Nursing Elites

1. A client is diagnosed with HIV. Which of the following antiviral drug classes are used in the treatment of HIV/AIDS?

• A. nucleoside reverse transcriptase inhibitors
• B. protease inhibitors
• C. HIV fusion inhibitors
• D. all of the above

Correct answer: D

Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.

2. A client has been placed in isolation because he is diagnosed with a contagious illness. The nurse should be aware that:

• A. Linens from the client's bed should be double-bagged.
• B. Meals should be served on washable dishes.
• C. Extensive isolation rarely causes psychological problems.
• D. Paper trays and plastic utensils do not prevent disease transmission.

Correct answer: A

Rationale: Isolation techniques are used to prevent or limit the spread of infection. Special handling of articles and linens soiled by any body fluid is essential. Linens should be placed in impervious bags before being removed from the client's bedside to prevent exposure of personnel and contamination of the environment. Double-bagging is required if the outside of the bag becomes contaminated. This practice ensures that potentially infectious materials are properly contained and disposed of. Choices B, C, and D are incorrect because the focus in this scenario is on proper handling and disposal of soiled linens to prevent the spread of infection, not on serving meals, psychological effects of isolation, or the use of paper trays and plastic utensils.

3. Which of the following foods might a client with hypercholesterolemia need to decrease intake of?

• A. broiled catfish
• B. hamburgers
• C. wheat bread
• D. fresh apples

Correct answer: B

Rationale: A client with hypercholesterolemia should decrease their intake of foods high in cholesterol. Hamburgers, being red meat, have a high cholesterol content, hence should be decreased in the diet. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol, so there is no need to decrease their intake. Broiled catfish is a lean source of protein, wheat bread is a complex carbohydrate, and fresh apples are a good source of fiber and vitamins. Therefore, hamburgers are the correct choice to decrease intake for a client with hypercholesterolemia.

4. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

• A. Brown-S�quard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

5. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.
