A nurse in a clinic is caring for a client who has a prescription for digoxin. Which of the following statements indicates the client is experiencing digoxin toxicity?
"My tongue is red and beefy."
"My vision seems blurry."
"I am gaining weight."
"I am constipated."
The Correct Answer is B
A. This statement suggests symptoms of vitamin B12 deficiency or glossitis, which are not typical signs of digoxin toxicity. Therefore, it is unlikely to indicate digoxin toxicity.
B. Blurred vision is a common neurological symptom of digoxin toxicity. It occurs due to disturbances in visual acuity and color vision, which can manifest as seeing halos around lights or difficulty focusing. Therefore, this statement is indicative of potential digoxin toxicity.
C. Weight gain can occur due to fluid retention, which is a symptom of heart failure rather than digoxin toxicity. Digoxin toxicity typically presents with neurological and gastrointestinal symptoms rather than weight gain.
D. Constipation is not typically associated with digoxin toxicity. Gastrointestinal symptoms such as nausea, vomiting, and anorexia are more common with digoxin toxicity, but constipation is not a specific indicator.

Correct Answer is D
Explanation
A. Metabolic alkalosis is characterized by an increase in bicarbonate (HCO3-) levels in the blood, resulting in an elevated pH (>7.45). Shallow respirations are less likely to cause metabolic alkalosis directly.
B. This is not likely the initial risk. Respiratory alkalosis occurs due to hyperventilation, leading to excessive elimination of CO2 (carbon dioxide), which raises the blood pH (>7.45). Shallow respirations typically result in retention of CO2, leading to respiratory acidosis rather than alkalosis.
C. Metabolic acidosis occurs when there is an increase in acid (decreased pH <7.35) or a decrease in bicarbonate levels in the blood. Shallow respirations can lead to hypoventilation and retention of CO2, resulting in respiratory acidosis initially.
D. Shallow respirations at a rate of 9 breaths per minute reduce the elimination of CO2, leading to its accumulation in the blood. This accumulation lowers the blood pH (<7.35), causing respiratory acidosis. Therefore, the client is initially at risk for developing respiratory acidosis due to ineffective ventilation.
Correct Answer is A
Explanation
A. This condition occurs because the suctioning can lead to a significant loss of hydrochloric acid from the stomach. Since hydrochloric acid is one of the components that maintain the acid-base balance in the body, its loss can lead to an increase in blood pH, causing alkalosis
B. Respiratory acidosis occurs due to retention of carbon dioxide (CO2), leading to an increase in PaCO2 and a decrease in pH. In the context of a small bowel obstruction with nasogastric tube suctioning, this is less likely unless there are concurrent respiratory issues.
C. This condition occurs because the suctioning can lead to a significant loss of hydrochloric acid from the stomach. Since hydrochloric acid is one of the components that maintain the acid-base balance in the body, its loss can lead to an increase in blood pH, causing alkalosis. Acidosis is, therefore, unlikely.
D. Respiratory alkalosis occurs due to hyperventilation, leading to a decrease in PaCO2 and an increase in pH. This is less likely in the context of nasogastric tube suctioning unless there are other contributing factors.
