A nurse is providing education about insulin management to a client newly diagnosed with type 1 diabetes mellitus. Which of the following statements by the nurse about injection site selection is accurate?
Injections will work most quickly when given in the thigh.
Injections will work most quickly when given in the upper arm.
Injections will work most quickly when given in the buttocks.
Injections will work most quickly when given in the abdomen.
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 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.
Correct Answer is B
Explanation
Choice A reason: Decreased Body Temperature
Decreased body temperature is not typically associated with hyperthyroidism. In fact, hyperthyroidism often causes an increase in body temperature due to the accelerated metabolic rate. Patients with hyperthyroidism may experience heat intolerance and excessive sweating, but not a decrease in body temperature.
Choice B reason: Tachycardia
Tachycardia, or an abnormally fast heart rate, is a common symptom of hyperthyroidism. The elevated levels of thyroid hormones (T4 and T3) increase the body’s metabolism, leading to an increased heart rate. This can result in palpitations and a feeling of a racing heart, which are characteristic signs of hyperthyroidism. Therefore, tachycardia is the most likely vital sign abnormality in this scenario.
Choice C reason: Hypotension
Hypotension, or low blood pressure, is not typically associated with hyperthyroidism. Instead, hyperthyroidism can sometimes cause an increase in blood pressure due to the heightened metabolic activity and increased cardiac output4. Therefore, hypotension is not a characteristic finding in patients with elevated thyroid hormone levels.
Choice D reason: Slow Respiratory Rate
A slow respiratory rate is not commonly seen in hyperthyroidism. The condition usually leads to an increased respiratory rate due to the body’s heightened metabolic demands. Patients with hyperthyroidism may experience shortness of breath and rapid breathing, but not a slow respiratory rate.
