A patient with a history of heart failure presents with dependent edema in the lower extremities. Which nursing action is most appropriate for managing the patient's edema?

Correct Answer: C

Rationale: The most appropriate nursing action for managing a patient with dependent edema in the lower extremities is to administer diuretics as prescribed. Diuretics help the body remove excess fluid, reducing swelling and edema in the extremities. It is important to follow the healthcare provider's orders for administering diuretics to ensure the patient's fluid balance is managed effectively. While elevating the legs above heart level and applying compression stockings may provide temporary relief, addressing the underlying cause of fluid retention with diuretics is essential for long-term management of the edema in a patient with heart failure. Encouraging increased fluid intake would not be appropriate in this case, as the focus should be on reducing fluid overload rather than increasing fluid intake.

Correct Answer: C

Rationale: Maintaining patient confidentiality is a foundational principle in healthcare ethics. Nurses are obligated to keep all information about patients confidential, which means not disclosing any patient-related information to unauthorized individuals. This includes refraining from discussing patient cases with others who are not directly involved in the care of the patient. Sharing patient information without consent can be a breach of trust and privacy, which can have legal and ethical implications. Therefore, in order to uphold the principle of confidentiality, nurses must keep all matters about the patient as a secret.

Correct Answer: A

Rationale: The response indicating Annie's present condition would be option A. This is because the symptoms mentioned in option A, such as experiencing vertigo, nausea, and nystagmus when sitting, point towards a vestibular disorder. These are symptoms commonly associated with conditions like Meniere's disease or vestibular neuritis, which can cause balance issues and feelings of dizziness. These symptoms are more indicative of Annie's current health status compared to the other options which focus on past or unrelated issues, such as ear pain during travel or impaired hearing since birth. The information provided in option A gives a more direct insight into Annie's present condition, making it the most appropriate response.

Correct Answer: C

Rationale: Feedback is an essential indicator of effective communication because it allows the sender to understand how the message was received by the receiver. It provides an opportunity to clarify any misunderstandings, confirm understanding, and ensure that the communication has been successful. Without feedback, the sender cannot be sure if their message was accurately understood or if further explanation or clarification is needed. Effective communication involves a two-way exchange, and feedback plays a crucial role in ensuring that the message is effectively transmitted and received.

Correct Answer: A

Rationale: The presentation described in the question is most consistent with anterior uveitis. Anterior uveitis, also known as iritis, is characterized by redness, pain, and photophobia in the affected eye. Slit-lamp examination typically reveals ciliary injection (reddening of the conjunctiva and episclera), corneal edema, and a mid-dilated pupil with a fixed reaction to light (miosis). This occurs due to inflammation within the anterior chamber of the eye involving the iris and ciliary body.

Correct Answer: D

Rationale: The bio-ethical principle of veracity pertains to honesty and truthfulness in healthcare communication. By providing fraudulent information about the patient's diagnosis and prognosis, the nurse would be violating the principle of veracity. It is crucial for healthcare providers to be honest and provide accurate information to patients in order to ensure informed decision-making and uphold the trust between healthcare professionals and their patients. Misleading a patient about their diagnosis and prognosis can have serious consequences on the patient's understanding of their condition, treatment decisions, and overall well-being. Therefore, maintaining honesty and truthfulness is essential in promoting ethical healthcare practices.

Correct Answer: C

Rationale: A dental abscess is characterized by a localized collection of pus that results from a bacterial infection of the tooth pulp, leading to swelling, pain, and inflammation. The infection typically occurs when bacteria enter the tooth through a cavity, crack, or other dental injury. The abscess can cause significant pain and discomfort and must be treated promptly by a dentist to prevent further complications. Dental caries refer to tooth decay or cavities that result from the breakdown of tooth structure by acids produced by bacteria. Periodontitis is a severe gum infection that damages the soft tissue and destroys the bone that supports the teeth. Oral candidiasis is a fungal infection that affects the mouth and throat.

Correct Answer: C

Rationale: Acute appendicitis is the most likely cause of the symptoms described in the pregnant woman. The classic presentation of acute appendicitis includes fever, chills, abdominal pain localized to the right lower quadrant, rebound tenderness, and guarding. Pregnant women are at a slightly higher risk of developing appendicitis due to anatomic changes and increased abdominal pressure during pregnancy, which can lead to an atypical presentation of symptoms. Prompt diagnosis and surgical intervention are crucial to prevent complications such as perforation, which can be detrimental for both the mother and the fetus.

Correct Answer: C

Rationale: Intracerebral hemorrhage is characterized by bleeding directly into the brain parenchyma, leading to the sudden onset of severe headache, vomiting, altered mental status, and neurological deficits. The hyperdense lesion seen on imaging is caused by the presence of blood within the brain tissue. This condition is often associated with hypertension and can be life-threatening if not promptly diagnosed and managed. Subdural hematoma is an accumulation of blood between the brain and its outermost covering (dura mater), typically presenting with a slower onset of symptoms compared to intracerebral hemorrhage. Subarachnoid hemorrhage involves bleeding into the space between the arachnoid membrane and the pia mater (subarachnoid space), commonly caused by the rupture of an aneurysm. Ischemic stroke results from the blockage of a blood vessel supplying the brain, leading to a lack of oxygen and nutrients to
