Pharmacology and the Nursing Process 10th Edition Test Bank Questions

Question 1 of 5

Mr Santos is scheduled for CT SCAN for the next day, noon time. Which of the following is the correct preparation as instructed by the nurse?

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.

Question 2 of 5

Mrs. Zeno continues to become a weaker despite .treatment with neostigmine. Edrophonium HCL is ordered:

Correct Answer: C

Rationale: The correct answer is C: To rule out cholinergic crisis caused by Neostigmine. Edrophonium HCL is a fast-acting cholinesterase inhibitor used to differentiate between myasthenic crisis and cholinergic crisis. If the patient's weakness improves after administration of edrophonium, it indicates that the weakness was due to myasthenia gravis and not cholinergic crisis caused by excessive neostigmine. Choice A is incorrect because there is no synergestic effect between neostigmine and edrophonium. Choice B is incorrect as resistance to neostigmine is not a valid reason for ordering edrophonium. Choice D is incorrect because edrophonium is used for differential diagnosis, not for confirming the diagnosis of myasthenia gravis.

Question 3 of 5

In planning an educational session for a patient with HIV, the nurse would include which of the following as a method of transmission for HIV? i.Saliva iv.Semen ii.Tears v.Blood iii.Breast milk

Correct Answer: C

Rationale: The correct answer is C: 3, 4, 2005. HIV can be transmitted through breast milk, blood, and semen due to the presence of the virus in these bodily fluids. Saliva, tears, and other body fluids do not typically contain enough of the virus to transmit HIV. Therefore, choices A, B, and D are incorrect as they include saliva, tears, and other non-transmissible fluids. It is crucial for the nurse to educate the patient on the modes of transmission to prevent the spread of HIV.

Question 4 of 5

Nurse Karen is caring for a client with chronic renal failure. Which is a correct intervention for hyperkalemia?

Correct Answer: B

Rationale: The correct answer is B because hyperkalemia presents with symptoms such as muscle weakness, diarrhea, and ECG changes. Muscle weakness is a common sign due to potassium's effect on neuromuscular function. Diarrhea can lead to potassium loss. ECG changes, such as peaked T waves and widened QRS complexes, indicate cardiac involvement. Assessing for these symptoms helps monitor the severity of hyperkalemia and guide treatment. Other choices are incorrect because assessing for fever and chest pain (choice A) are not specific to hyperkalemia. Encouraging fluid restriction (choice C) may not directly address hyperkalemia. Preparing for a cardiac ultrasound (choice D) is not an immediate intervention for hyperkalemia.

Question 5 of 5

Mr Santos is scheduled for CT SCAN for the next day, noon time. Which of the following is the correct preparation as instructed by the nurse?

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.
