Which clinical manifestation is most reflective of an early response to hypoxia?

Restlessness

Cyanosis

Apnea

Bradycardia

Answer and Explanation

The Correct Answer is A

Choice A Reason:

Restlessness is often one of the earliest signs of hypoxia. When the body experiences low oxygen levels, the brain is one of the first organs to be affected. This can lead to symptoms such as anxiety, agitation, and restlessness as the brain struggles to function properly without adequate oxygen. These symptoms occur because the body is trying to compensate for the lack of oxygen by increasing respiratory and heart rates, which can make a person feel uneasy or restless.

Choice B Reason:

Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood. While cyanosis is a significant indicator of hypoxia, it is typically a later sign. By the time cyanosis is visible, hypoxia has usually been present for some time, and oxygen levels have been critically low. Therefore, it is not the earliest clinical manifestation of hypoxia.

Choice C Reason:

Apnea is the absence of breathing. This is a severe and late sign of hypoxia. When a person stops breathing, it indicates that the body has been deprived of oxygen for an extended period, leading to critical conditions. Apnea is a medical emergency and requires immediate intervention, but it is not an early sign of hypoxia.

Choice D Reason:

Bradycardia is a slower than normal heart rate. Like apnea, bradycardia is a late sign of hypoxia. Initially, the body responds to low oxygen levels by increasing the heart rate (tachycardia) to pump more oxygenated blood to tissues. Bradycardia occurs when the body can no longer compensate, and the heart rate slows down, indicating severe hypoxia and impending failure of the cardiovascular system.

Correct Answer is C

Explanation

Choice A Reason:

A pureed diet consists of foods that are blended to a smooth consistency. This type of diet is typically recommended for clients who have severe swallowing difficulties or are at risk of aspiration. While it can be easier to consume for those with significant dental issues, it may not provide the variety and texture that a mechanical soft diet offers, which can be more satisfying and nutritionally adequate for someone with multiple cavities and missing teeth.

Choice B Reason:

A soft diet includes foods that are easy to chew and swallow but are not necessarily blended or pureed. This diet is often recommended for clients recovering from surgery or those with mild chewing difficulties. However, for a client with multiple cavities, chipped, and missing teeth, a soft diet might still pose challenges in terms of chewing and could lead to discomfort or inadequate nutrition.

Choice C Reason:

A mechanical soft diet is specifically designed for individuals who have difficulty chewing but do not require pureed foods. This diet includes foods that are easy to chew and swallow, such as ground meats, cooked vegetables, and soft fruits. It provides a balance of texture and nutrition, making it the most appropriate choice for a client with multiple cavities, chipped, and missing teeth. This diet helps ensure the client can eat comfortably and maintain adequate nutrition.

A. Metabolic acidosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic alkalosis

Correct Answer is B

Explanation

Choice A reason: Metabolic acidosis is characterized by a decrease in blood pH due to an accumulation of acids or a loss of bicarbonate. It can result from conditions such as diabetic ketoacidosis, renal failure, or severe diarrhea. However, it is not typically associated with opioid overdose. Opioid overdose primarily affects the respiratory system, leading to hypoventilation and respiratory acidosis.

Choice B reason: Respiratory acidosis occurs when there is an accumulation of carbon dioxide (CO2) in the blood due to hypoventilation. Opioid overdose depresses the central nervous system, leading to decreased respiratory rate and depth, which causes CO2 retention. This results in a decrease in blood pH, leading to respiratory acidosis. Symptoms may include confusion, lethargy, and shortness of breath.

Choice C reason: Respiratory alkalosis is characterized by a decrease in blood CO2 levels due to hyperventilation. It can occur in conditions such as anxiety, fever, or high altitude. Opioid overdose, however, causes hypoventilation rather than hyperventilation, making respiratory alkalosis an unlikely outcome.

Choice D reason: Metabolic alkalosis is characterized by an increase in blood pH due to an accumulation of bicarbonate or a loss of acids. It can result from conditions such as prolonged vomiting, diuretic use, or excessive bicarbonate intake. Opioid overdose does not typically lead to metabolic alkalosis. The primary concern with opioid overdose is respiratory depression and the resulting respiratory acidosis.
