Correct Answer: C

Rationale: The patient's presentation of swelling of the ankles, dyspnea on exertion, and orthopnea is highly suggestive of heart failure. The echocardiogram findings of decreased left ventricular ejection fraction and dilated left ventricle are characteristic of heart failure with reduced ejection fraction (HFrEF), also known as systolic heart failure. In this condition, the heart's ability to pump blood effectively is compromised, leading to symptoms of congestion and decreased cardiac output. The decreased ejection fraction indicates that the heart is not able to efficiently pump out blood with each contraction. Dilatation of the left ventricle is a compensatory mechanism in response to increased volume overload.

Correct Answer: B

Rationale: Nurses are bound by strict confidentiality and privacy regulations in their profession. If a nurse fails to keep a patient's personal information confidential and discloses it without authorization, they can be charged with invasion of privacy. Invasion of privacy is the wrongful intrusion into a person's private affairs without their consent, and it is a serious violation of ethical and legal standards in healthcare. Nurses must always prioritize patient confidentiality to maintain trust and uphold ethical standards in their practice.

Correct Answer: B

Rationale: When a patient describes their pain as a 5 on the pain assessment scale, it indicates severe pain and the need for a strong pain medication. Morphine Sulphate is a potent opioid analgesic that is commonly used to manage severe pain, such as in cases where the pain is rated as 5. Meperidine HCl (Demerol) is another opioid analgesic, but it is not as commonly used due to its side effect profile and potential for toxicity. Fentanyl (Duragesic) is also a potent opioid analgesic that can be used for severe pain, but morphine is often preferred in this situation. Acetaminophen (Tylenol) is a milder pain reliever and is not typically sufficient for pain described at a level of 5 on the pain scale.

Correct Answer: C

Rationale: A living will is a legal document that outlines a person's preferences and wishes regarding medical treatment, including resuscitation, in the event they become unable to communicate or make decisions. In this scenario, the client being admitted to the oncology unit wants to convey his wishes regarding resuscitation in case of cardiopulmonary arrest. A living will helps ensure that these wishes are known and respected by healthcare providers and loved ones. While a will addresses how a person's assets should be distributed after death and a health care power of attorney designates someone to make medical decisions on the person's behalf, a living will specifically focuses on healthcare preferences and treatment decisions. A proxy directive is similar to a health care power of attorney, designating someone to make healthcare decisions for the person if they are unable to do so themselves.

Correct Answer: A

Rationale: Utilizing communication and social media responsibly is an indicator that models personal and professional behavior and values. Responsible use of communication and social media demonstrates a commitment to maintaining a positive online presence, interacting respectfully with others, and upholding professional standards in digital communication. This behavior reflects integrity, accountability, and respect for oneself and others, which are essential qualities in both personal and professional settings. Additionally, demonstrating responsible behavior in the digital sphere can help build trust, enhance reputation, and foster valuable relationships with colleagues, clients, and the community.
