A patient is prescribed a beta blocker. Beta blockers are as effective as antianginals because they do what?

Correct Answer: C

Rationale: The correct answer is C because beta blockers decrease heart rate and myocardial contractility, which reduces myocardial oxygen demand and improves symptoms of angina. Choice A is incorrect as beta blockers do not directly increase oxygen supply. Choice B is incorrect as beta blockers actually decrease heart rate. Choice D is incorrect because beta blockers decrease, not increase, myocardial contractility to decrease workload on the heart.

Correct Answer: A

Rationale: The correct answer is A because it emphasizes the importance of avoiding certain foods while starting an MAOI medication, provides a clear timeline for the patient to follow, and offers the opportunity to address any questions. This approach ensures the patient is well-informed about dietary restrictions and can make necessary adjustments. Choice B is incorrect because it does not specify the timeline for avoiding certain foods, ordering the new medication, or addressing potential concerns the patient may have. Choice C is incorrect as it delays the prescription for the new medication until after the patient has been off Zoloft for 4 weeks, potentially leaving the patient without treatment during this period. Choice D is incorrect because it rushes the process by only allowing 2 days off Zoloft before starting the new medication, which may not provide enough time for the previous medication to clear the system and may lead to adverse interactions.

Correct Answer: B

Rationale: The correct answer is B: Chronic pain. The patient's pain has been ongoing for 4 months and is gradually increasing, indicating a long-lasting and persistent nature characteristic of chronic pain. Chronic pain is defined as pain lasting beyond the expected healing time. Acute pain (choice A) is sudden and short-term. Somatic pain (choice C) arises from the skin, muscles, or bones and is localized, not consistent with the abdominal pain described. Neuropathic pain (choice D) results from nerve damage and is typically described as burning or shooting, not matching the dull ache described by the patient.

Correct Answer: B

Rationale: The correct answer is B because chlorpromazine can cause photosensitivity, making the patient more prone to sunburn and skin damage. It is essential for the patient to wear sunscreen while outside to protect their skin. Choice A is incorrect as there is no specific interaction between chlorpromazine and caffeine. Choice C is incorrect because long-term therapy with chlorpromazine is more likely to result in sedation and drowsiness rather than nervousness and excitability. Choice D is incorrect as antacids may interfere with the absorption of chlorpromazine, so they should not be taken together.

Correct Answer: B

Rationale: The correct answer is B: Deficient knowledge. Patients receiving antidysrhythmics need education to understand the medication's purpose, side effects, and signs of complications. This empowers patients to manage their condition effectively. The other options are not directly related to the administration of antidysrhythmics. A (Risk for infection) is not typically a priority for patients receiving antidysrhythmics. C (Deficient fluid volume) may be relevant if the medication causes electrolyte imbalances, but education is more critical. D (Urinary retention) is not commonly associated with antidysrhythmics. Thus, B is the most appropriate nursing diagnosis for a patient receiving antidysrhythmics.
