In the emergency department, a nurse is assessing a client involved in a motor vehicle crash. Findings include absent breath sounds in the left lower lobe with dyspnea, blood pressure 118/68 mm Hg, heart rate 124/min, respirations 38/min, temperature 38.6 C (101.4 F), and SaO2 92% on room air. What action should the nurse take first?

A. Obtain a chest X-ray.

B. Prepare for chest tube insertion.

C. Administer oxygen via high-flow mask.

D. Initiate IV access.

Correct Answer: C: Administer oxygen via high-flow mask.
Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

A client has global aphasia affecting both receptive and expressive language abilities. Which intervention should NOT be included in the client's care plan?

• A. Speak to the client at a slower rate.
• B. Assist the client in using flash cards with pictures.
• C. Speak to the client in a loud voice.
• D. Give instructions one step at a time.

Correct Answer: C: Speak to the client in a loud voice.
Rationale: Individuals with global aphasia have difficulty understanding and expressing language. Speaking loudly may not improve comprehension and can be perceived as aggressive. Therefore, it is important not to speak loudly to a client with global aphasia. Speaking at a slower rate, using visual aids like flash cards, and breaking down instructions into simple steps can facilitate communication and understanding for the client.

A client has experienced a right-hemispheric stroke. Which of the following is not an expected finding?

• A. Impulse control difficulty
• B. Left hemiplegia
• C. Loss of depth perception
• D. Aphasia

Correct Answer: Aphasia
Rationale: In a right-hemispheric stroke, the expected findings include left-sided hemiplegia (Choice B), loss of depth perception (Choice C), and impulse control difficulty (Choice A). Aphasia (Choice D) is typically associated with left-hemispheric strokes. Therefore, aphasia is not an expected finding in a client who has experienced a right-hemispheric stroke.

When is the most appropriate time for obtaining a sputum specimen for culture?

• A. Early in the morning
• B. After the patient eats a light breakfast
• C. After aerosol therapy
• D. After chest physiotherapy

Correct Answer: A
Rationale: Obtaining a sputum specimen early in the morning is the most appropriate time because secretions have accumulated overnight. This timing provides the best sample with the least contamination, leading to more accurate culture results and aiding in diagnosing respiratory infections effectively.

A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

• A. I can substitute one medication for another if I run out because they all fight infection.
• B. I will wash my hands each time I cough.
• C. I am glad I don't have to have any more sputum specimens.
• D. I don't need to worry about where I go once I start taking my medications.

Correct Answer: B
Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.
