Correct Answer: B

Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

Correct Answer: C

Rationale: The correct answer is to instruct the client to notify the provider if they develop a persistent cough. A persistent cough is a common adverse effect of Captopril and other ACE inhibitors. It is essential for the client to inform their healthcare provider promptly if this side effect occurs, as it may indicate a potentially serious issue that needs medical attention.

Correct Answer: A

Rationale: Seizures are a potential adverse reaction following the administration of local anesthetics like Lidocaine. This adverse effect is important to monitor as it can be life-threatening and requires immediate intervention. It is crucial for the nurse to be vigilant in recognizing any signs of seizure activity to ensure the client's safety and well-being.

Correct Answer: C

Rationale: The correct instruction for a client taking Metoprolol, a medication used to treat hypertension, is to avoid sudden changes in position. Metoprolol can cause orthostatic hypotension, a sudden drop in blood pressure when moving from lying down to standing up, leading to dizziness and falls. By advising the client to change positions slowly, the nurse helps prevent these adverse effects and promotes safety.

Correct Answer: B

Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
