A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

A. I can substitute one medication for another if I run out because they all fight infection.

B. I will wash my hands each time I cough.

C. I am glad I don't have to have any more sputum specimens.

D. I don't need to worry about where I go once I start taking my medications.

Correct Answer: B
Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.

To assess the kidney function of a patient with an indwelling urinary (Foley) catheter, the nurse measures the hourly urine output. When should she notify the physician?

• A. Less than 30 ml/hour
• B. 64 ml in 2 hours
• C. 90 ml in 3 hours
• D. 125 ml in 4 hours

Correct Answer: A
Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.

A client has had a cast applied, and a nurse is providing care. Which of the following actions should the nurse take first?

• A. Place an ice pack over the cast.
• B. Palpate the pulse distal to the cast.
• C. Teach the client to keep the cast clean and dry.
• D. Position the casted extremity on a pillow.

Correct Answer: Palpate the pulse distal to the cast.
Rationale: When caring for a client with a newly applied cast, the nurse's priority should be to assess the circulation by palpating the pulse distal to the cast. This is crucial to ensure there is no compromise in blood flow, which could lead to serious complications. Placing an ice pack over the cast, teaching the client about cast care, and positioning the casted extremity on a pillow are important interventions but should follow the assessment of circulation.

All of the following statements are true about donning sterile gloves except:

• A. The first glove should be picked up by grasping the inside of the cuff.
• B. The second glove should be picked up by inserting the gloved fingers under the cuff outside the glove.
• C. The gloves should be adjusted by sliding the gloved fingers under the sterile cuff and pulling the glove over the wrist.
• D. The inside of the glove is considered sterile.

Correct Answer: D
Rationale: When donning sterile gloves, it is essential to maintain sterility. The correct way to don sterile gloves includes grasping the outside of the cuff to put on the first glove and inserting the gloved fingers under the cuff outside the glove to put on the second glove. Adjustments should be made by sliding the fingers under the sterile cuff. It is crucial to remember that once the inside of the glove is touched during the donning process, it is no longer considered sterile.

During a seizure, what is the primary intervention?

• A. Protect the patient from injury
• B. Insert an airway
• C. Elevate the head of the bed
• D. Withdraw all pain medications

Correct Answer: A
Rationale: The primary intervention during a seizure is to protect the patient from injury. This involves creating a safe environment by moving harmful objects away, cushioning the head, and staying with the patient until the seizure ends. Inserting an airway is only necessary if the patient's airway is obstructed, not routinely during a seizure. Elevating the head of the bed is not a priority during an active seizure as it won't affect the seizure's outcome. Withdrawing all pain medications is not a standard practice unless there are specific contraindications related to the seizure itself.
