ATI Pharmacology Proctored Exam 2024 Questions

Question 1 of 5

A healthcare professional is caring for a client who is receiving heparin therapy. Which of the following laboratory tests should the healthcare professional monitor to evaluate the therapeutic effect of heparin?

Correct Answer: C

Rationale: The correct test to monitor the therapeutic effect of heparin is the activated partial thromboplastin time (aPTT). Heparin's action is to prolong the clotting time, and aPTT reflects this effect. Monitoring aPTT helps ensure that the client is within the therapeutic range to prevent clot formation while minimizing the risk of bleeding complications. PT/INR is used to monitor warfarin therapy, platelet count assesses for potential thrombocytopenia, and WBC count evaluates for signs of infection or inflammation, not the therapeutic effect of heparin.

Question 2 of 5

A client has a prescription for digoxin. The client should be monitored for which of the following findings as an indication of digoxin toxicity?

Correct Answer: A

Rationale: Visual disturbances, such as yellow-tinged vision or seeing halos around lights, are common signs of digoxin toxicity. These symptoms should be reported immediately to healthcare providers for further evaluation and management.

Question 3 of 5

A healthcare professional is educating a client who has a new prescription for Vitamin B12 injections. Which of the following statements should the healthcare professional include?

Correct Answer: B

Rationale: Clients with conditions like pernicious anemia or other causes of vitamin B12 deficiency may require lifelong cyanocobalamin supplementation to prevent deficiency. This is because their bodies are unable to absorb B12 from dietary sources adequately, necessitating ongoing injections to maintain optimal B12 levels.

Question 4 of 5

A client has been on levothyroxine therapy for several months. Which of the following findings indicates a therapeutic response to the medication?

Correct Answer: D

Rationale: A therapeutic response to levothyroxine is indicated by a decrease in the level of TSH. This decrease signifies that the body requires less stimulation to produce thyroid hormone, reflecting a normalization of thyroid function due to the medication's effectiveness.

Question 5 of 5

A client who has been taking prednisone to treat asthma is advised to discontinue the medication. The client should be instructed to reduce the dose gradually to prevent which of the following adverse effects?

Correct Answer: B

Rationale: Abruptly stopping prednisone can result in adrenocortical insufficiency due to suppression of the adrenal glands. Gradually tapering the dose helps the body to adjust and resume its natural cortisol production, preventing adrenal insufficiency.
