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 provider is providing range of motion to the shoulder and must perform external rotation. Which action will the provider take?

• A. Moves the patient's arm in a full circle.
• B. Moves the patient's arm across the body as far as possible.
• C. Moves the patient's arm behind the body, keeping the elbow straight.
• D. Moves the patient's arm until the thumb is upward and lateral to the head with the elbow flexed.

Correct answer: D

Rationale: The correct action for external rotation of the shoulder involves moving the patient's arm until the thumb is upward and lateral to the head with the elbow flexed. This position maximizes external rotation at the shoulder joint. Choices A, moving the arm in a full circle, B, moving the arm across the body, and C, moving the arm behind the body with the elbow straight, do not describe external rotation and are incorrect. Therefore, Choice D is the correct action for performing external rotation.

3. After repositioning a client who reports shortness of breath, which of the following actions should the nurse take next?

• A. Observe the rate, depth, and character of the client's respirations.
• B. Take the client’s blood pressure.
• C. Assess the client's pulse.
• D. Offer supplemental oxygen.

Correct answer: A

Rationale: Observing the rate, depth, and character of the client's respirations is crucial after repositioning a client experiencing shortness of breath. This action provides immediate information about the client's respiratory status. Checking blood pressure (Choice B) is not the priority in this situation, as assessing respirations is more urgent. Assessing the pulse (Choice C) is also important but does not provide direct information about the client's respiratory status. Offering supplemental oxygen (Choice D) may be necessary based on the assessment of respirations, but it should not be the first action taken without assessing the client's breathing pattern.

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. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Place the tablet under your tongue and let it dissolve completely.
• C. Swallow the tablet whole with a glass of water.
• D. Chew the tablet for faster relief.

Correct answer: B

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to place the tablet under the tongue and let it dissolve completely. This route of administration allows for rapid absorption of the medication through the oral mucosa, providing quick relief for angina symptoms. Option A, taking the medication with food, is incorrect as nitroglycerin should be taken sublingually, not with food. Option C, swallowing the tablet whole with water, is incorrect as sublingual tablets should not be swallowed whole. Option D, chewing the tablet for faster relief, is also incorrect as chewing the tablet can lead to rapid absorption and potential adverse effects rather than a controlled release for angina relief.
