ATI Pharmacology

Correct Answer: A

Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr.

Correct Answer: A

Rationale: The correct instruction for a client prescribed furosemide is to take the medication in the morning. Furosemide, a diuretic, is best taken in the morning to prevent nocturia, which is excessive urination at night. Taking it earlier in the day can help reduce disruptions to sleep patterns. Therefore, advising the client to take furosemide in the morning is crucial for optimal therapeutic effects.

Correct Answer: B

Rationale: The correct answer is to take Ferrous sulfate on an empty stomach. This medication is best absorbed when taken 1 hour before or 2 hours after meals. Instructing the client to take it with milk, before bedtime, or with antacids can decrease its absorption and effectiveness.

Correct Answer: A

Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. This medication belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Therefore, it is essential for the nurse to emphasize this potential adverse effect during client teaching to ensure the client is aware of the associated risks.

Correct Answer: A

Rationale: Furosemide is a loop diuretic that can lead to hypokalemia (low potassium levels) due to increased potassium excretion. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with hypokalemia.
