A doctor orders nine units /kg/hr for a Heparin infusion. The patient weighs 76 kg. You're supplied with a Heparin bag that reads 50 untis/mL. How many mL/hr will you administer? |Round your answer to the nearest tenths)
13 mL/hr
13.66 mL/hr
13.6 mL/hr
13.7 mL/hr
The Correct Answer is D
Given:
Ordered dose of Heparin: 9 units/kg/hr
Patient weight: 76 kg
Concentration of Heparin: 50 units/mL
Step 1: Calculate the total dose of Heparin:
Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg)
Total dose (units/hr) = 9 units/kg/hr x 76 kg
Total dose (units/hr) = 684 units/hr
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 684 units/hr / 50 units/mL
Infusion rate (mL/hr) = 13.68 mL/hr
Step 3: Round to the nearest tenth:
Infusion rate (mL/hr) ≈ 13.7 mL/hr

Correct Answer is A
Explanation
A) Nausea and vomiting:
Nausea and vomiting are common gastrointestinal side effects of ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID). Ibuprofen can irritate the stomach lining, leading to nausea, vomiting, or even gastritis and peptic ulcers with long-term use. This is a well-known side effect of NSAIDs, and clients are often advised to take the medication with food to reduce the risk.
B) Drowsiness:
While some individuals may experience fatigue or a mild sedative effect, it is not typically associated with ibuprofen. Other pain medications, such as opioids or certain antihistamines, are more likely to cause drowsiness, but this is rare for ibuprofen.
C) Blurred vision:
While serious side effects of NSAIDs can include vision changes (e.g., from elevated blood pressure or kidney dysfunction), blurred vision is not directly related to ibuprofen use. If blurred vision occurs, it is important to investigate other potential causes or conditions.
D) Increased heart rate:
Ibuprofen primarily affects the inflammatory pathways and the gastrointestinal system, and does not typically cause changes in heart rate. However, in rare cases, NSAIDs can lead to cardiovascular issues such as increased blood pressure, which could indirectly affect heart rate, but tachycardia is not a common or expected side effect.
Correct Answer is A
Explanation
A) They should not be abruptly stopped:
Beta blockers should not be abruptly discontinued because sudden withdrawal can lead to rebound hypertension, tachycardia, and even a risk of acute myocardial infarction (MI) in patients with heart disease. Gradual tapering is recommended to allow the body to adjust and avoid these adverse effects.
B) They are safe to take with herbal medications:
Herbal medications can interact with beta blockers and alter their effectiveness or increase the risk of side effects. For example, herbs like St. John's wort can decrease the effectiveness of beta blockers, while others like ginseng may increase the risk of side effects like high blood pressure. It is important to consult with a healthcare provider before taking any herbal supplements with beta blockers.
C) It isn't necessary to monitor lab results:
While beta blockers don't require regular lab tests for their direct effects, monitoring is important in certain patients, especially those with underlying conditions like heart failure, kidney disease, or diabetes. For example, monitoring renal function, electrolytes, and blood glucose may be necessary for patients who are taking other medications alongside beta blockers or who have coexisting conditions.
D) Taking over-the-counter medications is acceptable:
Many over-the-counter (OTC) medications can interact with beta blockers and affect their effectiveness or cause adverse effects. For example, decongestants (found in many cold medications) can raise blood pressure and counteract the effects of beta blockers.
