Adult Health Nursing Answer Key

Correct Answer: B

Rationale: In a patient with acute respiratory failure and hypercapnia due to a COPD exacerbation, the most appropriate intervention is the initiation of non-invasive positive pressure ventilation (NIPPV). NIPPV helps improve ventilation and oxygenation by providing mechanical support to the patient's breathing without the need for endotracheal intubation. It can reduce the work of breathing, decrease carbon dioxide retention, and improve respiratory muscle function. This intervention is particularly beneficial for COPD exacerbations as it can help alleviate hypercapnia and hypoxemia, leading to improved outcomes and potentially reducing the need for invasive ventilation methods. Therefore, NIPPV is the recommended management strategy in this scenario.

Correct Answer: D

Rationale: Informed consent is a critical ethical requirement in research involving human participants. In this study scenario, it is crucial that both the participants and their parents provide consent. The involvement of the parents is important, especially when the participants are minors or vulnerable individuals who may not fully understand the study's implications or risks. By obtaining consent from both the participants and their parents, researchers can ensure that everyone involved is aware of what participation in the study entails, including any potential risks or benefits. This approach upholds the principles of autonomy, respect for individuals, and ethical research conduct.

Correct Answer: A

Rationale: The patient's presentation with a blood sugar level of 800mg/dL, absence of ketones in the urine, dehydration, and altered mental status points towards Hyperosmolar nonketotic coma (HNKC). HNKC typically occurs in patients with Type 2 diabetes and is characterized by extremely high blood glucose levels (hyperglycemia) without significant ketosis. The absence of ketones in the urine distinguishes HNKC from Diabetic ketoacidosis (DKA). Patients with HNKC often present with severe dehydration, altered mental status, and hyperosmolarity. It is crucial to address the underlying cause of the hyperglycemia, correct dehydration, and normalize blood glucose levels promptly in the management of HNKC.

Correct Answer: A

Rationale: The recommended position for a conscious patient experiencing an acute asthma exacerbation is the High-Fowler's position. This position involves the patient sitting upright or almost upright at about a 90-degree angle. The High-Fowler's position helps improve ventilation by expanding the lungs and maximizing airflow in and out of the airways. It also reduces the work of breathing in patients with asthma by allowing gravity to assist in moving air in and out of the lungs more easily. Additionally, this position can help alleviate shortness of breath and improve oxygenation in patients experiencing an asthma exacerbation.

Correct Answer: C

Rationale: Deductive reasoning is a logical process in which conclusions are drawn from a set of premises or given information. In quantitative research, this type of reasoning is commonly used to test hypotheses and make predictions based on theories and existing knowledge. Researchers start with established theories or hypotheses and then collect data to either support or refute them. This structured approach aligns with the principles of deductive reasoning and is a key characteristic of quantitative research methodology.
