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.)

Rationale

A. This action is important to prevent unauthorized access to medications by the client or other patients. However, this is not the priority

B. Soft drink cans can potentially be used to harm oneself or others (e.g., by smashing or as a cutting tool). Removing these items helps to reduce the risk of self-injury or harm to others.

C. This action is typically done to safely dispose of any items that may be considered biohazardous, such as used tissues, bandages, or any items contaminated with bodily fluids. It helps to maintain infection control and prevent exposure to potentially infectious materials.

D. In some mental health units, clients may not be allowed to have personal electronic devices due to concerns about confidentiality, safety, or potential disruption. Providing a unit-controlled telephone allows staff to monitor communication and ensure it is appropriate and supportive

Rationale

A. A. lung biopsy involves obtaining a tissue sample from the lung for microscopic examination. It is typically performed to diagnose conditions such as lung cancer or to investigate unusual findings seen on imaging studies. However, for a client with COPD experiencing increased shortness of breath, a lung biopsy is not typically indicated as a first-line investigation. It is more invasive and usually reserved for specific diagnostic purposes other than routine evaluation of COPD symptoms.

B. Antibody testing is used to detect antibodies specific to certain infections or autoimmune conditions. It is not typically used in the routine evaluation of COPD symptoms unless there is suspicion of a specific autoimmune or infectious cause contributing to exacerbations, which is less common in COPD compared to other conditions.

C. A. sweat test is used to diagnose cystic fibrosis (CF), a genetic disorder that affects the lungs and digestive system. It measures the amount of chloride in sweat, which is elevated in individuals with CF. Since COPD and CF are distinct conditions with different underlying causes and diagnostic criteria, a sweat test is not appropriate for evaluating COPD symptoms.

D. Spirometry is the most appropriate test to schedule for evaluating a client with COPD who reports increased shortness of breath with activity. Spirometry measures lung function by assessing how much and how quickly a person can move air into and out of their lungs. It provides valuable information about the severity of airflow limitation, which is characteristic of COPD.
