The nurse is caring for a client with asthma. The client asks the nurse what structures make up the upper respiratory tract. Which response by the num the most appropriate?
The nose, nasal cavity, pharynx, and paranasal sinuses
The nose and paranasal sinuses
The lungs and associated structures
The nose, nasal cavity, pharynx, and the lungs
The Correct Answer is A
A) The nose, nasal cavity, pharynx, and paranasal sinuses.
The upper respiratory tract consists of the structures located above the larynx (voice box). These include the nose, nasal cavity, pharynx (throat), and paranasal sinuses. These structures play vital roles in filtering, warming, and humidifying the air we breathe, as well as in olfaction (sense of smell) and speech resonance.
B) The nose and paranasal sinuses:
While the nose and paranasal sinuses are indeed part of the upper respiratory tract, this response does not include the entirety of the upper respiratory structures, such as the pharynx, which is also crucial.
C) The lungs and associated structures:
This choice is incorrect because the lungs are part of the lower respiratory tract, not the upper respiratory tract. The lower respiratory tract includes the trachea (windpipe), bronchi, bronchioles, and alveoli.
D) The nose, nasal cavity, pharynx, and the lungs:
This response includes structures from both the upper and lower respiratory tracts. While the nose, nasal cavity, and pharynx belong to the upper respiratory tract, the lungs are part of the lower respiratory tract. Therefore, this option is not accurate for describing the components of the upper respiratory tract.

Correct Answer is D
Explanation
A) Cardiogenic shock:
Cardiogenic shock occurs when the heart is unable to pump enough blood to meet the body's needs, often due to myocardial infarction (heart attack) or other conditions affecting the heart's function. The client's history of a recent infection does not align with the etiology of cardiogenic shock.
B) Neurogenic shock:
Neurogenic shock occurs due to dysfunction of the autonomic nervous system, typically as a result of spinal cord injury or severe brain injury. It is characterized by widespread vasodilation and bradycardia. The client's history of a recent infection does not align with the etiology of neurogenic shock.
C) Hypovolemic shock:
Hypovolemic shock occurs due to a significant loss of blood volume, such as from trauma, hemorrhage, or dehydration. While infection can lead to fluid loss and dehydration in some cases, the client's history of a recent infection suggests a different etiology, specifically septic shock, which is driven by the systemic inflammatory response to infection.
D) Septic shock.
Septic shock is a type of distributive shock caused by a systemic response to infection. It occurs when an infection triggers a widespread inflammatory response, leading to vasodilation, increased capillary permeability, fluid loss from the bloodstream, and impaired tissue perfusion. The client's history of a recent infection suggests that the shock may be septic in nature.
Correct Answer is ["5"]
Explanation
To determine how many hours it will take for the IV pump to infuse the 1000 mL bag of 0.9% sodium chloride at a rate of 200 mL/hr, we can use the following formula:
Time (hr) = Volume (mL)/Rate (mL/hr)
Given:
Volume = 1000 mL
Rate = 200 mL/hr
Substitute the given values into the formula:
Time (hr)=1000 mL/200 mL/hr
Time (hr)=5hours
Rounding to the nearest whole number, the IV pump will infuse over 5 hours.
Therefore, the nurse should expect the IV pump to infuse over 5 hours.
