A client arrives at the emergency department with chest pain after taking sildenafil.
Based on the client's history, which medication should the nurse withhold?

Choice A rationale:

A pH level of 7.35 to 7.45 and HCO3- level of 22 to 26 mEq/L indicate a resolution of ketoacidosis. The normal pH range for the body is 7.35 to 7.45, and a return to this range indicates that the body’s acid-base balance has been restored. The bicarbonate (HCO3-) level is a measure of the metabolic component of the body’s acid-base balance, and the normal range is 22 to 26 mEq/L. A return to this range indicates that the metabolic acidosis caused by the ketoacidosis has been resolved.

Choice B rationale:

A pH level of 7.25 to 7.35 and HCO3- level of 18 to 22 mEq/L would indicate that the client is still in a state of mild acidosis, as the pH is below the normal range and the bicarbonate level is also slightly low, indicating a metabolic acidosis.

Choice C rationale:

A pH level of 7.15 to 7.25 and HCO3- level of 14 to 18 mEq/L would indicate a moderate acidosis. Both the pH and bicarbonate levels are significantly below their normal ranges, indicating a significant disruption in the body’s acid-base balance.

Choice D rationale:

A pH level of 7.05 to 7.15 and HCO3- level of 10 to 14 mEq/L would indicate severe acidosis, which would be life-threatening if not corrected. Both the pH and bicarbonate levels are far below their normal ranges, indicating a severe disruption in the body’s acid-base balance. In conclusion, choice A is correct because it represents values within the normal ranges for both pH and bicarbonate, indicating a resolution of ketoacidosis.

Choice A rationale:

A bottle is generally much better than using a pacifier. This statement is not accurate. Prolonged bottle use, especially with sugary liquids like milk, can have adverse effects on a child's dental health. It can lead to an increased risk of cavities, similar to prolonged pacifier use.

Choice B rationale:

The bottle will assist in preventing thumb sucking. This statement is incorrect. While a bottle may provide comfort to a child, it does not prevent thumb sucking. Thumb sucking is a separate behavior that may also have dental implications if it persists beyond a certain age.

Choice C rationale:

Prolonged bottle use can increase the risk for cavities. This response is correct. Prolonged bottle use, especially with milk or sugary beverages, can expose the child's teeth to prolonged contact with sugars, increasing the risk of cavities. It's important for the nurse to educate the mother about the potential dental risks associated with extended bottle use.

Choice D rationale:

Using milk rather than juice helps to avoid tooth decay. While milk is generally considered a healthier choice than juice, the key issue in this scenario is the prolonged use of the bottle, regardless of its content. Prolonged bottle use with any liquid, including milk, can still increase the risk of cavities.
