A nurse is caring for a client who comes to the clinic to be tested for tuberculosis (TB) after a close family contact tests positive. Which of the following measures should the nurse anticipate preparing for this client?
Bacille Calmette-Guérin (bCG) vaccine
Chest x-ray
Sputum culture for acid fast bacillus (AFB)
Tuberculin skin test
The Correct Answer is D
A. The BCG vaccine is a vaccine used to prevent tuberculosis (TB) disease. However, its effectiveness varies widely and is primarily used in countries with a high prevalence of TB. Therefore, administering the BCG vaccine is not typically part of the evaluation process for TB exposure in a client.
B. A chest x-ray is commonly used to evaluate for active pulmonary TB disease. It can identify characteristic findings such as infiltrates, cavitations, or nodular lesions in the lungs that suggest TB infection. A chest x- ray is often performed as part of the initial evaluation for TB after exposure or to assess for active disease.
C. Sputum culture for AFB is a definitive diagnostic test for tuberculosis. It involves collecting sputum samples and culturing them in a laboratory to detect the presence of Mycobacterium tuberculosis, the bacterium that causes TB.
D. The tuberculin skin test (TST), also known as the Mantoux test, involves injecting a small amount of purified protein derivative (PPD) into the skin of the forearm. After 48-72 hours, a healthcare provider assesses the size of the induration (swelling) at the injection site. A positive TST indicates exposure to TB but does not differentiate between latent TB infection (LTBI) and active TB disease.

Explanation
To administer a dose of 10 mg of olanzapine using 5 mg tablets, the nurse would need to give two (2) tablets
Correct Answer is A
Explanation
A. This option is aimed at modifying the consistency of fluids to make them easier to swallow for someone with dysphagia. Thickened liquids are often recommended to prevent aspiration (when food or liquid enters the airway instead of the esophagus) in patients with swallowing difficulties.
B. Placing food on the unaffected side of the mouth, which would be the right side in the case of left-sided weakness, is recommended to aid in easier chewing and swallowing.
C. Temperature can affect how easily food can be swallowed and enjoyed by someone with dysphagia. Extremely hot or cold foods can be more challenging to swallow. However, this dose not address the risk of aspiration.
D. Tipping the head back during swallowing is not recommended because it can increase the risk of choking or aspiration. Instead of tilting the head back, clients with dysphagia should be instructed to maintain an upright position when eating and drinking.
