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 palpating the right upper hypochondriac region of the abdomen of a client. What organ lies underneath this area?
- A. Duodenum
- B. Gastric pylorus
- C. Liver
- D. Spleen
Correct answer: C
Rationale: The correct answer is C: Liver. The liver is located in the right upper hypochondriac region of the abdomen. The duodenum (Choice A) is located in the right upper quadrant but not directly underneath the right upper hypochondriac region. The gastric pylorus (Choice B) is part of the stomach and is located more centrally in the abdomen. The spleen (Choice D) is located in the left upper quadrant of the abdomen, not underneath the right upper hypochondriac region.
3. What action should the nurse implement in caring for a client following an electroencephalogram (EEG)?
- A. Monitor the client's vital signs every 4 hours
- B. Assess the client's lower extremities for sensation
- C. Instruct the client to maintain bed rest
- D. Wash any paste from the client's hair and scalp
Correct answer: D
Rationale: The correct action the nurse should implement after an EEG is to wash any paste from the client's hair and scalp. This is crucial to prevent irritation and infection at the EEG site. Monitoring vital signs every 4 hours is not specifically indicated after an EEG. Assessing the client's lower extremities for sensation is unrelated to caring for a client post-EEG. While rest may be recommended after the procedure, there is no standard requirement for a specific duration of bed rest.
4. 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.
5. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?
- A. Serum glucose of 180 mg/dL
- B. Blood pH of 7.30
- C. Positive urine ketones
- D. Serum bicarbonate of 25 mEq/L
Correct answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
