Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. A nurse is performing a gastric lavage for a client who has upper gastrointestinal bleeding. Which of the following actions should the nurse take?

• A. Instill 500 ml of solution through the NG tube
• B. Insert a large-bore NG tube
• C. Use a cold irrigation solution
• D. Instruct the client to lie on his right side

Correct answer: B

Rationale: The correct answer is B: 'Insert a large-bore NG tube.' When performing a gastric lavage for a client with upper gastrointestinal bleeding, a large-bore NG tube is used to effectively remove gastric contents and blood. Option A is incorrect because the amount of solution to instill depends on the specific situation and should be guided by the healthcare provider's order. Option C is incorrect because using a cold irrigation solution can lead to hypothermia and is not recommended. Option D is incorrect as there is no need to instruct the client to lie on his right side specifically for gastric lavage.

3. A healthcare provider is caring for a client who has a new prescription for enoxaparin. Which of the following actions should the healthcare provider take?

• A. Administer the medication intramuscularly.
• B. Inject the medication into the client's abdomen.
• C. Massage the injection site after administration.
• D. Aspirate for blood return before administering.

Correct answer: B

Rationale: The correct answer is to inject the medication into the client's abdomen. Enoxaparin is a medication that should be administered subcutaneously into the abdomen to ensure proper absorption. Choice A is incorrect because enoxaparin should not be administered intramuscularly. Choice C is incorrect because massaging the injection site after administration is not recommended for enoxaparin injections. Choice D is incorrect because aspirating for blood return is not necessary before administering a subcutaneous injection like enoxaparin.

4. A client is receiving discharge teaching for a new prescription of warfarin. Which statement by the client indicates an understanding of the teaching?

• A. I will need to increase my intake of leafy green vegetables.
• B. I will avoid drinking grapefruit juice while taking warfarin.
• C. I will have my INR checked regularly.
• D. I will take my medication at the same time each day.

Correct answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.

5. What is the best initial action when a patient presents with confusion?

• A. Administer IV fluids
• B. Perform a neurological assessment
• C. Administer electrolytes
• D. Prepare for a CT scan

Correct answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.
