Question 1 of 5
A patient with a history of pancreatitis and cirrhosis is also being treated for hypertension. Which drug will most likely be ordered for this patient?
Correct Answer: D
Rationale: Given the patient's medical history of pancreatitis and cirrhosis, both conditions can affect the functioning of the liver and potentially interact with medications that are metabolized by the liver. Captopril is an angiotensin-converting enzyme (ACE) inhibitor, which is often a preferred choice for patients with liver disease as it has minimal hepatic metabolism. This decreased reliance on hepatic metabolism makes captopril a safer choice for this patient compared to other antihypertensive medications that may cause liver-related complications. Additionally, ACE inhibitors like captopril are commonly used in patients with hypertension to help reduce blood pressure and protect against further complications related to cardiovascular health.
Question 2 of 5
When teaching a patient who has a new prescription for transdermal nitroglycerin patches, the nurse tells the patient that these patches are most appropriately used for which situation?
Correct Answer: C
Rationale: Transdermal nitroglycerin patches are most appropriately used to prevent the occurrence of angina. Nitroglycerin is a vasodilator that works by relaxing and widening blood vessels, which helps to increase blood flow and oxygen to the heart muscle. By using nitroglycerin patches regularly, the patient can help prevent episodes of angina, which is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. Nitroglycerin patches are not used to prevent low blood pressure, relieve shortness of breath, or control heart rate during exercise.
Question 3 of 5
After a severe auto accident, a patient has been taken to the trauma unit and has an estimated
Correct Answer: D
Rationale: Packed red blood cells (PRBCs) are the most appropriate product to administer after a severe auto accident when there is significant blood loss and anemia. PRBCs are used to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation. They are specifically designed to deliver red blood cells without the unnecessary components found in whole blood. This targeted approach helps to avoid volume overload and reduce the risk of complications such as transfusion reactions. In a trauma situation where there is active bleeding and a need to rapidly restore oxygen-carrying capacity, PRBCs are the preferred blood product.
Question 4 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: Rotating the application sites of transdermal nitroglycerin patches is important to prevent skin irritation and tolerance development. By changing the site with each dose, the nurse ensures proper absorption of the medication and reduces the risk of skin reactions. It is not recommended to always apply the patch to the same site, as this can lead to localized skin irritation. It is also important to avoid using areas with a lot of hair or bony prominences, as well as to avoid areas with scars or skin folds. Rotation of application sites helps maintain the effectiveness of the nitroglycerin patch therapy.
Question 5 of 5
When monitoring a patient for signs of hypokalemia, the nurse looks for what early sign?
Correct Answer: D
Rationale: Muscle weakness is an early sign of hypokalemia. Potassium plays a crucial role in maintaining proper muscle function, so low potassium levels can lead to muscle weakness and fatigue. As potassium is essential for nerve impulses and muscle contractions, a decrease in potassium can impair muscle strength and function.
Therefore, when monitoring a patient for signs of hypokalemia, the nurse should look for muscle weakness as an early indicator. Seizures, cardiac dysrhythmias, and diarrhea are potential complications that can occur if hypokalemia is severe and left untreated.
