Correct Answer: A

Rationale: Step-by-step rationale: 1. High HDL cholesterol is considered beneficial as it helps remove LDL cholesterol from arteries, reducing the risk of plaque buildup. 2. Low HDL cholesterol is associated with an increased risk of cardiovascular disease. 3. Low total cholesterol may not necessarily indicate a decreased risk, as it could be due to low levels of protective HDL cholesterol. 4. Low triglycerides, while generally considered good, do not directly indicate a decreased risk of cardiovascular disease like high HDL cholesterol does. In summary, high HDL cholesterol is the correct answer as it plays a crucial role in reducing the risk of cardiovascular disease by removing LDL cholesterol, whereas the other choices do not offer the same protective benefits.

Correct Answer: A

Rationale: The correct answer is A: Apply a sterile dressing. This is the most important intervention to prevent infection and protect the wound. Applying a sterile dressing helps maintain a clean environment, reduces the risk of contamination, and promotes wound healing. Administering fluids (B) may be necessary but is not the top priority. Administering IV antibiotics (C) may be required but is secondary to wound care. Monitoring for bleeding (D) is important but addressing the wound with a sterile dressing takes precedence to prevent infection.

Correct Answer: D

Rationale: The correct answer is D because it provides a thorough list of specific childhood illnesses and confirms the patient's denial of having had them. This approach ensures comprehensive documentation and accuracy. Choice A is vague and lacks specificity, potentially leading to misunderstandings. Choice B focuses on the patient's perception of their health rather than actual illnesses. Choice C mentions the patient's sister and measles, which is irrelevant to the patient's own medical history. Overall, choice D is the most accurate and relevant option for documenting the patient's childhood illnesses.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. In severe allergic reactions, such as anaphylaxis, epinephrine is the first-line treatment as it rapidly reverses life-threatening symptoms like airway constriction and low blood pressure. Antihistamines (choice B) may help with mild symptoms but are not sufficient for severe reactions. Applying a cold compress (choice C) is not effective in treating anaphylaxis. Encouraging deep breathing (choice D) is not appropriate as the client may have difficulty breathing due to airway constriction. Administering epinephrine is crucial to quickly stabilize the client's condition in a severe allergic reaction.

Correct Answer: B

Rationale: Correct Answer: B (Administer nonsteroidal anti-inflammatory drugs - NSAIDs) Rationale: 1. NSAIDs are commonly used for chronic pain management due to their anti-inflammatory properties. 2. NSAIDs target the underlying inflammation that often contributes to chronic pain. 3. Opioids may be reserved for severe pain due to their potential for addiction and side effects. 4. Monitoring blood pressure is important but not the primary intervention for chronic pain. 5. Acetaminophen is a mild pain reliever and may not be as effective for chronic pain compared to NSAIDs.
