What is the therapeutic classification of Furosemide?

Correct Answer: B

Rationale: Furosemide belongs to the therapeutic class of diuretics. Diuretics are medications that promote diuresis, which is the increased production of urine. Furosemide specifically belongs to the loop diuretic class, working by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidney, leading to increased excretion of water and electrolytes. This mechanism makes it a commonly used medication for conditions such as congestive heart failure, edema, and hypertension.

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: D

Rationale: Adenosine is a medication commonly used to treat certain types of irregular heartbeats, such as supraventricular tachycardia. One of the common side effects of adenosine administration is transient asystole or a brief pause in the electrical activity of the heart. This can cause the heart to stop beating momentarily, leading to a drop in blood pressure and a feeling of lightheadedness in the patient. Therefore, in this scenario where the heart monitor shows an immediate abnormality after adenosine administration, the nurse should prepare to administer cardiopulmonary resuscitation and be ready to intervene if the patient's heart rhythm deteriorates further. It is crucial to be proactive and prepared to respond quickly to any adverse effects of the medication to prevent potential harm to the patient. Regular monitoring should also continue to assess the patient's condition and response to treatment.

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: 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.
