1. What potential risk should the nurse identify as being associated with infliximab (Remicade) in the treatment of rheumatoid arthritis?

Correct answer: A

Rationale: The correct answer is A: Risk for infection. Infliximab (Remicade) is a medication used to treat autoimmune conditions like rheumatoid arthritis. One of the main risks associated with infliximab is an increased susceptibility to infections due to its immunosuppressive effects. This drug works by targeting specific proteins in the body's immune system, which can weaken the body's ability to fight off infections. Choices B, C, and D are incorrect because infliximab is not typically associated with decreased level of consciousness, nephrotoxicity, or hepatotoxicity. It is important for healthcare providers to monitor patients on infliximab for signs of infection and educate them on the importance of infection prevention strategies.

2. Which of the following conditions is associated with a positive Homan's sign?

Correct answer: A

Rationale: A positive Homan's sign is indicative of deep vein thrombosis. This sign is elicited by dorsiflexing the foot of a patient with the knee slightly flexed, resulting in calf pain. Peripheral artery disease (choice B) is associated with decreased blood flow to the extremities, but it does not produce a positive Homan's sign. Varicose veins (choice C) are enlarged, twisted veins that are typically not related to Homan's sign. Lymphedema (choice D) is swelling caused by a lymphatic system blockage or dysfunction and is not linked to Homan's sign.

3. A patient is being administered chemotherapeutic agents for the treatment of cancer. Which of the following blood cells will be stimulated by the colony-stimulating factors in response to the effects of the chemotherapy?

Correct answer: A

Rationale: The correct answer is White blood cells. Colony-stimulating factors stimulate the production of white blood cells in response to the effects of chemotherapy, as it can lead to myelosuppression. Red blood cells are not directly stimulated by colony-stimulating factors. Phagocytes are a type of white blood cell involved in immune responses, but they are not specifically stimulated by colony-stimulating factors. Myocardial cells are cardiac muscle cells and are not directly involved in the response to chemotherapy-induced myelosuppression.

4. As you are walking in the park, a huge black Labrador runs up to you and places his paws on your shoulders. Immediately your heart starts racing, you feel palpitations, anxiety, and your hands become a little shaky. The nurse knows that this response is primarily caused by:

Correct answer: D

Rationale: The autonomic nervous system controls involuntary bodily functions like heart rate, respiration, and sweating. In the given scenario, the 'fight or flight' response is activated, leading to increased heart rate, palpitations, anxiety, and shaky hands. The cerebral cortex is involved in conscious thought processes and decision-making, not the immediate physiological response observed here. The somatic nervous system regulates voluntary movements, while the limbic system is responsible for emotions and memory, but the autonomic nervous system is primarily responsible for the physiological responses seen in this situation.

5. A 30-year-old man has a history of heart transplant and is receiving long-term steroids to prevent rejection. The patient is due for routine vaccines. Attenuated vaccines are contraindicated in this patient because the antigen is:

Correct answer: A

Rationale: The correct answer is A: live and can cause infection. Patients who are immunocompromised, like those receiving long-term steroids after an organ transplant, should not receive live vaccines because the live attenuated organisms in these vaccines can cause infections in individuals with weakened immune systems. Choice B is incorrect because attenuated vaccines are live but weakened, not mutated. Choice C is incorrect because while inactive, attenuated vaccines are not infectious. Choice D is incorrect because attenuated vaccines are not pathogenic; they are attenuated (weakened) forms of the pathogen.
