Health And Safety for Clients Questions
Question 1 of 5
The Health Information Portability and Privacy Act (HIPAA) influences nursing research primarily in the area related to:
Correct Answer: B
Rationale: The correct answer is B: protection of client. HIPAA primarily influences nursing research by ensuring the protection of patients' privacy and confidentiality. Researchers must comply with HIPAA regulations to safeguard patients' health information. This is crucial in maintaining trust and confidentiality in research. A: the cost of the study - HIPAA does not directly impact the cost of the study. C: what type of research method can be used - HIPAA does not dictate specific research methods. D: where the study may be published - HIPAA does not control where the study may be published.
Question 2 of 5
The nurse suspects the client may be developing ARDS. Which assessment data confirm the diagnosis of ARDS?
Correct Answer: A
Rationale: The correct answer is A because in ARDS, the lungs are unable to oxygenate the blood effectively despite high levels of supplemental oxygen. This results in low arterial oxygen levels even when giving a high concentration of oxygen. Choice B is incorrect because dyspnea, tachycardia, and anxiety are common symptoms of ARDS but do not confirm the diagnosis. Choice C is incorrect because clear breath sounds and a pulse oximeter reading of 95% do not confirm ARDS, as ARDS is characterized by severe oxygenation impairment. Choice D is incorrect because jugular vein distention and frothy sputum are not specific indicators of ARDS, although they may be present in some cases.
Question 3 of 5
Which physiologic mechanism of hypoxemia occurs with pulmonary fibrosis?
Correct Answer: B
Rationale: In pulmonary fibrosis, the thickened alveolar walls impair gas exchange, leading to diffusion limitation. This restricts oxygen transfer across the alveolar-capillary membrane, causing hypoxemia. Anatomic shunt (A) involves blood bypassing ventilated lung areas, not seen in pulmonary fibrosis. Intrapulmonary shunt (C) refers to blood flow through unventilated lung regions, not a characteristic of pulmonary fibrosis. V/Q mismatch ratio of less than 1 (D) indicates a ventilation-perfusion mismatch, not typically associated with pulmonary fibrosis.
Question 4 of 5
The nurse notes a patient with ARDS has a rising central venous pressure (CVP) and increasing oxygen requirements. What is the priority action?
Correct Answer: B
Rationale: The correct answer is B: Assess for fluid overload and manage diuresis if indicated. In ARDS, increasing CVP and oxygen requirements may indicate fluid overload contributing to the respiratory distress. Diuresis can help reduce fluid volume, improve oxygenation, and decrease the workload on the heart. Increasing oxygen flow rate (A) may help temporarily but doesn't address the underlying issue of fluid overload. Notifying the physician about worsening hypoxemia (C) is important but addressing fluid overload is the immediate priority. Immediate intubation (D) may be necessary in severe cases, but addressing fluid overload should be attempted first.
Question 5 of 5
Which action should the nurse take first when a patient with ARDS develops a high-pressure alarm on the ventilator?
Correct Answer: A
Rationale: The correct action is to check for kinks or obstructions in the ventilator tubing first because a high-pressure alarm indicates a potential issue with airflow, which can lead to decreased oxygenation and ventilation. By ensuring the tubing is clear, the nurse can address the immediate problem and potentially prevent further complications. Auscultating lung sounds for a pneumothorax can be important but is not the priority in this situation. Suctioning the endotracheal tube for secretions may help in some cases but should not be the first action when a high-pressure alarm occurs. Notifying the respiratory therapist is important, but resolving the potential obstruction in the ventilator tubing should be the initial step to ensure the patient's safety and optimal ventilation.
