A patient's blood gases show a pH of 7.53 and bicarbonate level of 36 mEq/L. The nurse realizes that the patient is demonstrating which acid-base disorder?

Respiratory acidosis.

Metabolic alkalosis.

Respiratory alkalosis.

Metabolic acidosis.

Answer and Explanation

The Correct Answer is B

Metabolic alkalosis.

Choice A rationale:

The given blood gas results show a pH of 7.53, which is alkaline (above the normal range of

7.35 to 7.45), and a high bicarbonate level of 36 mEq/L (normal range is 22 to 26 mEq/L). This combination indicates metabolic alkalosis, a condition where there is an excessive accumulation of bicarbonate in the blood, leading to increased pH.

Choice B rationale:

Metabolic alkalosis is characterized by increased blood bicarbonate levels, which can occur due to conditions like vomiting, diuretic use, or excessive ingestion of bicarbonate-containing substances. It results in symptoms such as muscle twitching, tetany, and respiratory depression.

Choice C rationale:

Respiratory alkalosis is characterized by an elevated blood pH and low carbon dioxide levels (hypocapnia). However, the bicarbonate level is not directly related to respiratory alkalosis, making this choice incorrect based on the given information.

Choice D rationale:

Metabolic acidosis is characterized by a decreased blood pH and low bicarbonate levels. The presented blood gas results show an alkaline pH and high bicarbonate, making this choice incorrect.

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

Explanation

Choice A rationale:

The nurse considered contraction of facial muscles as a finding of hypocalcemia because it is associated with Chvostek's sign, which indicates neuromuscular irritability due to low calcium levels.

Choice B rationale:

Complaints of fingers tingling are indicative of hypocalcemia since tingling sensations (paresthesias) in the extremities can result from decreased calcium levels affecting nerve function.

Choice C rationale:

Carpal spasm with blood pressure measurement is known as Trousseau's sign and is associated with hypocalcemia. When the blood pressure cuff is inflated above systolic pressure, it can cause tetany in the hand if the calcium levels are low.

Choice D rationale:

Asking when foot numbness would go away does not directly relate to hypocalcemia or its symptoms. It is not a finding used to come to the conclusion of hypocalcemia in this scenario.

Choice E rationale:

The heart rate being 88 and regular does not directly indicate hypocalcemia. While hypocalcemia can lead to cardiac arrhythmias, a heart rate of 88 and regular is within the normal range and not a specific finding for hypocalcemia.

A. Hypocalcemia. B. Hypercalcemia. C. Hyperkalemia. D. Hypokalemia.

Correct Answer is C

Explanation

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.
