Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. The healthcare provider is caring for a client with jaundice. Which serum laboratory value is likely to be elevated for this client?

• A. Amylase
• B. Creatinine
• C. Blood urea nitrogen
• D. Bilirubin

Correct answer: D

Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.

3. The nurse is performing a physical assessment of a male client who has chronic renal failure. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Client reports difficulty breathing
• B. Client reports shortness of breath when lying flat
• C. Client reports swelling in the feet and ankles
• D. Client reports a metallic taste in the mouth

Correct answer: A

Rationale: In a client with chronic renal failure, difficulty breathing is the most critical finding to report. This symptom may indicate fluid overload or pulmonary edema, which can be life-threatening. Shortness of breath when lying flat (orthopnea) is also concerning but less urgent than difficulty breathing. Swelling in the feet and ankles (edema) is a common finding in renal failure but may not be as immediately critical as difficulty breathing. A metallic taste in the mouth is associated with uremia, a common complication of chronic renal failure, but it is not as urgent as respiratory distress.

4. A nurse is preparing to insert an indwelling urinary catheter in a female client. Which action should the nurse take to maintain sterile technique?

• A. Apply sterile gloves before inserting the catheter
• B. Use sterile gloves to insert the catheter
• C. Clean the urinary meatus with an antiseptic solution
• D. Place the drainage bag above the level of the bladder

Correct answer: B

Rationale: Using sterile gloves to insert the catheter is crucial to maintaining sterile technique. Sterile gloves help prevent the introduction of microorganisms during the insertion process. Applying sterile gloves before cleansing the perineal area (Choice A) is important but not specific to maintaining sterility during catheter insertion. Cleaning the urinary meatus with an antiseptic solution (Choice C) is a step in the catheterization process but does not solely ensure sterile technique. Placing the drainage bag above the level of the bladder (Choice D) is incorrect; the bag should be placed below the level of the bladder to facilitate urine drainage.

5. When caring for a laboring client whose contractions are occurring every 2 to 3 min, the nurse should document that the pump is infusing how many ml/hr?

• A. 42
• B. 50
• C. 60
• D. 70

Correct answer: A

Rationale: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.
