The nurse receives a health care provider's prescription to change a patient's IV from D5. half-normal saline with 40 mEq KCl/L to DSNS with 20 mEq KCl/L. Which set of serum laboratory values supports the rationale for this IV prescription change?

Sodium level of 136 mEq/L, potassium level of 4.5 mEq/L.

Sodium level of 145 mEq/L, potassium level of 4.8 mEq/L.

Sodium level of 135 mEq/L, potassium level of 3.6 mEq/L.

Sodium level of 144 mEq/L, potassium level of 3.7 mEq/L.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

The sodium level is within the normal range, but the potassium level is slightly elevated. This does not support the rationale for changing the IV prescription to a lower potassium concentration.

Choice B rationale:

The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.

Choice C rationale:

Sodium level of 135 mEq/L, potassium level of 3.6 mEq/L is the correct answer. In this option, both sodium and potassium levels are within normal ranges. Changing the IV prescription to DSNS with 20 mEq KCl/L ensures that the patient receives adequate hydration (from the dextrose and normal saline) without causing hyperkalemia.

Choice D rationale:

The sodium level is slightly elevated, and the potassium level is within the normal range. This does not support the rationale for changing the IV prescription to a lower potassium concentration.

Correct Answer is C

Explanation

The correct answer is c. Respiratory acidosis.

Choice A reason: Metabolic acidosis is incorrect because the HCO3 level is normal. In metabolic acidosis, we would expect to see a decreased HCO3.

Choice B reason: Metabolic alkalosis is incorrect because the HCO3 level is normal. In metabolic alkalosis, we would expect to see an increased HCO3.

Choice C reason: The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component). The low pH and increased PaCO2 suggest respiratory acidosis.

Choice D reason: Respiratory alkalosis is incorrect because the PaCO2 level is elevated, not decreased. In respiratory alkalosis, we would expect to see a decreased PaCO2.

A. Skeletal pain. B. Enlarged lymph nodes. C. T-cell blasts in the lymph node. D. Lymphoblasts in the cerebrospinal fluid.

Correct Answer is B

Explanation

Choice A rationale:
Skeletal pain is not a typical finding in stage I Hodgkin lymphoma. Hodgkin lymphoma typically presents with painless enlarged lymph nodes, which is a hallmark symptom of the disease.
Choice B rationale:
Enlarged lymph nodes are a characteristic feature of Hodgkin lymphoma. In stage I, the disease is localized to one group of lymph nodes.
Choice C rationale:
T-cell blasts in the lymph node are not specific to Hodgkin lymphoma. Hodgkin lymphoma is characterized by the presence of Reed-Sternberg cells, which are large abnormal B cells, not T-cell blasts.
Choice D rationale:
Lymphoblasts in the cerebrospinal fluid are not associated with Hodgkin lymphoma. Involvement of the central nervous system is rare in Hodgkin lymphoma and typically does not lead to the presence of lymphoblasts in the cerebrospinal fluid.
