A nurse is preparing to administer medications to a client who has syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following medications should the nurse question?
Conivaptan hydrochloride 20 mg IV over 30 minutes STAT
Vasopressin 10 mcg PO daily
Sodium chloride tablets 1 g PO three times daily
Tolvaptan 30 mg PO twice daily
The Correct Answer is B
Choice A Reason:
Conivaptan hydrochloride is a vasopressin receptor antagonist used to treat hyponatremia associated with SIADH. It works by blocking the action of ADH, thereby promoting water excretion without losing sodium. This medication is appropriate for managing SIADH.
Choice B Reason:
Vasopressin, also known as antidiuretic hormone (ADH), is not appropriate for a patient with SIADH. SIADH is characterized by excessive release of ADH, leading to water retention and hyponatremia. Administering vasopressin would exacerbate the condition by increasing water retention and further lowering sodium levels.
Choice C Reason:
Sodium chloride tablets are used to manage hyponatremia by increasing sodium levels in the blood. This treatment is appropriate for patients with SIADH to help correct the sodium imbalance caused by excessive ADH.
Choice D Reason:
Tolvaptan is another vasopressin receptor antagonist that is used to treat hyponatremia associated with SIADH. It helps to increase serum sodium levels by promoting water excretion while retaining sodium. This medication is suitable for managing SIADH.

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 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.
