1. Why is a beta-blocker prescribed to a client with a history of myocardial infarction?

• A. To reduce myocardial oxygen demand.
• B. To increase cardiac output.
• C. To prevent arrhythmias.
• D. To prevent the development of angina.

Correct answer: A

Rationale: The primary reason for administering a beta-blocker to a client with a history of myocardial infarction is to reduce myocardial oxygen demand. By reducing myocardial oxygen demand, beta-blockers help decrease the workload on the heart, making it easier for the heart to function effectively. This is crucial for clients with a history of myocardial infarction to prevent further damage to the heart. Choice B is incorrect because beta-blockers do not aim to increase cardiac output; instead, they help improve cardiac function by reducing workload. Choice C is incorrect because while beta-blockers can help prevent certain arrhythmias, the primary reason for their use in this case is to reduce myocardial oxygen demand. Choice D is incorrect as preventing angina is not the primary purpose of administering beta-blockers to a client with a history of myocardial infarction.

2. What is a common trigger for acute bronchospasm in asthma?

• A. Infection
• B. Allergic reaction
• C. Excessive exercise
• D. High altitude

Correct answer: B

Rationale: An allergic reaction is a common trigger for acute bronchospasm in asthma patients. When individuals with asthma come in contact with allergens like pollen, dust mites, or pet dander, it can lead to an allergic reaction that triggers bronchospasm. Infections, excessive exercise, and high altitudes can exacerbate asthma symptoms, but they are not the most common trigger for acute bronchospasm in asthma patients.

3. Which of the following is not included in the care plan of a client with moderate cognitive impairment involving dementia of the Alzheimer’s type?

• A. Daily structured schedule
• B. Positive reinforcement for performing activities of daily living
• C. Stimulating environment
• D. Use of validation techniques

Correct answer: C

Rationale: In the care plan for a client with moderate cognitive impairment involving Alzheimer's type dementia, a stimulating environment is not included as it can potentially increase confusion. Therefore, it is important to provide a familiar, structured, and predictable environment to reduce stress and disorientation. Daily structured schedules help in maintaining routine and familiarity, positive reinforcement encourages engagement in activities, and validation techniques help in communicating effectively with the client by acknowledging their feelings and reality orientation.

4. A male patient receiving androgen therapy is concerned about the risk of prostate cancer. What should the nurse explain regarding this risk?

• A. Finasteride has been shown to lower the risk of developing prostate cancer.
• B. Finasteride does not affect the risk of prostate cancer.
• C. Finasteride may increase the risk of developing prostate cancer, so regular screenings are recommended.
• D. Finasteride has no effect on the risk of prostate cancer, so regular screenings are unnecessary.

Correct answer: A

Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. However, regular screenings are still recommended to monitor for any potential issues. Choice B is incorrect because finasteride has been associated with a reduced risk of developing prostate cancer. Choice C is incorrect as finasteride is not known to increase the risk of prostate cancer; in fact, it has shown a protective effect. Choice D is incorrect because while finasteride may lower the risk of prostate cancer, regular screenings are still necessary to ensure early detection and treatment if needed.

5. The nurse is preparing to administer a vaccine to a newborn. Before administering the vaccine, the nurse should

• A. warm the vaccine to room temperature.
• B. gently cleanse the chosen injection site.
• C. check the infant's temperature.
• D. administer the full dose at a single injection site.

Correct answer: C

Rationale: Before administering a vaccine to a newborn, it is essential for the nurse to check the infant's temperature. This is important to ensure that the newborn does not have a fever, which could indicate an underlying infection or illness. Warming the vaccine to room temperature is not necessary and could be harmful. Vigorously massaging the injection site is not recommended as it can cause discomfort and tissue damage. Dividing the dose for administration to three injection sites is not standard practice for vaccine administration to a newborn.
