Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. A client has unilateral paralysis and dysphagia following a right hemispheric stroke. Which of the following interventions should the nurse include in the plan?

• A. Place the client's left arm on a pillow while he is sitting.
• B. Provide total care in assisting with the client's ADLs.
• C. Encourage mobility and avoid bed rest.
• D. Facilitate feeding by placing food on the left side of the client's mouth when ready to eat.

Correct answer: A

Rationale: Placing the client's left arm on a pillow while sitting helps prevent shoulder displacement and assists in maintaining proper positioning and alignment. This intervention is crucial to prevent complications associated with immobility. Providing total care in ADLs may hinder the client's independence and recovery. Encouraging mobility is essential in preventing complications of immobility. Facilitating feeding by placing food on the unaffected side of the mouth helps reduce the risk of aspiration in clients with dysphagia.

3. A client is being educated by a healthcare provider on the purpose of taking a bronchodilator. Which of the following client statements indicates an understanding of the teaching?

• A. ''This medication can decrease my immune response.''
• B. ''I take this medication to prevent asthma attacks.''
• C. ''I need to take this medication with food.''
• D. ''This medication has a slow onset to treat my symptoms.''

Correct answer: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.

4. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. Which of the following is the correct meaning of CBR?

• A. Cardiac Board Room
• B. Complete Bathroom
• C. Complete Bed Rest
• D. Complete Board Room

Correct answer: C

Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.
