Nursing Elites

1. A client has an indwelling urinary catheter. Which of the following actions should the nurse take to prevent infection?

• A. Ensure the catheter tubing is free of kinks.
• B. Clean the perineal area with antiseptic solution daily.
• C. Irrigate the catheter with normal saline every shift.
• D. Secure the catheter to the client's leg.

Correct answer: B

Rationale: Cleaning the perineal area with antiseptic solution daily is essential to prevent infection when caring for a client with an indwelling urinary catheter. This practice helps reduce the risk of introducing pathogens into the urinary tract. Ensuring the catheter tubing is free of kinks (Choice A) is important for maintaining proper urine flow but is not directly related to preventing infection. Irrigating the catheter with normal saline every shift (Choice C) is not a routine practice and can increase the risk of introducing pathogens. Securing the catheter to the client's leg (Choice D) is important for stability but does not directly prevent infection.

2. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?

• A. The nurse opens the sterile field on a wet surface.
• B. The nurse turns away from the sterile field.
• C. The nurse uses a non-sterile glove to touch the sterile field.
• D. The nurse touches the edge of the sterile drape with her hand.

Correct answer: A

Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.

3. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

4. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

5. The nurse is providing care for a client who is receiving total parenteral nutrition (TPN). Which laboratory value should the nurse monitor closely to assess for complications?

• A. Serum potassium
• B. Blood glucose
• C. Serum sodium
• D. Serum calcium

Correct answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the increased risk of hyperglycemia associated with TPN infusion. Elevated blood glucose levels can lead to complications such as hyperglycemia, which can be harmful to the client. While monitoring serum potassium (Choice A), serum sodium (Choice C), and serum calcium (Choice D) are also important aspects of care, when specifically considering TPN administration, blood glucose monitoring takes precedence due to the potential for significant complications related to glucose imbalances.
