A nurse is reviewing the laboratory results of a client who is taking amitriptyline. Which of the following laboratory values should to the provider?
Potassium 4.2 mEq/L
Total bilirubin 1.5 mg/dL
WBC count 5.000/mm²
Hct 44
The Correct Answer is B
A. Potassium 4.2 mEq/L: While potassium levels should be monitored during amitriptyline therapy, the value of 4.2 mEq/L is within the normal range. There is no immediate concern based on this potassium level.
B. Total bilirubin 1.5 mg/dL
Amitriptyline, a tricyclic antidepressant, can sometimes cause hepatotoxicity, which may manifest as elevated liver enzymes or bilirubin levels. Therefore, any abnormality in liver function tests, such as total bilirubin, should be reported to the provider for further evaluation and management.
C. WBC count 5,000/mm³: The white blood cell count is not a commonly monitored parameter for amitriptyline, and the value of 5,000/mm³ is within the normal range. There is no immediate concern based on this WBC count.
D. Hct 44: The hematocrit (Hct) level is related to the percentage of red blood cells in the blood. A value of 44% falls within the normal range for hematocrit. There’s no immediate concern related to amitriptyline use based on this result either.

Correct Answer is ["A","C"]
Explanation
A. Absence of deep-tendon reflexes:
Absence of deep-tendon reflexes is a sign of magnesium toxicity. Magnesium sulfate, when infused in high doses, can lead to neuromuscular blockade and affect reflexes. Discontinuing the infusion and administering calcium gluconate can counteract the effects of magnesium.
B. Urine output 80 mL in 4 hours:
Urine output is not a direct indicator of magnesium toxicity. Monitoring urine output is important for assessing renal function, but it is not a specific sign of magnesium toxicity.
C. Decreased level of consciousness:
Decreased level of consciousness is another sign of magnesium toxicity. Central nervous system depression is a potential adverse effect of elevated magnesium levels. Administering calcium gluconate can help antagonize the effects of magnesium.
D. Report of chills:
Chills are not typically associated with magnesium toxicity. This symptom may indicate other issues, such as infection or discomfort.
E. Systolic blood pressure 130 mm/Hg:
Systolic blood pressure within a normal range is not a sign of magnesium toxicity. Blood pressure changes are not typically the primary indicators of magnesium toxicity.
Correct Answer is C
Explanation
A. A client received 0900 medications at 0930:
This situation involves a medication administration error where the medications were administered later than the scheduled time. An incident report should be completed to document the error, investigate the circumstances, and implement measures to prevent recurrence.
B. A client who has asthma was administered tiotropium via inhalation:
Tiotropium is an appropriate medication for asthma. As long as it was administered according to the prescribed guidelines, there is no need for an incident report.
C. A client received a blood transfusion with dextrose 5% in water:
This situation involves a significant medication error, as dextrose 5% in water is not the appropriate solution for a blood transfusion. An incident report should be completed to document the error, investigate the circumstances, and implement measures to prevent recurrence.
D. A client received an infusion of lipids through a central line:
If the infusion of lipids through a central line was ordered and administered appropriately, there is no need for an incident report. Lipid infusions are commonly administered through central lines when indicated.
