Question 1 of 5
A patient who is severely anemic also has acute heart failure with severe edema due to fluid
Correct Answer: D
Rationale: In a patient who is severely anemic, the primary goal is to raise the hemoglobin and hematocrit levels. Packed red blood cells (PRBCs) contain a concentrated dose of red blood cells and are given to increase oxygen-carrying capacity in cases of significant anemia. Fresh frozen plasma, albumin, and whole blood do not specifically address the issue of low hemoglobin levels, making them less appropriate choices for this scenario.
Question 2 of 5
Hemostatic agents that arrest the flow of blood from small vessels by precipitating the tissue proteins in the immediate area:
Correct Answer: B
Rationale: Styptics and astringents are hemostatic agents that work by precipitating tissue proteins in the immediate area of a small vessel to stop bleeding. Styptics such as alum, silver nitrate, and ferric subsulfate directly induce coagulation at the site of bleeding, forming a protective scab to stop the flow of blood. Astringents like tannic acid work by tightening the tissue proteins around the blood vessel to create a seal and halt bleeding. These agents are commonly used in the management of minor cuts and wounds to promote hemostasis.
Question 3 of 5
A 54-year-old man with an attack of gout approximately 4 months ago was placed on allopurinol. He now presents to his primary care physician complaining of a skin rash on his arms. Allopurinol was discontinued 3 months ago. What is the most likely explanation for this finding?
Correct Answer: A
Rationale: Rash 3 months after stopping allopurinol suggests contact dermatitis . Allopurinol's hypersensitivity resolves faster. Dermatitis herpetiformis , carcinoma , and telangiectasia (E) don't fit. An external allergen likely caused this delayed presentation.
Question 4 of 5
what is the route of INSULIN GLARGINE:
Correct Answer: A
Rationale: Insulin glargine is a type of long-acting insulin that is given via subcutaneous injection. Subcutaneous administration involves injecting the medication into the fatty tissue layer just beneath the skin. This route allows for slow and consistent absorption of the insulin into the bloodstream, providing a prolonged effect on lowering blood sugar levels. Insulin cannot be taken orally because it would be broken down by the digestive system before it could be effective. Intravenous (IV) administration is also not appropriate for insulin glargine because it is meant to have a slow, sustained release in the body, which cannot be achieved with IV administration. Sublingual administration, where a medication is placed under the tongue for absorption, is not suitable for insulin as it requires specific pathways for absorption that are not present under the tongue.
Question 5 of 5
What should the nurse include when teaching a patient regarding the use of omeprazole?
Correct Answer: B
Rationale: Omeprazole, a proton pump inhibitor (PPI), is most effective when taken 30 minutes before meals. This allows the medication to inhibit proton pumps during meal-stimulated acid production. Taking it after (A) or with meals (C) reduces its effectiveness. While it can be taken without regard to meals (D), taking it before meals is optimal.
