A nurse is reviewing a client's CBC findings and discovers that the client's platelet count is 9,000/mm3. The nurse should monitor the client for which of the following conditions?

Spontaneous bleeding

Infection

Oliguria

Hyperactive deep tendon reflexes

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

A. Metformin is an oral antidiabetic medication commonly used to manage type 2 diabetes mellitus. It can cause a rare but serious side effect called lactic acidosis, especially in situations where there is impaired kidney function or when the drug interacts with contrast dye used in procedures like cardiac catheterization.
B. Carvedilol is a beta-blocker used to manage hypertension and heart failure. It does not have a significant interaction with contrast dye that would increase the risk of AKI.
C. Atorvastatin is a statin medication used to lower cholesterol levels. It does not interact with contrast dye in a way that increases the risk of AKI.
D. Nitroglycerin is a vasodilator used to relieve angina symptoms. It does not interact with contrast dye in a way that increases the risk of AKI.

A. Metolazone B. Furosemide C. Hydrochlorothiazide D. Spironolactone

Correct Answer is D

Explanation

A. Metolazone is a thiazide-like diuretic that works primarily in the distal convoluted tubule of the nephron. It can lead to hyponatremia due to its mechanism of increasing sodium and water excretion. However, it is not typically associated with hyperkalemia.
B. Furosemide is a loop diuretic that acts on the ascending loop of Henle. It primarily causes loss of sodium, potassium, and chloride ions. While it can lead to hypokalemia (low potassium levels) due to increased potassium excretion, it does not typically cause hyperkalemia or hyponatremia.
C. Hydrochlorothiazide is a thiazide diuretic that acts on the distal convoluted tubule. It can cause hyponatremia due to increased sodium and water excretion. It may also lead to hypokalemia but is not typically associated with hyperkalemia.
D. Spironolactone is a potassium-sparing diuretic that works by antagonizing aldosterone receptors in the distal nephron, leading to retention of potassium and excretion of sodium. It can cause hyperkalemia due to its potassium-sparing effects. Additionally, it may also lead to hyponatremia, although less commonly than thiazide diuretics.
