Question 1 of 5
Fundamental action of vaccines :
Correct Answer: C
Rationale: The fundamental action of vaccines is prophylaxis, which means the prevention of disease. Vaccines are designed to stimulate the body's immune system to recognize and fight specific pathogens before they cause infection or illness. By introducing a weakened or inactivated form of the pathogen to the body, vaccines trigger an immune response and teach the immune system how to recognize and destroy the pathogen in the future. Through prophylaxis, vaccines help protect individuals from getting sick with certain diseases.
Question 2 of 5
A patient is taking aspirin for secondary prevention of myocardial infarction and is experiencing moderate gastrointestinal upset. The nurse will contact the patient™s provider to discuss changing from aspirin to which of the following?
Correct Answer: D
Rationale: Coated aspirin refers to enteric-coated aspirin, which is a type of aspirin that has a special coating designed to help protect the stomach lining and reduce gastrointestinal upset. Unlike regular aspirin, enteric-coated aspirin is less likely to cause irritation to the stomach and therefore may be a better option for patients experiencing gastrointestinal issues. Switching to coated aspirin can help alleviate the patient's symptoms while still providing the antiplatelet benefits needed for secondary prevention of myocardial infarction. It is important for the nurse to communicate with the provider to discuss this alternative option and ensure the patient's safety and well-being.
Question 3 of 5
Which instruction is important for the nurse to include when teaching a patient about imatinib therapy?
Correct Answer: A
Rationale: Grapefruit juice can inhibit the metabolism of imatinib, leading to increased drug levels and a higher risk of side effects. Patients should be advised to avoid grapefruit juice while on imatinib therapy. Headaches are not typically an emergency unless severe or accompanied by other symptoms. Imatinib is a long-term treatment, not one that stops working after 2 months. Taking the drug on an empty stomach is not required; it can be taken with food to reduce gastrointestinal side effects.
Question 4 of 5
Which drug is most useful to prevent and treat cerumen impaction?
Correct Answer: A
Rationale: Hydrogen peroxide is commonly used to soften and remove cerumen (earwax) impaction due to its effervescent properties, which help break down the wax. Rubbing alcohol (B) is used for drying the ear canal but is not effective for cerumen impaction. Charcoal (C) and clove oil (D) are not used for this purpose.
Question 5 of 5
A patient has a new prescription for a blood pressure medication that may cause him to feel dizzy during the first few days of therapy. Which is the best nursing diagnosis for this situation?
Correct Answer: B
Rationale: Dizziness is a common side effect of many blood pressure medications, particularly during the initial days of therapy. This side effect increases the patient's risk of falls or other injuries, especially in elderly patients or those with mobility issues. The nursing diagnosis 'Risk for injury' is the most appropriate because it directly addresses the potential harm caused by dizziness. While 'Activity intolerance' and 'Self-care deficit' may be relevant in some cases, they do not specifically address the immediate risk posed by dizziness. 'Disturbed body image' is unrelated to this scenario. Therefore, 'Risk for injury' is the best diagnosis to guide nursing interventions, such as monitoring the patient and educating them on safety measures.
