A nurse is assessing a patient who has acute respiratory distress syndrome (ARDS). Which of the following findings should the nurse expect?
Impaired carbon dioxide elimination due to shunting.
Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch.
Hypoxemia due to dead space.
Decreased pulmonary compliance due to stiffness.
Correct Answer : A,D
Choice A rationale
In ARDS, impaired carbon dioxide elimination due to shunting can occur. Shunting refers to the diversion of blood from areas of the lung that are ventilated to areas that are not, leading to impaired gas exchange.
Choice B rationale
Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch is not a typical finding in ARDS3.
Choice C rationale
Hypoxemia due to dead space is not a typical finding in ARDS. Dead space refers to areas of the lung that are ventilated but not perfused.
Choice D rationale
Decreased pulmonary compliance due to stiffness is a typical finding in ARDS. The lungs become stiff and less compliant due to the accumulation of fluid and inflammatory cells in the alveoli and interstitial space.

Correct Answer is A
Explanation
Choice A rationale
The hospital pharmacist is the most appropriate resource for a nurse to consult for information on medication compatibility. Pharmacists have specialized knowledge and access to resources that provide information on drug interactions, including those between ampicillin and gentamicin sulfate. They can provide accurate and up-to-date information on whether these two medications can be safely administered together.
Choice B rationale
While the health care provider prescribes the medication, they may not have the most current or detailed information on drug compatibility. It is the pharmacist’s role to have this specialized knowledge.
Choice C rationale
Medication sales representatives are primarily focused on promoting their company’s products. They may not have comprehensive knowledge of drug interactions, especially between drugs from different companies.
Choice D rationale
The nurse manager oversees the nursing staff and coordinates care, but they may not have specific knowledge about all drug interactions. The hospital pharmacist is the most appropriate resource for this information.
Correct Answer is A
Explanation
Step 1 is… The provider has prescribed 50 mg of quetiapine to be taken orally every 12 hours. This means that each dose should be 50 mg / 2 = 25 mg.
Step 2 is… The available medication is quetiapine 25 mg tablets. Therefore, the nurse should administer 1 tablet per dose.
