication can lead to hyperkalemia, an elevated level of potassium in the blood, which can be dangerous. Choices A, B, and D are incorrect because increasing potassium-rich foods, limiting sodium intake, and increasing protein intake are not specifically related to the dietary considerations when taking spironolactone.
