The nurse is caring for a client with type 1 diabetes mellitus who has been taught the dosage of insulin.

Injections in the thigh

Injections in the upper arm

Injections in the buttocks

Injections in the abdomen

Answer and Explanation

The Correct Answer is D

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 D

Explanation

Choice A reason: Hypokalemia

Hypokalemia refers to a low level of potassium in the blood. It can cause muscle weakness, cramps, and arrhythmias, but it is not directly related to Kussmaul breathing. Hypokalemia can occur in diabetic ketoacidosis (DKA) due to the loss of potassium in urine, but it is not the primary cause of Kussmaul breathing. Kussmaul breathing is a deep, labored breathing pattern that occurs as a compensatory mechanism for metabolic acidosis, not directly due to low potassium levels.

Choice B reason: Metabolic Alkalosis

Metabolic alkalosis is a condition characterized by an elevated pH in body tissues due to an excess of bicarbonate or a loss of acid. It is the opposite of metabolic acidosis. Kussmaul breathing is specifically a response to metabolic acidosis, not alkalosis. Therefore, metabolic alkalosis is not related to Kussmaul breathing.

Choice C reason: Lipolysis

Lipolysis is the metabolic process of breaking down lipids (fats) into free fatty acids and glycerol. This process is accelerated in diabetic ketoacidosis (DKA) due to the lack of insulin, leading to the production of ketone bodies, which contribute to metabolic acidosis. While lipolysis is a part of the pathophysiology of DKA, it is not directly related to Kussmaul breathing. Kussmaul breathing is a compensatory mechanism for the acidosis caused by the accumulation of ketone bodies.

Choice D reason: Hyperglycemia

Hyperglycemia, or high blood sugar, is a hallmark of diabetic ketoacidosis (DKA). In DKA, the lack of insulin leads to elevated blood glucose levels and the breakdown of fats into ketones, causing metabolic acidosis. Kussmaul breathing is the body’s attempt to compensate for this acidosis by increasing the rate and depth of breathing to expel more carbon dioxide, thereby reducing the acidity of the blood. Therefore, hyperglycemia is directly related to the occurrence of Kussmaul breathing in DKA.

A. Coronary arteries become more elastic, causing the arteries to stretch as individuals age, leading to the heart not receiving enough oxygen. B. Coronary arteries decrease in diameter, leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. C. Coronary arteries decrease in diameter, leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. D. Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure. E. The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina.

Correct Answer is B

Explanation

Choice A Reason:

Coronary arteries do not become more elastic with age. Instead, they tend to become less elastic due to the buildup of plaque, a condition known as atherosclerosis. This buildup narrows the arteries and restricts blood flow, which can lead to coronary artery disease (CAD). The heart not receiving enough oxygen is a result of this narrowing, not increased elasticity.

Choice B Reason:

Coronary arteries decrease in diameter due to the buildup of plaque, which consists of fats, cholesterol, and other substances. This narrowing restricts the flow of blood, oxygen, and nutrients to the heart muscle, leading to symptoms such as chest pain (angina) and shortness of breath. This is the primary mechanism behind coronary artery disease.

Choice C Reason:

This choice is essentially a repetition of Choice B and is correct for the same reasons. The narrowing of the coronary arteries due to plaque buildup leads to insufficient blood flow, causing the heart muscle to receive less oxygen and nutrients.

Choice D Reason:

Manifestations of coronary artery disease are not due to the dilation of coronary arteries. Instead, they are due to the narrowing of these arteries. Increased blood flow and pressure are not typical causes of CAD symptoms. The primary issue is the restricted blood flow due to narrowed arteries.

Choice E Reason:

While it is true that the heart and coronary arteries can weaken over time, leading to poor perfusion and angina, this statement does not accurately describe the primary mechanism of coronary artery disease. The main issue in CAD is the narrowing of the arteries due to plaque buildup, which restricts blood flow to the heart muscle.
