A client with diabetic ketoacidosis (DKA) is receiving an IV infusion of 0.9% sodium chloride and insulin.
Two hours later, the client’s serum laboratory results show a decrease in the serum blood glucose from 580 to 430 mg/dL (32.2 to 23.86 mmol/L). What additional laboratory result is most important for the nurse to monitor?
Serum sodium.
Serum potassium.
Blood urea nitrogen (BUN).
Urine ketones.
The Correct Answer is B
Choice A rationale
While monitoring serum sodium levels is important in a client with DKA, it is not the most critical. Hyperglycemia can lead to a state of effective osmotic diuresis, which can cause sodium depletion.
Choice B rationale
Serum potassium levels are crucial to monitor in a client with DKA3. Despite total body potassium depletion, serum potassium levels may be high or normal upon presentation due to acidosis and insulin deficiency. However, with insulin treatment, potassium will shift back into the cells, potentially leading to life-threatening hypokalemia.
Choice C rationale
Blood urea nitrogen (BUN) might be elevated due to dehydration, but it is not the most critical lab value to monitor in the management of DKA3.
Choice D rationale
Urine ketones are not as important to monitor as serum potassium in DKA. The presence of ketones in urine only confirms that the body is breaking down fat, not the severity of DKA3.

Correct Answer is B
Explanation
Choice A rationale
Addiction refers to a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. The intricate handwashing ritual that lasts two hours or more described by the client does not indicate substance use or dependency, which are common characteristics of addiction.
Choice B rationale
Compulsion refers to repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rules that must be applied rigidly. The client’s intricate handwashing ritual that lasts two hours or more and their concern about maintaining cleanliness align with the definition of a compulsion.
Choice C rationale
Obsession refers to recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and unwanted. While the client’s concern about maintaining cleanliness could potentially be seen as an obsession, the act of handwashing is a behavior, which aligns more with the definition of a compulsion.
Choice D rationale
Phobia refers to an extreme or irrational fear of or aversion to something. The client’s behavior does not indicate an extreme or irrational fear but rather a compulsion to maintain cleanliness through an intricate handwashing ritual.
Correct Answer is A
Explanation
Choice A rationale
Nadolol is a beta-blocker that can decrease heart rate and contractility, which can potentially exacerbate heart failure and lead to cardiogenic shock.
Choice B rationale
Captopril is an angiotensin-converting enzyme (ACE) inhibitor that is often used in the treatment of heart failure. It works by relaxing blood vessels and reducing the workload of the heart.
Choice C rationale
Digoxin is a cardiac glycoside that is used to treat heart failure and certain heart arrhythmias. It works by increasing the force of the heart’s contractions, which can improve heart function.
Choice D rationale
Hydrochlorothiazide is a diuretic that is often used in the treatment of heart failure. It works by helping the body get rid of excess fluid, which can reduce the workload of the heart.
