A nurse is caring for a client who reports increased anxiety, nervousness, heat intolerance, and unintentional weight loss. Blood testing reveals decreased thyroid-stimulating hormone (TSH), elevated thyroxine (T4), and elevated triiodothyronine (T3). Which of the following vital sign abnormalities does the nurse anticipate?
Decreased body temperature
Tachycardia
Hypotension
Slow respiratory rate
The Correct Answer is B
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: Fasting blood glucose of 140 mg/dL
A fasting blood glucose level of 140 mg/dL is above the normal range (70-99 mg/dL) but may indicate some improvement in beta cell function if it was previously higher. In type 2 diabetes, beta cells in the pancreas are responsible for producing insulin. When beta cells start to restore their function, they can produce more insulin, which helps lower blood glucose levels. However, a fasting blood glucose level of 140 mg/dL still indicates that the client has diabetes and needs to continue managing their condition.
Choice B: Client reports smoking cessation
Smoking cessation is a positive health behavior and can improve overall health, including cardiovascular health, which is often compromised in individuals with diabetes. However, it does not directly indicate the restoration of beta cell function. Beta cell function is specifically related to the pancreas’s ability to produce insulin, and smoking cessation, while beneficial, does not directly impact this.
Choice C: Weight gain of 5 lb
Weight gain can have various implications for a person with type 2 diabetes. While modest weight gain might indicate improved nutritional status or muscle mass, it does not directly indicate the restoration of beta cell function. In fact, weight gain can sometimes worsen insulin resistance, making it harder for beta cells to function effectively.
Correct Answer is C
Explanation
Choice A reason: Synchronized Electrical Cardioversion
Synchronized electrical cardioversion is a procedure that uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle to restore a normal heart rhythm. It is typically used to treat certain types of arrhythmias, such as atrial fibrillation, atrial flutter, and supraventricular tachycardia. However, it is not the primary treatment for heart failure with arrhythmias. This procedure is more suited for acute management of arrhythmias rather than long-term regulation of heart rhythm in heart failure patients.
Choice B reason: Heart Catheterization with Percutaneous Intervention
Heart catheterization with percutaneous intervention, also known as percutaneous coronary intervention (PCI), involves using a catheter to open up blocked coronary arteries. This procedure is primarily used to treat coronary artery disease and improve blood flow to the heart muscle. While it can alleviate symptoms of heart disease and prevent heart attacks, it does not directly address the issue of arrhythmias associated with heart failure. Therefore, it is not the most appropriate choice for regulating heart rhythm in this context.
Choice C reason: Cardiac Resynchronization Therapy (CRT)
Cardiac resynchronization therapy (CRT) is a specialized treatment for heart failure patients who have developed arrhythmias. CRT involves implanting a device called a biventricular pacemaker, which sends electrical signals to both the left and right ventricles to help them contract in a more synchronized manner. This improves the efficiency of the heart’s pumping action and can significantly alleviate symptoms of heart failure, such as shortness of breath and fatigue. CRT is particularly beneficial for patients with moderate to severe heart failure and those whose heart chambers do not beat in unison. This makes CRT the most appropriate choice for regulating heart rhythm in a patient with worsening heart failure and arrhythmias.
Choice D reason: Echocardiogram
An echocardiogram is a diagnostic test that uses ultrasound waves to create images of the heart. It provides detailed information about the heart’s structure and function, including the size and shape of the heart chambers, the movement of the heart walls, and the function of the heart valves. While an echocardiogram is essential for diagnosing and monitoring heart conditions, it is not a treatment procedure. It does not regulate heart rhythm but rather helps in assessing the severity of heart failure and guiding treatment decisions.
