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. 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.

3. One week after being told that she has terminal cancer with a life expectancy of 3 weeks, a female client tells the nurse, 'I think I will plan a big party for all my friends.' How should the nurse respond?

• A. You may not have enough energy before long to hold a big party.
• B. Do you mean to say that you want to plan your funeral and wake?
• C. Planning a party and thinking about all your friends sounds like fun.
• D. You should be thinking about spending your last days with your family.

Correct answer: C

Rationale: Setting goals that bring pleasure is appropriate and should be encouraged by the nurse. Choice A is discouraging and focuses on limitations. Choice B jumps to a conclusion and is not in line with the client's statement. Choice D dictates what the client should be doing, which is not respectful of the client's autonomy. Therefore, the most appropriate response is C, as it acknowledges the client's wishes and provides positive reinforcement without perpetuating denial.

4. A healthcare professional is teaching a new colleague about the correct administration of subcutaneous (subQ) injections. Which instruction should the healthcare professional include?

• A. Insert the needle at a 90-degree angle for subQ injections
• B. Aspirate for blood return before injecting the medication
• C. Pinch the skin before inserting the needle
• D. Massage the site after administering the injection

Correct answer: C

Rationale: Pinching the skin before inserting the needle is essential in elevating the subcutaneous tissue away from the muscle. This technique ensures that the medication is administered into the correct tissue layer, promoting proper absorption and decreasing the risk of injecting into muscle tissue.

5. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.
