CALCULATE FLOW RATES IN DROPS PER MINUTES: Order: Zosyn 1.3 g in 100 mL D5W IVPB 98h to infuse over 30 min. Drop factor: 60 gtt/mL. Determine rate in gtt/min.
400 gtt/min
100 gtt/min
200 gtt/min
150 gtt/min
The Correct Answer is C
Given:
Volume of fluid: 100 mL
Infusion time: 30 minutes
Drop factor: 60 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min) x Drop factor (gtt/mL)
Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 100 mL / 30 min
Infusion rate (mL/min) = 3.33 mL/min
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 3.33 mL/min x 60 gtt/mL
Flow rate (gtt/min) = 200 gtt/min

Correct Answer is A
Explanation
A) Potassium level of 3.0 mEq/L:
A potassium level of 3.0 mEq/L is below the normal range (3.5-5.0 mEq/L) and indicates hypokalemia. This is a critical finding for a patient taking digoxin. Hypokalemia increases the risk of digoxin toxicity because low potassium levels enhance the action of digoxin on the heart, potentially leading to arrhythmias. Therefore, the nurse should immediately report this finding to the provider for correction of the potassium imbalance.
B) BP of 132/82 mm Hg:
A blood pressure of 132/82 mm Hg is within the normal to slightly elevated range for adults. There is no immediate cause for concern related to the administration of digoxin, as this value is not indicative of hypotension or any immediate contraindication.
C) Digoxin level of 1.2 ng/mL:
A digoxin level of 1.2 ng/mL is within the therapeutic range (0.5-2.0 ng/mL). There is no indication that this level would need to be reported, as it is appropriate for digoxin therapy and not indicative of toxicity.
D) Heart rate of 66/min:
A heart rate of 66/min is within the normal range for an adult at rest (60-100 bpm). A heart rate below 60 bpm may warrant further assessment when taking digoxin, as it can cause bradycardia. However, a heart rate of 66 is not alarming and does not necessitate reporting to the provider, as it is still within an acceptable range for most individuals.
Correct Answer is ["B","C","D","E"]
Explanation
A) Anticoagulants:
Anticoagulants, such as warfarin, heparin, and direct oral anticoagulants (DOACs), are specifically designed to prevent the formation of blood clots or to treat existing clots. They work by interfering with various stages of the clotting cascade, either by inhibiting clotting factors or by enhancing the effects of natural anticoagulants in the body.
B) Antihypertensives:
Antihypertensives, such as ACE inhibitors, beta blockers, and calcium channel blockers, are used to lower high blood pressure by relaxing blood vessels, reducing heart rate, or decreasing fluid retention. While antihypertensives can reduce the overall strain on the heart and blood vessels, they do not have an impact on the clotting process and are not designed to interfere with blood coagulation.
C) Antibiotics:
Antibiotics, such as penicillin or amoxicillin, target bacteria and prevent their growth or kill them, but they do not affect the clotting mechanisms in the blood.
D) Antipyretics:
Antipyretics, such as acetaminophen (Tylenol) or ibuprofen, work by lowering the body's set point temperature in the hypothalamus, helping to relieve fever. They do not affect the clotting cascade or the ability of blood to form clots, so antipyretics are a correct answer.
E) Antiemetics:
Antiemetics, such as ondansetron or metoclopramide, are used to prevent or treat nausea and vomiting. They primarily work by blocking the receptors in the brain that trigger nausea and vomiting but do not have an effect on the clotting process. Thus, antiemetics are a correct answer.
