A nurse is providing education to a client who has hypoglycemia. Which of the following information should the nurse include about the regulation of blood glucose levels?
The adrenal glands release epinephrine and norepinephrine to respond to low blood glucose.
The liver releases glucagon to regulate blood glucose levels.
Glycogenesis occurs in the pancreas when blood glucose levels fall.
The brain uses protein for energy if glucose levels fall too low.
The Correct Answer is A
Choice A Reason:
The adrenal glands play a crucial role in responding to low blood glucose levels by releasing epinephrine (adrenaline) and norepinephrine. These hormones help to increase blood glucose levels by stimulating glycogenolysis (the breakdown of glycogen to glucose) and gluconeogenesis (the production of glucose from non-carbohydrate sources) in the liver. This response is part of the body’s fight-or-flight mechanism, which ensures that sufficient glucose is available for immediate energy needs.
Choice B Reason:
The liver does not release glucagon; rather, it responds to glucagon, which is released by the pancreas. Glucagon stimulates the liver to convert stored glycogen into glucose (glycogenolysis) and to produce glucose from non-carbohydrate sources (gluconeogenesis). This process helps to raise blood glucose levels when they are low.
Choice C Reason:
Glycogenesis is the process of converting glucose into glycogen for storage, and it occurs primarily in the liver and muscle cells, not in the pancreas. The pancreas releases insulin to promote glycogenesis when blood glucose levels are high, but it does not perform glycogenesis itself.
Choice D Reason:
The brain primarily uses glucose for energy and does not switch to using protein unless glucose levels are extremely low and prolonged. In such cases, the brain can use ketone bodies derived from fat as an alternative energy source. Protein is not a primary energy source for the brain under normal conditions.

Correct Answer is D
Explanation
Choice A reason:
Injections in the thigh are absorbed more slowly compared to the abdomen. The thigh is a common site for insulin injections, but it does not provide the fastest absorption rate. The absorption rate can be influenced by physical activity, as exercise can increase blood flow to the muscles, potentially speeding up insulin absorption. However, under normal conditions, the thigh is not the fastest site for insulin absorption.
Choice B reason:
Injections in the upper arm have a moderate absorption rate. The upper arm is another common site for insulin injections, but it is not the fastest. The absorption rate from the upper arm is generally faster than the thigh but slower than the abdomen. This site can be convenient for injections, especially for those who find it difficult to reach other areas.
Choice C reason:
Injections in the buttocks have the slowest absorption rate among the common injection sites. The buttocks are less commonly used for insulin injections due to the slower absorption rate and the difficulty some individuals may have in administering injections in this area. The high fat content in the buttocks slows down the absorption of insulin.
Choice D reason:
Injections in the abdomen provide the fastest absorption rate for insulin. The abdomen is the preferred site for many people with diabetes because it has a large surface area and is easy to access. The insulin injected into the abdominal area is absorbed quickly into the bloodstream, making it the most effective site for rapid-acting insulin. This is particularly important for managing blood sugar levels around meal times.
Correct Answer is A
Explanation
Choice A: Dietary and Fluid Restrictions
Dietary and fluid restrictions are crucial for patients with heart failure. These restrictions help manage symptoms and prevent complications. Limiting sodium intake can reduce fluid retention, which decreases the workload on the heart. Fluid restrictions help prevent fluid overload, which can lead to worsening heart failure symptoms. Patients are often advised to monitor their weight daily to detect fluid retention early. This choice is essential for managing heart failure effectively.
Choice B: Encouraging Increased Mobility
While physical activity is generally beneficial for overall health, it must be approached cautiously in patients with heart failure. Encouraging increased mobility without proper medical guidance can lead to overexertion and exacerbate heart failure symptoms. Exercise programs for heart failure patients should be tailored and supervised by healthcare professionals to ensure safety and effectiveness. Therefore, this choice is not as immediately critical as dietary and fluid restrictions.
Choice C: Cessation of Hormonal Supplements
Hormonal supplements can have various effects on the cardiovascular system, but their cessation is not a standard recommendation for all heart failure patients. The impact of hormonal supplements depends on the specific type and the patient’s overall health condition. This choice is less relevant compared to dietary and fluid restrictions, which have a direct and significant impact on heart failure management.
Choice D: Cessation of Intravenous (IV) Drug Use
Cessation of intravenous drug use is important for overall health and preventing infections, but it is not specific to heart failure management. While IV drug use can lead to complications that may affect the heart, it is not a primary lifestyle modification recommended for heart failure patients. The focus should be on managing fluid balance and dietary intake
