A nurse is caring for a client who has diabetic ketoacidosis (DK

Metabolic alkalosis

Metabolic acidosis

Respiratory alkalosis

Respiratory acidosis

Answer and Explanation

The Correct Answer is B

Choice A reason: Metabolic alkalosis is a condition characterized by an elevated pH in body tissues, typically due to an excess of bicarbonate or a loss of hydrogen ions. This condition is not associated with Kussmaul breathing. Kussmaul breathing is a deep and labored breathing pattern often seen in patients with metabolic acidosis, not alkalosis. In metabolic alkalosis, the body does not need to expel excess acid through rapid breathing, so Kussmaul respirations are not observed.

Choice B reason: Metabolic acidosis is a condition where there is an excess of acid in the body due to the accumulation of acid or the loss of bicarbonate. This condition is commonly seen in diabetic ketoacidosis (DKA), where the body produces high levels of ketones, leading to acidosis. Kussmaul breathing is a compensatory mechanism in metabolic acidosis, where the body attempts to reduce the acid level by expelling carbon dioxide through rapid, deep breaths. This type of breathing helps to lower the blood’s acidity by reducing the concentration of carbon dioxide, which is an acid.

Choice C reason: Respiratory alkalosis is a condition where there is a decrease in carbon dioxide levels in the blood due to excessive breathing or hyperventilation. This condition leads to an increase in blood pH, making it more alkaline. Kussmaul breathing is not associated with respiratory alkalosis because it is a response to metabolic acidosis, not a condition where the body is already expelling too much carbon dioxide.

Choice D reason: Respiratory acidosis is a condition where there is an excess of carbon dioxide in the blood due to inadequate respiration. This leads to a decrease in blood pH, making it more acidic. While respiratory acidosis involves an acidic environment, Kussmaul breathing is specifically a response to metabolic acidosis, not respiratory acidosis. In respiratory acidosis, the body would not use Kussmaul respirations as a compensatory mechanism.

Correct Answer is B

Explanation

Choice A Reason:

Conivaptan hydrochloride is a vasopressin receptor antagonist used to treat hyponatremia in patients with SIADH. It works by blocking the action of vasopressin, thereby promoting water excretion without significant loss of sodium. This helps to correct the water imbalance caused by SIADH. Conivaptan is typically administered intravenously and is effective in increasing serum sodium levels.

Choice B Reason:

Vasopressin, also known as antidiuretic hormone (ADH), is contraindicated in patients with SIADH because it exacerbates the condition. SIADH is characterized by excessive release of ADH, leading to water retention and hyponatremia. Administering vasopressin would further increase water reabsorption in the kidneys, worsening the hyponatremia.

Choice C Reason:

Sodium chloride tablets are used to manage hyponatremia in SIADH by increasing sodium intake. This helps to counteract the dilutional hyponatremia caused by excessive water retention. Sodium chloride tablets are often prescribed alongside fluid restriction to help raise serum sodium levels.

Choice D Reason:

Tolvaptan is another vasopressin receptor antagonist used to treat hyponatremia in SIADH. It works similarly to conivaptan by blocking the action of vasopressin, promoting water excretion, and increasing serum sodium levels. Tolvaptan is typically administered orally and is effective in managing SIADH.

A. Serum phosphate levels B. Serum calcium levels C. Serum sodium levels D. Blood urea nitrogen (BUN)

Correct Answer is C

Explanation

Choice A reason:

Serum phosphate levels are not the primary concern in the management of diabetes insipidus (DI). While phosphate levels are important for overall health, they do not directly relate to the condition or its treatment with desmopressin. DI primarily affects water balance and sodium levels in the body.

Choice B reason:

Serum calcium levels, although important, are not the most critical lab value to monitor in a client with DI receiving desmopressin. Calcium levels are crucial for bone health and various metabolic functions, but they do not directly reflect the effectiveness or complications of desmopressin therapy.

Choice C reason:

Serum sodium levels are the most important lab value to monitor in a client with DI receiving desmopressin. DI causes an imbalance in water regulation, leading to excessive urination and potential dehydration. Desmopressin helps to reduce urine output and maintain water balance, but it can also lead to water retention and hyponatremia (low sodium levels). Monitoring serum sodium is crucial to prevent complications such as seizures, confusion, and other neurological symptoms associated with hyponatremia.

Choice D reason:

Blood urea nitrogen (BUN) levels are useful in assessing kidney function and hydration status, but they are not the primary concern in the management of DI with desmopressin. While BUN levels can provide valuable information about renal function, they do not directly indicate the effectiveness or potential complications of desmopressin therapy.
