ATI Pharmacology Quizlet

Correct Answer: B

Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.

Correct Answer: D

Rationale: Avoiding reinserting the needle into an IV catheter is crucial to minimizing the risk of catheter embolism. Reinserting the needle can lead to the severing of the catheter's end, potentially causing a catheter embolism, a serious complication. The other options, while important for IV therapy safety, are not directly related to preventing catheter embolism.

Correct Answer: B

Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.

Rationale: Neutropenia is a common adverse effect of paclitaxel due to bone marrow suppression. Clients should be instructed to monitor for signs of infection and report any symptoms such as fever, chills, or sore throat immediately to their healthcare provider.

Correct Answer: A

Rationale: The correct instruction is to remove the prior dose before applying a new one to prevent toxicity. Nitroglycerin ointment can cause adverse effects if accumulated doses are not removed. Rubbing the ointment until it's not visible or covering it with gauze may alter absorption. Applying it to the same area each time can lead to skin irritation or desensitization.
