Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important preprocedure teaching for carotid angiography because it prepares the patient for a common sensation during the procedure, helping to manage their expectations and reduce anxiety. This information is crucial for informed consent. Choice A is incorrect because carotid angiography is usually done under local anesthesia, not general anesthesia. Choice B is incorrect as carotid angiography typically takes about 1-2 hours, not several hours. Choice D is incorrect because all medical procedures, including carotid angiography, carry potential risks and complications, which should be discussed with the patient.

Correct Answer: B

Rationale: The correct answer is B because the nurse should always prioritize communication with the patient, especially when the patient is alert and oriented. Speaking only to the patient's daughter could undermine the patient's autonomy and right to be involved in their care. It is important for the nurse to directly address the patient to gather accurate information and ensure patient-centered care. Making eye contact (A), leaning forward (C), and nodding periodically (D) are all appropriate communication techniques that show attentiveness and engagement with the patient, which are crucial in building rapport and trust.

Correct Answer: D

Rationale: The correct answer is D because assessing for localized ischemia involves evaluating multiple factors. A: Assessing color and temperature helps determine perfusion. B: Checking capillary refill assesses circulation. C: Evaluating pulse rate indicates cardiac output. Doing all of the above provides a comprehensive assessment of arterial flow and potential ischemia. Other choices are incorrect as they do not cover all aspects necessary for a thorough assessment.

Correct Answer: C

Rationale: The correct answer is C: Bronchospasm. Antiplatelet drugs commonly cause hypersensitivity reactions like bronchospasm due to their effects on platelet function. They can trigger an allergic response leading to bronchoconstriction. Difficulty hearing (A) is not a common hypersensitivity reaction to antiplatelet therapy. Confusion (B) is more commonly associated with central nervous system effects rather than hypersensitivity reactions. Agranulocytosis (D) is a severe drop in white blood cells and is not typically a hypersensitivity reaction to antiplatelet drugs.

Correct Answer: D

Rationale: The correct answer is D because antimetabolites interfere with the synthesis of nucleic acids (RNA and/or DNA), affecting multiple stages of RNA and DNA synthesis. This disruption hinders cell division and leads to cell death. Choices A and B are incorrect because antimetabolites do not specifically target cell division during the M phase or normal cellular processes during the S phase. Choice C is also incorrect because antimetabolites primarily target nucleic acid synthesis rather than altering the chemical structure of DNA or the binding between DNA molecules.
