Correct Answer: B

Rationale: The healthcare professional should withhold the medication and notify the provider of the client's previous reaction to penicillin. This information is crucial for the provider to prescribe an alternative antibiotic. Allergic reactions to penicillin can range from mild to severe anaphylaxis, so prior sensitization should be reported to the provider to avoid potential adverse reactions.

Correct Answer: C

Rationale: The correct instruction for the nurse to include is to advise the client to take Levodopa/Carbidopa with food. This recommendation helps reduce gastrointestinal side effects commonly associated with this medication. Food can help minimize nausea and other stomach-related issues that may occur when taking Levodopa/Carbidopa.

Correct Answer: A

Rationale: To calculate the volume to administer, use the formula: (Desired dose / Concentration) = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL, which is rounded up to 0.8 mL. Therefore, the healthcare professional should administer 0.8 mL per dose of heparin.

Correct Answer: C

Rationale: Sucralfate can interfere with the absorption of phenytoin. To prevent this interaction, the client should allow a 2-hour interval between taking sucralfate and phenytoin. This timing helps to ensure adequate absorption and effectiveness of both medications without compromising therapeutic outcomes.

Correct Answer: C

Rationale: The correct answer is increased urine output. Dopamine increases cardiac output and improves renal perfusion, leading to increased urine output. This response indicates that the medication is effective in treating shock by enhancing renal function and perfusion.
