Which of the following is a characteristic of a Venturi mask?

Reduces rebreathing of exhaled air.

Delivers high percentages of oxygen at flow rates of 10 to 15 L/min.

Provides a precise amount of oxygen.

Works independently of client breathing factors and flow of oxygen.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Reducing rebreathing of exhaled air is not a primary characteristic of a Venturi mask. This feature is more associated with non-rebreather masks, which have a one-way valve to prevent exhaled air from being inhaled again.

Choice B reason:

Delivering high percentages of oxygen at flow rates of 10 to 15 L/min is not specific to Venturi masks. Non-rebreather masks are typically used for high oxygen flow rates. Venturi masks are designed to deliver precise oxygen concentrations at lower flow rates.

Choice C reason:

Providing a precise amount of oxygen is the key characteristic of a Venturi mask. Venturi masks are equipped with color-coded adapters that allow for the delivery of specific oxygen concentrations, regardless of the patient’s breathing pattern.

Choice D reason:

Working independently of client breathing factors and flow of oxygen is not entirely accurate. While Venturi masks do provide a consistent oxygen concentration, they still depend on the flow of oxygen set by the healthcare provider.

Correct Answer is B

Explanation

Choice A reason: Suctioning the client at least every two hours is not typically necessary for a non-productive cough. Suctioning is more appropriate for patients with excessive secretions that they cannot clear on their own. Overuse of suctioning can cause irritation and discomfort.

Choice B reason: Encouraging fluids up to 3000 mL/day unless contraindicated is crucial for a client with pneumonia. Adequate hydration helps to thin mucus, making it easier to expectorate and clear from the lungs. This can improve the client’s ability to cough effectively and reduce the risk of complications such as atelectasis. Hydration also supports overall bodily functions and helps in maintaining electrolyte balance.

Choice C reason: Encouraging a right side-lying position is not the best intervention for a client with right lower lobe pneumonia. This position may not promote optimal lung expansion and drainage. Instead, positioning the client to maximize lung expansion and facilitate drainage, such as sitting up or lying on the unaffected side, is more beneficial.

Choice D reason: Administering codeine elixir PRN following prescription is not the priority intervention. While codeine can help suppress a cough, it is generally not recommended for a non-productive cough in pneumonia because it can suppress the cough reflex needed to clear secretions. Additionally, codeine can cause respiratory depression and other side effects.

A. Albuterol nebulizer 2.5 mg q 4 hours B. Guaifenesin 1200 mg PO q 12 hours C. Methylprednisolone 40 mg IV q 12 hours D. Dextromethorphan 60 mg PO q 12 hours

Correct Answer is D

Explanation

Choice A reason: Albuterol is a bronchodilator that helps to open up the airways, making it easier to breathe. It is commonly used in the treatment of acute bronchitis, especially if the patient is experiencing wheezing or shortness of breath. Albuterol works by relaxing the muscles around the airways, which helps to relieve symptoms of bronchospasm.

Choice B reason: Guaifenesin is an expectorant that helps to thin and loosen mucus in the airways, making it easier to cough up and clear out. This can be particularly helpful for a patient with a productive cough and green sputum, as it aids in clearing the respiratory passages. Guaifenesin is often used in the management of acute bronchitis to help alleviate symptoms.

Choice C reason: Methylprednisolone is a corticosteroid that helps to reduce inflammation in the airways. It can be beneficial in severe cases of acute bronchitis where there is significant inflammation and swelling of the bronchial tubes. Corticosteroids like methylprednisolone are used to decrease the inflammatory response and improve breathing.

Choice D reason: Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. However, in the case of acute bronchitis with a productive cough, suppressing the cough can be counterproductive. The goal is to clear the mucus from the airways, and suppressing the cough can lead to mucus retention and potentially worsen the condition. Therefore, the use of a cough suppressant like dextromethorphan is not recommended in this scenario.
