Correct Answer: D

Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.

Correct Answer: C

Rationale: The correct answer is C, Hypotension. Amlodipine is a calcium channel blocker commonly used to treat hypertension. One of the main adverse effects of amlodipine is hypotension, leading to low blood pressure. The nurse should monitor the client for signs of hypotension such as dizziness, lightheadedness, or fainting. Choices A, B, and D are incorrect because constipation, facial flushing, and jaundice are not typically associated with amlodipine administration.

Correct Answer: A

Rationale: The correct answer is A: Asthma. Clients with asthma should avoid Beta2 Blockade agents like propranolol as they can lead to bronchoconstriction, potentially worsening asthma symptoms. Choice B, hypertension, is not a contraindication for propranolol; in fact, it is commonly prescribed for hypertension. Choice C, tachydysrhythmias, is often an indication for propranolol due to its antiarrhythmic properties. Choice D, urolithiasis, does not directly impact the use of propranolol.

Correct Answer: C

Rationale: The correct answer is C. Clients with a history of asthma should avoid amoxicillin due to potential hypersensitivity reactions. Amoxicillin can trigger asthma exacerbations in some individuals. Hypertension (choice A), peptic ulcer disease (choice B), and gastroesophageal reflux disease (choice D) are not contraindications for amoxicillin use, so they do not require the nurse to clarify the medication prescription in this case.

Correct Answer: B

Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.
