A nurse is preparing to administer cefazolin 1 g by intermittent IV bolus over 30 min. Available is cefazolin 1 g in 100 mL dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A random stool specimen is a non-invasive diagnostic procedure used to detect pathogens, occult blood, or fecal fat content. Proper collection technique prevents contamination from urine or external chemicals, ensuring the diagnostic validity of the laboratory analysis. The nurse must provide clear instructions on the use of personal protective equipment and the safe disposal of biohazardous materials to prevent nosocomial transmission.

Rationale:

A. The introduction of chemical agents like chlorhexidine into the collection container is contraindicated because it alters the specimen’s composition. Disinfectants can kill the very microorganisms the laboratory is attempting to culture, leading to false-negative results. The commode should be clean and dry, free from all detergents or antiseptic solutions.

B. Specimens should never be stored in a refrigerator that contains medication or food due to the risk of cross-contamination. Facility protocols require a dedicated, labeled biohazard refrigerator for the temporary storage of laboratory samples. Proper placement ensures that pharmaceutical integrity is maintained while following strict infection control guidelines.

C. Collecting specific components like pus with a sterile swab is an advanced technique typically reserved for culture and sensitivity testing. For a random stool specimen, the UAP should collect a representative sample of the stool itself rather than focusing on exudates. Advanced specimen retrieval often requires licensed nursing judgment to ensure proper sampling.

D. Used tongue blades are considered contaminated waste and must be handled to prevent the spread of enteric pathogens. Wrapping them in a paper towel before placing them in the biohazard receptacle reduces the risk of accidental contact for environmental services staff. This practice maintains a clean environment and adheres to standard precautions for fecal matter.

Dementia-related agitation often stems from unmet needs or environmental overstimulation, necessitating a focus on safety and physical integrity. Before implementing mechanical immobilization, a thorough physical assessment is mandatory to establish a baseline and prevent iatrogenic injury. The nurse must prioritize the protection of cutaneous tissues, as frail elderly patients are highly susceptible to pressure-related trauma and localized ischemia during restrictive interventions.

Rationale:

A. Securing the device to the bed frame with a quick-release knot is a vital safety step during the actual application process. However, the nurse must complete a thorough pre-application assessment of the patient's physical status before initiating the tethering process. Ensuring the knot is accessible allows for rapid removal during a clinical emergency or fire.

B. Verifying that the vest is oriented correctly with the opening at the posterior prevents the risk of accidental strangulation or restricted thoracic expansion. While correct orientation is essential for device efficacy, it follows the initial assessment of the patient's skin and underlying physical condition. Proper fit ensures the device functions as intended without causing secondary physical harm.

C. Inspecting the skin is the highest priority to ensure there are no existing lesions or areas of compromised circulation before restraint. Applying a vest over damaged tissue can lead to rapid necrosis or exacerbate underlying skin breakdown due to friction and pressure. Documentation of the skin’s integrity provides a critical baseline for ongoing monitoring and legal compliance.

D. Maintaining adequate space between the patient and the material ensures that respiratory excursion and peripheral circulation are not impeded. While the "two-finger" or "four-finger" rule is a standard evaluative measure after the vest is on, it is a component of fitting rather than the initial assessment. The nurse must first ensure the site is healthy enough to tolerate the device.
