A nurse is reviewing the arterial blood gas values for a client. The nurse should recognize that the values indicate which of the following acid-base imbalances?

The values are:

• pH: 7.56
• PaCO2: 55 mmHg
• HCO3: 33 mEq/L

Normal ranges:

• pH: 7.35-7.45
• PaCO2: 35-45 mmHg
• HCO3: 22-28 mEq/L

 

Choice A Reason:

“Do not take the medication before bedtime” is incorrect because the timing of medication administration depends on the specific medication and its intended effects. Some medications are specifically prescribed to be taken at bedtime to help with sleep or to reduce side effects that might occur during the day.

Choice B Reason:

“Take the medication with a full glass of water” is correct because many medications require adequate hydration to ensure proper absorption and to prevent irritation of the esophagus and stomach. Taking medication with a full glass of water helps to ensure that the medication reaches the stomach quickly and reduces the risk of esophageal irritation or damage.

Choice C Reason:

“This medication must be taken on an empty stomach” is incorrect unless the specific medication requires it. Some medications are better absorbed on an empty stomach, but this is not a universal rule and depends on the medication’s formulation and intended use.

Choice D Reason:

“Expect abdominal pain with this medication” is incorrect because not all medications cause abdominal pain. If a medication is known to cause abdominal pain, the nurse should provide additional instructions on how to manage this side effect or discuss alternative medications with the healthcare provider.

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.
