A nurse is reviewing the laboratory values of a patient receiving total parenteral nutrition (TPN). The glucose is 72 mg/dL, chloride is 100 mEq/L, sodium is 138 mEq/L, and potassium is 3.0 mEq/L. What action should the nurse plan to take?
Administer glucagon IM.
Discontinue the TPN infusion.
Request a potassium replacement.
Check the patient for a positive Chvostek’s sign.
The Correct Answer is C
The correct answer is Choice C.
Step 1 is to interpret the laboratory values. The glucose level is within the normal range (7099 mg/dL). The chloride level is within the normal range (97-107 mEq/L). The sodium level is within the normal range (135-145 mEq/L). However, the potassium level is low (normal range is 3.5-5.0 mEq/L)89101112.
Step 2 is to plan the action based on the interpretation. Given the low potassium level, the nurse should plan to request a potassium replacement

Correct Answer is B
Explanation
Choice A rationale
Respiratory alkalosis is typically associated with hyperventilation, which can occur in conditions such as anxiety, fever, or certain lung diseases. However, it is less likely in a patient who is nauseous and vomiting.
Choice B rationale
Metabolic alkalosis is a condition that can occur due to the loss of acid from the body, which can happen when a patient is vomiting. When a person vomits, they lose stomach acid (hydrochloric acid), and this can disrupt the acid-base balance in the body, leading to metabolic alkalosis.
Choice C rationale
Metabolic acidosis is typically associated with conditions that cause the accumulation of acid in the body or the loss of bicarbonate, such as kidney disease, lactic acidosis, or certain poisonings. It is less likely in a patient who is nauseous and vomiting.
Choice D rationale
Respiratory acidosis is typically associated with conditions that cause an inability to remove enough carbon dioxide from the body, such as chronic obstructive pulmonary disease (COPD) or airway obstruction. It is less likely in a patient who is nauseous and vomiting.
Correct Answer is ["A","D","E"]
Explanation
A. Hypotension: Frequent vomiting and diarrhea can cause dehydration, which can lead to hypotension.
B. Bradycardia: Bradycardia is not typically a symptom of dehydration caused by vomiting and diarrhea.
C. Pale yellow urine: Dehydration can cause urine to become concentrated, resulting in a darker color, not pale yellow.
D. Poor skin turgor: Dehydration can cause poor skin turgor, which is skin that lacks elasticity.
E. Flat neck veins: Dehydration can cause flat neck veins when the patient is lying supine.
