1. Which situation is an example of the use of evidence-based practice in the delivery of client care?

A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab

Correct answer: C

Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.

2. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

A. skin
B. adipose tissue
C. skeletal muscle
D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

3. After assigning tasks, what is the nurse's primary responsibility?

A. Assigning any tasks that were not completed to the next nursing shift
B. Documenting completion of each task
C. Allowing each staff member to make judgments when performing the tasks
D. Following up with each staff member regarding the performance of the task and the outcomes related to implementation of the task

Correct answer: D

Rationale: The nurse's primary responsibility after assigning tasks is to follow up with each staff member regarding the task's performance and outcomes. This ensures accountability and quality care delivery. Allowing staff members to make judgments independently can compromise patient safety if they lack the necessary knowledge or experience. While documenting task completion is important, it should follow the follow-up to assess outcomes. Assigning incomplete tasks to the next shift is not ideal as it may result in unmet patient needs and increased workload for the next shift.

4. The LPN is assisting the client with an NG tube with activities of daily living. Which of these statements would indicate a need for teaching reinforcement?

A. "Since I'm not eating or drinking by mouth, I do not need to brush my teeth as often."?
B. "I should remain sitting up at a 45-degree angle or higher for 30 minutes after a feeding."?
C. "I can clean around the tube with water and mild soap."?
D. "I should avoid using Vaseline around the nostril and tube."?

Correct answer: A

Rationale: The correct answer is, "Since I'm not eating or drinking by mouth, I do not need to brush my teeth as often."? This statement indicates a need for teaching reinforcement because even when an NG tube is in place, the client should still brush their teeth twice daily. Good oral hygiene is essential to reduce the risk of introducing bacteria that may cause an infection. Choice B is incorrect because remaining sitting up at a 45-degree angle or higher for 30 minutes after a feeding is a correct statement regarding NG tube care, promoting proper digestion and reducing the risk of aspiration. Choice C is also incorrect because cleaning around the tube with water and mild soap is an appropriate practice to maintain cleanliness and prevent infection. Choice D is incorrect because advising to avoid using Vaseline around the nostril and tube is a proper instruction to prevent skin breakdown, occlusion of the tube, and potential aspiration of Vaseline into the lungs.

5. Why is monitoring Serum Vancomycin levels important?

A. to assess renal function
B. to determine therapeutic range
C. to measure trough levels
D. to evaluate antibiotic resistance

Correct answer: B

Rationale: Monitoring Serum Vancomycin levels is essential to determine the drug's therapeutic range, ensuring optimal effectiveness while avoiding toxicity. Peak levels indicate the drug's highest concentration, while trough levels represent the lowest concentration before the next dose. Assessing renal function is typically done using creatinine, BUN, or creatinine clearance tests, not Serum Vancomycin levels. Evaluating antibiotic resistance involves sensitivity testing, not monitoring Vancomycin levels. Therefore, the correct answer is to determine the therapeutic range.
