A client who weighs 65 kg receives a prescription for lorazepam 44 mcg/kg intravenously to be administered 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.)
The Correct Answer is ["1.4"]
Calculate the total dosage required: 44 mcg/kg * 65 kg = 2860 mcg. Convert mcg to mg: 2860 mcg ÷ 1000 = 2.86 mg.
Divide by concentration: 2.86 mg ÷ 2 mg/mL = 1.43 mL.
Considering the vial contains 2 mg/mL, the nurse should administer around 1.43 mL, which can be rounded to 1.4 mL.

Correct Answer is C
Explanation
The client with Addison's disease is experiencing weakness, confusion, and dehydration, which can be indicative of an adrenal crisis. The low sodium level (129 mEq/L) and low glucose level (54 mg/dl) further support this suspicion. An acute viral infection can trigger an adrenal crisis in individuals with Addison's disease.
Intravenous hydrocortisone, a glucocorticoid, is the treatment of choice for managing an adrenal crisis. It helps to replenish cortisol levels and stabilize the client's condition.
Hydrocortisone helps in restoring the body's stress response and regulating electrolyte and glucose levels.
A broad-spectrum antibiotic may be necessary if there is evidence of a bacterial infection, but it does not directly address the symptoms associated with Addison's disease.
Regular insulin is used for managing high blood glucose levels in conditions such as diabetes, but in this case, the client has low glucose levels, so insulin is not the appropriate intervention.
Potassium chloride is a medication used to treat low potassium levels (hypokalemia), but the client's potassium level is within the reference range (5.3 mEq/L). Therefore, potassium chloride is not indicated in this situation.
Correct Answer is D
Explanation
In this scenario, the client is experiencing difficulty falling asleep at night, fatigue, and daytime sleepiness. These symptoms may indicate that the client's exercise routine is impacting their sleep patterns. By asking the client for a description of their exercise schedule, the nurse can gather important information about the timing, intensity, and duration of the client's exercise regimen.
Exercise has numerous benefits for sleep and overall health, but the timing and intensity of exercise can affect sleep patterns differently for individuals. Vigorous exercise close to bedtime may increase alertness and make it harder for some people to fall asleep.
Therefore, understanding the client's exercise routine will help the nurse assess if the timing or intensity of the exercise is contributing to the sleep issues.
Based on the information gathered, the nurse can provide appropriate guidance. This may include adjusting the timing of exercise to earlier in the day, reducing the intensity of exercise closer to bedtime, or considering other factors that may be contributing to the sleep difficulties, such as caffeine intake, stress, or environmental factors.
