A nurse is preparing to administer amoxicillin 2 g/day PO divided into two doses. The amount available is amoxicillin 500 mg tablets.

How many tablets should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:

Losing weight is one of the most effective ways to reduce the severity of obstructive sleep apnea (OSA). Excess weight, especially around the neck, can increase the risk of airway obstruction during sleep. Studies have shown that losing even 5-10% of body weight can significantly improve OSA symptoms. Therefore, the statement about losing 50 pounds indicates a good understanding of how weight loss can help manage sleep apnea.

Choice B Reason:

Taking a sleeping pill at night is not recommended for individuals with obstructive sleep apnea. Many sleeping pills, especially those that are sedatives or muscle relaxants, can worsen sleep apnea by relaxing the muscles of the throat, leading to increased airway obstruction. Therefore, this statement does not indicate an understanding of the appropriate management of sleep apnea.

Choice C Reason:

Using a humidifier can help alleviate some symptoms associated with sleep apnea, such as dry mouth and nasal congestion, but it does not directly reduce the number of apneic episodes. While a humidifier can improve comfort, it is not a primary treatment for reducing apneic episodes in OSA patients.

Choice D Reason:

Sleeping on the back is generally not recommended for individuals with obstructive sleep apnea. This position can cause the tongue and soft tissues to collapse to the back of the throat, worsening airway obstruction. Side sleeping is usually recommended to help keep the airway open. Therefore, this statement does not indicate an understanding of the best sleep practices for managing sleep apnea.

Choice A reason: While chest physiotherapy can help mobilize secretions, it does not specifically promote the flow of secretions to the base of the lungs. The primary goal is to loosen and mobilize secretions so they can be coughed up and cleared from the airways. This helps improve overall lung function and oxygenation.

Choice B reason: Chest physiotherapy does not eliminate the need to cough. In fact, coughing is an essential part of the process as it helps expel the loosened secretions from the airways. The therapy aims to make coughing more effective by loosening the mucus.

Choice C reason: The primary purpose of chest physiotherapy with percussion and vibration is to help clear the airways of excessive secretions. This is particularly important for patients with conditions like chronic obstructive pulmonary disease (COPD), cystic fibrosis, or pneumonia, where mucus buildup can obstruct the airways and impair breathing. By loosening and mobilizing the secretions, the therapy facilitates their removal through coughing.

Choice D reason: Chest physiotherapy does not limit the production of bronchial mucus. It focuses on clearing existing mucus from the airways rather than reducing its production. The production of mucus is influenced by underlying conditions and may require other treatments to manage.
