Nursing Elites

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

• A. Type I
• B. Type II
• C. Type III
• D. Type IV

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. The nurse is caring for a client with an astrocytoma. The client asks, 'What do astrocytes do in the brain?' What is the nurse's best response?

• A. Astrocytes help to nourish and support neurons in the brain.
• B. Astrocytes are a type of neuron that transmit electrical signals.
• C. Astrocytes are involved in immune responses in the brain.
• D. Astrocytes help regulate blood flow in the brain.

Correct answer: A

Rationale: Astrocytes play a crucial role in supporting and nourishing neurons by providing metabolic support, maintaining the blood-brain barrier, and regulating the chemical environment of the brain. While astrocytes are essential for brain function, they are not neurons and do not transmit electrical signals (Choice B). Astrocytes are not primarily involved in immune responses in the brain (Choice C) or in regulating blood flow in the brain (Choice D), although they indirectly influence blood flow through their support functions.

3. A patient is prescribed acyclovir (Zovirax) for the treatment of genital herpes. What is the expected outcome of this medication?

• A. Decreased testosterone production
• B. Decreased libido
• C. Decreased viral shedding
• D. Decreased bacterial replication

Correct answer: C

Rationale: The expected outcome of acyclovir (Zovirax) for the treatment of genital herpes is decreased viral shedding. Acyclovir is an antiviral medication that works by inhibiting the replication of the herpes virus, thereby reducing viral shedding and helping to control outbreaks. Choice A, decreased testosterone production, and Choice B, decreased libido, are unrelated outcomes of acyclovir treatment for genital herpes. Choice D, decreased bacterial replication, is also incorrect as acyclovir specifically targets viruses and does not affect bacterial replication.

4. 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.

5. When communicating with a client who has cognitive impairment, which of the following will Nurse Dory use?

• A. Complete explanations with multiple details
• B. Pictures or gestures instead of words
• C. Stimulating words and phrases to capture the client’s attention
• D. Short words and simple sentences

Correct answer: D

Rationale: Nurse Dory will use short words and simple sentences when communicating with a client who has cognitive impairment. This approach is effective because it helps improve understanding and comprehension for individuals with cognitive challenges. Choice A is incorrect because complete explanations with multiple details may overwhelm or confuse clients with cognitive impairment. Choice B is not the most effective option as using pictures or gestures instead of words may not always be practical or necessary. Choice C is also not ideal as stimulating words and phrases may cause distraction rather than enhance communication for clients with cognitive impairment.
