Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: C

Rationale: Carvedilol is a beta-blocker primarily used to manage heart failure and hypertension. Monitoring blood pressure closely during carvedilol therapy is crucial because it helps assess the drug's effectiveness in managing heart failure and controlling hypertension. Carvedilol works by blocking certain receptors in the heart and blood vessels, which can lower blood pressure. Monitoring blood pressure fluctuations allows healthcare providers to adjust the dosage accordingly to achieve optimal results and prevent potential complications in patients with heart failure. While monitoring blood glucose levels, serum potassium levels, and liver function tests are essential in managing other conditions or medications, the priority in a patient being prescribed carvedilol for heart failure is to monitor blood pressure levels.

Correct Answer: A

Rationale: Participating in professional organizations can provide Nurse Bea with numerous opportunities to network with other professionals in the field, stay updated with the latest trends and developments in nursing, access resources for professional growth, and even participate in leadership roles within the organization. Being active in a professional organization can help Nurse Bea build her professional profile, gain recognition, and open up possibilities for career advancement and opportunities for collaboration and learning from peers. It can also help her stay connected with the broader nursing community and enhance her visibility within the field. Engaging with a professional organization is a valuable way for Nurse Bea to enhance her career alongside pursuing further education.

Correct Answer: A

Rationale: Administering intravenous fluids as ordered is the most appropriate nursing action for a postpartum client exhibiting signs of severe dehydration. Severe dehydration, as indicated by dry mucous membranes, decreased skin turgor, and oliguria, requires immediate intervention to restore fluid balance effectively. Intravenous fluids deliver fluids directly into the bloodstream, ensuring rapid rehydration and addressing the critical situation promptly. Offering oral rehydration solutions may not be sufficient to address severe dehydration, and providing education on fluid intake can be important for prevention but is not the immediate priority in this scenario. Notifying the healthcare provider is essential, but initiating intravenous fluids promptly is crucial in managing severe dehydration.

Correct Answer: C

Rationale: Mast cells are primarily responsible for mediating allergic responses such as severe allergies. When an allergen triggers the immune response, mast cells release histamine, leukotrienes, and other inflammatory mediators. These substances cause symptoms such as difficulty breathing, hives, and swelling. Basophils also release histamine, but mast cells are more abundant in tissues and play a significant role in allergic reactions. Eosinophils are involved in allergic reactions but are more focused on combating parasitic infections. Neutrophils are not typically involved in allergic responses but play a key role in combating bacterial infections.

Correct Answer: D

Rationale: In the scenario described, the patient is experiencing severe hypoxemia refractory to conventional oxygen therapy, indicating a need for advanced respiratory support. When a patient with ARDS fails to respond to conservative management, including mechanical ventilation strategies, prone positioning, and recruitment maneuvers, the next step may involve extracorporeal membrane oxygenation (ECMO). ECMO provides a way to bypass the lungs and oxygenate the blood directly, allowing for enhanced gas exchange and support for severely compromised respiratory function. Therefore, in this critical situation, prioritizing the recommendation for ECMO can offer the patient the best chance of improving oxygenation and survival.
