A nurse is teaching a client who is newly diagnosed with type 1 diabetes mellitus about insulin safety. Which of the following statements by the nurse is appropriate?
Insulin is stable at room temperature for one month.
Insulins can be mixed in the same syringe.
Storing insulin in the freezer will prolong its stability.
Clients with type 1 diabetes mellitus should keep backup medication and supplies in their car.
The Correct Answer is A
Choice A Reason:
Insulin is stable at room temperature (between 59°F and 86°F) for up to one month. This is important for patients to know, especially if they do not have immediate access to refrigeration. However, it is crucial to avoid exposing insulin to extreme temperatures, such as direct sunlight or freezing conditions, as these can degrade the medication’s effectiveness.
Choice B Reason:
While some types of insulin can be mixed in the same syringe, this practice is not universally applicable to all insulin types. For example, rapid-acting and intermediate-acting insulins can sometimes be mixed, but long-acting insulins should not be mixed with other insulins. Therefore, this statement is not entirely accurate and should be clarified based on the specific types of insulin being used.
Choice C Reason:
Storing insulin in the freezer is not recommended as freezing can damage the insulin, rendering it ineffective. Insulin should be stored in a refrigerator at temperatures between 36°F and 46°F. If insulin is accidentally frozen, it should not be used.
Choice D Reason:
While it is advisable for clients with type 1 diabetes to have backup medication and supplies, storing them in a car is not recommended due to the potential for extreme temperature fluctuations. Insulin and other diabetes supplies should be kept in a stable, controlled environment to ensure their efficacy.

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.
Correct Answer is A
Explanation
Choice A Reason:
Dietary and fluid restrictions are crucial for managing heart failure. Patients with heart failure often experience fluid retention, which can exacerbate symptoms such as swelling, shortness of breath, and fatigue. By restricting fluid intake, patients can help prevent fluid overload. Additionally, dietary modifications, such as reducing sodium intake, can help manage blood pressure and reduce the risk of fluid retention. Sodium causes the body to retain water, which can increase the workload on the heart. Therefore, a low-sodium diet is often recommended for heart failure patients. These restrictions are essential to prevent the worsening of heart failure symptoms and to improve the patient’s quality of life.
Choice B Reason:
Encouraging increased mobility is generally beneficial for overall health, but it must be approached cautiously in heart failure patients. While regular physical activity can help improve cardiovascular health and overall well-being, it is important to tailor the exercise regimen to the patient’s condition. Overexertion can lead to worsening symptoms or complications. Therefore, while increased mobility can be part of the management plan, it should be done under medical supervision and is not the primary lifestyle modification for heart failure management.
Choice C Reason:
Cessation of hormonal supplements may be relevant for some patients, particularly if the supplements are contributing to fluid retention or other adverse effects. However, this is not a standard recommendation for all heart failure patients. The decision to stop hormonal supplements would depend on the individual patient’s medical history and the specific supplements they are taking. It is not a general lifestyle modification for heart failure management.
Choice D Reason:
Cessation of intravenous (IV) drug use is important for patients who may be using IV drugs, as this can lead to infections, endocarditis, and other complications that can worsen heart failure. However, this recommendation is specific to patients with a history of IV drug use and is not a general lifestyle modification for all heart failure patients. The primary focus for most heart failure patients would be on managing fluid and dietary intake.
