Nursing Elites

1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?

• A. 13 ml/hour.
• B. 63 ml/hour.
• C. 80 ml/hour.
• D. 125 ml/hour.

Correct answer: B

Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.

2. The healthcare professional is assessing a client with a diagnosis of peripheral arterial disease (PAD). Which assessment finding is most indicative of this condition?

• A. Dependent rubor.
• B. Absence of hair on the lower legs.
• C. Shiny, thin skin on the legs.
• D. Pain in the legs when walking.

Correct answer: D

Rationale: Pain in the legs when walking (D), known as intermittent claudication, is most indicative of peripheral arterial disease (PAD). While dependent rubor (A), absence of hair (B), and shiny, thin skin (C) are also associated with PAD, they are less specific than intermittent claudication. Intermittent claudication is a hallmark symptom of PAD caused by inadequate blood flow to the legs during exercise, resulting in pain that resolves with rest.

3. What assessment finding places a client at risk for problems associated with impaired skin integrity?

• A. Scattered macules on the face
• B. Capillary refill of 5 seconds
• C. Smooth nail texture
• D. Presence of skin tenting

Correct answer: B

Rationale: The correct answer is B. A capillary refill time greater than 3 seconds indicates poor perfusion, leading to impaired skin integrity. Delayed capillary refill can compromise blood flow to the skin, increasing the risk of pressure ulcers or wounds due to reduced tissue perfusion. Choices A, C, and D are incorrect because scattered macules on the face, smooth nail texture, and presence of skin tenting are not direct indicators of impaired skin integrity or risk for skin problems.

4. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?

• A. Deflate the cuff completely and immediately reattempt the reading.
• B. Reinflate the cuff completely and leave it inflated for 90 to 110 seconds before taking the second reading.
• C. Deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading.
• D. Document the exact level visualized on the sphygmomanometer where the first fluctuation was seen.

Correct answer: C

Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.

5. When assessing a male client, the nurse finds that he is fatigued and experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client’s laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client’s laboratory values for potassium levels will help confirm the presence of hypokalemia.
