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
A) Incorrect- While physical soothing can help comfort the child after the injections, it may not significantly reduce the duration of pain during the injections themselves.
B) Incorrect- Verbal reassurance is important to provide a calming environment, but it may not directly reduce the duration of pain during the injections.
C) Correct- Administering vaccines can be distressing for toddlers due to the pain associated with injections. To reduce the duration of pain and minimize the overall discomfort, the nurse should prioritize the strategy of simultaneous injections. This involves administering multiple vaccines at the same time rather than spacing them out. The rationale behind this approach is that the child experiences the discomfort of the injections only once, which can help reduce their overall distress and anxiety.
D) Incorrect- The positioning of the child may not have a direct impact on the duration of pain during injections. However, choosing an appropriate position for comfort is still important.
Correct Answer is D
Explanation
Choice A rationale: White blood cell count monitors for infection or inflammation. While important for general health, it does not address the massive fluid loss and electrolyte imbalances specifically caused by diabetes insipidus.
Choice B rationale: Capillary glucose monitors for diabetes mellitus. Diabetes insipidus involves antidiuretic hormone deficiency, not insulin issues; therefore, glucose levels are not the priority in managing the massive dilute polyuria seen here.
Choice C rationale: Urine specific gravity will be consistently low in diabetes insipidus. While it confirms the diagnosis of dilute urine, it is less critical than monitoring the life-threatening systemic effects of dehydration.
Choice D rationale: Serum sodium is the most important lab to monitor. Massive loss of dilute urine leads to severe hemoconcentration and hypernatremia, which can cause cerebral edema, seizures, and permanent neurological damage.
