Pharmacology and the Nursing Process 10th Edition Test Bank

Correct Answer: D

Rationale: The correct answer is D: Observe for muscle twitching and numbness or tingling of the lips, fingers, and toes. After a thyroidectomy, the parathyroid glands may be inadvertently damaged, leading to hypocalcemia. Muscle twitching and numbness/tingling are early signs of hypocalcemia. The nurse should monitor for these symptoms to detect and address hypocalcemia promptly. Choice A is incorrect as monitoring thyroid-stimulating hormone levels is not related to hypocalcemia. Choice B is incorrect as it describes signs of potential complications like bleeding or airway obstruction, not hypocalcemia. Choice C is incorrect as changes in voice quality and gastric issues are not specific to hypocalcemia.

Correct Answer: A

Rationale: The correct answer is A: Pyridoxine. Pyridoxine can reduce the effectiveness of Levodopa by converting it into dopamine before it reaches the brain, decreasing the therapeutic effects. Bromocriptine and Amantadine are actually used in combination with Levodopa to enhance its effects by different mechanisms. Choosing Amantadine as the answer is incorrect because it is listed twice in the choices and would not interfere with Levodopa's effectiveness.

Correct Answer: B

Rationale: The correct answer is B because starting birth control pills does not protect against HIV transmission to the baby during pregnancy. The other choices demonstrate understanding of HIV transmission risks and prevention methods. A shows awareness of vertical transmission, C recognizes that not all babies born to HIV-positive mothers are infected, and D acknowledges the potential need for a C-section to reduce transmission risk. Starting birth control pills is unrelated to preventing mother-to-child HIV transmission during pregnancy.

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: B

Rationale: The correct answer is B: inadequate supply of oxygen to the myocardium. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle. This lack of oxygenated blood supply to the myocardium leads to ischemia, resulting in the characteristic chest pain. Choice A is incorrect as it refers to a decrease in alveolar surface area for gas exchange, which is related to conditions like emphysema, not angina. Choice C is incorrect as it pertains to pulmonary circulation, not coronary circulation. Choice D is incorrect as an increase in alveolar surface area would not be a cause of angina pectoris.
