ATI Fundamentals

Correct Answer: D

Rationale: The client's presentation with an SaO2 of 91%, audible wheezes, and use of accessory muscles indicates respiratory distress, likely due to bronchoconstriction. Beta2 agonists are the appropriate class of medications to administer in this situation as they act as bronchodilators, helping to relieve the bronchoconstriction and improve airflow to the lungs. Antibiotics, beta-blockers, and antivirals are not indicated for this client's respiratory distress symptoms.

Correct Answer: C

Rationale: Stripping the drainage tubing is an outdated practice and can cause complications. Encouraging the client to cough helps with lung expansion, checking for continuous bubbling ensures proper functioning of the chest tube system, and obtaining a chest x-ray helps to assess the position of the chest tube and re-expansion of the lung. Therefore, stripping the drainage tubing every 4 hours should not be included in the plan of care.

Correct Answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

Correct Answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

Correct Answer: B

Rationale: Avocados contain high levels of tyramine, which can cause a hypertensive crisis when consumed with phenelzine, a monoamine oxidase inhibitor (MAOI). It is essential for clients taking MAOIs to avoid foods rich in tyramine to prevent dangerous interactions and potential health risks.
