A nurse is preparing to administer intramuscular epinephrine to a client who is experiencing anaphylaxis. Which of the following sites should the nurse use?

A Sputum cultures for AFB are used to detect the presence of Mycobacterium tuberculosis, the bacteria causing TB. A negative result means that the sputum samples tested do not contain viable TB bacteria that can be transmitted to others. It indicates that the client's TB treatment has been effective in reducing the bacterial load to non-infectious levels.

B. The Quantiferon-TB Gold test is a blood test used to detect TB infection based on the immune response to TB antigens. A positive result indicates TB infection but does not differentiate between latent TB infection (not infectious) and active TB disease (potentially infectious).

C. The Mantoux tuberculin skin test (TST) is another test used to detect TB infection based on a delayed- type hypersensitivity reaction to TB antigens. An induration of less than 1 mm is considered negative and suggests that the client does not have a significant immune response to TB antigens, which could mean they are not infected with TB or the infection is not significant. This finding does not provide information on the client's infectiousness.

D. This indicates improvement in the client's symptoms, as coughing up blood-tinged sputum (hemoptysis) is a common symptom of active pulmonary TB. While improvement in symptoms is an important aspect of TB treatment, it does not directly indicate whether the client is no longer infectious. Infectiousness is primarily determined by microbiological tests such as sputum cultures for AFB.

A Pain typically occurs when the stomach is empty (1-3 hours after eating), often during the night and early morning. This pattern occurs because the presence of food helps to buffer gastric acid, whereas an empty stomach allows acid to directly contact the ulcerated area, leading to pain.

B. Pain in the right lower quadrant is not typically associated with peptic ulcer disease. Pain in PUD is usually located in the epigastric region (upper abdomen), although it can radiate to the back or other areas depending on the location and severity of the ulcer.

C. Constipation is not a typical finding in peptic ulcer disease. PUD is primarily associated with gastrointestinal symptoms related to acid-peptic imbalance, such as abdominal pain, bloating, nausea, and sometimes vomiting. Bowel habits are generally not directly affected by PUD.

D. In peptic ulcer disease, pain is usually relieved by eating or taking antacids. This is because food intake neutralizes gastric acid and provides a temporary protective coating over the ulcer, reducing irritation and pain.
