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.)

These are important safety and comfort measures for a client who uses home oxygen therapy via a nasal cannula.

The other options are not correct because:

b. Verify the oxygen flow rate every other day. This is not frequent enough, as the flow rate should be checked at least daily and whenever the client feels short of breath or has changes in vital signs.

d. Apply petroleum ointment to nares if they become dry and irritated. 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.

Answer: A, B D

Rationale:

• Albuterol is a bronchodilator, and one of its key effects is to relax the muscles around the airways, which helps prevent wheezing. Wheezing is often caused by narrowed airways, and by opening them, albuterol helps to prevent this sound, which is associated with asthma or other respiratory conditions.

• B. The medication will decrease coughing episodes:
  Albuterol can help decrease coughing in individuals with conditions like asthma or chronic obstructive pulmonary disease (COPD) by relaxing the muscles in the airways, which reduces airway constriction. Since coughing often occurs due to airway obstruction, albuterol’s bronchodilator effect can help alleviate this symptom.

• C. The medication will reduce inflammation: Albuterol does not have anti-inflammatory properties. Its primary mechanism is bronchodilation, and anti-inflammatory treatment generally requires corticosteroids, not beta-agonists like albuterol.

• D. The medication will open the airways:
  This is correct. Albuterol works as a bronchodilator, meaning it opens up the airways by relaxing the smooth muscles surrounding them. This improves airflow and makes breathing easier, which is why it is often used in conditions like asthma or COPD.

• E. The medication will stimulate flow of mucus: Albuterol does not stimulate mucus production; it primarily works by relaxing the airways. However, by improving airflow, it can help clients more effectively expel mucus through coughing.
