A patient has been started on therapy of a continuous infusion of lidocaine after receiving a loading dose of the drug. The nurse will monitor the patient for which adverse effect?

Correct Answer: D

Rationale: Lidocaine is a local anesthetic that can have systemic effects if levels become toxic. Continuous infusion of lidocaine can lead to lidocaine toxicity, which can manifest as adverse effects including convulsions, altered mental status, confusion, seizures, and cardiac arrhythmias. Monitoring for signs of lidocaine toxicity, such as convulsions, is crucial when a patient is receiving continuous lidocaine infusion. It is important for the nurse to closely monitor the patient's neurological status and vital signs to promptly recognize and manage any adverse effects.

Correct Answer: D

Rationale: When a patient is experiencing digoxin toxicity, severe sinus bradycardia that does not respond to cardiac pacing is a clinical situation that would necessitate the use of digoxin-specific antibody fragments (Digibind). This intervention is required to counteract the toxic effects of digoxin on the heart, especially in cases of severe bradycardia that can compromise cardiac output and lead to serious consequences. In this scenario, Digibind works by binding to digoxin molecules, thereby neutralizing their effects and helping to restore normal cardiac function.

Correct Answer: A

Rationale: A. Assess lung sounds, Pulse, and Blood pressure before administering: It is important to assess the patient's baseline lung sounds, pulse rate, and blood pressure before administering Albuterol to monitor for any changes that may occur after administration. This is crucial in determining the effectiveness of the medication and detecting any potential side effects.

Correct Answer: C

Rationale: When administering Penicillin, one of the adverse effects to watch out for as a sign of an acute allergic reaction is the development of a skin rash or hives. This reaction may indicate an allergic response to the medication. It is important for the nurse to monitor the patient closely for any signs of an allergic reaction, including skin changes, and to act promptly if such symptoms arise. An acute allergic reaction can progress to a severe life-threatening condition known as anaphylaxis, so prompt recognition and intervention are critical in such cases.

Correct Answer: A

Rationale: Spironolactone is a potassium-sparing diuretic, which means it inhibits sodium reabsorption in the kidneys, while saving potassium and hydrogen ions. It accomplishes this by acting as an aldosterone antagonist, blocking the action of aldosterone. Aldosterone is a hormone that normally promotes sodium reabsorption in the kidneys and leads to potassium and hydrogen ion excretion. By inhibiting aldosterone, spironolactone promotes sodium excretion while conserving potassium and hydrogen ions.
