A nurse is caring for a client who is receiving oxygen therapy via a nasal cannula. The nurse explains to the client that this method of oxygen delivery does which of the following?

Restricts the client's ability to eat, speak, or drink

Delivers a constant rate of a specific concentration of oxygen

Delivers a high concentration of oxygen

Delivers a low concentration of oxygen

Answer and Explanation

The Correct Answer is D

A reason:

Restricting the client's ability to eat, speak, or drink is incorrect. A nasal cannula is designed to allow clients to eat, speak, and drink comfortably while receiving oxygen therapy.

B reason:

Delivering a constant rate of a specific concentration of oxygen is somewhat accurate but incomplete. The concentration can vary based on the flow rate set by the healthcare provider.

C reason:

Delivering a high concentration of oxygen is incorrect. Nasal cannulas typically provide low to moderate concentrations of oxygen, depending on the flow rate (usually 1-6 liters per minute).

D reason:

Delivering a low concentration of oxygen is correct. Nasal cannulas are used to provide supplemental oxygen at low flow rates, suitable for clients who require minimal assistance with their oxygen levels.

Correct Answer is C

Explanation

A reason:

Decreased heart rate is not a manifestation of hypovolemia. In fact, hypovolemia typically causes an increased heart rate (tachycardia) as the body attempts to compensate for the reduced blood volume.

B reason:

Increased blood pressure is not a characteristic of hypovolemia. Hypovolemia usually results in decreased blood pressure (hypotension) due to the reduced volume of blood circulating in the body.

C reason:

A weak pulse is a common manifestation of hypovolemia. Due to the reduced blood volume, the heart may not be able to generate a strong pulse, resulting in a weak and thready pulse.

D reason:

Dyspnea, or difficulty breathing, can be associated with hypovolemia but it is not as direct a manifestation as a weak pulse. It may occur due to inadequate oxygen delivery to tissues or related conditions, but the primary signs of hypovolemia are related to blood pressure and pulse.

A. Ignoring the urge to defecate B. Inadequate fluid intake C. Decreased fiber in the diet D. Increased activity E. Excessive laxative use

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

Explanation

A reason:

Ignoring the urge to defecate is a common cause of constipation. Suppressing the natural urge can lead to harder stools and decreased bowel movement regularity.

B reason:

Inadequate fluid intake contributes to constipation by leading to harder stools that are more difficult to pass. Sufficient hydration is essential for maintaining regular bowel movements.

C reason:

Decreased fiber in the diet is a significant cause of constipation. Fiber helps to bulk up the stool and promote regular bowel movements. A diet low in fiber can result in harder and less frequent stools.

D reason:

Increased activity typically promotes regular bowel movements and is not a cause of constipation. Physical activity stimulates intestinal motility, helping to prevent constipation.

E reason:

Excessive laxative use can lead to dependence and decreased bowel motility over time, causing constipation. Overuse of laxatives can disrupt the natural bowel rhythm and lead to chronic constipation.
