Test Bank Pharmacology and the Nursing Process

Correct Answer: D

Rationale: The correct answer is D: Dopar. Dopar is a drug that increases dopamine levels by converting into dopamine in the brain. This directly restores dopaminergic activities. Artane (A) is an anticholinergic used for Parkinson's symptoms, Elavil (B) is a tricyclic antidepressant, and Benadryl (C) is an antihistamine, none of which directly target dopaminergic activities like Dopar does.

Correct Answer: C

Rationale: The correct nursing diagnosis is C: Impaired skin integrity. This choice is correct because it directly addresses the bacterial infection in the left lower leg by focusing on the skin's condition. The patient's skin integrity is compromised due to the infection, making this nursing diagnosis appropriate. Choice A (Infection) is too broad and does not specify the impact on the skin. Choice B (Risk for infection) is incorrect because the patient already has a bacterial infection, so the risk has already manifested. Choice D (Staphylococcal leg infection) is too specific and does not address the broader issue of skin integrity. Therefore, the best choice is C as it accurately reflects the patient's current condition and guides appropriate nursing interventions to address the impaired skin integrity caused by the bacterial infection.

Correct Answer: D

Rationale: The correct answer is D. Taking piroxicam with food or an oral antacid can help reduce GI irritation as it can protect the stomach lining. Piroxicam is known to cause GI upset due to its effects on prostaglandin synthesis. Spacing the administration every 4 hours (choice A) may not necessarily prevent GI upset. Using the drug for a short time only (choice B) may not address the immediate concern of GI irritation. Decreasing the piroxicam dosage (choice C) may not be necessary if taking it with food or an antacid can effectively alleviate the GI upset.

Correct Answer: A

Rationale: The correct answer is A: It inhibits deoxyribonucleic acid (DNA) synthesis. Mitomycin is an alkylating agent that works by cross-linking DNA, preventing DNA synthesis and leading to cell death. This mechanism of action makes it effective against rapidly dividing cells like cancer cells. Choice B, inhibiting ribonucleic acid (RNA) synthesis, is incorrect as mitomycin primarily targets DNA synthesis. Choice C, being cell cycle-phase specific, is incorrect as mitomycin affects cells in all phases of the cell cycle. Choice D, inhibiting protein synthesis, is incorrect because mitomycin's primary mode of action is on DNA replication, not protein synthesis.

Correct Answer: B

Rationale: The correct answer is B: It minimizes the risk of circulatory overload. When a venous access device dislodges during a transfusion, there is a risk of the infusion going into the surrounding tissues instead of the vein, leading to circulatory overload. This can result in fluid overload and potentially lead to serious complications such as heart failure. Monitoring the device ensures that the medication is delivered safely and effectively into the bloodstream. Choices A, C, and D are incorrect: A: Monitoring the device does not directly minimize the risk of phlebitis, which is inflammation of the vein. C: Monitoring the device does not directly minimize the risk of pulmonary complications, which are not typically associated with a dislodged venous access device. D: Monitoring the device does not directly minimize the risk of localized edema embolism, which is a blockage caused by a blood clot, air bubble, or other material in a blood vessel.
