Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: An open chest wound, also known as a sucking chest wound, can lead to a collapsed lung and respiratory distress. Immediate management involves sealing the wound to prevent air from entering the pleural space and further compromising the patient's respiratory function. Applying a sterile dressing over the wound helps to prevent contamination and occluding the wound with an airtight covering, such as an occlusive dressing, can effectively reduce the risk of a tension pneumothorax, a serious complication that can arise from a sucking chest wound. These interventions help to stabilize the patient's condition and improve the chances of a successful recovery. Administering supplemental oxygen, though beneficial, would be secondary to the primary management of sealing the chest wound. Providing emotional support is important but addressing the physical emergency takes precedence. Elevating the patient's legs would not be appropriate in managing an open chest wound.

Correct Answer: B

Rationale: The nurse's best response in this situation is to listen actively to the patient's concerns, acknowledge the inconvenience they are experiencing, and offer support. It is essential to validate the patient's feelings and show empathy towards their frustration. By actively listening and addressing the patient's concerns, the nurse can help alleviate some of their frustration and build a positive rapport with the patient. This approach demonstrates respect for the patient's feelings and promotes effective communication in the healthcare setting. Dismissing or ignoring the patient's frustration can lead to further dissatisfaction and impact the quality of care provided.

Correct Answer: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.

Correct Answer: C

Rationale: The nurse should prioritize removing the old dressing and applying a new dressing using sterile technique to minimize the risk of infection during a central venous catheter (CVC) dressing change. This is because the most critical step in preventing infection is maintaining a clean and sterile environment around the CVC insertion site. By using sterile technique, the nurse can reduce the introduction of microorganisms that could potentially lead to infection. Wearing sterile gloves and cleaning the insertion site with an alcohol-based antiseptic solution are important steps as well, but the key priority lies in applying the new dressing using sterile technique to prevent contamination and reduce the risk of infection.

Correct Answer: A

Rationale: Osteoporosis is a common complication associated with long-term use of corticosteroids in orthopedic patients. Corticosteroids can lead to bone loss by inhibiting bone formation and promoting bone resorption, resulting in decreased bone mineral density and increased risk of fractures. Therefore, patients on long-term corticosteroid therapy, especially in high doses, should be monitored closely for osteoporosis and receive appropriate preventive measures such as calcium, vitamin D supplementation, and bisphosphonates to mitigate the risk of bone thinning and fractures.
