A dopamine infusion was started in a patient's antecubital vein during resuscitation for profound hypotension, but the electronic infusion device is now sounding an alert for an occlusion. What is the most important immediate concern for the nurse?

Correct Answer: B

Rationale: Dopamine is a vasopressor used to treat hypotension by increasing cardiac output and systemic vascular resistance. An interruption in the infusion can lead to a sudden drop in blood pressure, which is life-threatening in a patient already experiencing profound hypotension. The nurse's immediate concern should be to ensure the infusion is restarted promptly. While infiltration and extravasation (A) are concerns, they are secondary to maintaining the infusion. Reporting the device (C) is not the priority, and hypertension (D) is unlikely due to an occlusion alarm.

Correct Answer: B

Rationale: In this context, a liquid preparation of vegetable drugs prepared by percolation and containing alcohol is known as a fluid extract. Fluid extracts are concentrated herbal extracts that are typically made by percolating a solvent, such as alcohol, through the plant material to extract its active constituents. This process results in a liquid extract that contains the medicinal properties of the plant. Fluid extracts are commonly used in herbal medicine due to their potency and ability to preserve the therapeutic compounds of the plant.

Correct Answer: A

Rationale: Propranolol belongs to the class of drugs known as beta blockers. Beta blockers work by blocking the effects of adrenaline on beta receptors in the body, resulting in decreased heart rate, blood pressure, and cardiac output. Propranolol is commonly used to treat conditions such as hypertension, angina, and certain cardiac arrhythmias. It is specifically a non-selective beta blocker, meaning it blocks both beta-1 and beta-2 receptors.

Correct Answer: D

Rationale: Infliximab is a biologic medication used to treat autoimmune conditions like rheumatoid arthritis and Crohn's disease. Common side effects include fatigue and headache, which are generally mild but can affect the patient's quality of life. Chest pain is a less common but serious side effect that may indicate cardiovascular complications or infusion reactions. Nausea is not typically associated with infliximab. Nurses should educate patients about these potential side effects and advise them to report any severe or persistent symptoms, such as chest pain, immediately.

Correct Answer: C

Rationale: Fluorouracil, an antimetabolite chemotherapy drug, can cause myelosuppression, leading to a decrease in platelets (thrombocytopenia). Bleeding gums is a sign of low platelet counts and potential bleeding risk, which can be life-threatening if not addressed promptly. Nausea, decreased appetite, and constipation are common side effects of chemotherapy but are not as urgent as bleeding gums, which indicates a potential hematologic emergency. The nurse should report this symptom immediately to the healthcare provider for further evaluation and intervention, such as platelet transfusion or dose adjustment.

Correct Answer: C

Rationale: The most concerning assessment finding for a patient receiving digoxin is a low serum potassium level (Option C). Hypokalemia increases the risk of digoxin toxicity, as low potassium levels enhance the effect of digoxin on the myocardium, leading to an increased risk of serious dysrhythmias. It is important to address and correct hypokalemia promptly to prevent potential adverse effects of digoxin. An apical heart rate of 58 beats/min (Option A) could be an expected finding for a patient on digoxin, and ankle edema +1 bilaterally (Option B) is a common symptom of heart failure. A serum digoxin level of 0.8 ng/mL (Option D) is within the therapeutic range for digoxin and is not concerning in the absence of other symptoms. Therefore, managing the low serum potassium level is of utmost

Correct Answer: A

Rationale: Sedatives are a type of drug that depresses the central nervous system and can induce a state of calmness and relaxation. In higher doses, sedatives can lead to stupor, which is a state of near-unconsciousness or insensibility. Stupor is often characterized by a marked decrease in alertness and responsiveness. Examples of sedatives include benzodiazepines, such as Valium and Xanax, as well as non-benzodiazepine sedatives like Ambien and Lunesta.

Correct Answer: A

Rationale: The drug classes considered first-line treatments for heart failure include Angiotensin-converting enzyme (ACE) inhibitors, Angiotensin II receptor blockers (ARBs), and Beta blockers.
