Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. It causes the most deaths in women because it is often diagnosed at advanced stages when treatment options are limited. Breast cancer, although common, has a higher survival rate. Brain cancer is relatively rare compared to lung cancer. Colon and rectal cancer, while prevalent, do not surpass lung cancer in terms of mortality rates in women.

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: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important preprocedure teaching for carotid angiography because it prepares the patient for a common sensation during the procedure, helping to manage their expectations and reduce anxiety. This information is crucial for informed consent. Choice A is incorrect because carotid angiography is usually done under local anesthesia, not general anesthesia. Choice B is incorrect as carotid angiography typically takes about 1-2 hours, not several hours. Choice D is incorrect because all medical procedures, including carotid angiography, carry potential risks and complications, which should be discussed with the patient.

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.

Correct Answer: A

Rationale: The correct answer is A: Fluid intake of less than 2,500mL. In diabetes insipidus, the body cannot properly regulate fluid balance, leading to excessive thirst and urination. Successful treatment aims to manage these symptoms by reducing fluid intake to prevent dehydration. Therefore, a decrease in fluid intake indicates successful treatment. Explanation for incorrect choices: B: Blood pressure of 90/50mmHg - Blood pressure is not directly related to the treatment of diabetes insipidus. C: Pulse rate of 126 beats/min - Pulse rate is not a specific indicator of successful treatment for diabetes insipidus. D: Urine output of more than 200mL/hour - In diabetes insipidus, excessive urine output is a symptom of the condition, so an increase in urine output does not indicate successful treatment.
