1. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?

• A. ''This action of my lips helps to keep my airway open.''
• B. ''I can expel more air when I pucker up my lips to breathe out.''
• C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
• D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''

Correct answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

2. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?

• A. PT/INR
• B. CBC
• C. PTT
• D. WBC

Correct answer: A

Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.

3. What does preload refer to?

• A. The volume of blood entering the left side of the heart
• B. The volume of blood entering the right side of the heart
• C. The pressure in the venous system that the heart must overcome to pump the blood
• D. The pressure in the arterial system that the heart must overcome to pump the blood

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

4. A small fire has erupted in a wastebasket in the client waiting room. Which of the following is the first action of the nurse?

• A. Call 9-1-1
• B. Find the fire extinguisher
• C. Move clients to safety
• D. Throw water on the fire

Correct answer: C

Rationale: When a fire starts in a healthcare setting, the first action of the nurse is to move clients and anyone who may be in danger to a safe location. Ensuring the safety of clients is the top priority during emergencies. While using a fire extinguisher could be a subsequent step to contain the fire, the immediate focus should be on evacuating individuals from harm's way. Calling 9-1-1 is important, but moving clients to safety should be the nurse's initial response. Throwing water on the fire may not be effective or safe, as it can exacerbate some types of fires.

5. A client with expressive aphasia is pointing wildly at the bath water but unable to speak. Which response from the nurse is most appropriate?

• A. Is something wrong with the bath water?
• B. Just calm down, we'll finish your bath soon.
• C. Are you trying to tell me something?
• D. Shall I turn on the television?

Correct answer: A

Rationale: A client with expressive aphasia faces difficulty expressing themselves verbally but can understand others. In this scenario, the client's gestures indicate a communication attempt. The nurse's best response is to directly address the potential issue the client is indicating, which is the bath water. Option A acknowledges the client's non-verbal communication and seeks to address their concern. Choices B, C, and D do not directly address the client's attempt to communicate about the bath water, which is the focal point of the interaction.
