Nursing Elites

1. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?

• A. Increase the oxygen flow rate if shortness of breath occurs
• B. Use oxygen only when experiencing shortness of breath
• C. Do not adjust the oxygen flow rate without consulting a healthcare provider
• D. Use a humidifier with the oxygen to prevent dry mucous membranes

Correct answer: C

Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.

2. Which membrane lines the abdominal cavity?

• A. Perineum
• B. Pericardium
• C. Pleura
• D. Peritoneum

Correct answer: D

Rationale: The correct answer is D, Peritoneum. The peritoneum is the membrane that lines the abdominal cavity, providing support to abdominal organs and serving as a conduit for their blood vessels. Choices A, B, and C are incorrect. The perineum refers to the area between the anus and the external genitalia, the pericardium is the membrane enclosing the heart, and the pleura is the membrane surrounding the lungs.

3. A client with a history of pulmonary embolism is on anticoagulant therapy. What should the nurse monitor regularly?

• A. International Normalized Ratio (INR)
• B. Blood glucose levels
• C. Blood pressure
• D. Temperature

Correct answer: A

Rationale: Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.

4. When caring for a client with a tracheostomy, what is the most important assessment to perform?

• A. Check the client's oxygen saturation
• B. Assess the tracheostomy site for signs of infection
• C. Monitor the client's respiratory rate
• D. Ensure the tracheostomy ties are secure

Correct answer: A

Rationale: The most important assessment to perform when caring for a client with a tracheostomy is to check the client's oxygen saturation. This assessment is crucial as it ensures that the client is receiving adequate oxygen through the tracheostomy. Monitoring oxygen saturation provides immediate information on the client's respiratory status and the effectiveness of the airway management. Assessing the tracheostomy site for signs of infection is important but not as critical as ensuring adequate oxygenation. Monitoring the respiratory rate is also essential but does not directly assess the effectiveness of oxygenation. Ensuring tracheostomy ties are secure is important for maintaining the device but does not directly evaluate the client's oxygenation status.

5. Which structures are located in the subcutaneous layer of the skin?

• A. Sebaceous and sweat glands
• B. Melanin and keratin
• C. Sensory receptors and hair follicles
• D. Adipose cells and blood vessels

Correct answer: D

Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
