A nurse is caring for a client who is 5 hours postoperative following a transurethral resection of the prostate (TURP). The nurse notes that the client's indwelling urinary catheter has not drained in the past hour. Which of the following actions should the nurse take first?

Choice A reason:
While gargling with warm saline can provide symptomatic relief for a sore throat, it does not address the underlying bacterial infection. Therefore, it is not the priority action once a diagnosis of group A streptococcus has been confirmed.

Choice B reason:
Identifying close contacts is important for public health tracking and potentially preventing the spread of the infection. However, the immediate priority for the client is the initiation of treatment to address the infection.

Choice C reason:
Taking antipyretics can help manage fever and provide comfort to the client. While managing symptoms is important, it is secondary to initiating antibiotic therapy, which addresses the cause of the symptoms.

Choice D reason:
The priority action is to notify the client to return to the clinic for initiation of antibiotic therapy. Group A streptococcus is a bacterial infection that requires antibiotics for treatment. Prompt initiation of antibiotics is crucial to prevent complications and promote recovery.

Choice A Reason:
A 10 mm wheal is not indicative of TB infection. A wheal is a raised, often itchy area of skin that usually signifies an allergic reaction, not an infection. The TST looks for induration, which is a firm swelling, as a sign of TB infection.

Choice B Reason:
A 5 mm induration is considered positive in certain high-risk groups, such as people living with HIV, recent contacts of TB patients, or those with a history of organ transplants. For individuals without these risk factors, a 5 mm induration is not considered a positive result.

Choice C Reason:
A 15 mm induration is considered a positive TST result for individuals with no known risk factors for TB. This indicates that the person's immune system has reacted to the tuberculin purified protein derivative (PPD) injected under the skin, suggesting exposure to TB bacteria.

Choice D Reason:
Erythema, or redness of the skin, is not measured when interpreting TST results. The test measures induration, which is a palpable, raised, hardened area or swelling. Therefore, a 4 mm erythema does not indicate TB infection.
