Pharmacology and the Nursing Process Test Bank

Correct Answer: A

Rationale: The correct answer is A: A urine output of 400 ml in 8 hours indicates a fluid and electrolyte imbalance induced by chemotherapy. Chemotherapy can cause renal damage, leading to decreased urine output. This can result in fluid retention and electrolyte imbalances. Choice B is incorrect because a serum potassium level of 3.6 mEq/L is within the normal range. Choice C is incorrect as the blood pressure readings provided are within the normal range. Choice D is incorrect as dry oral mucous membranes and cracked lips are more indicative of dehydration rather than a fluid and electrolyte imbalance induced by chemotherapy.

Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process checks for errors, inconsistencies, and completeness in the data. By comparing data with other sources, nurses can verify the reliability and correctness of the information. Choice A is incorrect because data validation typically occurs after data collection and before data interpretation. Choice B is incorrect because validation is about ensuring data accuracy, not about professional standards. Choice D is incorrect because data interpretation focuses on analyzing and making sense of the data, not on professional standards or validation processes.

Correct Answer: B

Rationale: The correct answer is B: Redness of the upper part of the feet. During lymphangiography, a contrast dye is injected into the lymphatic vessels. This may cause temporary redness in the upper part of the feet due to the dye spreading throughout the lymphatic system. Purplish stools (A), bluish urine (C), and coldness of the soles (D) are not expected side effects of lymphangiography and do not have a direct correlation with the procedure.

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: Confusion. Hypernatremia is an electrolyte imbalance characterized by high sodium levels in the blood. Confusion is a common symptom as high sodium levels can affect brain function. Dry skin (A) is more indicative of dehydration, tachycardia (B) is a symptom of various conditions, and pale coloring (D) is not specific to hypernatremia. Confusion is a key indicator that the nurse should assess for when monitoring for hypernatremia.
