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. While observing a student nurse administering a narcotic analgesic IM injection without aspirating, what should the nurse do?

• A. Ask the student, 'What did you forget to do?'
• B. Stop and explain why aspiration is needed.
• C. Quietly state, 'You forgot to aspirate.'
• D. Walk up and whisper in the student's ear, 'Stop. Aspirate. Then inject.'

Correct answer: D

Rationale: When the nurse observes a student nurse making a mistake during a procedure, such as not aspirating before administering a medication, the nurse should provide immediate, discreet feedback to correct the error. Walking up and whispering in the student's ear to stop, aspirate, and then inject is appropriate as it corrects the mistake while maintaining the student's dignity and confidence. Option A is not as effective as it indirectly addresses the issue. Option B is not the best approach as the student needs immediate correction. Option C is not ideal as loudly stating the mistake may embarrass the student and is not necessary for a discreet correction.

3. A hospitalized male client is receiving nasogastric tube feedings via a small-bore tube and a continuous pump infusion. He reports that he had a bad bout of severe coughing a few minutes ago but feels fine now. What action is best for the LPN/LVN to take?

• A. Record the coughing incident. No further action is required at this time.
• B. Stop the feeding, explain to the family why it is being stopped, and notify the healthcare provider.
• C. After clearing the tube with 30 ml of air, check the pH of fluid withdrawn from the tube.
• D. Inject 30 ml of air into the tube while auscultating the epigastrium for gurgling.

Correct answer: C

Rationale: After a client experiences severe coughing following nasogastric tube feedings, it is crucial to verify proper tube placement. Checking the pH of fluid withdrawn from the tube helps confirm the tube's correct positioning. Option A is incorrect because further action is necessary to ensure the client's safety. Option B is inappropriate as it suggests stopping the feeding without assessing the tube's placement. Option D is incorrect as injecting air into the tube may lead to further complications if the tube is not positioned correctly.

4. A nurse is reviewing evidence-based practice principles about the administration of oxygen therapy with a newly licensed nurse. Which of the following actions should the nurse include?

• A. Regulate oxygen via nasal cannula at a flow rate no more than 6 L/min
• B. Administer oxygen at a higher flow rate for better saturation
• C. Use a high-flow nasal cannula for all clients
• D. Adjust oxygen flow based on client comfort

Correct answer: A

Rationale: The correct answer is A. Regulating oxygen flow at no more than 6 L/min via nasal cannula is a safe practice to prevent potential complications such as oxygen toxicity. Option B suggesting administering oxygen at a higher flow rate for better saturation is incorrect as it can lead to adverse effects. Option C is incorrect because using a high-flow nasal cannula for all clients is not necessary and should be based on individual client needs. Option D is incorrect as adjusting oxygen flow solely based on client comfort without considering the prescribed flow rate can compromise the effectiveness of oxygen therapy.

5. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?

• A. 31 gtt/min.
• B. 62 gtt/min.
• C. 93 gtt/min.
• D. 124 gtt/min.

Correct answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
