Pharmacology and the Nursing Process Test Bank

Correct Answer: A

Rationale: The correct answer is A because validating the client's statement about not needing glasses is crucial for accurate data collection. This step ensures that the client's difficulty reading is not due to poor eyesight. - Choice B is about interpreting physical signs, not client data validation. - Choice C involves documenting objective findings, not validating client information. - Choice D pertains to a client's complaint, not necessarily requiring validation.

Correct Answer: D

Rationale: The correct answer is D: Kaposi�s sarcoma. This is a common AIDS-related cancer caused by Human Herpesvirus 8 (HHV-8) in immunosuppressed individuals. It presents as purplish lesions on the skin and mucous membranes. Squamous cell carcinoma (A) is not specific to AIDS. Leukemia (B) and Multiple myeloma (C) are not commonly associated with AIDS. Kaposi�s sarcoma is the hallmark cancer seen in AIDS patients due to their weakened immune system.

Correct Answer: C

Rationale: The correct answer is C: Inform the registered nurse. This is the best course of action as the LPN should escalate the situation to a higher level of care by involving the registered nurse who can further assess the patient's concerns and provide appropriate interventions. A. Reassuring the patient may not address the underlying fear and may not be sufficient to alleviate their anxiety. B. Providing statistics about surgery death rates may further escalate the patient's fears and anxiety, causing more harm than good. D. Involving the family to comfort the patient may not address the patient's specific concerns and may not be within the family's scope of understanding or expertise to effectively address the situation. Informing the registered nurse allows for a more comprehensive assessment and appropriate intervention to address the patient's fears and concerns in a holistic manner.

Correct Answer: C

Rationale: The correct answer is C: A decreased number of functioning acetyl-choline receptor sites. This is because in diseases like myasthenia gravis, there is an autoimmune attack on acetylcholine receptor sites, leading to decreased functionality. Choice A is incorrect because it refers to a genetic defect in acetylcholine production, which is not typically the cause of myasthenia gravis. Choice B is incorrect as it suggests a reduced amount of acetylcholine, which is not the primary issue in myasthenia gravis. Choice D is incorrect as it mentions inhibition of the enzyme Ache, which is not the main mechanism in this disease.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Vitamin B12 is essential for the production of red blood cells, and its deficiency can lead to pernicious anemia, characterized by decreased red blood cell production. Without adequate vitamin B12, the body cannot properly utilize iron, leading to anemia. Iron deficiency anemia (choice A) is a result of insufficient iron levels, not vitamin B12 deficiency. Sickle cell anemia (choice B) is a genetic disorder affecting hemoglobin, not related to vitamin B12 deficiency. Acquired haemolytic anemia (choice D) is caused by the premature destruction of red blood cells, not by vitamin B12 deficiency.
