1. A patient presents with a rash from poison ivy. The nurse knows that this is which type of hypersensitivity?

Correct answer: D

Rationale: A rash from poison ivy is an example of a type IV hypersensitivity reaction. Type IV hypersensitivity reactions are delayed cell-mediated immune responses involving T cells. This type of reaction is characterized by a delayed onset, typically occurring 48-72 hours after exposure to the antigen. Choice A, Type I hypersensitivity reactions, are immediate hypersensitivity reactions mediated by IgE antibodies. Choices B and C, Type II and Type III hypersensitivity reactions, involve antibody-mediated cytotoxicity and immune complex deposition, respectively, which are not characteristic of poison ivy-induced rashes.

2. Which of the following is a cause of edema?

Correct answer: A

Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice B) is low blood pressure and is not a direct cause of edema. Dehydration (choice C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice D) is excessive urination and not a direct cause of edema.

3. An MRI scan of a 33-year-old female client with new-onset seizures has revealed a lesion on her frontal lobe. Which of the following signs and symptoms would most likely be a direct result of this lesion?

Correct answer: C

Rationale: The correct answer is C: Changes in speech and reasoning. The frontal lobe is responsible for higher cognitive functions, including speech and reasoning. A lesion in this area can lead to difficulties in speech production, language comprehension, and reasoning abilities. Choices A, B, and D are incorrect. Changes in sensation or movement in the client's limbs are more associated with lesions in the motor or sensory cortices of the brain, not the frontal lobe. Fluctuations in blood pressure are often related to autonomic nervous system dysfunction, which is controlled by other brain regions. Increased intracranial pressure is typically seen in conditions like brain tumors or head trauma, not directly related to a frontal lobe lesion.

4. Staff at the care facility note that a woman has started complaining of back pain in recent weeks and occasionally groans in pain. She has many comorbidities that require several prescription medications. The nurse knows that which factor is likely to complicate the clinician's assessment and treatment of the client's pain?

Correct answer: B

Rationale: Polypharmacy, or the use of multiple medications, can complicate pain management due to drug interactions and side effects. While advanced age can influence pain perception, it is not the most likely factor to complicate assessment and treatment in this scenario. Underlying conditions may affect pain perception but do not directly complicate the management process. Cognitive decline can hinder pain assessment, but in this case, the focus is on factors directly impacting the treatment process, making option B the most appropriate choice.

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.
