The practical nurse (PN) is preparing to assist an elderly client to the bathroom. The PN knows that an elderly adult's center of gravity changes from the hips to another area of the body. While planning to safely assist this client, the PN knows that the center of gravity for the elderly client is in which area of the body?

Upper torso.

Feet.

Upper extremities.

Head.

Answer and Explanation

The Correct Answer is A

A. The upper torso is where the center of gravity shifts in elderly adults. As people age, their center of gravity moves higher due to changes in body composition and muscle strength, which can affect balance.
B. The feet are the base of support, not the center of gravity. The center of gravity is located higher up in the body.
C. The upper extremities do not represent the center of gravity. The shift in the center of gravity affects overall balance and stability.
D. The head does not represent the center of gravity; it is primarily located in the upper torso. The head's position influences balance but is not the center of gravity.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}

Explanation

Response 1

A. Fluid volume deficit
The client has signs of dehydration such as dry mucous membranes and a recent history of not having much to eat or drink in the past 2 days, which indicates a fluid volume deficit.

B. Respiratory alkalosis
There is no evidence to support respiratory alkalosis. The client's primary issues are related to infection and dehydration.

C. Hypoxia
The client’s oxygen saturation is 100% on 2 L/minute nasal cannula, so hypoxia is not a current issue.

D. Diarrhea
Diarrhea is not mentioned in the history, symptoms, or findings. It is not relevant to the client's condition.

Response 2

A. Decreased fluid intake
The client has not had much to eat or drink in the past 2 days, contributing directly to the fluid volume deficit.

B. Increased respiratory rate
While the client has an increased respiratory rate, it is a symptom of pneumonia rather than a cause of fluid volume deficit.

C. Infection
Although the client has pneumonia, the fluid volume deficit is more directly related to decreased fluid intake than to infection.

D. Heart disease
Heart disease is not mentioned and is not relevant to the client’s current presentation.

A. Oxygen concentration of the ambient air B. Temperature of water C. The weight of the child D. The amount of time the child was submerged E. Whether or not anyone witnessed the fall into the pool

Correct Answer is ["A","B","D","E"]

Explanation

A. Oxygen Concentration of the Ambient Air
The oxygen concentration of the ambient air affects how much oxygen the child could have been exposed to once retrieved from the pool. If the child was submerged in water, the ability to access oxygen from the environment was compromised, which contributes to the level of hypoxemia experienced. Ambient air oxygen concentration is a crucial factor in determining how long it might take for hypoxemia to develop or improve after submersion.
B. Temperature of Water
The temperature of the water affects the child’s physiology during submersion. Cold water can lead to a more rapid decrease in core body temperature and can influence the child’s respiratory and cardiovascular responses, potentially affecting the degree of hypoxemia.
C. The Weight of the Child
The weight of the child does not significantly impact the level of hypoxemia experienced during submersion. While it might influence the child’s ability to stay afloat or the rescue process, it does not directly affect hypoxemia levels.
D. The Amount of Time the Child Was Submerged
The duration of submersion is a critical factor in determining the level of hypoxemia. Longer submersion times result in more significant oxygen deprivation and a greater degree of hypoxemia, which can impact the severity of respiratory and cardiac complications.
E. Whether or Not Anyone Witnessed the Fall into the Pool
While witnessing the fall might be relevant for understanding the context of the incident, it does not directly affect the level of hypoxemia experienced during the submersion. The key factors are related to the conditions and duration of the submersion itself
