ATI Pharmacology Proctored Exam

1. A client with Schizophrenia is taking Risperidone. Which of the following instructions should the nurse include in the teaching?

A. Increase your intake of snacks to prevent weight loss.
B. Notify the provider if you develop breast enlargement.
C. Be aware of the possibility of mild seizures while taking this medication.
D. Expect an increase in libido when taking this medication.

Correct answer: B

Rationale: The correct instruction the nurse should provide to the client taking Risperidone for Schizophrenia is to notify the provider if they develop breast enlargement. Risperidone can lead to an increase in prolactin levels, causing gynecomastia (breast enlargement) and galactorrhea. Therefore, it is crucial for the client to report these manifestations to the healthcare provider for appropriate management. Choices A, C, and D are incorrect. Increasing snack intake to prevent weight loss is not a specific concern related to Risperidone. Mild seizures are not a common side effect of Risperidone, so this instruction is unnecessary. Risperidone is more likely to cause sexual side effects like decreased libido rather than an increase.

2. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

A. PT
B. aPTT
C. INR
D. Platelet count

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.

3. What are the actions of the drug metformin?

A. Decreases hepatic glucose production and intestinal glucose absorption
B. Increases sensitivity to insulin
C. Short-term sedation
D. Both A and B

Correct answer: D

Rationale: Metformin has dual actions by decreasing hepatic glucose production and intestinal glucose absorption, which helps in reducing blood glucose levels. Additionally, it increases sensitivity to insulin, aiding in its proper utilization within the body. Choice A is correct as metformin acts by decreasing hepatic glucose production and intestinal glucose absorption. Choice B is also correct as metformin increases sensitivity to insulin. Choice C, short-term sedation, is incorrect as metformin is not known for causing sedation. Therefore, the correct answer is D because metformin performs both of these actions.

4. Which of the following conditions are not treated with Barbiturates?

A. Seizures
B. Hypotension
C. Insomnia
D. Anxiety

Correct answer: B

Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.

5. A healthcare professional is reviewing the medical history of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following findings should the healthcare professional report to the provider?

A. Hemoglobin A1C of 7.5%
B. Creatinine level of 1.2 mg/dL
C. BUN level of 18 mg/dL
D. Liver function tests showing AST of 50 units/L

Correct answer: D

Rationale: The correct answer is D. Elevated AST levels in liver function tests should be reported to the provider when a client is prescribed Metformin due to the potential risk of hepatotoxicity associated with the medication. Elevated Hemoglobin A1C (choice A), Creatinine level within normal range (choice B), and BUN level within normal range (choice C) are not directly concerning when initiating Metformin therapy.
