ATI Pathophysiology
1. A toddler is displaying signs/symptoms of weakness and muscle atrophy. The pediatric neurologist suspects it may be a lower motor neuron disease called spinal muscular atrophy (SMA). The client's family asks how he got this. The nurse will respond:
- A. This could result from playing in soil and then ingesting bacteria that is now attacking his motor neurons.
- B. No one really knows how this disease is formed. We just know that in time, he may grow out of it.
- C. This is a degenerative disorder that tends to be inherited as an autosomal recessive trait.
- D. This is a segmental demyelination disorder that affects all nerve roots and eventually all muscle groups as well.
Correct answer: C
Rationale: The correct answer is C. Spinal muscular atrophy (SMA) is an inherited disorder, often autosomal recessive, that affects lower motor neurons. Choice A is incorrect because SMA is not caused by ingesting bacteria from playing in soil. Choice B is incorrect as SMA is not something that a person grows out of. Choice D is incorrect because SMA is not a demyelination disorder that affects nerve roots and muscle groups.
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. Anemia of chronic inflammation is generally classified as:
- A. hypochromic and microcytic.
- B. hypochromic and macrocytic.
- C. normochromic and microcytic.
- D. normochromic and normocytic.
Correct answer: D
Rationale: Anemia of chronic inflammation is characterized by normochromic and normocytic red blood cells. In chronic inflammation, the body typically produces enough red blood cells, but they are often smaller and paler than normal (normocytic and normochromic). Choices A, B, and C are incorrect because hypochromic and microcytic, hypochromic and macrocytic, and normochromic and microcytic anemias are not typically associated with chronic inflammation.
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. Which information would indicate more teaching is needed regarding hypersensitivity reactions? Type _______ hypersensitivity reactions involve an antibody response.
- A. I
- B. II
- C. III
- D. IV
Correct answer: D
Rationale: The correct answer is D: Type IV hypersensitivity reactions involve cell-mediated immunity, not an antibody response. This question tests knowledge of hypersensitivity reactions and their classification. Type I hypersensitivity reactions involve IgE antibodies, Type II involves IgG or IgM antibodies, and Type III involves immune complex deposition. Type IV hypersensitivity reactions are delayed and involve T cells, not antibodies. Therefore, if a person believes that Type IV hypersensitivity reactions involve an antibody response, more teaching is required.
