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 D

Explanation

A. Administering ketorolac does not require specific timing in relation to meals. It can be given with or without food, but the key considerations are related to the drug’s effects rather than meal timing.
B. Ketorolac does not require peak and trough serum level monitoring. This practice is more relevant for medications with narrow therapeutic ranges or those requiring precise dosage adjustments, which is not the case for ketorolac.
C. Observing for involuntary movements of the lips and tongue is not a primary concern for ketorolac therapy. This is more relevant to medications like antipsychotics that can cause extrapyramidal symptoms.
D. Assessing the skin daily for signs of bleeding is crucial because ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding due to its effects on platelet function and gastrointestinal mucosa.

A. Increased oxygen saturation. B. Increased cough productivity. C. Decreased cough frequency. D. Decreased breath sounds.

Correct Answer is A

Explanation

A. Increased oxygen saturation indicates that the Venturi face mask is effectively delivering the specified concentration of oxygen. This is the primary goal of using a Venturi mask, which provides precise oxygen delivery to improve oxygen saturation levels.
B. Increased cough productivity is not a direct indicator of the effectiveness of a Venturi face mask. The mask's purpose is to deliver oxygen, not to alter cough patterns.
C. Decreased cough frequency is unrelated to the function of the Venturi face mask. The mask's effectiveness is measured by oxygen delivery rather than changes in cough frequency.
D. Decreased breath sounds are not a direct measure of the effectiveness of a Venturi face mask. Breath sounds could indicate other respiratory issues but do not specifically reflect the effectiveness of oxygen therapy.
