Test Bank Pharmacology and the Nursing Process

Correct Answer: A

Rationale: The correct answer is A because it demonstrates data validation in making a nursing clinical decision. The nurse assesses the time of the last dressing change and compares it with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and validated data, leading to appropriate patient care. Choice B is incorrect because it does not involve data validation. The decision is driven by increased pain and family requests, without verifying the underlying cause. Choice C is incorrect as it involves responding to a patient's reported symptom (leg cramps), but it does not involve data validation in making the clinical decision. Choice D is incorrect as it relies solely on the patient's report of decreased mobility without further data validation.

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: A

Rationale: The correct answer is A because it demonstrates data validation in nursing clinical decision-making. In this scenario, the nurse considers the patient's self-reported information (time of last dressing change and observation of old and new drainage) as key data points to validate the need for changing the wound dressing. This aligns with the principles of evidence-based practice and ensures that the decision is based on accurate and relevant information. Choices B, C, and D are incorrect because they do not involve the systematic validation of data to inform the nursing decision-making process. Choice B relies on family input rather than objective data, Choice C jumps to a treatment decision without confirming the underlying cause, and Choice D does not involve validating the patient's reported symptom before taking action.

Correct Answer: C

Rationale: The correct answer is C: An intravenous set-up. Checking for an intravenous set-up is crucial to ensure that Mrs. Zeno is receiving necessary medications or fluids. It allows the nurse to monitor the infusion rate, prevent potential complications like infiltration, and ensure proper medication administration. A tracheostomy set (A) may be important for respiratory support but not essential for immediate safety. A hypothermia blanket (B) is used for temperature management and not directly related to Mrs. Zeno's immediate safety. A syringe and edrophonium HCl (D) are specific to a diagnostic test for myasthenia gravis and not necessary for general bedside safety assessment.

Correct Answer: B

Rationale: The correct answer is B: The potential complication. In a collaborative problem, the focus of a diagnostic statement should be on identifying any potential complications that may arise due to the client's condition or treatment. This allows nurses and other healthcare professionals to anticipate and address these complications proactively. A: The client problem - While important, the client problem is usually addressed in the nursing diagnosis rather than the diagnostic statement for a collaborative problem. C: The nursing diagnosis - The nursing diagnosis focuses on the actual or potential health problems that the client is experiencing, which is different from the focus of a diagnostic statement for a collaborative problem. D: The medical diagnosis - The medical diagnosis is the identification of a disease or condition by a healthcare provider, which is not the focus when identifying potential complications in a collaborative problem.
