1. What specific instructions should the nurse provide for a patient starting on alendronate (Fosamax) for osteoporosis to ensure proper administration?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
- B. Take the medication with milk to enhance calcium absorption.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with food to prevent nausea.
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. Choice B is incorrect because alendronate should not be taken with milk, as it can interfere with its absorption. Choice C is incorrect as there is no specific instruction to take alendronate at bedtime. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.
2. 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?
- A. White blood cells
- B. Red blood cells
- C. Phagocytes
- D. Myocardial cells
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.
3. A 45-year-old client is admitted with new-onset status epilepticus. What is the priority nursing intervention?
- A. Administer IV fluids and monitor electrolytes.
- B. Administer antiepileptic medications as prescribed.
- C. Ensure a patent airway and prepare for possible intubation.
- D. Monitor the client for signs of hypotension.
Correct answer: C
Rationale: The correct answer is C. In a client with new-onset status epilepticus, the priority nursing intervention is to ensure a patent airway and prepare for possible intubation. This is crucial to prevent hypoxia and further complications. Administering IV fluids and monitoring electrolytes (choice A) can be important but ensuring airway patency takes precedence. Administering antiepileptic medications (choice B) is essential but only after securing the airway. Monitoring for hypotension (choice D) is also important but not the priority when managing status epilepticus.
4. 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.
5. An experiment is designed to determine specific cell types involved in cell-mediated immune response. The experimenter is interested in finding cells that attack cells that have specific antigens. Which cells should be isolated?
- A. Lymphokine-producing cells
- B. Cytotoxic T cells
- C. Helper T cells
- D. Macrophages
Correct answer: B
Rationale: Cytotoxic T cells are the key players in cell-mediated immunity as they directly attack cells displaying specific antigens. Lymphokine-producing cells (Choice A) are involved in cytokine production, while Helper T cells (Choice C) assist in activating other immune cells. Macrophages (Choice D) are phagocytic cells that engulf and digest pathogens, but they are not the primary cells responsible for directly attacking cells with specific antigens in cell-mediated immunity.
