A nurse is reviewing the laboratory results of a client who was hyperventilating during a panic attack.
Which of the following arterial blood gas values should the nurse expect?

pH 7.50 and HCO3 31 mm Hg.

pH 7.30 and HCO3 19 mm Hg.

pH 7.47 and PaCO2 31 mm Hg.

pH 7.32 and PaCO2 50 mm Hg.

Answer and Explanation

The Correct Answer is C

The correct answer is: C.

Choice A reason: A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.

Choice B reason: A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.

Choice C reason: A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.

Choice D reason: A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.

Correct Answer is A

Explanation

Choice A rationale:

"I can plan to eat rice instead of baked potatoes.”. This choice demonstrates an understanding of dietary sources of potassium. Baked potatoes are a good source of potassium, and the client's willingness to substitute rice for baked potatoes indicates that they are aware of alternative potassium-rich foods. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. The client's willingness to make a dietary adjustment is a positive sign.

Choice B rationale:

"Adding pecans will be a change I can readily make.”. While pecans are a good source of potassium, this choice does not directly address the client's ability to substitute a potassium-rich food for one they might need to avoid. It focuses on a new addition to their diet rather than a substitution, making it a less relevant response to the teaching.

Choice C rationale:

"I will eat cantaloupe for my morning snack.”. Cantaloupe is indeed a good source of potassium, but this choice does not indicate an understanding of how to substitute potassium-rich foods in their diet. It only mentions adding cantaloupe as a snack without addressing the potential need for replacing other foods high in potassium. Therefore, it does not fully demonstrate comprehension of the teaching.

Choice D rationale:

"I will miss eating yogurt every day for breakfast.”. This choice expresses a sentiment but does not show an understanding of the teaching regarding dietary sources of potassium. It merely states that the client will miss yogurt without providing any insight into their ability to make appropriate dietary choices to maintain adequate potassium intake.

A. "I will wear stockings with elastic tops.”. B. "I will avoid crossing my legs at the knees.”. C. "I will not go barefoot.”. D. "I will use a thermometer to check the temperature of my bath water.”. .

Correct Answer is A

Explanation

The correct answer is Choice A: "I will wear stockings with elastic tops."

Choice A rationale:

Wearing stockings with elastic tops can constrict blood flow in the legs, which is counterproductive for individuals with peripheral vascular disease. Compression stockings specifically designed for PVD are recommended, but these should be properly fitted and used according to medical advice.

Choice B rationale:

Avoiding crossing the legs at the knees is appropriate for individuals with PVD, as this can impede blood flow and worsen symptoms.

Choice C rationale:

Not going barefoot is important for clients with PVD, as it reduces the risk of injury and infection, which can be more serious due to compromised circulation.

Choice D rationale:

Using a thermometer to check the temperature of bath water is crucial for clients with PVD to avoid burns, since they may have decreased sensation in their extremities.
