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."

Answer and Explanation

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. A pH of 7.45 indicates alkalosis, not acidosis. In respiratory acidosis, the pH would be lower than normal (below 7.35) due to the accumulation of carbon dioxide.
B. A bicarbonate (HCO3-) level of 30 mEq/L is within the normal range (typically 22-26 mEq/L). Bicarbonate levels may be normal or slightly elevated in respiratory acidosis as a compensatory mechanism to buffer the excess acid.
C. Potassium levels can vary in respiratory acidosis but are not typically specified by a specific value. The level of potassium is more directly related to metabolic acid-base disturbances rather than respiratory acidosis.
D. An elevated PaCO2 level above 45 mm Hg indicates respiratory acidosis. In this scenario, a PaCO2 of 50 mm Hg suggests that the client is retaining carbon dioxide, leading to an acidotic state (lower pH).

A. Apply a warm compress to the IV site. B. Apply firm pressure to the plunger of the syringe during the IV flush to improve patency. C. Remove the IV saline lock. D. Inject the solution more slowly while flushing the IV saline lock

Correct Answer is D

Explanation

A. Applying a warm compress can help dilate the blood vessels, potentially improving circulation around the IV site. This can sometimes alleviate discomfort caused by irritation or infiltration. However, if there is significant pain or swelling, warm compresses may not be sufficient.
B. Applying firm pressure on the syringe plunger during the flush is not recommended. Excessive force could potentially cause damage to the vein or exacerbate pain and discomfort. It's important to flush gently to maintain patency and avoid causing further irritation or complications.
C. If the client reports pain above the IV saline lock and there are signs of infiltration (such as swelling, coolness, or blanching of the skin around the site), removing the IV saline lock may be necessary. Infiltration occurs when IV fluid leaks into the surrounding tissue instead of flowing into the vein, which can lead to discomfort and complications.
D. Injecting the solution more slowly during the flush can help minimize discomfort and reduce the risk of causing further damage. Slower infusion allows for better tolerance by the vein and surrounding tissues, decreasing the likelihood of pain or infiltration.
