Nursing Elites

1. A nurse is caring for a client with a newly inserted pacemaker. What is the most important nursing action post-procedure?

• A. Monitor the insertion site for signs of infection.
• B. Educate the client about activity restrictions.
• C. Monitor the client's heart rate and rhythm.
• D. Assess the client's lung sounds for signs of fluid overload.

Correct answer: A

Rationale: Post-procedure, monitoring the insertion site for signs of infection is crucial because it helps in early detection of any potential complications such as infection. While educating the client about activity restrictions, monitoring the client's heart rate and rhythm, and assessing lung sounds for signs of fluid overload are important aspects of care, the immediate priority post-procedure is to prevent infection at the insertion site, which could lead to serious complications.

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. When starting on oral contraceptives, what important information should the nurse provide regarding the timing of the medication?

• A. Oral contraceptives must be taken at the same time each day to maintain consistent hormone levels and ensure effectiveness in preventing pregnancy.
• B. Oral contraceptives can be taken at any time of day as long as the schedule is consistent.
• C. Oral contraceptives should be taken with food to enhance absorption.
• D. Oral contraceptives can be skipped occasionally without significant consequences.

Correct answer: A

Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain consistent hormone levels and ensure effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential for optimal efficacy. Choice C is inaccurate as oral contraceptives do not need to be taken with food for absorption. Choice D is incorrect because missing doses or skipping oral contraceptives can reduce their effectiveness in preventing pregnancy.

4. During childhood, the thymus decreases in size, and this is referred to as ______ atrophy.

• A. Physiologic
• B. Pathologic
• C. Disuse
• D. Neurogenic

Correct answer: A

Rationale: The correct answer is A, 'Physiologic.' Physiologic atrophy is a normal part of development, like the reduction in thymus size during childhood. Pathologic atrophy (choice B) refers to tissue wasting due to disease, not a normal process like the reduction in thymus size. Disuse atrophy (choice C) results from a lack of physical activity or stimulation, which is not the case with thymus size reduction. Neurogenic atrophy (choice D) is caused by damage to or diseases of the nerves supplying the muscles, not related to the thymus size reduction seen in childhood.

5. A 30-year-old male was diagnosed with HIV. Which of the following treatments would be most effective?

• A. Reverse transcriptase inhibitors
• B. Protease inhibitors
• C. Entrance inhibitors
• D. Highly active antiretroviral therapy

Correct answer: D

Rationale: The correct answer is D: Highly active antiretroviral therapy (HAART). HAART involves a combination of different classes of antiretroviral drugs, which can effectively suppress the HIV virus, reduce the viral load, and improve the immune function. While choices A, B, and C are also used in HIV treatment, the most effective approach is a combination therapy like HAART due to its ability to target the virus at different stages of its life cycle, reducing the risk of drug resistance and improving treatment outcomes.
