A patient with a history of HF presents to the emergency department with difficulty breathing, cough, and edema of the lower extremities. The nurse anticipates administration of which type of medication?

Correct Answer: C

Rationale: In the scenario described, the patient with a history of heart failure (HF) is presenting with symptoms of difficulty breathing, cough, and edema of the lower extremities. These signs and symptoms suggest acute decompensated heart failure (ADHF), which is characterized by a decrease in cardiac output and inadequate tissue perfusion. In this situation, the nurse would anticipate the administration of a positive inotrope medication.

Correct Answer: C

Rationale: The most common side effect that is normal with the initial therapy of Nitroglycerine due to increased vasodilation is a headache. Nitroglycerine causes vasodilation of blood vessels, including the blood vessels in the head and brain. This can lead to headaches as a result of the increased blood flow and changes in blood vessel diameter. Headaches caused by Nitroglycerine are usually mild and transient. It is important to monitor patients for this expected side effect and educate them about it to ensure compliance with the medication regimen.

Correct Answer: A

Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work by decreasing glucose production in the liver and also improving insulin sensitivity in the muscles, helping to lower blood sugar levels in patients with type 2 diabetes. Additionally, metformin can also reduce glucose absorption in the intestines and increase glucose uptake in peripheral tissues. Its main pharmacological action is to improve glycemic control and reduce hyperglycemia in patients with diabetes.

Correct Answer: A

Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work primarily by decreasing glucose production in the liver and increasing insulin sensitivity in peripheral tissues, such as muscles. They also help improve glucose uptake and utilization by cells, leading to better control of blood sugar levels. Metformin is commonly used to treat type 2 diabetes mellitus and can also be used in the management of polycystic ovary syndrome (PCOS).
