The nurse is teaching a 68-year-old client with heart failure about taking Furosemide at home. Which statement by the client indicates a correct understanding of when to take this medication?
"I will take my Furosemide whenever I notice swelling in my legs."
"I should take my Furosemide in the morning to avoid waking up frequently at night to urinate."
"It doesn't matter what time I take my Furosemide as long as I take it with food."
"I will take my Furosemide at bedtime to prevent swelling overnight."
The Correct Answer is B
A. "I will take my Furosemide whenever I notice swelling in my legs.": Furosemide should be taken regularly as prescribed, not just in response to symptoms. Intermittent use can lead to inconsistent fluid management and worsening of heart failure.
B. "I should take my Furosemide in the morning to avoid waking up frequently at night to urinate.". Furosemide is a loop diuretic that increases urine output. Taking it in the morning helps avoid nocturia, improving sleep quality while maintaining its therapeutic effects.
C. "It doesn't matter what time I take my Furosemide as long as I take it with food.": While food may reduce gastric irritation, the timing of diuretics is important due to their impact on urination. Random timing can cause sleep disturbances or inadequate symptom control.
D. "I will take my Furosemide at bedtime to prevent swelling overnight.": Taking Furosemide at bedtime increases the risk of nocturia and disrupted sleep. It does not specifically target overnight swelling and is not recommended for nighttime dosing.

Correct Answer is ["150"]
Explanation
Total volume to be infused = 1200 mL
Total infusion time = 8 hours
- Calculate the flow rate in mL per hour (mL/hr):
Flow rate (mL/hr) = Total volume (mL) / Total infusion time (hours)
= 1200 mL / 8 hours
= 150 mL/hr
Correct Answer is A
Explanation
A. The safe and toxic plasma levels of the drug are very close to each other: A narrow therapeutic index means there is a small margin between the minimum effective concentration and the toxic concentration. Small dosing errors or individual variations in metabolism can lead to toxicity or subtherapeutic effects, requiring close monitoring.
B. The drug has a wide range between its effective dose and toxic dose: This describes a drug with a wide therapeutic index, which allows more flexibility in dosing without significant risk of toxicity. Narrow therapeutic index drugs are the opposite and require precise dosing.
C. The drug requires infrequent monitoring of serum levels: Medications with a narrow therapeutic index often require frequent serum level monitoring to ensure that the drug stays within the safe and effective range. This helps reduce the risk of adverse effects or treatment failure.
D. The drug has a high margin of safety in clinical use: A high margin of safety is characteristic of drugs with a wide therapeutic index. Narrow therapeutic index drugs have a low safety margin and pose higher risks if not carefully dosed and monitored.
