A nurse is gathering data on a patient who has diarrhea.
Which of the following findings is a sign of hypokalemia?

The correct answer is: B. Decreased deep tendon reflexes.

Choice A rationale: Wheezing is not typically associated with hyperkalemia. It is more commonly related to respiratory conditions.

Choice B rationale: Hyperkalemia can cause decreased deep tendon reflexes due to the effect of high potassium levels on nerve conduction and muscle function.

Choice C rationale: Hypoactive bowel sounds are not a common sign of hyperkalemia. They are more often associated with gastrointestinal issues.

Choice D rationale: Cerebral edema is not related to hyperkalemia. It is usually associated with conditions affecting the brain, such as trauma or infections.

Choice A rationale:

Metabolic alkalosis can occur in clients who have excessive vomiting because of the loss of hydrochloric acid. When a person vomits, they lose hydrochloric acid, and the loss of this acid can cause the blood to become more basic. This shift in pH can lead to metabolic alkalosis, a condition characterized by high levels of bicarbonate in the blood, which makes it more alkaline (or less acidic). Symptoms of metabolic alkalosis can include muscle twitching, hand tremor, nausea or vomiting, and tingling in the face, hands or feet. In severe cases, it can cause prolonged muscle contractions or seizures.

Choice B rationale:

Respiratory acidosis is a condition that occurs when the lungs can’t remove enough carbon dioxide (CO2) from the body, which causes the body’s fluids, especially the blood, to become too acidic. This can occur due to conditions that affect the lungs such as chronic obstructive pulmonary disease (COPD), asthma, or sleep apnea. However, in the case of a patient experiencing nausea and vomiting, respiratory acidosis is less likely to be the primary concern.

Choice C rationale:

Metabolic acidosis occurs when the body produces too much acid, or when the kidneys aren’t removing enough acid from the body. This can be caused by conditions such as kidney disease, lactic acidosis, or ketoacidosis. In the case of a patient experiencing nausea and vomiting, the primary concern would not typically be metabolic acidosis, as vomiting leads to a loss of stomach acid, which would more likely result in a state of alkalosis, not acidosis.

Choice D rationale:

Respiratory alkalosis is a condition that occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the blood is too alkaline, it means that it is not carrying enough carbon dioxide. This condition can be caused by fever, hyperventilation, or lack of oxygen. In the case of a patient experiencing nausea and vomiting, respiratory alkalosis is not typically the primary concern.
