Question 1 of 5
other name of METFORMIN include:
Correct Answer: D
Rationale: Metformin is commonly known by its brand name Glucophage. It is a medication used to treat type 2 diabetes by helping to control blood sugar levels. It works by decreasing glucose production in the liver and improving insulin sensitivity in the body.
Question 2 of 5
Metronidazole is effective in the treatment of ____ (select all that apply)
Correct Answer: A
Rationale: Metronidazole is a versatile antibiotic that is effective in the treatment of various infections caused by anaerobic bacteria and parasites.
Question 3 of 5
A client is prescribed total parenteral nutrition (TPN). Which education should the nurse provide?
Correct Answer: C
Rationale: Total parenteral nutrition (TPN) for long-term use requires a central line because it delivers high-concentration nutrients directly into large veins, like the subclavian, to avoid peripheral vein damage and ensure effective nutrient distribution. Clients can manage TPN at home with proper training, debunking the idea they must stay hospitalized until it's discontinued. It's also administered continuously or cyclically via an infusion pump for precise control, not on a twice-weekly outpatient schedule, which aligns with parenteral nutrition's complexity. The pump ensures steady delivery, critical for metabolic stability, while TPN's comprehensive nutritional support meets all dietary needs intravenously. This central line approach is standard for prolonged therapy, distinguishing it from short-term peripheral options, and supports home management, enhancing quality of life while addressing nutritional deficits effectively.
Question 4 of 5
While assessing a patient who is receiving intravenous digitalis, the nurse recognizes that the drug has a negative chronotropic effect. How would this drug effect be evident in the patient?
Correct Answer: B
Rationale: Digitalis has a negative chronotropic effect, meaning it slows down the heart rate. This can be evident in a patient by observing a decrease in their heart rate. Chronotropy refers to the heart rate or rhythm of the heart. Digitalis works by inhibiting the sodium-potassium pump in the heart muscle cells, leading to an increase in intracellular calcium levels. This results in a decreased heart rate and improved contractility of the heart muscle. Therefore, a decreased heart rate is the expected effect when a patient is receiving intravenous digitalis.
Question 5 of 5
What is pharmacodynamics?
Correct Answer: B
Rationale: Pharmacodynamics refers to the study of the biochemical, physiological, and behavioral effects of drugs on the body and their mechanisms of action. It specifically focuses on the drugs' actions at the receptor site and how these actions lead to specific responses in the body. This includes understanding how drugs interact with target receptors, enzymes, and other molecular targets within the body to produce their effects. Pharmacodynamics also involves studying the relationship between the drug concentration and the magnitude of the response it elicits, as well as factors influencing the variability in individual responses to a drug. In summary, pharmacodynamics is crucial for understanding how drugs work in the body and how they produce their therapeutic or adverse effects.
