1. The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?

• A. 5 gtt/minute
• B. 13 gtt/minute
• C. 25 gtt/minute
• D. 50 gtt/minute

Correct answer: C

Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour ÷ 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.

2. When caring for a client who is on contact precautions, which of the following measures should the nurse include in the teaching?

• A. Remove the protective gown after leaving the client's room.
• B. Place the client in a room with negative pressure.
• C. Wear gloves when providing care to the client.
• D. Wear a mask when in the client's room.

Correct answer: C

Rationale: Contact precautions are used for clients with known or suspected infections that are spread by direct or indirect contact. The most important measure for healthcare workers when caring for a client on contact precautions is to wear gloves when providing care. This helps prevent the transmission of infectious agents between the client and the healthcare worker. Removing the protective gown after leaving the client's room, placing the client in a room with negative pressure, and wearing a mask when in the client's room are not specific to contact precautions and may not be necessary for all clients on contact precautions.

3. Which of the following vascular system changes result from aging?

• A. Increased peripheral resistance of the blood vessels
• B. Decreased blood flow
• C. Increased workload of the left ventricle
• D. All of the above

Correct answer: D

Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.

4. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

5. Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?

• A. Opening the patient’s window to the outside environment
• B. Turning on the patient’s room ventilator
• C. Opening the door of the patient’s room leading into the hospital corridor
• D. Failing to wear gloves when administering a bed bath

Correct answer: D

Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.
