A nurse assesses a diabetic client who is admitted with an acid-base imbalance. The client's arterial blood gas values are pH 7.39, PaCO2 27 mm Hg, and HCO3 19 mEq/L. Which sign or symptom does the nurse identify as an example of the client's compensatory mechanisms?

Increased release of acids from the kidneys.

Increased urinary output.

Increased thirst and hunger.

Increased rate and depth of respirations.

Answer and Explanation

The Correct Answer is D

A.   This is not a compensatory mechanism for metabolic acidosis. In fact, during metabolic acidosis, the kidneys excrete hydrogen ions (acid) and reabsorb bicarbonate (base) to help normalize the pH of the blood.
B.   Increased urinary output (polyuria) is not typically a direct compensatory response to metabolic acidosis. However, metabolic acidosis can lead to osmotic diuresis in certain conditions, which may increase urinary output as the body tries to excrete excess acids and maintain electrolyte balance.
C.   Increased thirst (polydipsia) and hunger (polyphagia) are not typical compensatory responses to metabolic acidosis. These symptoms are more associated with hyperglycemia in diabetes rather than acid-base disturbances.
D.   During metabolic acidosis, the respiratory system compensates by increasing the rate and depth of respirations (hyperventilation). By blowing off more CO2 (carbon dioxide), the body tries to decrease the

amount of carbonic acid in the blood, thereby increasing the pH towards normal. This compensatory mechanism helps to raise the pH back towards the normal range (7.35-7.45).

Correct Answer is ["B","C","D"]

No explanation

A. Spontaneous bleeding B. Infection C. Oliguria D. Hyperactive deep tendon reflexes

Correct Answer is A

Explanation

A. Thrombocytopenia (low platelet count) predisposes the client to spontaneous bleeding. This can manifest as petechiae (small red or purple spots on the skin), purpura (larger areas of purple discoloration), mucosal bleeding (such as nosebleeds or bleeding gums), or internal bleeding (such as gastrointestinal or intracranial bleeding). Monitoring for signs of bleeding is essential to promptly intervene and prevent complications.
B. While infections can occur in any client, a low platelet count does not directly predispose the client to infection. Thrombocytopenia primarily affects hemostasis rather than immune function.
C. Oliguria refers to decreased urine output, typically less than 400 mL/day in adults. It is not directly related to thrombocytopenia but may occur in conditions affecting kidney function or fluid balance.
D. Hyperactive deep tendon reflexes can indicate neurological conditions or electrolyte imbalances but are not associated with thrombocytopenia.
