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 nurse reviews an immobilized patient's laboratory results and discovers hypercalcemia. Which condition will the nurse monitor for most closely in this patient?

• A. Hypostatic pneumonia
• B. Renal stones
• C. Pressure ulcers
• D. Thrombus formation

Correct answer: B

Rationale: The correct answer is B: Renal stones. Renal calculi are calcium stones that can form in the renal pelvis or pass through the ureters. Immobilized patients, who have hypercalcemia, are at increased risk for developing renal stones. Monitoring for signs and symptoms of renal stones is crucial in this patient population. Choices A, C, and D are incorrect because although they are potential complications in immobilized patients, they are not directly associated with hypercalcemia and do not match the scenario described in the question.

3. When providing a bath, in which order will the nurse clean the body, beginning with the first area?

• A. Face
• B. Eyes
• C. Perineum
• D. Back and buttocks

Correct answer: B

Rationale: The correct sequence for giving a bath starts with cleaning the eyes, followed by the face, both arms, chest, hands/nails, abdomen, both legs, perineal hygiene, back, and finally the buttocks/anus. Therefore, the first area to be cleaned during a bath is the eyes. Choices A, C, and D are incorrect as per the standard procedure for providing a bath.

4. The patient is being taught about flossing and oral hygiene. What instruction will the nurse include in the teaching session?

• A. Using waxed floss helps prevent bleeding
• B. Flossing removes plaque and tartar from the teeth
• C. Flossing at least 3 times a day is beneficial
• D. Applying toothpaste before flossing is harmful

Correct answer: B

Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.

5. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

• A. Decrease in heart rate
• B. Fluid volume deficit causes tachycardia
• C. Decrease in blood pressure
• D. Increase in respiratory rate

Correct answer: A

Rationale: A decrease in heart rate can indicate that the fluid volume deficit is improving. In cases of fluid volume deficit, the body compensates by increasing the heart rate to maintain adequate perfusion. Therefore, a decrease in heart rate after fluid resuscitation suggests that the body's perfusion status is improving. Choices B, C, and D are incorrect because fluid volume deficit typically causes tachycardia, not a decrease in heart rate, and would not result in a decrease in blood pressure or an increase in respiratory rate as primary signs of improvement.
