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. The healthcare provider is caring for a client with a history of hypertension. Which assessment finding would be most concerning?

• A. Blood pressure of 150/90 mmHg
• B. Irregular heart rate
• C. Shortness of breath
• D. Headache

Correct answer: C

Rationale: Shortness of breath in a client with a history of hypertension is a critical assessment finding as it may indicate heart failure, pulmonary edema, or other severe complications. The development of shortness of breath suggests that the client's condition may be rapidly deteriorating and requires immediate medical attention. Elevated blood pressure (150/90 mmHg) is concerning but not as acute as the potential complications associated with shortness of breath. An irregular heart rate and headache can also be symptoms of hypertension, but in this scenario, shortness of breath poses a higher risk of severe cardiovascular or respiratory issues.

3. A nurse is preparing to review medication documentation with a group of newly licensed nurses. Which of the following statements should the nurse manager plan to include in the teaching?

• A. Use the complete name of the medication magnesium sulfate
• B. Maintain the space between the numerical dose and the unit of measure
• C. Note the dosage of insulin in units
• D. Use 'subcut' for indicating a subcutaneous injection

Correct answer: A

Rationale: The correct answer is A. The Institute for Safe Medication Practices recommends using the complete medication name magnesium sulfate when documenting medications to prevent misinterpretation. Choice B is incorrect because spaces should be maintained between the numerical dose and unit of measure for clarity. Choice C is incorrect as the standard notation for insulin dosage is in units, not using the letter U. Choice D is incorrect as the abbreviation for subcutaneous injection is commonly written as 'subcut' or 'subcutaneous,' not as SC.

4. During an IV catheter insertion demonstration, which statement by a nurse indicates understanding of the procedure?

• A. “I will thread the needle into the vein at an angle of 10 to 30 degrees with the bevel up.”
• B. “I will insert the needle into the client’s skin at an angle of 10 to 30 degrees with the bevel up.”
• C. “I will apply pressure approximately 1.2 inches below the insertion site before removing the needle.”
• D. “I will select a vein in the antecubital fossa for IV insertion based on its size and easily accessible location.”

Correct answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.

5. A client with a history of asthma presents to the emergency department with difficulty breathing and wheezing. Which of the following is the priority nursing action?

• A. Administer a bronchodilator
• B. Obtain a peak flow reading
• C. Provide supplemental oxygen
• D. Assess the client's respiratory rate

Correct answer: A

Rationale: In a client with a history of asthma experiencing difficulty breathing and wheezing, the priority nursing action is to administer a bronchodilator. This intervention helps relieve bronchospasm and improve the client's breathing. Obtaining a peak flow reading can provide additional information but is not the immediate priority in this situation. Providing supplemental oxygen may be needed but addressing the bronchospasm with a bronchodilator takes precedence. Assessing the client's respiratory rate is important but not as urgent as administering a bronchodilator to address the breathing difficulty.
