Which nursing assessment indicates a positive reading of a tuberculin (TB) skin test?

A. Place tissue soiled with respiratory secretions in a paper bag for later disposal:

This instruction is not accurate or recommended for managing tissue soiled with respiratory secretions, particularly in the context of tuberculosis (TB) infection. TB is transmitted through the air via respiratory droplets, so proper disposal of contaminated materials is crucial to prevent the spread of the infection. Instead of placing tissue in a paper bag, it should be disposed of in a sealed plastic bag to minimize the risk of transmission. Additionally, individuals with TB should be instructed on proper respiratory hygiene practices, such as covering their mouth and nose with a tissue or their elbow when coughing or sneezing, to prevent the spread of infectious droplets.

B. Provide samples for sputum cultures every 6 weeks:

Sputum cultures are an essential component of monitoring and managing tuberculosis (TB) treatment. However, obtaining samples every 6 weeks is not frequent enough, especially during the initial phase of treatment. In the early stages of TB treatment, sputum cultures are typically obtained more frequently, often weekly or biweekly, to monitor the response to treatment, assess for drug resistance, and ensure treatment effectiveness. As treatment progresses and the patient's condition stabilizes, the frequency of sputum cultures may be adjusted based on clinical judgment and guidelines.

C. Consume alcohol in moderation while taking antituberculosis medications:

Alcohol consumption is generally discouraged while taking antituberculosis medications. Some antituberculosis drugs, such as isoniazid and rifampin, can interact with alcohol and cause adverse effects, such as liver toxicity or drug metabolism issues. Therefore, individuals undergoing treatment for tuberculosis should be advised to abstain from alcohol consumption or limit it to a minimum to avoid potential complications. Providing instructions on alcohol consumption is an important aspect of tuberculosis management and medication adherence.

D. Wear a mask while out or around crowds of people:

This instruction is crucial for individuals with pulmonary tuberculosis to prevent the spread of the infection to others. Tuberculosis is transmitted through the air via respiratory droplets, particularly when an infected person coughs, sneezes, or talks. Wearing a mask while out or in crowded settings helps reduce the risk of transmitting infectious droplets to others and is an important infection control measure. It is especially important during the early stages of treatment when the individual is still infectious and shedding bacteria. Proper mask use, along with other respiratory hygiene practices, can help protect both the individual with tuberculosis and those around them from the spread of infection.

A. Air moves in and out of a wound in the chest wall.

In an open pneumothorax, also known as a sucking chest wound, there is a communication between the pleural space and the external environment through a wound in the chest wall. This allows air to move freely in and out of the pleural cavity during respiration. As a result, there is a loss of negative pressure within the pleural space, impairing lung expansion and leading to respiratory compromise. This condition is considered a medical emergency and requires prompt intervention to prevent tension pneumothorax and respiratory failure.

B. Air cannot pass freely into the thoracic cavity through a chest wound.

In an open pneumothorax, air can pass freely into the thoracic cavity through the chest wound. This communication between the external environment and the pleural space results in air movement in and out of the wound during respiration.

C. There are no audible sounds in an open pneumothorax.

In an open pneumothorax, there may be audible sounds, such as sucking or hissing sounds, particularly during inspiration. These sounds occur due to the movement of air in and out of the chest wound and can be indicative of the condition.

D. The air is trapped when it enters the cavity.

In an open pneumothorax, the air is not trapped when it enters the pleural cavity. Instead, air moves freely in and out of the wound in the chest wall, leading to respiratory compromise and potential progression to tension pneumothorax if left untreated.
