A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococcal infection.
Available is clindamycin 900 mg in 50 mL. How many mL/hr should the nurse set the IV pump to? (Round to the nearest whole number, use a leading zero if it applies, do not use a trailing zero)

Choice A rationale:
History of rheumatologic conditions: Research has demonstrated a link between fibromyalgia and other rheumatologic conditions, such as rheumatoid arthritis, lupus, and osteoarthritis. Individuals with these conditions may have a predisposition to developing fibromyalgia due to shared genetic factors, immune system dysregulation, and chronic inflammation.
Choice B rationale:
Nutritional deficiency: While nutritional deficiencies, particularly in vitamin D, magnesium, and iron, have been associated with fibromyalgia symptoms, there's not enough evidence to establish them as direct risk factors for its development.
Nutritional deficiencies can worsen pain and fatigue, but they aren't considered primary causes of fibromyalgia.
Choice C rationale:

Previous injury to the bone: Past bone injuries typically aren't considered a risk factor for fibromyalgia. Fibromyalgia is a chronic pain syndrome that affects muscles and soft tissues, not bones themselves. While pain from an injury might trigger fibromyalgia symptoms, it's not a direct cause.
Choice D rationale:
Deep sleep deprivation: Sleep disturbances, especially disruptions in deep sleep (also known as slow-wave sleep), are strongly linked to fibromyalgia. Deep sleep is crucial for restorative processes in the body, including pain regulation. Insufficient deep sleep can lead to heightened pain sensitivity and contribute to the development of fibromyalgia.
Choice E rationale:
Physical and emotional trauma: Physical and emotional trauma, such as experiencing accidents, abuse, or significant psychological stress, can significantly increase the risk of developing fibromyalgia. Trauma can trigger changes in the brain's pain processing pathways and stress hormone regulation, contributing to chronic pain and other fibromyalgia symptoms.

Choice A rationale:
Coughing and deep breathing are essential for mobilizing and removing secretions from the airways, which is crucial for improving airway clearance in patients with pneumonia. These techniques help to loosen mucus and bring it up from the lungs, allowing it to be expelled through coughing.
Hydration maintenance is also critical because it helps to thin secretions, making them easier to cough up. Adequate hydration helps to keep mucus moist and less sticky, which promotes easier expectoration.
Choice B rationale:
Keeping the head of the bed elevated can help to improve oxygenation and reduce the work of breathing, but it does not directly address the issue of airway clearance. It may be a helpful adjunct intervention, but it's not the priority for this specific nursing diagnosis.
Choice C rationale:
Preparation for insertion of a tracheostomy tube is a more invasive intervention that may be necessary in severe cases of airway obstruction, but it is not the first-line intervention for ineffective airway clearance related to pneumonia. It would be considered if other measures fail to maintain adequate ventilation.

Choice D rationale:
Providing supplemental oxygen can help to improve oxygenation in patients with pneumonia, but it does not directly address the issue of airway clearance. It's important to support oxygenation, but it's not the primary intervention to clear secretions.
