A patient was admitted to the intensive care unit 48 hours ago for treatment of a gunshot wound. The patient has recently developed a productive cough and a temperature of 39°C. The patient is breathing on their own and doesn’t require mechanical ventilation. On assessment, you note coarse crackles in the right lower lobe. A chest x-ray shows infiltrates with consolidation in the right lower lobe. Based on this specific patient scenario, this is known as what type of pneumonia?

A patient has been hospitalized with tuberculosis (TB). The patient’s friend is fearful of entering the room where the patient is in isolation and refuses to visit. What action by the nurse is best?

A nurse is preparing to administer naproxen 250 mg PO every six hours for a client who has otitis media. The amount available is naproxen 125 mg/5 mL oral suspension. How many mL should the nurse administer per dose? Do not provide the unit of measurement.  Round the answer to the nearest whole number.

 A nurse is caring for a toddler who has acute otitis media. Which of the following is the priority action for the nurse to take?

A patient is admitted with suspected pneumonia from the emergency department. The patient went to the primary care provider a “few days ago” and shows the nurse the results of what the patient calls “an allergy test,” as shown below:What action by the nurse takes priority?

The size of air ducts is dependent upon many factors including:

In HVAC duct system design, ___________ refers to the amount of straight duct that would generate the same amount of resistance to airflow (i.e., pressure drop) as a fitting, such as an elbow, tee, or transition. HVAC systems typically have both straight sections and various fittings, and while straight ducts have predictable resistance based on length and diameter, fittings can introduce additional friction and turbulence, increasing the pressure drop.

______ refers to the reduction in air pressure that occurs as air flows through an HVAC system, such as ducts, filters, or coils.

Duct Sizing – Equal Friction Method The airflow rate in a section of duct is 2000 cfm. The static pressure drop is 0.20” WC. Find the size (diameter) of the duct using the equal friction method. A copy of the equal friction chart is provided for convenience.

Air throw is defined as what?
