A patient is being discharged on anticoagulant therapy. The nurse will include in the patient- education conversation that it is important to avoid herbal products that contain which substance?

Correct Answer: B

Rationale: Ginkgo is known to have anticoagulant properties that can interact with and enhance the effects of anticoagulant medications, such as warfarin. Therefore, patients taking anticoagulant therapy should avoid herbal products containing ginkgo to prevent excessive anticoagulation and the risk of bleeding complications. It is essential for healthcare providers to educate patients on potential herb-drug interactions to ensure their safety and optimal therapeutic outcomes.

Correct Answer: A

Rationale: Premature infants, especially those born very premature or with health complications, often require blood transfusions due to their underdeveloped organs and medical conditions. Their small size and medical fragility make them the age group that typically uses the most units of blood and blood products. This high demand for blood products is necessary to support their growth, development, and overall health. Conversely, while individuals in other age groups may also require blood transfusions, premature infants have specific and ongoing needs that often result in a greater overall use of blood and blood products in this age group.

Correct Answer: A

Rationale: Angiotensin II receptor agents medications usually end in -sartan. Examples of such medications include losartan, valsartan, and telmisartan. These drugs work by blocking the action of angiotensin II at its receptor sites, resulting in vasodilation and decreased aldosterone secretion. This class of medications is commonly used to treat conditions like hypertension, heart failure, and diabetic nephropathy.

Correct Answer: C

Rationale: Iron is classified as an Antianemic agent. Anemia is a condition characterized by a lack of healthy red blood cells, which are responsible for carrying oxygen to the body's tissues. Iron is essential for the production of hemoglobin, the protein in red blood cells that binds oxygen. Therefore, iron supplements are commonly used to treat iron-deficiency anemia by replenishing the body's iron stores and supporting the production of healthy red blood cells.

Correct Answer: A

Rationale: Atropine given via intramuscular (IM) injection typically reaches its peak effects within 15 to 50 minutes after administration. The onset of action is relatively rapid, with faster absorption and distribution compared to oral administration. The effects of atropine can be seen within minutes, reaching peak concentration within the specified time frame. This rapid onset is important clinically when atropine is used to treat conditions such as bradycardia or nerve agent poisoning where a quick response is needed.
