Correct Answer: A

Rationale: Corrected Rationale: If infiltration is suspected, the nurse should immediately stop the dopamine infusion to prevent further damage to the surrounding tissue. Choice A is the correct answer because continuing the infusion can lead to tissue damage and compromise the client's care. Slowing the infusion (Choice B) is not sufficient to prevent harm and may still cause damage. Applying a warm compress (Choice C) or a cold compress (Choice D) is not the recommended action for infiltration; stopping the infusion is crucial to prevent complications.

Correct Answer: B

Rationale: The correct answer is B: 'It can cause bradycardia.' Digoxin can cause bradycardia as one of its side effects. Clients should be educated about this potential effect and instructed to monitor their heart rate before taking the medication. Choice A is incorrect because digoxin is more likely to cause arrhythmias than low blood pressure. Choice C is incorrect as calcium supplements can interfere with the absorption of digoxin. Choice D is incorrect as digoxin has various side effects, and clients should be aware of them.

Correct Answer: A

Rationale: Corrected Rationale: Propranolol, a non-selective beta-blocker, should be avoided in clients with asthma as it can cause bronchoconstriction due to its beta2-blocking effects. Therefore, a client history finding of asthma would require the nurse to clarify this medication prescription. Hypertension, tachydysrhythmias, and urolithiasis are not contraindications for propranolol use, making them incorrect choices. For clients with asthma, a beta1 selective blocker would be preferred to avoid exacerbating bronchoconstriction.

Correct Answer: A

Rationale: A potassium level of 3.0 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity. In this case, the nurse should administer the digoxin without any modifications. Lowering the dose (Choice B) may not be necessary if the potassium level is not critically low. Monitoring serum potassium levels (Choice C) is important but should not delay the administration of digoxin. Discontinuing the medication (Choice D) is not the initial action to take unless the potassium levels become severely low and life-threatening.

Correct Answer: C

Rationale: The correct answer is C: No action is needed at this time. Sedation from opiates commonly decreases as the body adjusts to the medication. It is a positive sign that the sedation has resolved, indicating the client is tolerating the current dosage well. Initiating additional non-pharmacological pain management techniques (Choice A) is unnecessary since the current pain management regimen is effective. Notifying the provider for a dosage adjustment (Choice B) is premature and not indicated when the sedation has resolved. Contacting the provider to request an alternate method of pain management (Choice D) is excessive and not warranted in this situation where the client is no longer sedated and the current pain management plan is effective.
