Pharmacology and the Nursing Process 9th Edition Test Bank Questions
Question 1 of 9
Mr. Reyes is extremely confused. The nurse provide new information slowly and in small amounts because;
Correct Answer: A
Rationale: The correct answer is A: Confusion or delirium can be a defense against further stress. This is because providing new information slowly and in small amounts can help prevent overwhelming Mr. Reyes, who is already confused. This approach allows him to process and understand the information more effectively without adding to his stress levels. Choices B, C, and D are incorrect: B: Destruction of brain cells has occurred, interrupting mental activity - This is not the most appropriate explanation as it assumes irreversible damage to the brain, which is not mentioned in the question. C: Teaching based on information progressing from the simple to the complex - While this may be a valid teaching strategy in general, it does not address Mr. Reyes' specific state of confusion and the need to reduce stress. D: A minimum of information should be given, since he is unaware of surrounding - This choice does not address the underlying reason for providing information slowly, which is to manage stress and confusion, rather than solely focusing on the
Question 2 of 9
For the first 72 hours thyroidectomy surgery, the nurse would assess the client for Chvostek’s sign and Trousseau’s sign because they indicate which of the following?
Correct Answer: A
Rationale: The correct answer is A: Hypocalcemia. Chvostek's sign and Trousseau's sign are both indicators of hypocalcemia, which is a common complication following thyroidectomy surgery due to potential damage to the parathyroid glands. Chvostek's sign is elicited by tapping the facial nerve and observing facial muscle twitching, while Trousseau's sign involves carpal spasm induced by inflating a blood pressure cuff above systolic pressure. Both signs are sensitive indicators of hypocalcemia due to their association with neuromuscular irritability. Hypercalcemia (option C) and hyperkalemia (option D) are not typically associated with thyroidectomy surgery and would not present with these specific signs. Hypokalemia (option B) is not related to Chvostek's sign and Trousseau's sign.
Question 3 of 9
Which of the ff. statements, if made by a patient with hypertension, indicates to a nurse a need for more teaching?
Correct Answer: C
Rationale: Step-by-step rationale: 1. Statement C indicates a misunderstanding that medication can be stopped when feeling better, which is incorrect. 2. Hypertension is a chronic condition that often requires lifelong medication. 3. This demonstrates a lack of understanding regarding the necessity of long-term management. 4. Statements A, B, and D show knowledge about hypertension's effects, dietary management, and awareness, respectively. Summary: Statement C is incorrect as it suggests stopping medication, while statements A, B, and D show accurate understanding of hypertension.
Question 4 of 9
The client with myasthenia gravis has become increasingly weaker. The physician prepares to identify whether the client is reacting to an overdose of the medication (cholinergic crisis) or an increasing severity of the disease (myasthenic crisis). An injection of edrophonium (Tensilon) is administered. Which of the following would indicate that the client is in cholinergic crisis?
Correct Answer: B
Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.
Question 5 of 9
The physician orders furosemide (Lasix) 40 mg IV STAT for an acutely fluid-overloaded patient. Why was the IV route likely chosen?
Correct Answer: B
Rationale: The correct answer is B: IV is the route of choice for rapid administration. IV route allows for quick onset of action, crucial in acutely fluid-overloaded patients needing immediate diuresis. Option A is incorrect as furosemide can be given orally too. Option C is less relevant in this urgent situation where speed is key. Option D is also incorrect as the side effects are not determined by route of administration.
Question 6 of 9
Nurse Dennis provides health promotion to a group of male adults. He is correct when he states that clients with cirrhosis should include which measure to adhere to a home?
Correct Answer: C
Rationale: The correct answer is C: limit daily alcohol intake. This is crucial for clients with cirrhosis as alcohol can exacerbate liver damage. Limiting alcohol intake helps prevent further harm to the liver and promotes overall health. Supplementation with multivitamins (choice A) can be beneficial, but not as essential as avoiding alcohol. Taking sleeping pills (choice B) may worsen liver function and is not recommended. Limiting contact at all times (choice D) is irrelevant to managing cirrhosis.
Question 7 of 9
An adult who has gastroenteritis and is on digitalis ha lab values of: K 3.2 mEq/L, Na 136 mEq/L, Ca 8.8 mg/dl, and Cl 98 mEq/L. the nurse puts which of the following on the client’s plan of care?
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct: 1. The lab value of K at 3.2 mEq/L indicates hypokalemia. 2. Digitalis can worsen hypokalemia and lead to toxicity. 3. Avoiding foods rich in potassium will prevent further lowering of potassium levels. 4. This intervention helps prevent potential digitalis toxicity in the client. Summary of why the other choices are incorrect: A. Stopping digitalis therapy abruptly can lead to rebound effects and worsen the condition. B. Trousseau's and Chvostek's signs are not relevant to the client's current lab values. D. While observing for digitalis toxicity is important, addressing the low potassium level is a more immediate concern in this scenario.
Question 8 of 9
The most effective pharmacologic agent for the treatment of Parkinson’s disease is:
Correct Answer: A
Rationale: The correct answer is A: Levodopa. Levodopa is the most effective pharmacologic agent for Parkinson's disease as it is converted to dopamine in the brain, replenishing dopamine levels which are depleted in Parkinson's. Selegiline and Symmetrel provide symptomatic relief but are not as effective as Levodopa. Permax is not commonly used due to its association with serious side effects like heart valve damage.
Question 9 of 9
A nurse is evaluating goals and expected outcomes for a confused patient. Which finding indicates positive progress toward resolving the confusion? NursingStoreRN
Correct Answer: D
Rationale: The correct answer is D because the patient correctly stating names of family members in the room indicates improved cognitive function and memory recall, which are positive signs of progress in resolving confusion. This demonstrates improved orientation and ability to recognize familiar individuals. Choices A and B indicate safety concerns and risk of falls, which are not related to resolving confusion. Choice C indicates pain management and mobility but does not directly reflect improvement in cognitive status.
