1. A client has a new prescription for Digoxin for heart failure. Which of the following adverse effects should the client be instructed to monitor for and report to the provider?

A. Dry cough
B. Pedal edema
C. Bruising
D. Yellow-tinged vision

Correct answer: D

Rationale: Yellow-tinged vision is a potential adverse effect of digoxin, which may indicate toxicity. It is crucial for the client to report this symptom promptly to the healthcare provider to prevent any further complications. Dry cough is not typically associated with digoxin use. Pedal edema is a common symptom of heart failure, which digoxin is prescribed to manage. Bruising is not a common adverse effect of digoxin.

2. What is the action of Metformin?

A. Decreasing intestinal glucose absorption
B. Increasing sensitivity to insulin
C. Decreasing hepatic glucose production
D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

3. What is the pharmacological action of metformin?

A. Blocks stimulation of beta1 and beta2.
B. Blocks vasoconstriction and aldosterone.
C. Acts at many levels in the CNS to produce an anxiolytic effect.
D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

4. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?

A. These medications work by inhibiting enzymes to prevent HIV replication.
B. These medications work by preventing protein synthesis within the HIV cell.
C. These medications work by weakening the cell wall of the HIV virus.
D. These medications work by blocking HIV entry into cells.

Correct answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.

5. A client with heart failure is prescribed digoxin. Which of the following findings should the nurse identify as an adverse effect of digoxin?

A. Constipation
B. Blurred vision
C. Nausea
D. Headache

Correct answer: B

Rationale: Blurred vision is a common adverse effect of digoxin and can indicate toxicity. Monitoring for visual changes is essential to prevent serious complications in clients taking digoxin.
