A nurse is reinforcing discharge instructions with the parents of an infant who has been prescribed home oxygen and pulse oximetry monitoring.
Which statement by the parents suggests that further instruction is needed?

Choice A rationale:

Metabolic alkalosis is an acid-base imbalance characterized by excessive loss of acid or excessive gain of bicarbonate produced by an underlying pathologic disorder. It causes metabolic, respiratory, and renal responses, producing characteristic symptoms. One of the manifestations of metabolic alkalosis is cardiovascular abnormalities, such as atrial tachycardia. Therefore, placing the patient on continuous cardiac monitoring is a necessary action to assess the patient’s heart rate and rhythm and detect any abnormalities early.

Choice B rationale:

Insulin is not typically used in the treatment of metabolic alkalosis. Insulin is a hormone that regulates blood sugar levels. It’s not directly related to the body’s acid-base balance. Therefore, obtaining a prescription for insulin for the patient would not be a relevant action in this case.

Choice C rationale:

Administering sodium bicarbonate to a patient with metabolic alkalosis would not be appropriate. Sodium bicarbonate is a base and is often used to treat metabolic acidosis, a condition characterized by an excess of acid in the body. Giving sodium bicarbonate to a patient with metabolic alkalosis, a condition characterized by an excess of base in the body, could potentially worsen the patient’s condition.

Choice D rationale:

Having the patient breathe into a paper bag is a common treatment for respiratory alkalosis, not metabolic alkalosis.

Respiratory alkalosis is caused by hyperventilation, which leads to a decrease in carbon dioxide in the blood. Breathing into a paper bag helps to increase the amount of carbon dioxide the person inhales, helping to restore the acid-base balance. However, metabolic alkalosis is not caused by hyperventilation, so this treatment

Choice A rationale:

Hypertension is not typically a sign of hypokalemia. Hypokalemia, or low potassium levels, can cause symptoms like fatigue, muscle weakness, digestive problems, and frequent urination. Hypertension, or high blood pressure, is not commonly associated with hypokalemia.

Choice B rationale:

Cerebral edema, or swelling in the brain, is not a common symptom of hypokalemia. Hypokalemia is more likely to cause symptoms related to muscle function and digestion, as potassium is an essential mineral that helps regulate muscle contractions, maintain healthy nerve function, and regulate fluid balance.

Choice C rationale:

Muscle weakness is a common symptom of hypokalemia. Potassium helps regulate muscle contractions. When blood potassium levels are low, your muscles produce weaker contractions. This can result in symptoms like muscle weakness and fatigue.

Choice D rationale:

Hyperactive bowel sounds are not typically associated with hypokalemia. Hypokalemia can cause digestive problems, but these are more likely to be issues like constipation rather than increased bowel sounds.
