1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A client with iron-deficiency anemia asks a nurse why the Z-track method is necessary for administering iron dextran. Which response should the nurse provide?

• A. It decreases the risk of injecting medication into a blood vessel.
• B. It delays medication absorption.
• C. It minimizes tissue irritation.
• D. It accelerates medication excretion.

Correct answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.

3. A 15-year-old client has been placed in a Milwaukee Brace. Which statement from the adolescent indicates the need for additional teaching?

• A. I will only have to wear this for 6 months.
• B. I should inspect my skin daily.
• C. The brace will be worn day and night.
• D. I can take it off when I shower.

Correct answer: A

Rationale: The correct answer is A. The statement 'I will only have to wear this for 6 months' indicates a need for additional teaching because the Milwaukee Brace is typically worn for 12-18 months, not just 6 months. Choice B is correct as inspecting the skin daily is important to prevent skin breakdown. Choice C is correct as the brace is usually worn day and night for effectiveness. Choice D is correct as the brace can be removed when showering to maintain hygiene.

4. A healthcare professional is measuring vital signs for a client and notices an irregularity in the pulse. Which of the following actions should the healthcare professional take?

• A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart.
• B. Recheck the pulse at the same site after 5 minutes.
• C. Measure the client’s blood pressure.
• D. Record the irregularity and continue with other vital signs.

Correct answer: A

Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.

5. A healthcare provider is preparing to insert an IV catheter into a client's arm before starting IV fluid therapy. Which of the following interventions should the provider implement to prevent infection?

• A. Thread the IV catheter so that the hub rests at the insertion site
• B. Shave excess hair from around the insertion site
• C. Cleanse the site with hydrogen peroxide before IV catheter insertion
• D. Palpate the site carefully just before inserting the IV catheter

Correct answer: A

Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.
