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 healthcare professional is obtaining the blood pressure in a client's lower extremity. Which of the following actions should the healthcare professional take?

• A. Place the bladder of the cuff over the posterior aspect of the thigh
• B. Use a smaller cuff designed for lower extremities
• C. Place the cuff around the client's ankle
• D. Ensure the cuff is positioned above the knee

Correct answer: A

Rationale: When measuring blood pressure in the lower extremity, the bladder of the cuff should be placed over the posterior aspect of the thigh. This positioning ensures an accurate measurement. Placing the cuff around the ankle (Choice C) or above the knee (Choice D) would not provide an accurate blood pressure reading in the lower extremity. Using a smaller cuff designed for lower extremities (Choice B) is not appropriate as the standard cuff size should be used with the bladder placed over the posterior aspect of the thigh.

3. A client has a new prescription for a home oxygen concentrator. Which of the following instructions should the nurse provide to the client and their family?

• A. Check the cord routinely for frays or tearing
• B. Use oxygen around open flames
• C. Store oxygen concentrator in a closet
• D. Wear synthetic clothing to prevent static electricity

Correct answer: A

Rationale: The correct answer is to instruct the client and their family to check the cord routinely for frays or tearing. This is crucial to ensure the safety and proper function of the oxygen concentrator. Choice B is incorrect because oxygen should never be used around open flames due to the risk of fire. Choice C is also incorrect as oxygen cylinders or concentrators should not be stored in a closet due to ventilation and safety concerns. Choice D is incorrect because synthetic clothing can generate static electricity, which could pose a risk around oxygen equipment.

4. A school-aged child has had a long leg (hip to ankle) synthetic cast applied 4 hours ago. Which statement from the mother indicates that teaching has been inadequate?

• A. I will keep the cast covered the next day to prevent skin burning.
• B. I can apply an ice pack over the area to relieve itching inside the cast.
• C. The cast should be propped on at least 2 pillows when my child is lying down.
• D. I think I remember that standing cannot be done until after 72 hours.

Correct answer: D

Rationale: The correct answer is D because there is no need to wait 72 hours before allowing the child to stand. The synthetic cast does not affect weight-bearing capacity, and standing can be done as tolerated. Choice A is incorrect because keeping the cast covered can lead to damage or accidents. Choice B is acceptable as applying an ice pack can help relieve itching. Choice C is also correct as elevating the cast on pillows can help reduce swelling and promote comfort during rest.

5. The healthcare provider is monitoring a client in active labor. Which pattern on the fetal heart monitor requires immediate intervention?

• A. Early decelerations
• B. Late decelerations
• C. Accelerations
• D. Moderate variability

Correct answer: B

Rationale: Late decelerations are concerning as they indicate uteroplacental insufficiency, potentially resulting in fetal hypoxia. Immediate intervention is necessary to address the underlying cause and ensure fetal well-being. Early decelerations are typically benign and associated with head compression during contractions. Accelerations are reassuring and indicate fetal well-being. Moderate variability is a normal finding and indicates a healthy autonomic nervous system response. Therefore, late decelerations (Choice B) require immediate attention, while the other patterns are generally considered normal or benign during labor.
