Nursing Elites

1. A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?

• A. Hemoglobin 9.5 g/dL
• B. Potassium 6.2 mEq/L
• C. Creatinine 3.5 mg/dL
• D. BUN 50 mg/dL

Correct answer: B

Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.

2. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

3. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?

• A. Administer bronchodilator therapy as prescribed.
• B. Inhale the medication slowly while pressing down on the inhaler.
• C. Position the client in a high-Fowler's position.
• D. Increase the oxygen flow rate.

Correct answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.

4. The nurse is in charge of a Nursing unit in a long-term care facility. Which task is best for the nurse to assign to an unlicensed assistive personnel (UAP) who is helping with the care of several clients?

• A. Measure the amount of a client's residual urine after voiding
• B. Cleanse the perineal area of a client with urinary incontinence
• C. Insert a straight catheter to obtain a urine specimen for culture
• D. Provide catheter care for a client with a suprapubic catheter

Correct answer: B

Rationale: The correct answer is B because cleaning the perineal area is a task within the scope of practice for unlicensed assistive personnel (UAPs) and is crucial for preventing infections. Choice A involves a more complex task that requires a healthcare provider's assessment. Choice C involves a sterile procedure that should be performed by licensed staff. Choice D involves specific care for a client with a catheter that exceeds the UAP's scope of practice.

5. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
