A patient weighing 132 lb is prescribed lorazepam 44 mcg/kg IV to be administered 20 minutes before a scheduled procedure.

The medication is available in a 2 mg/mL vial.

How many mL should the nurse administer? Round off to 2 d.p.

(This is a medical math nd does not require options.)

Choice A rationale

Uterine atony refers to a condition where the uterus fails to contract sufficiently during and after childbirth. This lack of contraction can lead to excessive bleeding, also known as postpartum hemorrhage. This is because the contractions of the uterus after delivery help to compress the blood vessels and prevent bleeding. Therefore, uterine atony can cause a patient to hemorrhage.

Choice B rationale

Wound dehiscence refers to a surgical complication where an incision reopens either internally or externally. It can cause pain, infection, and organ protrusion. However, it is not directly associated with hemorrhaging.

Choice C rationale

Infection refers to the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. While severe infections can lead to sepsis and disseminated intravascular coagulation, which can cause bleeding, they do not directly cause hemorrhaging.

Choice D rationale

Hemorrhage is a symptom, not a condition. It refers to excessive bleeding which can occur due to various conditions, including uterine atony.

Choice A rationale

Determining the amount of weight the patient has lost since increasing activity is relevant to the patient’s overall health and progress toward weight loss goals, but it does not directly address the issue of sleep difficulties. Weight loss and improved sleep may not always have a direct cause-and-effect relationship.

Choice B rationale

Inquiring about the patient’s exercise schedule is a reasonable action. It allows the nurse to gather information about the patient’s exercise routine and assess whether it might be contributing to the sleep difficulties. For instance, exercising too close to bedtime can interfere with sleep. Therefore, understanding the timing and intensity of the patient’s exercise can provide valuable insights into potential adjustments that could improve sleep quality.

Choice C rationale

Informing the patient that lifestyle changes often take several weeks to be effective is a general statement that might not address the specific concerns of the patient. While it’s true that lifestyle changes, including exercise, can take time to show results, this does not provide a targeted solution to the patient’s reported difficulty in falling asleep.

Choice D rationale

Encouraging the patient to exercise daily to reduce bedtime wakefulness is not appropriate advice in this scenario. It oversimplifies the issue and may not address the underlying causes of the patient’s sleep difficulties. Additionally, excessive exercise close to bedtime may actually interfere with sleep.
