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 D
Explanation
A. A 12-year-old reporting neck, arm, and lower back discomfort:
- This child is reporting discomfort, which is concerning, but it doesn't indicate an immediate life-threatening condition. However, a thorough assessment is needed to rule out any serious injuries, especially to the spine.
B. An 8-year-old with a full leg air splint for a possible broken tibia:
- While a possible broken tibia requires attention, it is not as immediately critical as symptoms such as projectile vomiting. Splinting can help stabilize the limb, but it is not an emergency that requires immediate attention compared to potential neurological issues.
C. A 6-year-old with multiple superficial lacerations of all extremities:
- Superficial lacerations, although they require care, are generally not immediately life-threatening. The child needs appropriate wound care and assessment for any deeper injuries, but this can be addressed in a timely manner without immediate urgency.
D. An 11-year-old with a headache, nausea, and projectile vomiting:
- This is the most concerning presentation among the options. Headache, nausea, and projectile vomiting could be indicative of a severe head injury, and these neurological symptoms require urgent evaluation to assess for conditions such as a concussion, intracranial bleed, or increased intracranial pressure.
Correct Answer is ["B","C","D","G","H"]
Explanation
- Capillary refill: This is a quick and simple way to assess the adequacy of peripheral perfusion and can help identify signs of dehydration.
- Skin turgor: Assessing the skin turgor, or the elasticity of the skin, is another useful indicator of dehydration.
- Heart rate: Tachycardia can be a sign of dehydration, so monitoring the heart rate is an important component of the assessment.
- Blood pressure: Blood pressure can be affected by dehydration, so monitoring it is important in determining the severity of dehydration and in guiding appropriate interventions.
- Temperature: Fever is a potential cause of dehydration, so monitoring the temperature is an important part of the assessment.
- Skin color of hands and feet: Checking the color of the skin on the hands and feet can help identify signs of poor perfusion and dehydration.
Assessing the level of consciousness, pupil size and reactiveness, and respiratory rate are important aspects of the neurological and respiratory assessments but are not specific to the assessment of dehydration.
