Correct Answer: D

Rationale: Atorvastatin requires monitoring for liver function due to its potential to cause liver abnormalities. It can also lead to muscle pain or weakness, a condition known as myopathy. Choice C is incorrect as atorvastatin is contraindicated during pregnancy due to potential harm to the fetus, making choices A and B the correct options to include in patient education.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for chest pain and report any recurrence.' After a myocardial infarction, it is crucial for clients to be vigilant about any signs of chest pain as it could indicate a recurrent event. Prompt reporting of chest pain can lead to timely intervention, preventing further complications. Choice A is incorrect because resuming normal activities immediately after a heart attack can be dangerous and is not recommended. Choice C is also incorrect as avoiding all physical activity for 6 months is excessive and can lead to deconditioning. Choice D is incorrect as medications prescribed after a myocardial infarction are usually meant to be taken regularly as prescribed, not just as needed.

Correct Answer: D

Rationale: When a client is receiving digoxin therapy, it is crucial for the nurse to monitor liver function, serum electrolytes (especially potassium levels), and blood pressure. Digoxin is known to affect the heart's electrical activity and can lead to toxic effects if not managed properly. Monitoring liver function helps to assess the drug's metabolism and excretion. Checking serum electrolytes, especially potassium, is essential because digoxin toxicity can be exacerbated by electrolyte imbalances, particularly hypokalemia. Monitoring blood pressure is necessary because digoxin can influence cardiac contractility and heart rate, potentially affecting blood pressure. Therefore, monitoring all these parameters is vital to ensure the client's safety and therapeutic effectiveness of digoxin. Choices A, B, and C are incorrect because monitoring only one or two of these parameters may not provide a comprehensive assessment of the client's response to digoxin therapy.

Correct Answer: B

Rationale: The correct answer is B: Administer it on an empty stomach. Iron supplements are best absorbed on an empty stomach to enhance their absorption. It is important to avoid giving them with milk or dairy products as these can inhibit iron absorption. Checking blood pressure and monitoring for allergic reactions are not directly related to the administration of iron supplements and are not the primary considerations in this case.

Correct Answer: C

Rationale: The correct answer is C: Acquired immunity. Acquired immunity occurs when an individual is given a vaccine or immunization to develop antibodies. This type of immunity is specific and develops after exposure to an antigen. Innate immunity (choice A) is the body's natural defense system present at birth. Passive immunity (choice B) is temporary immunity passed from one individual to another. Natural immunity (choice D) refers to immunity that is not gained through medical intervention or deliberate exposure.
