A nurse is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the nurse expect?

Potassium 3.3 mEq/L.

HCO3- 30 mEq/L.

PacO2 50 mm Hg.

pH 7.45.

Answer and Explanation

The Correct Answer is C

PacO2 50 mm Hg. Choice A rationale:

Potassium levels are not directly related to respiratory acidosis. Potassium levels may be affected in certain conditions, but they are not specific indicators of respiratory acidosis.

Choice B rationale:

HCO3- (bicarbonate) levels may be elevated in metabolic alkalosis, not respiratory acidosis. In respiratory acidosis, the primary abnormality is an increased PacO2, not HCO3-.

Choice C rationale:

The partial pressure of carbon dioxide (PacO2) is a key parameter in diagnosing respiratory acidosis. In this case, a PacO2 of 50 mm Hg suggests hypoventilation and an excess of carbon dioxide in the blood, contributing to acidosis.

Choice D rationale:

The pH level given (pH 7.45) is within the normal range, which contradicts the diagnosis of respiratory acidosis. In respiratory acidosis, the pH would be expected to be below the normal range of 7.35-7.45 due to increased carbon dioxide levels.

Correct Answer is ["A","D"]

Explanation

The correct answer is A. Limit intake of canned soups and D. Read labels on foods before eating.

Choice A rationale:

Canned soups often contain high levels of sodium, which can contribute to exceeding the recommended daily sodium intake. Limiting these can help manage sodium levels effectively.

Choice B rationale:

Choosing diet sodas over bottled water is not advisable. Diet sodas can still contain sodium and other additives that are not beneficial for a low-sodium diet. Bottled water is a better choice as it typically contains no sodium.

Choice C rationale:

Bottled salad dressings often contain high amounts of sodium. Opting for homemade or low-sodium versions is a better strategy for maintaining a low-sodium diet.

Choice D rationale:

Reading labels on foods before eating is crucial for identifying hidden sources of sodium and making informed dietary choices. This practice helps in adhering to a low-sodium diet by avoiding foods with high sodium content.

A. Urine specific gravity 1.035. B. BUN 19 mg/dL. C. Hematocrit 44.9%. D. Sodium 155 mEq/L.

Correct Answer is A

Explanation

Sodium 155 mEq/L. Choice A rationale:

A urine specific gravity of 1.035 indicates concentrated urine and is consistent with fluid volume deficit. However, it is not the most specific finding for this condition.

Choice B rationale:

A BUN (blood urea nitrogen) level of 19 mg/dL can be a normal value. It is within the reference range (usually around 7-20 mg/dL) and does not provide specific information about fluid volume deficit.

Choice C rationale:

A hematocrit of 44.9% can also be within the normal range for some individuals, and while it can be elevated in cases of fluid volume deficit, it is not as sensitive as other parameters for detecting this condition.

Choice D rationale:
This is the correct answer because a sodium level of 155 mEq/L is elevated and indicates hypernatremia, which is associated with fluid volume deficit. Hypernatremia occurs when there is a relative lack of water in relation to the sodium concentration in the blood, and it can lead to dehydration
