Question 1 of 5
What information will the nurse include when teaching the patients about taking beta2-blocking drugs for the treatment of angina?
Correct Answer: D
Rationale: When teaching patients about taking beta2-blocking drugs for the treatment of angina, it is important to include information about monitoring for signs of heart failure. Weight gain can be an early sign of fluid retention, which can indicate heart failure. Instructing patients to alert their healthcare provider if they experience a weight gain of 2 lb or more in 24 hours or 5 lb or more in 1 week can help in early detection and management of potential heart failure. This is crucial for the safety and well-being of the patient.
Question 2 of 5
In assessing a patient before administration of a cardiac glycoside, the nurse knows that which lab result can increase the toxicity of the drug?
Correct Answer: A
Rationale: Low potassium levels, known as hypokalemia, can increase the toxicity of cardiac glycosides such as digoxin. These drugs work by inhibiting the sodium-potassium pump in cardiac cells, leading to increased intracellular sodium levels. When potassium levels are low, it can worsen this effect and lead to increased risk of cardiac dysrhythmias and toxicity from the drug. Potassium levels should be carefully monitored in patients taking cardiac glycosides to prevent complications. A potassium level of 2.8 mEq/L is considered significantly low and would pose an increased risk of toxicity with cardiac glycoside use.
Question 3 of 5
A patient is mowing his lawn on a hot Saturday afternoon. He begins to notice chest pain. What should his first action be?
Correct Answer: B
Rationale: When a patient begins to experience chest pain, especially during physical activity like mowing the lawn on a hot day, the first action should be to stop the activity immediately and sit or lie down. This is because chest pain could be a sign of a serious issue like a heart attack. By stopping the physical activity and resting, the patient can help reduce the workload on the heart and potentially prevent further strain or damage. It is important to take chest pain seriously and seek medical attention promptly.
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 the therapeutic use of metformin?
Correct Answer: D
Rationale: Metformin is a medication commonly used to treat type 2 diabetes by helping to control high blood sugar levels. It works by decreasing the amount of sugar produced by the liver and increasing the body's response to insulin. By aiding in controlling blood glucose levels, metformin helps prevent complications of diabetes such as kidney damage, blindness, nerve problems, and loss of limbs. It does not lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.
