Nursing Elites

1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

2. A client with diabetes mellitus is admitted with a blood glucose level of 640 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer IV fluids as prescribed
• C. Check the client's blood glucose level
• D. Prepare the client for immediate dialysis

Correct answer: B

Rationale: Administering IV fluids as prescribed is the priority intervention in a client with a blood glucose level of 640 mg/dl and unresponsiveness. Severe hyperglycemia can lead to dehydration and electrolyte imbalances, and administering IV fluids can help manage hyperglycemia and prevent further complications. Administering dextrose IV push (Choice A) can exacerbate hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the immediate priority when the client is unresponsive. Immediate dialysis (Choice D) is not indicated as the first intervention for hyperglycemia.

3. An older female client tells the nurse that her muscles have gradually been getting weaker. What is the best initial response by the nurse?

• A. Explain that this is an expected occurrence with aging.
• B. Observe the lower extremities for signs of muscle atrophy.
• C. Review the medical record for recent diagnostic test results.
• D. Ask the client to describe the changes that have occurred.

Correct answer: D

Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.

4. A client with a nasogastric tube in place following gastric surgery reports nausea. What is the most appropriate nursing action?

• A. Irrigate the NG tube with 30 ml of normal saline.
• B. Administer an antiemetic as prescribed.
• C. Assess the NG tube for patency and reposition if necessary.
• D. Provide sips of water and reassess the client's symptoms.

Correct answer: C

Rationale: Assessing the NG tube for patency and repositioning it if necessary is the most appropriate action to relieve the client's nausea. Nausea in a client with a nasogastric tube can be due to the tube's malposition or blockage. Irrigating the NG tube with normal saline (Choice A) without assessing for patency or repositioning may worsen the situation. Administering an antiemetic (Choice B) can help manage symptoms but does not address the potential issue with the NG tube. Providing sips of water and reassessing symptoms (Choice D) may be contraindicated if there is a problem with the NG tube and could exacerbate the nausea.

5. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?

• A. Serum glucose of 600 mg/dL
• B. Serum osmolarity of 320 mOsm/kg
• C. Serum sodium of 130 mEq/L
• D. Serum potassium of 5.0 mEq/L

Correct answer: B

Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
