Pharmacology and the Nursing Process 10th Edition Test Bank

Correct Answer: B

Rationale: The correct answer is B: "I will press the button whenever I feel pain." This answer demonstrates understanding of how patient-controlled analgesia (PCA) works, where the client self-administers medication when needed for pain relief. Option A is incorrect as the machine is programmed with lockout intervals to prevent overdosing. Option C is incorrect as the client should only press the button when experiencing pain, not on a fixed schedule. Option D is incorrect as PCA does not guarantee complete pain elimination. The key in PCA is empowering the client to self-administer medication based on their pain level.

Correct Answer: A

Rationale: The correct answer is A because signs and symptoms listed are indicative of disseminated intravascular coagulation (DIC), which is a serious condition where blood clotting and bleeding occur simultaneously. Change in level of consciousness can indicate hypoperfusion from clotting in blood vessels. Tachypnea and tachycardia can result from tissue hypoxia. Petechiae are small red or purple spots on the skin due to bleeding under the skin. Choices B, C, and D are incorrect because they do not align with the typical signs and symptoms of DIC. Choice B suggests a possible myocardial infarction or acute coronary syndrome. Choice C indicates a possible thrombotic thrombocytopenic purpura (TTP) or acute limb ischemia. Choice D suggests a mix of symptoms that do not typically present together in DIC.

Correct Answer: C

Rationale: The correct answer is C because washing feet in hot water can lead to burns or skin damage for those with diabetes. A: Proper footwear is essential for preventing foot injuries. B: Trimming toenails straight across helps prevent ingrown nails. D: Wearing shoes on hot surfaces prevents burns or blisters. Overall, C is incorrect due to the potential harm it can cause to diabetic feet.

Correct Answer: D

Rationale: The correct answer is D: Lymphocyte. Lymphocytes are a type of white blood cell that play a crucial role in adaptive immunity. They include T cells and B cells, which are responsible for recognizing and attacking specific pathogens. T cells help regulate the immune response and directly attack infected cells, while B cells produce antibodies to target pathogens. Neutrophils (A), monocytes (B), and basophils (C) are important for innate immunity, not adaptive immunity. Neutrophils are phagocytic cells that engulf and destroy pathogens, monocytes differentiate into macrophages to engulf pathogens, and basophils are involved in allergic reactions. Therefore, the correct answer is D because lymphocytes are key players in adaptive immunity.
