A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DSW). The nurse should set the pump to deliver how many mL/hr?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.

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.
