A patient prescribed spironolactone is demonstrating ECG changes and complaining of muscle weakness. The nurse realizes this patient is exhibiting signs of which electrolyte imbalance?

Hypocalcemia.

Hypercalcemia.

Hyperkalemia.

Hypokalemia.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Hypocalcemia refers to low levels of calcium in the blood, which can present with symptoms like muscle cramps, numbness, and tingling. However, this choice is not relevant to the patient's symptoms in the scenario.

Choice B rationale:

Hypercalcemia is an electrolyte imbalance characterized by high levels of calcium in the blood. It can lead to ECG changes and symptoms like muscle weakness, confusion, and constipation. However, this is not the correct answer in the given scenario.

Choice C rationale:

The patient's symptoms of ECG changes and muscle weakness are consistent with hyperkalemia. Spironolactone is a potassium-sparing diuretic, and its use can lead to increased potassium levels in the blood (hyperkalemia), which can affect the heart's electrical activity and cause muscle weakness.

Choice D rationale:

Hypokalemia is a condition where there is a low level of potassium in the blood. It can lead to muscle weakness, ECG changes, and other symptoms, but it is not the correct answer in this specific situation involving spironolactone use.

Correct Answer is C

Explanation

PacO2 50 mm Hg. Choice A rationale:

Potassium levels are not directly related to respiratory acidosis. Potassium levels may be affected in certain conditions, but they are not specific indicators of respiratory acidosis.

Choice B rationale:

HCO3- (bicarbonate) levels may be elevated in metabolic alkalosis, not respiratory acidosis. In respiratory acidosis, the primary abnormality is an increased PacO2, not HCO3-.

Choice C rationale:

The partial pressure of carbon dioxide (PacO2) is a key parameter in diagnosing respiratory acidosis. In this case, a PacO2 of 50 mm Hg suggests hypoventilation and an excess of carbon dioxide in the blood, contributing to acidosis.

Choice D rationale:

The pH level given (pH 7.45) is within the normal range, which contradicts the diagnosis of respiratory acidosis. In respiratory acidosis, the pH would be expected to be below the normal range of 7.35-7.45 due to increased carbon dioxide levels.

A. Administering a potassium-sparing diuretic. B. Administering sodium polystyrene sulfonate. C. Initiating an IV potassium infusion. D. Encouraging the client to eat bananas.

Correct Answer is B

Explanation

The correct answer is choice B) Administering sodium polystyrene sulfonate.

Choice A rationale:

Administering a potassium-sparing diuretic is not appropriate for a client with hyperkalemia (high potassium levels). Potassium-sparing diuretics would further increase potassium levels, worsening the condition.

Choice B rationale:

Sodium polystyrene sulfonate is used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestines, which helps to lower serum potassium levels by excreting it through the stool.

Choice C rationale:

Initiating an IV potassium infusion would be contraindicated in this situation as it would increase the already elevated potassium levels, potentially leading to dangerous cardiac complications.

Choice D rationale:

Encouraging the client to eat bananas is not advisable because bananas are high in potassium, which would exacerbate hyperkalemia.
