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.)

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.

A humidifier bottle adds moisture to the oxygen, which prevents drying and irritation of the nasal mucosa

and enhances gas exchange.

a. Remove the nasal cannula while the client eats. This is not advisable, as the client may become hypoxic during eating, especially if they have pneumonia and impaired lung function. The nurse should monitor the client's oxygen saturation and respiratory status during meals and adjust the oxygen delivery device as needed.

c. Secure the oxygen tubing to the bed sheet near the client's head. This is not safe, as it can cause entanglement, dislodgement, or kinking of the tubing, which can compromise oxygen delivery and cause injury to the client.

d. Apply petroleum jelly to the nares as needed to soothe mucous membranes. This is not recommended, as petroleum products can ignite in the presence of oxygen and cause burns or fire. A water-based lubricant should be used instead.
