Adult Health 2 Exam 1
1. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
2. What is the most important action to prevent complications while caring for a client receiving enteral nutrition via a nasogastric tube?
- A. Check tube placement before each feeding
- B. Flush the tube with water before and after each feeding
- C. Elevate the head of the bed to 30 degrees
- D. Administer the feeding at room temperature
Correct answer: A
Rationale: Checking tube placement before each feeding is crucial to prevent aspiration, a serious complication of enteral nutrition. Ensuring the tube is correctly positioned in the stomach helps avoid the risk of the feeding going into the lungs, which can lead to aspiration pneumonia. Flushing the tube with water (Choice B) is important for maintaining tube patency but is not the most critical action to prevent complications. Elevating the head of the bed (Choice C) helps reduce the risk of aspiration but is not as crucial as verifying tube placement. Administering the feeding at room temperature (Choice D) is more related to patient comfort and does not directly address the prevention of complications associated with enteral nutrition via a nasogastric tube.
3. 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.
4. A client is being treated for dehydration. Which clinical finding would indicate that treatment is effective?
- A. Dry mucous membranes
- B. Increased urine output
- C. Tachycardia
- D. Hypotension
Correct answer: B
Rationale: The correct answer is B: Increased urine output. When a client is being treated for dehydration, increased urine output is a positive indication that the treatment is effective. This signifies that the body is beginning to rehydrate and eliminate excess fluid. Choices A, C, and D are incorrect because dry mucous membranes, tachycardia, and hypotension are all associated with dehydration and would not be signs of effective treatment.
5. A client with chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?
- A. Use oxygen at the highest flow rate tolerated
- B. Avoid wearing oxygen during physical activity
- C. Do not smoke while using oxygen
- D. Store oxygen tanks in a cool, dark place
Correct answer: C
Rationale: The correct answer is C: 'Do not smoke while using oxygen.' Smoking while using oxygen can lead to a serious fire hazard, as oxygen supports combustion. This instruction is crucial to prevent potential harm to the client. Choices A, B, and D are incorrect. Using oxygen at the highest flow rate tolerated can be harmful, avoiding wearing oxygen during physical activity may limit the client's mobility unnecessarily, and storing oxygen tanks in a cool, dark place, although important, is not as critical as the instruction to avoid smoking while using oxygen.
