Correct Answer: B

Rationale: Bulimia nervosa is best defined as a pathological disorder involving recurrent episodes of binge eating followed by inappropriate compensatory behaviors to prevent weight gain, such as self-induced vomiting, excessive exercise, or misuse of laxatives. It is categorized as an eating disorder rather than a phobic disorder as it involves behaviors related to food consumption and body image, not just fears or phobias. Bulimia is not solely associated with starving oneself, as individuals with bulimia tend to consume large amounts of food during binge episodes. Therefore, the most accurate definition of bulimia is a pathological disorder of binging and vomiting.

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: D

Rationale: Respect for persons is an ethical principle that emphasizes the autonomy and freedom of individuals to make their own decisions regarding participation in research studies. In the context of human subjects research, this principle requires that individuals have the right to choose whether or not to participate in a study, without any coercion or manipulation. The principle of respect for persons also includes the concept of informed consent, where individuals must be provided with all necessary information about the study in order to make an informed decision about participation. Overall, respecting the autonomy and choices of individuals is a fundamental aspect of ethical research conduct.

Correct Answer: A

Rationale: For a patient diagnosed with a hemorrhagic stroke, the caregiver should ensure that the bed is positioned in a High-Fowler's position. This position involves elevating the head of the bed between 60 to 90 degrees. Elevating the head of the bed helps to reduce intracranial pressure and promote optimal cerebral perfusion. It also assists in maintaining proper ventilation and oxygenation, which are essential for the patient's recovery. It is important to avoid positioning the patient flat or in a prone position as these may exacerbate the condition and lead to further complications.

Correct Answer: A

Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.
