A nurse is caring for a client who has a magnesium level of 2.7 mEq/L. Which of the following interventions should the nurse plan to take?
Initiate continuous cardiac monitoring.
Administer 40 mEq/L potassium chloride PO with orange juice.
Provide a diet rich in legumes, nuts, and green vegetables.
Monitor the client for tetany.
The Correct Answer is A
- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.
- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.
- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.
- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs

Correct Answer is C
Explanation
Choice A rationale:
A random plasma glucose level of 176 mg/dL indicates high blood sugar at the time of the test. Random glucose levels are not ideal for assessing glycemic control as they can vary based on recent food intake and stressors.
Choice B rationale:
Triglyceride levels are not used to assess glycemic control. They measure the amount of triglycerides in the bloodstream and are related to lipid metabolism, not glucose control.
Choice C rationale:
HbA1c (glycated hemoglobin) is a long-term measure of blood glucose control. An HbA1c level of 6.8% indicates acceptable glycemic control in a person with diabetes. The normal range for HbA1c is typically less than 6.5%. This test reflects the average blood sugar level over the past 2-3 months, giving a better understanding of overall glucose control.
Choice D rationale:
Fasting blood glucose of 120 mg/dL is slightly elevated. While fasting blood glucose levels below 100 mg/dL are generally considered normal, levels between 100-125 mg/dL are considered prediabetic, and levels above 126 mg/dL on two separate occasions indicate diabetes. The result provided falls within the prediabetic range but does not indicate optimal glycemic control.
Correct Answer is A
Explanation
Choice A rationale:
A blood lead level of 18 mcg/dL in a 9-month-old infant is elevated. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 mcg/dL or higher in children to be concerning. Lead exposure can lead to developmental delays and cognitive impairments. Therefore, this result needs to be reported to the healthcare provider promptly.
Choice B rationale:
Hemoglobin level of 12 g/dL is within the normal range for a 9-month-old infant (11-15 g/dL) There is no need to report this result to the provider.
Choice C rationale:
Iron level of 74 mcg/dL is within the normal range for a 9-month-old infant (50-120 mcg/dL) There is no need to report this result to the provider.
Choice D rationale:
Hematocrit level of 35% is within the normal range for a 9-month-old infant (29-41%) There is no need to report this result to the provider.
