The nurse is caring for a patient diagnosed with tuberculosis in a hospital setting and must initiate airborne precautions. Which of the following is true related to airborne precautions?

The patient can share a hospital room with a roommate.

Use of a mask is not required.

Patients will be in a positive pressure airflow room.

Patients will be in a negative pressure airflow exchange room.

Answer and Explanation

The Correct Answer is D

Choice A reason: Sharing a room with a roommate is contraindicated for tuberculosis, as airborne precautions prevent droplet nuclei transmission. Tuberculosis spreads via inhalation, and a shared room increases infection risk for others, violating isolation protocols, per infection control and respiratory disease management standards.

Choice B reason: Not requiring a mask contradicts airborne precautions, as tuberculosis requires N95 respirators for healthcare workers to block droplet nuclei. Masks are essential to prevent inhalation of infectious particles, ensuring safety during patient contact, per tuberculosis-specific infection control guidelines.

Choice C reason: Positive pressure airflow rooms are used for immunocompromised patients to prevent infections, not for tuberculosis, which requires negative pressure to contain airborne particles. Positive pressure would spread infectious droplets, increasing transmission risk, contrary to airborne precaution requirements, per infection control engineering.

Choice D reason: A negative pressure airflow room is required for tuberculosis to prevent airborne droplet nuclei from escaping, containing infectious particles. This ensures safe isolation, protecting staff and patients by directing airflow inward, aligning with airborne precautions, per CDC tuberculosis infection control guidelines.

Correct Answer is A

Explanation

Choice A reason: The carotid pulse is used for unresponsive, non-breathing patients, as it is the most reliable central pulse, reflecting cardiac output during cardiac arrest. Its accessibility and strength make it ideal for rapid assessment, guiding CPR initiation, per ACLS and emergency assessment protocols.

Choice B reason: The apical pulse, assessed via auscultation, is impractical for an unresponsive, non-breathing patient, requiring time and equipment. In emergencies, the carotid pulse is faster and more reliable to confirm pulselessness, ensuring timely CPR, per cardiac arrest management guidelines.

Choice C reason: The radial pulse is peripheral and less reliable in cardiac arrest, as it may be absent due to poor perfusion. The carotid pulse better reflects central circulation, critical for assessing unresponsiveness and apnea, guiding immediate resuscitation efforts, per emergency care standards.

Choice D reason: The brachial pulse is used in infants or for blood pressure but is less accessible than the carotid in adults during arrest. The carotid provides a quick, reliable pulse check, ensuring rapid initiation of life-saving measures, per ACLS and pulse assessment protocols.

A. Use a fluorescent light source to assess the skin. B. Inspect the skin only if the Braden score indicates a risk. C. Avoid touching the skin during inspection. D. Look for skin color that is darker than surrounding areas.

Correct Answer is D

Explanation

Choice A reason: Using a fluorescent light source may not adequately reveal Stage I pressure ulcers in dark skin, as color changes are subtle. Natural or halogen light is preferred to detect darkening or erythema. Fluorescent light can distort pigmentation, reducing accuracy, per dermatological assessment techniques.

Choice B reason: Inspecting skin only if the Braden score indicates risk may miss early Stage I ulcers, which present as non-blanchable darkening in dark skin. Routine inspection is essential, as Braden scores predict risk but do not confirm ulcers, potentially delaying intervention, per pressure injury protocols.

Choice C reason: Avoiding touching the skin during inspection is inappropriate, as palpation detects warmth, induration, or non-blanching, key for Stage I ulcers in dark skin. Tactile assessment complements visual inspection, ensuring accurate identification of early tissue damage, per comprehensive skin assessment guidelines.

Choice D reason: Looking for skin darker than surrounding areas is the best approach for Stage I pressure ulcers in dark skin, as they present as non-blanchable hyperpigmentation rather than redness. This visual change indicates early tissue damage, guiding timely intervention to prevent progression, per pressure ulcer staging standards.
