A nurse is preparing to administer digoxin 2 mcg/kg/day PO to divide equally every 12 hours for an infant who weighs 7 kg. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.14"]
Step 1: Identify the known values
- Dose ordered = 2 mcg/kg/day
- Frequency = every 12 hours → 2 doses per day
- Weight = 7 kg
- Concentration available = 0.05 mg/mL
Step 2: Calculate total daily dose in mcg
2 mcg × 7 kg = 14 mcg/day
Step 3: Divide daily dose by 2 to get per dose
14 mcg ÷ 2 = 7 mcg per dose
Step 4: Convert mcg to mg
7 mcg = 0.007 mg
Step 5: Use concentration to calculate mL per dose
0.007 mg ÷ 0.05 mg/mL = 0.14 mL
Answer: 0.14 mL

Correct Answer is ["A","B","C","D"]
Explanation
A. Perioperative antibiotics is correct. The benchmark is 100%. Performance was 90.4% in Q1, 88.2% in Q2, and 92.6% in Q3, all of which are below the benchmark, indicating noncompliance.
B. Smoking cessation is correct. The benchmark is 75%. While Q2 reached 100%, Q1 (70.6%) and Q3 (74%) were both below the benchmark, showing inconsistent compliance.
C. Glucose control is correct. The benchmark is 90%. All quarters were below the benchmark: Q1 (75.2%), Q2 (85.5%), and Q3 (82%).
D. Post operative normothermia is correct. The benchmark is 85%. Q1 (69%) fell below the benchmark, although Q2 and Q3 met or exceeded it. Still, any quarter below the benchmark signals an area for improvement.
E. Intraoperative vancomycin is incorrect. The benchmark is 80.2%. While Q1 (75.7%) fell slightly below the benchmark, Q2 (80.5%) and Q3 (92%) met or exceeded it, indicating overall adequate performance and improvement over time.
Correct Answer is B
Explanation
A. Polyphagia is incorrect. Polyphagia (excessive hunger) is typically associated with diabetes mellitus, not diabetes insipidus. In diabetes insipidus, the primary issue is excessive thirst and urination, rather than increased appetite.
B. Dehydration is correct. Diabetes insipidus causes the kidneys to excrete large volumes of dilute urine, leading to dehydration. Clients with this condition may experience excessive thirst (polydipsia) and urinate large amounts of water, leading to dehydration if fluid intake doesn't keep up with the loss.
C. Bradycardia is incorrect. Bradycardia (slow heart rate) is not a typical finding in diabetes insipidus. On the contrary, dehydration resulting from excessive urination could lead to tachycardia (increased heart rate) as a compensatory mechanism.
D. Hyperglycemia is incorrect. Hyperglycemia (high blood glucose) is characteristic of diabetes mellitus, not diabetes insipidus. In diabetes insipidus, blood glucose levels are typically normal since the condition does not involve insulin or glucose metabolism.
