A nurse is reviewing the laboratory data of a client prior to administering IV tobramycin.
Which of the following laboratory values should the report to the provider?
Sodium 137 mEq
Hgb 15 g/
Hct 439
Creatinine 2.5 mg/dl
The Correct Answer is D
Choice A rationale:
A sodium level of 137 mEq is within a normal range.
Choice B rationale:
A hemoglobin level of 15 g/dL is within a normal range.
Choice C rationale:
A hematocrit level of 43% is within a normal range.
Choice D rationale:
Creatinine 2.5 mg/dL is elevated, indicating possible kidney impairment. Tobramycin is known to be nephrotoxic, and administering it to a patient with impaired kidney function could exacerbate the condition. Therefore, this value should be reported to the provider before administering the medication.

Correct Answer is D
Explanation
A. Taking ferrous gluconate with 8 ounces of milk is incorrect. Calcium in milk can interfere with the absorption of iron, reducing its effectiveness. The client should be instructed to avoid taking iron supplements with dairy products.
B. It is not necessary to notify the provider if stools turn black. Black stools are a common and harmless side effect of iron supplementation due to the unabsorbed iron in the gastrointestinal tract. The client should be informed of this expected side effect.
C. Taking an antacid with ferrous gluconate is incorrect. Antacids can reduce the absorption of iron by altering the stomach's pH. If the client experiences stomach upset, the medication can be taken with food, although this may slightly reduce absorption.
D. Staying upright for at least 15 minutes after taking ferrous gluconate is correct. This practice helps prevent esophageal irritation, which can occur if the medication remains in contact with the esophageal lining. This statement indicates an understanding of the teaching.
Correct Answer is A
Explanation
Choice A rationale:
Calcium gluconate is used to treat hypermagnesemia by antagonizing the effects of excess magnesium and reducing its impact on cardiac function.
Choice B rationale:
Flumazenil is used to reverse the effects of benzodiazepine overdose, not to treat hypermagnesemia.
Choice C rationale:
Protamine sulfate is used to reverse the effects of heparin, not to treat hypermagnesemia.
Choice D rationale:
Acetylcysteine is used to treat acetaminophen overdose, not to treat hypermagnesemia.
