1. A 5-year-old female takes a hike through the woods during a school field trip. Upon returning home, she hugs her father, and he later develops poison ivy. Which of the following immune reactions is he experiencing?

Correct answer: D

Rationale: The father's immune reaction to poison ivy is an example of cell-mediated immunity, specifically a type IV hypersensitivity reaction. In this type of reaction, sensitized T cells react to antigens, leading to inflammation and tissue damage. IgE-mediated reactions involve antibodies of the IgE class, commonly seen in allergic responses like anaphylaxis. Tissue-specific reactions target specific organs or tissues. Immune complex reactions involve immune complexes formed by antigens and antibodies that can deposit in tissues, leading to inflammation.

2. A patient is starting on alendronate (Fosamax) for the treatment of osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

Correct answer: A

Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Taking the medication with milk (choice B) is not recommended as it may interfere with alendronate absorption. Taking it at bedtime (choice C) is not necessary and may increase the risk of esophageal irritation. Taking the medication with food (choice D) can reduce its absorption and effectiveness.

3. What is the distinguishing feature of Hodgkin disease noted on histologic exam?

Correct answer: A

Rationale: The correct answer is A: Reed-Sternberg cells. Reed-Sternberg cells are large, abnormal B-cells that are characteristic of Hodgkin's lymphoma. These cells are identified on histologic examination of lymph node biopsies from patients with Hodgkin disease. Choice B, 'Red-stained cells,' is vague and does not describe a specific feature of Hodgkin disease. Choice C, 'Human Papillomavirus,' is incorrect as Hodgkin disease is not caused by HPV. Choice D, 'B-cells and T-cells,' is incorrect as Hodgkin disease is characterized by the presence of Reed-Sternberg cells, which are abnormal B-cells.

4. Stress-induced cortisol hormone secretion is associated with:

Correct answer: B

Rationale: The correct answer is B: Regulation of the stress response. Cortisol plays a crucial role in regulating the body's response to stress by modulating various physiological processes. Choices A, C, and D are incorrect because stress-induced cortisol hormone secretion is not directly associated with increased growth hormone levels, increased thyroid-stimulating hormone, or depressed adrenal gland function.

5. Which of the following are risk factors for hypertension (HTN)?

Correct answer: C

Rationale: Tobacco use is a well-established risk factor for hypertension (HTN) as it can lead to increased blood pressure. High sugar intake and low-fat diets, as well as increased physical activity, are not directly associated with hypertension. While low-fat diets are generally recommended for overall health, they are not specifically linked to hypertension risk.
