Correct Answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

Correct Answer: B

Rationale: The correct answer is B: Fried chicken. High-fat foods, like fried chicken, can delay the absorption of Ramelteon. It is important for the client to avoid such foods to ensure the medication's effectiveness. Baked potato, whole-grain bread, and citrus fruits do not have a significant interaction with Ramelteon and can be consumed safely while taking the medication.

Correct Answer: C

Rationale: When Oxycodone, a narcotic analgesic, and Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), are taken together, they work synergistically to enhance the pain-relieving effects of both medications. These drugs act through different mechanisms, leading to a combined analgesic effect that is more effective than when used alone. Therefore, the interaction between Oxycodone and Ibuprofen results in an increase in the expected therapeutic effect of both medications.

Correct Answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to suppress bone marrow function, resulting in decreased production of red blood cells and subsequently causing fatigue due to anemia. Monitoring for fatigue is essential to ensure early detection and management of this adverse effect.

Correct Answer: C

Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with a history of bronchial asthma. Reporting a history of bronchial asthma to the provider is crucial as it would prompt a review of the medication prescription to avoid potential adverse effects and consider alternative treatment options.
