A client with diabetes insipidus (DI) has an average urinary output of 500 ml. of dilute urine every hour for the last 4 hours. Which laboratory test is most important for the nurse to monitor?

A) Incorrect- Furosemide is a loop diuretic used to treat conditions such as edema and hypertension. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
B) Incorrect- Low-dose aspirin is often used for its antiplatelet effects to prevent cardiovascular events. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.
C) Correct- Allopurinol is a medication used to treat gout by reducing the production of uric acid in the body. However, allopurinol can also increase the risk of forming calcium oxalate kidney stones, which is the type of kidney stone mentioned in the client's history. Calcium oxalate stones are the most common type of kidney stone, and they are composed primarily of calcium and oxalate. In this case, the client has a history of gout and is prescribed allopurinol. The nurse should bring the client's prescription for allopurinol to the healthcare provider's attention because

it has the potential to contribute to the formation of kidney stones, which could exacerbate the client's existing condition.
D) Incorrect- Enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension and heart failure. It does not directly relate to the client's history of gout or the risk of calcium kidney stones.

The correct answer/s is Choice/s A, C, and E.

Choice A rationale: Obtaining the client’s tympanic temperature measurement is a crucial step. The client’s confusion and disorientation could be symptoms of an infection, such as a urinary tract infection or pneumonia. Infections in older adults can often present with atypical symptoms, including changes in mental status. Therefore, checking the client’s temperature can help identify if the client has a fever, which is a common sign of an infection.

Choice B rationale: While it’s always important to be aware of a client’s allergies, especially when administering medications, it doesn’t directly address the immediate concern of the client’s altered mental status. Therefore, it’s not the most appropriate action to take in response to the situation described.

Choice C rationale: Asking if the client is experiencing any pain with urination is relevant because urinary tract infections (UTIs) are common in older adults and can cause confusion and other changes in mental status. Pain during urination is a common symptom of a UTI.

Choice D rationale: Encouraging the intake of high protein foods is generally a good recommendation for older adults to maintain their strength and energy levels. However, it’s not directly related to the client’s current symptoms of confusion and disorientation.

Choice E rationale: Determining if the client has recently experienced a fall is important. Falls in older adults can lead to injuries, such as a head injury, which can cause confusion and other changes in mental status. Additionally, some medications used to treat pain after a fall can also contribute to confusion.
