ATI Pharmacology Proctored Exam 2019

Correct Answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin.

Correct Answer: D

Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This is important for proper absorption of the medication. Additionally, rotating the patch to different sites each day helps prevent skin irritation and ensures optimal therapeutic effect. Applying the patch to the same site each day can lead to skin irritation or tolerance development. Removing the patch at night is not necessary as the patch is typically worn continuously to provide a consistent level of medication. Covering the patch with a heating pad is contraindicated as it can increase drug absorption, potentially leading to adverse effects.

Correct Answer: C

Rationale: Warfarin interacts with vitamin K, not potassium. The client needs to be cautious with foods high in vitamin K, not potassium.

Correct Answer: A

Rationale: Nitrofurantoin should be taken with food to enhance absorption and reduce gastrointestinal side effects. Taking it with a meal or a snack can help minimize stomach upset. Instructing the client to take the medication with food ensures optimal effectiveness and tolerability of the drug.

Correct Answer: B

Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide.
