In the ethical principle of beneficence, which is the BASIS of every nursing action in all work settings?

Correct Answer: D

Rationale: The ethical principle of beneficence, which is the basis of every nursing action in all work settings, emphasizes the importance of doing good at all times for the benefit of the patient. Nurses are expected to act in the best interest of their patients and strive to promote their well-being and welfare. This principle guides nurses to provide care that is compassionate, effective, and in line with the patient's needs and preferences. By prioritizing the good of the patient in all actions and decisions, nurses uphold the principle of beneficence and demonstrate their commitment to promoting positive outcomes for those under their care.

Correct Answer: C

Rationale: Medico-legal charts are typically stored for a minimum of 10 years after the case is closed to ensure compliance with legal requirements and to provide a comprehensive record of the medical care provided. This duration allows for potential future reference, follow-up treatment, or legal purposes that may arise within the specified timeframe. It is important to maintain these records for an extended period to protect both the patient's rights and the healthcare provider's accountability. Additionally, storing medico-legal charts for 10 years aligns with standard retention practices in the healthcare industry.

Correct Answer: D

Rationale: Tipping Claudia's head back slightly helps in reaching the conjunctival sac easily. The conjunctival sac is a small space between the lower eyelid and the eye itself where eye drops are typically administered. Tilting the head back allows for better access to this area, ensuring the eye drops are delivered accurately and effectively into the eye.

Correct Answer: D

Rationale: The causative agent of dengue fever is a virus. Dengue fever is primarily transmitted to humans by the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. These mosquitoes act as vectors, carrying and transmitting the dengue virus (specifically four closely related but antigenically different serotypes: DEN-1, DEN-2, DEN-3, and DEN-4) to humans during the feeding process. The virus then replicates in the human body, causing symptoms of dengue fever. Therefore, the correct answer is D. Virus.

Correct Answer: C

Rationale: Using an expired skin preparation solution can compromise the safety and effectiveness of the surgical site cleansing. Expired solutions may have reduced efficacy or could cause adverse reactions due to chemical breakdown over time. Therefore, it is essential for the nurse to discard the expired solution and obtain a new one to ensure proper sanitation and reduce the risk of complications during the surgical procedure. It is important to adhere to proper protocols and guidelines in healthcare settings to maintain patient safety and optimal outcomes.

Correct Answer: A

Rationale: The most significant contributory factor to the development of lung cancer is being a cigarette smoker. Cigarette smoking is directly linked to approximately 85% of lung cancer cases. The harmful substances in tobacco smoke, such as carcinogens, damage the cells in the lungs, leading to the development of cancer over time. Smokers are at a significantly higher risk of developing lung cancer compared to non-smokers. Therefore, being a cigarette smoker is the primary and most influential risk factor for developing lung cancer.

Correct Answer: D

Rationale: The prioritized nursing intervention in this situation should be assessing for the risk of harm to self or infant. It is crucial to ensure the safety of the postpartum client and her infant as depression can increase the risk of self-harm or harm to the newborn. By assessing for any potential risks, the nurse can take appropriate actions to prevent any harm and ensure the well-being of both the client and the infant. Once the assessment is completed, further interventions like encouraging participation in support groups, referring to a mental health professional, or administering medications can be considered based on the assessment findings.

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: C

Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not
