ATI Pharmacology Proctored Exam 2019

Correct Answer: A

Rationale: To calculate the volume to administer, divide the desired dose by the available concentration. In this case, (80 mg / 10 mg/mL) = 8 mL.

Correct Answer: D

Rationale: When administering Filgrastim, only one dose should be withdrawn from the vial, and the vial should then be discarded. This medication should not be shaken but gently inverted to mix it before withdrawing the appropriate dose. It is important to follow these guidelines to ensure the medication's efficacy and prevent contamination or errors in dosing. Refrigeration is not required for Filgrastim; it should be stored at room temperature until just before administration.

Correct Answer: A

Rationale: The correct action for the nurse to include in the plan of care is to keep the client NPO until the pharyngeal response returns. Tetracaine can affect the gag reflex, so it is important to prevent aspiration by maintaining the client NPO until the pharyngeal response is normal, which typically takes about 1 hour. Monitoring for the return of the gag reflex is crucial to prevent complications from aspiration during the first oral intake after the procedure.

Correct Answer: B

Rationale: The correct answer is B: Alcohol. Clients should avoid alcohol while taking metronidazole due to the risk of a disulfiram-like reaction. This reaction can cause symptoms like flushing, headache, nausea, and vomiting when alcohol is consumed while on metronidazole. Dairy products, leafy green vegetables, and grapefruit juice do not have significant interactions with metronidazole.

Correct Answer: B

Rationale: Diltiazem is a calcium channel blocker that can lead to bradycardia as an adverse effect due to its negative chronotropic and dromotropic effects on the heart. The nurse should monitor the client's heart rate regularly to detect any signs of bradycardia and take appropriate actions if necessary.
