Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A because nosocomial pneumonia occurs in a healthcare setting, such as hospitals or long-term care facilities, where patients are at increased risk due to exposure to pathogens and weakened immune systems. Choice B is incorrect as the timeframe of onset is not limited to within 48 hours of admission. Choice C is incorrect as nosocomial pneumonia can occur in both immunocompromised and immunocompetent hosts. Choice D is incorrect as it refers to pneumonia acquired outside of a healthcare setting.

Correct Answer: D

Rationale: The correct answer is D: Tensilon test. The Tensilon test involves administering edrophonium (Tensilon) to temporarily improve muscle weakness in myasthenia gravis patients, confirming the diagnosis. Other choices are incorrect: A (Mestinon test) is not a standard diagnostic test for myasthenia gravis, B (Pulmonary function studies) are not specific for myasthenia gravis, and C (Quinine tolerance test) is not a relevant test for this condition.

Correct Answer: A

Rationale: The correct answer is A because compromised nutrition can lead to deficiencies in essential nutrients required for the production of blood cells and hemoglobin. Iron, vitamins, and minerals obtained from food are crucial for erythropoiesis and maintaining a healthy immune system. Without these nutrients, the body may struggle to produce an adequate amount of healthy red blood cells, leading to anemia and compromised immune function. Choice B is incorrect because excessive fat in the diet is not directly linked to interfering with the production of blood cells and hemoglobin. Choice C is incorrect as inconsistent dieting may affect overall health but is not specifically related to hematopoiesis. Choice D is incorrect because while iron and protein are important for blood cell production, excessive amounts of these elements are unlikely to interfere with the production of blood cells and hemoglobin.

Correct Answer: C

Rationale: The correct answer is C: Report sudden onset of acute pain. This is the highest priority because sudden onset of acute pain postoperatively can indicate a serious complication such as hemorrhage or infection. Prompt reporting allows for timely intervention to prevent further complications. A: Do not leave the patient unattended at any time - While important for safety, it is not the highest priority compared to addressing sudden onset of acute pain. B: Teach the patient not to bend over - Important for preventing complications postoperatively, but not as urgent as addressing sudden onset of acute pain. D: Apply sandbags to either side of the head - This intervention is not typically indicated for postoperative eye patients and would not address the potential serious complication of sudden onset of acute pain.

Correct Answer: B

Rationale: The correct answer is B: Ineffective airway clearance related to obstruction by a tumor or secretions. This is the highest priority because compromised airway clearance can lead to life-threatening complications such as respiratory distress or hypoxia. Ensuring effective airway clearance is crucial in preventing respiratory compromise and maintaining oxygenation. Choices A, C, and D are not the highest priority because they do not directly address the immediate risk to the client's physiological well-being. Treating disturbed body image, anxiety, or imbalanced nutrition are important but can be addressed after ensuring the client's airway is clear and they are able to breathe effectively.
