A nurse is assessing a client for hypoxemia during an asthma attack. Which of the following manifestations should the nurse expect?

Answer: B

Rationale:

A) "Expect your sputum cultures to be negative after 6 months of therapy":

While sputum cultures may become negative after a period of effective therapy, it is not always guaranteed to happen within exactly 6 months. Tuberculosis (TB) treatment usually involves several months of medication, and sputum cultures are monitored periodically to assess treatment efficacy, not solely at the 6-month mark.

B) "Drink at least 8 ounces of water when you take the pyrazinamide tablet":

Drinking plenty of water with pyrazinamide is important to prevent dehydration and to help minimize potential side effects, such as hyperuricemia or gout. Adequate hydration can also aid in the effective elimination of the medication from the body, thus reducing the risk of adverse effects.

C) "Provide a sputum specimen every 2 weeks to the clinic for testing":

Sputum specimens are typically provided less frequently than every 2 weeks, usually monthly, to monitor the progress of TB treatment. Testing frequency may vary depending on the client's condition and the healthcare provider's recommendations.

D) "Take isoniazid with an antacid":

Isoniazid should not be taken with antacids, as antacids can interfere with the absorption of isoniazid. It is usually advised to take isoniazid on an empty stomach, and clients should be instructed to wait at least 1 hour after taking isoniazid before consuming antacids.

Heparin is an anticoagulant that prevents the formation of new clots and the extension of existing clots. It is the drug of choice for treating acute pulmonary embolism, which is a life-threatening condition caused by a blood clot that travels to the lungs and blocks a pulmonary artery.

a) Dexamethasone is a corticosteroid that reduces inflammation and suppresses immune response. It is not indicated for treating pulmonary embolism, but it may be used for other pulmonary conditions, such as asthma or COPD.
b) Atropine is an anticholinergic that blocks the action of acetylcholine and increases heart rate and cardiac output. It is not indicated for treating pulmonary embolism, but it may be used for bradycardia or asystole.
d) Furosemide is a loop diuretic that increases urine output and reduces fluid volume and blood pressure. It is not indicated for treating pulmonary embolism, but it may be used for heart failure or edema.
