ATI Pathophysiology Exam 2

1. What laboratory tests should the nurse monitor regularly when a male patient is receiving androgen therapy?

A. Monitor liver function tests regularly.
B. Monitor renal function tests regularly.
C. Monitor blood glucose levels regularly.
D. Monitor complete blood count (CBC) regularly.

Correct answer: A

Rationale: The correct answer is to monitor liver function tests regularly when a male patient is receiving androgen therapy. Androgen therapy can impact liver function, making it crucial to monitor liver function tests to assess any potential adverse effects on the liver. Renal function tests (choice B) are not typically affected by androgen therapy and do not need specific monitoring for this treatment. Blood glucose levels (choice C) are more relevant in conditions like diabetes or with medications affecting blood sugar, not typically in androgen therapy. Complete blood count (CBC) (choice D) is not directly impacted by androgen therapy and is not a priority for monitoring in this context.

2. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?

A. Ribavirin (Rebetol)
B. Ganciclovir (Cytovene) IV
C. Foscarnet (Foscavir) IV
D. Valganciclovir hydrochloride (Valcyte)

Correct answer: A

Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.

3. A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug. How should the nurse best respond to the patient's question?

A. “Multiple drugs are used because doctors need to combat the TB bacteria from different angles to effectively treat the infection.”
B. “The use of multiple drugs prevents the development of drug-resistant TB.”
C. “Multiple drugs are prescribed because the final testing results for TB can take up to 3 weeks to confirm the most effective treatment.”
D. “Multiple drugs are used in order to speed up the course of treatment.”

Correct answer: B

Rationale: The correct answer is B. Using multiple drugs in tuberculosis treatment helps prevent the development of drug-resistant TB. This approach is crucial because if the infection is not completely eradicated, the remaining bacteria may become resistant to the single drug used, making future treatments less effective. Choice A is incorrect because the use of multiple drugs is not due to uncertainty about which drug will work, but rather to address the bacteria from different angles. Choice C is incorrect as it misleads the patient about the reason for using multiple drugs. Choice D is also incorrect because the primary purpose of using multiple drugs is not to speed up treatment but to ensure effectiveness and prevent resistance.

4. What are the major mechanisms of spinal cord injuries?

A. Hypoextension, expansion, hyperflexion
B. Hyperflexion, expansion, hypometabolism
C. Hypermetabolism, compression, hyperextension
D. Hyperextension, hyperflexion, compression

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.

5. What is responsible for initiating clonal selection?

A. B cells
B. T cells
C. Antigens
D. Lymphocytes

Correct answer: C

Rationale: Antigens are the correct answer as they are the molecules that trigger the immune response by binding to specific B or T cells. This binding activates these cells, leading to their proliferation and differentiation to fight off the antigen. B cells and T cells are the responders to antigens, not the initiators of clonal selection. Lymphocytes is a broad term encompassing both B and T cells, so it is not the specific factor responsible for initiating clonal selection.
