A client who weighs 132 lb receives a prescription for lorazepam 44 mcg/kg IV to be administer 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer?

(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

Convert pounds to kilograms.

1 pound = 0.453592 kilograms
132 pounds * 0.453592 kg/pound = 59.87 kilograms

Step 2: Calculate the total dose in micrograms.

44 micrograms/kilogram * 59.87 kilograms = 2635.08 micrograms

Step 3: Convert micrograms to milligrams.

1 milligram = 1000 micrograms
2635.08 micrograms / 1000 micrograms/milligram = 2.63508 milligrams

Step 4: Calculate the volume to be administered.

Concentration of lorazepam = 2 milligrams/milliliter
Volume = Dose / Concentration
Volume = 2.63508 milligrams / 2 milligrams/milliliter = 1.31754 milliliters

Therefore, the nurse should administer approximately 1.3 milliliters of the lorazepam solution.

A. I should have taken an extra dose of fluticasone- salmeterol. B. I should have taken some allergy medications before going on the hike. C. I have been very stressed out lately and should work on stress management. D. I should have eaten a snack halfway through the hike. E. My friend smoked cigarettes during the hike

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"A"}}

Explanation

Correct choices are;

A.I should have taken an extra dose of fluticasone-salmeterol -No Understanding
Explanation: Fluticasone/salmeterol is a long-acting inhaler used for maintenance therapy in asthma. It is not meant to be used as a rescue medication for acute symptoms or exacerbations. Therefore, taking an extra dose in response to symptoms would not be appropriate.

B. I should have taken some allergy medications before going on the hike -Understanding
Explanation: Allergy medications, such as antihistamines or nasal sprays, can help reduce allergic triggers that can exacerbate asthma symptoms. Taking these medications before exposure to known triggers (like allergens during a hike) can help prevent an asthma exacerbation.

C. I have been very stressed out lately and should work on stress management -Understanding
Explanation: Stress is a known trigger for asthma exacerbations. Managing stress through techniques such as relaxation exercises, mindfulness, or therapy can help reduce the likelihood of triggering asthma symptoms.

D. I should have eaten a snack halfway through the hike - No Understanding
Explanation: While maintaining good nutrition and hydration is important for overall health, eating a snack would not necessarily prevent an asthma exacerbation unless the snack contained medications or substances that specifically manage asthma symptoms.

E. My friend smoked cigarettes during the hike - Understanding
Explanation: Secondhand smoke is a common trigger for asthma exacerbations. Being exposed to cigarette smoke can irritate the airways and worsen asthma symptoms.
