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 D
Explanation
If there is a delay in receiving the new TPN solution from the pharmacy, the nurse should infuse Dextrose 10% in water until the next TPN solution is available. This is because stopping TPN abruptly can cause hypoglycemia. Dextrose 10% in water can provide a source of glucose to prevent hypoglycemia.
Correct Answer is D
Explanation
Choice A rationale:
Elastic bandages can contain latex, which could potentially cause an allergic reaction. However, latex-free alternatives are available. The client should be advised to specifically look for latex-free bandages. This statement indicates a need for further teaching because using standard elastic bandages might expose the client to latex.
Choice B rationale:
Many dishwashing gloves are made from latex, but there are latex-free alternatives available. The client should be instructed to use latex-free gloves to avoid latex exposure. This statement indicates a need for further teaching as the client might choose latex gloves unintentionally.
Choice C rationale:
Most ink pens do not contain latex. Therefore, using ink pens is generally safe for individuals with latex allergies. This statement does not indicate a need for further teaching.
Choice D rationale:
Balloon latex is a common allergen, and exposure to latex balloons can trigger an allergic reaction in individuals with latex allergies. This statement indicates a need for further teaching because the client should avoid latex balloons and opt for latex-free alternatives to prevent allergic reactions.
