HESI LPN
Adult Health 2 Exam 1
1. The nurse plans to evaluate the effectiveness of several drugs administered by different routes. Arrange the routes of administration from fastest to slowest rate of absorption. 1. Intravenous 2. Sublingual 3. Intramuscular 4. Subcutaneous
- A. 1,2,3,4
- B. 4,3,2,1
- C. 2,4,3,1
- D. 3,4,1,2
Correct answer: A
Rationale: The correct order of routes of administration from fastest to slowest rate of absorption is 1. Intravenous, 2. Sublingual, 3. Intramuscular, 4. Subcutaneous. Intravenous administration provides the fastest absorption as the drug is directly injected into the bloodstream. Sublingual administration allows for rapid absorption through the mucous membranes under the tongue. Intramuscular administration has a slower absorption rate as the drug is injected into the muscle tissue. Subcutaneous administration is the slowest as the drug is injected into the fatty tissue under the skin, leading to a slower absorption compared to the other routes.
2. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?
- A. 15 degrees
- B. 30 degrees
- C. 45 degrees
- D. 90 degrees
Correct answer: C
Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.
3. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?
- A. Stimulates insulin secretion from the pancreas.
- B. Increases insulin sensitivity in various tissues.
- C. Decreases hepatic glucose production.
- D. Delays absorption of glucose from the intestines.
Correct answer: C
Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
4. The client is being taught about managing chronic kidney disease (CKD). Which dietary restriction should be emphasized the most?
- A. Limit consumption of high-fiber foods
- B. Restrict protein intake
- C. Avoid dairy products
- D. Increase fluid intake
Correct answer: B
Rationale: Restricting protein intake is vital in managing chronic kidney disease (CKD) as it helps decrease the kidneys' workload and slows down disease progression. High-fiber foods are generally beneficial for health and should not be limited in CKD management. Dairy products can be consumed moderately unless contraindicated. While adequate fluid intake is crucial, increasing intake excessively may not be suitable for all CKD patients, especially those with fluid restrictions. Therefore, the most crucial dietary restriction to emphasize in CKD management is restricting protein intake.
5. The client with a new diagnosis of type 2 diabetes is being taught about diet management by the nurse. Which statement by the client indicates effective learning?
- A. I should not avoid all carbohydrates
- B. I can eat whatever I want as long as I take my medication
- C. I need to eat regular meals and snacks to maintain my blood sugar levels
- D. I will decrease my intake of sugary foods to prevent low blood sugar
Correct answer: C
Rationale: Choice C is the correct answer because eating regular meals and snacks is crucial for maintaining stable blood sugar levels in individuals with diabetes. This approach helps prevent spikes and drops in blood sugar, promoting better management of the condition. Choices A, B, and D are incorrect. Avoiding all carbohydrates is not recommended as they are a major energy source and can be part of a balanced diet; eating whatever one wants while relying solely on medication can lead to uncontrolled blood sugar levels and complications; decreasing sugary foods intake can actually contribute to high blood sugar levels rather than preventing low blood sugar.
