Nursing Elites

1. What type of medication is used to reduce inflammation in the airways and prevent asthma attacks?

• A. Corticosteroid
• B. Bronchodilator
• C. Antihistamine
• D. Mucolytic

Correct answer: A

Rationale: The correct answer is A, Corticosteroid. Corticosteroids are medications that work by reducing inflammation in the airways, helping to prevent asthma attacks and manage chronic respiratory conditions. Bronchodilators (choice B) work by relaxing the muscles around the airways to make breathing easier, but they do not primarily target inflammation. Antihistamines (choice C) are used to treat allergic reactions and do not directly target airway inflammation. Mucolytics (choice D) help to break down and thin mucus in the airways but do not reduce inflammation.

2. What is the condition where the body's immune system attacks its tissues, causing inflammation and damage?

• A. Autoimmune disease
• B. Infectious disease
• C. Allergic reaction
• D. Degenerative disease

Correct answer: A

Rationale: The correct answer is A: Autoimmune disease. Autoimmune diseases occur when the body's immune system mistakenly attacks its own tissues, leading to inflammation and damage. This is different from infectious diseases (choice B), which are caused by pathogenic microorganisms, allergic reactions (choice C), which involve an exaggerated response of the immune system to harmless substances, and degenerative diseases (choice D), which are characterized by progressive deterioration of tissue or organs due to various factors.

3. 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.

4. What is a surgical procedure to remove one of the lobes of the lungs, often performed to treat lung cancer?

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

Correct answer: A

Rationale: A lobectomy is the correct answer. This surgical procedure involves removing one of the lobes of the lungs, commonly done to treat lung cancer or other serious lung ailments. Choice B, pneumonectomy, involves the complete removal of a lung, not just a lobe. Choice C, thoracotomy, is a surgical incision into the chest wall and is not specific to removing a lung lobe. Choice D, tracheostomy, is the creation of an opening in the windpipe to assist with breathing and is unrelated to lung lobe removal.

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.
