ATI Pharmacology Proctored Exam 2023

Correct Answer: A

Rationale: To determine the flow rate in drops per minute (gtt/min), you can use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, it would be (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Therefore, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min.

Correct Answer: B

Rationale: When the client presses on the nasolacrimal duct while instilling eye drops, it temporarily blocks the lacrimal punctum. This obstruction helps prevent the systemic absorption of the medication by minimizing drainage into the nasolacrimal duct and subsequent systemic circulation. By following this technique, the client can enhance the localized effect of the eye drops and reduce the risk of systemic side effects.

Correct Answer: C

Rationale: The correct answer is C: Delirium. When IV Nitroprusside is infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects.

Correct Answer: C

Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with a full glass of milk (Choice A) is incorrect. Avoiding direct sunlight (Choice B) is not related to erythromycin use. Taking an antacid before the medication (Choice D) can interfere with its absorption.

Correct Answer: A

Rationale: In this situation, where the client's blood pressure is significantly lowered due to Verapamil administration, the nurse should anticipate a prescription for Calcium gluconate. Calcium gluconate is used to reverse severe hypotension caused by Verapamil. It should be given slowly intravenously as it counteracts the vasodilation caused by Verapamil, helping to normalize blood pressure levels.
