Correct Answer: A

Rationale: The correct answer is A: Swelling in the limb. Swelling, particularly in one limb, is a common sign of deep vein thrombosis (DVT) and should be assessed. This swelling is often accompanied by pain, redness, and warmth in the affected area. Choices B, C, and D are incorrect because decreased heart rate, increased appetite, and improved mobility are not typically associated with DVT. The main focus in assessing for DVT is recognizing the signs and symptoms related to venous thrombosis.

Correct Answer: C

Rationale: The correct answer is C: 'Monitor for liver function.' Duloxetine is an antidepressant medication, not an antipsychotic, so choice A is incorrect. One of the common side effects of duloxetine is weight gain, making choice B incorrect. Choice D, stating that duloxetine has no side effects, is inaccurate as all medications have the potential for side effects. Monitoring liver function is crucial with duloxetine because it can impact liver function, emphasizing the importance of regular checks to ensure the client's safety.

Correct Answer: A

Rationale: In heart failure, the accumulation of fluid can lead to peripheral edema, which is swelling in the extremities. This is a common sign that healthcare professionals should monitor for. While tachycardia (increased heart rate), bradycardia (decreased heart rate), and hypotension (low blood pressure) can also occur in heart failure, they are not the primary signs typically associated with this condition. Therefore, peripheral edema is the most relevant sign to monitor in this case.

Correct Answer: B

Rationale: The correct answer is B: Teach students about healthy food choices. Teaching healthy habits like proper nutrition is an example of primary prevention because it aims to prevent disease before it occurs. Choice A, monitoring for signs of illness, is more related to secondary prevention (early detection and treatment). Choice C, administering medication to students with chronic conditions, is a form of tertiary prevention (managing existing conditions to prevent complications). Choice D, monitoring immunization compliance, is also a form of primary prevention but focuses on preventing specific infectious diseases through immunization rather than general health promotion.

Correct Answer: B

Rationale: The correct answer is B: Client is allergic to eggs. The influenza vaccine is contraindicated in individuals with an allergy to eggs because some influenza vaccines are produced using egg-based processes. Choices A, C, and D are not contraindications for administering the influenza vaccine. A low-grade fever, recent surgery, and corticosteroid therapy are not contraindications for receiving the influenza vaccine.
