1. Which surgical procedure involves removing a portion of the lung?

• A. Lobectomy
• B. Pneumonectomy
• C. Tracheostomy
• D. Bronchoscopy

Correct answer: A

Rationale: A lobectomy is the surgical removal of a lobe of the lung. This procedure is commonly performed to treat conditions like lung cancer or severe lung diseases. Pneumonectomy involves removing an entire lung, making it incorrect. Tracheostomy is a surgical procedure to create an opening in the windpipe, not involving lung tissue removal. Bronchoscopy is a diagnostic procedure that allows visualization of the airways using a thin, flexible tube with a camera, not involving lung tissue removal.

2. What is the ability of cardiac cells to respond to an impulse by transmitting the impulse along cell membranes?

• A. Contractility
• B. Automaticity
• C. Conductivity
• D. Rhythmicity

Correct answer: C

Rationale: The correct answer is C, Conductivity. Conductivity refers to the ability of cardiac cells to transmit impulses along cell membranes. Contractility (Choice A) is the ability of cardiac cells to contract in response to an electrical stimulus, not transmit impulses. Automaticity (Choice B) is the ability of cardiac cells to spontaneously generate electrical impulses. Rhythmicity (Choice D) refers to the regular generation of electrical impulses by the heart's pacemaker cells, not the transmission of impulses along cell membranes.

3. What is a condition where the arteries supplying blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

• A. Peripheral artery disease
• B. Atherosclerosis
• C. Varicose veins
• D. Raynaud's disease

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is characterized by the narrowing or blockage of arteries that supply blood to the legs and feet, resulting in pain and difficulty walking. Choice B, Atherosclerosis, is a condition involving the buildup of plaque in the arteries but is not specific to the legs and feet. Varicose veins (Choice C) refer to enlarged, twisted veins usually occurring in the legs. Raynaud's disease (Choice D) involves episodes of reduced blood flow to the extremities, typically triggered by cold temperatures or stress, but it is not directly related to the arteries in the legs and feet.

4. What is a surgical procedure to create an opening in the windpipe to assist with breathing?

• A. Tracheostomy
• B. Lobectomy
• C. Thoracotomy
• D. Pleurodesis

Correct answer: A

Rationale: Tracheostomy is the correct answer. It is a surgical procedure to create an opening in the windpipe (trachea) to assist with breathing. This procedure is commonly used for patients who require long-term ventilation support. Choice B, Lobectomy, involves the removal of a lobe of the lung and is not related to creating an opening in the windpipe. Choice C, Thoracotomy, is a surgical incision into the chest wall and is not specifically related to creating an opening in the windpipe. Choice D, Pleurodesis, is a procedure to treat recurrent pleural effusions by causing the pleural layers to stick together, and it is not related to creating an opening in the windpipe.

5. The client on amiodarone develops symptoms of hypothyroidism. What is the nurse’s best response?

• A. Notify the healthcare provider immediately.
• B. Reassure the client that this is a common side effect of amiodarone.
• C. Monitor the client’s thyroid function tests regularly.
• D. Discontinue the amiodarone immediately.

Correct answer: C

Rationale: When a client on amiodarone develops symptoms of hypothyroidism, the nurse's best response is to monitor the client's thyroid function tests regularly. Amiodarone can affect thyroid function, so monitoring is essential to assess the impact and adjust treatment if necessary. Notifying the healthcare provider immediately (Choice A) may be necessary in some cases but the priority is to monitor first. Reassuring the client (Choice B) is not sufficient as monitoring is crucial. Discontinuing amiodarone (Choice D) abruptly without healthcare provider guidance can lead to serious consequences.
