Nursing Elites

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 provider prescribes cold application for a client who reports ankle joint stiffness. Which of the following assessment findings should the nurse identify as a contraindication to the application of cold?

• A. Capillary refill of 4 seconds
• B. 7.5 cm (3 in) diameter bruise on the ankle
• C. Warts on the affected ankle
• D. 2+ pitting edema

Correct answer: A

Rationale: The correct answer is A. Capillary refill of 4 seconds indicates poor circulation, which is a contraindication to cold application as it could worsen the condition by further reducing blood flow. Choice B, a 7.5 cm (3 in) diameter bruise on the ankle, does not directly contraindicate cold application but may need evaluation for possible underlying injuries. Choice C, warts on the affected ankle, do not necessarily contraindicate cold application. Choice D, 2+ pitting edema, is not a direct contraindication to cold application but may need to be addressed separately.

3. An elderly male client who is unresponsive following a cerebral vascular accident (CVA) is receiving bolus enteral feedings through a gastrostomy tube. What is the best client position for the administration of bolus tube feedings?

• A. Prone.
• B. Fowler's.
• C. Sims'.
• D. Supine.

Correct answer: B

Rationale: The correct answer is Fowler's position. Placing the client in Fowler's position, with the head of the bed elevated to 45-60 degrees, reduces the risk of aspiration during bolus enteral feedings by facilitating the flow of the feeding into the stomach. Prone position (choice A) is lying face down, which is not suitable for feeding. Sims' position (choice C) is a side-lying position used for rectal examinations or enemas, not for feeding. Supine position (choice D) is lying flat on the back and is not optimal for reducing the risk of aspiration during bolus tube feedings.

4. How should the nurse transcribe the dosage of this medication on the client's medical record?

• A. 0.3 mg
• B. 0.3 mg
• C. 0.30 mg
• D. 3/10 mg

Correct answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.

5. When should the client administer the inhaler-delivered medication to demonstrate correct use of the inhaler?

• A. Immediately after exhalation.
• B. During the inhalation.
• C. At the end of three inhalations.
• D. Immediately after inhalation.

Correct answer: B

Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.
