A client presents with a respiratory rate of 7/min.
The ABG results are: pH 7.22, PaCO2 68 mm Hg, HCO3 26 mEq/L, PaO2 78 mm Hg, and Oxygen saturation 80 Which interpretation is most accurate?

Identifying appropriate placement for infectious clients requires understanding transmission-based precautions. Tuberculosis is an airborne pathogen requiring specialized ventilation to prevent the spread of droplet nuclei. Knowledge of negative pressure systems and environmental safety standards is essential for preventing nosocomial transmission to others.

Choice A rationale

Placing a client with active tuberculosis in a semi-private room violates airborne precautions. This increases the risk of horizontal transmission to immunocompromised roommates via microscopic droplet nuclei that remain suspended in the air for several hours.

Choice B rationale

Airborne infection isolation rooms require a minimum of 6 to 12 air exchanges per hour. Exhausting air directly outdoors or through HEPA filters prevents contaminated air from recirculating into common hallways or other patient care areas.

Choice C rationale

Admission to an intensive care unit is reserved for hemodynamically unstable clients or those requiring advanced mechanical ventilation. Tuberculosis alone is not an indication for critical care unless the client exhibits acute respiratory failure or septic shock.

Choice D rationale

While proximity to the nurses' station allows for frequent observation, it does not address the physiological requirement for negative pressure ventilation. Standard medical-surgical rooms lack the engineering controls necessary to contain airborne bacilli within the specific room.

The clinical scenario involves a client experiencing neurological deficits from a transient ischemic attack who presents with specific pharmacological and chemical allergies. Applying knowledge of cross-sensitivity and radiopaque dye composition is essential to identify risks associated with iodine-based contrast media and morphine-codeine hypersensitivity.

Choice A rationale

Computed tomography scans with contrast utilize iodine-based dyes to enhance vascular visualization. Since the client has a documented iodine allergy, this order poses a significant risk of anaphylaxis or severe hypersensitivity reactions and requires urgent clarification with the provider.

Choice B rationale

Transient ischemic attacks are often linked to atherosclerosis and hypertension. A low-fat, low-cholesterol diet is a standard therapeutic intervention to manage lipid levels and prevent further plaque accumulation, making this a safe and appropriate non-pharmacological order.

Choice C rationale

Monitoring vital signs is a fundamental nursing responsibility during the acute phase of a neurological event. Frequent assessments help detect changes in blood pressure or heart rate, which are critical for maintaining cerebral perfusion and identifying potential deterioration.

Choice D rationale

Acetaminophen is a non-opioid analgesic that does not share chemical properties with morphine or codeine. Because it is not an opiate or salicylate, it is safe to administer for a headache in a patient allergic to opioids.
