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 client has a new prescription for a metered-dose inhaler. Which of the following instructions should the nurse include?

• A. Inhale quickly and deeply while pressing down on the inhaler.
• B. Hold your breath for 10 seconds after inhaling the medication.
• C. Exhale immediately after inhaling the medication.
• D. Shake the inhaler before each use.

Correct answer: B

Rationale: The correct instruction for using a metered-dose inhaler is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to be absorbed more effectively in the lungs. Inhaling quickly and deeply while pressing down on the inhaler (Choice A) may cause the medication to deposit in the mouth and throat rather than reaching the lungs. Exhaling immediately after inhaling the medication (Choice C) may also lead to medication wastage. Shaking the inhaler before each use (Choice D) is not necessary for all types of inhalers and can sometimes cause improper drug delivery.

3. How can self-injury be prevented when lifting a bedside cabinet?

• A. Standing close to the cabinet when lifting.
• B. Bending at the waist when lifting.
• C. Twisting while lifting to balance the load.
• D. Lifting with a quick motion.

Correct answer: A

Rationale: The correct way to prevent self-injury when lifting a bedside cabinet is by standing close to the cabinet. By standing close, the individual can maintain better control and balance while lifting, reducing the risk of injury. Bending at the waist when lifting (choice B) can strain the back and lead to injury. Twisting while lifting (choice C) can also cause strain and imbalance. Lifting with a quick motion (choice D) can increase the risk of injury due to lack of control and improper body mechanics.

4. When admitting a client with an abdominal wound, which precaution should be taken?

• A. Contact precautions
• B. Droplet precautions
• C. Airborne precautions
• D. Standard precautions

Correct answer: A

Rationale: When admitting a client with an abdominal wound, contact precautions should be implemented. Contact precautions are used to prevent the spread of infections that are spread by direct or indirect contact. In the case of abdominal wounds, bacteria and pathogens can easily be transmitted through contact with the wound or wound drainage. Droplet precautions are used for infections transmitted through respiratory droplets, such as influenza. Airborne precautions are used for infections spread through the air, like tuberculosis. Standard precautions are used for all clients to prevent the spread of infections and should be followed in addition to specific precautions based on the type of infection.

5. During an eye assessment, what action should the nurse take to assess a client's extraocular eye movements?

• A. Position the client 6.1 m (20 ft) away from the Snellen chart
• B. Instruct the client to follow a finger through the six cardinal positions of gaze
• C. Ask the client to cover their right eye during assessment of the left eye
• D. Hold a finger 46 cm (18 inches) away from the client's eye

Correct answer: B

Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action to assess extraocular eye movements effectively. This technique evaluates the function of the six extraocular muscles and cranial nerves III, IV, and VI. Positioning the client 6.1 m away from the Snellen chart is more relevant for visual acuity testing. Asking the client to cover their right eye during the assessment is not necessary for evaluating extraocular movements. Holding a finger at a specific distance in front of the client's eye is not an appropriate method for assessing extraocular eye movements.
