Pathophysiology Practice Questions
1. Which of the following chronic inflammatory skin disorders is characterized by angiogenesis, immune cell activation (particularly T cells), and keratinocyte proliferation?
- A. Psoriasis
- B. Melanoma
- C. Atopic dermatitis
- D. Urticaria
Correct answer: A
Rationale: Psoriasis is the correct answer. Psoriasis is a chronic inflammatory skin disorder characterized by angiogenesis, immune cell activation (particularly T cells), and keratinocyte proliferation. Choice B, Melanoma, is a type of skin cancer involving melanocytes, not characterized by the features mentioned. Choice C, Atopic dermatitis, is a different inflammatory skin condition associated with pruritus and eczematous lesions, not primarily characterized by angiogenesis. Choice D, Urticaria, is a skin condition characterized by hives and wheals due to histamine release, not typically involving the features mentioned in the question.
2. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:
- A. positively charged.
- B. inhibitory.
- C. overstimulated.
- D. dormant.
Correct answer: B
Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.
3. When a Tae Kwon Do (TKD) master applies downward pressure just above the elbow joint on an attacker who immediately collapses to the ground, which reflex is applicable to this example?
- A. Golgi tendon reflex
- B. Myotatic reflex
- C. Withdrawal reflex
- D. Crossed-extensor reflex
Correct answer: A
Rationale: The Golgi tendon reflex is the correct answer. This reflex protects the muscle and tendons from excessive force by causing the muscle to relax. In this scenario, the downward pressure applied just above the elbow joint triggers the Golgi tendon reflex, resulting in the attacker's collapse. The other options are incorrect: - The myotatic reflex (also known as the stretch reflex) is responsible for contracting a muscle in response to its stretch, not relaxing it. - The withdrawal reflex is a spinal reflex that moves a body part away from a painful stimulus, not directly related to the scenario described. - The crossed-extensor reflex is a reflex that occurs on the opposite side of the body in response to a withdrawal reflex, which is not the case in this situation.
4. What nursing diagnosis is suggested by the patient's statement regarding taking extra griseofulvin when she thinks her infection is getting worse?
- A. Deficient knowledge related to correct use of griseofulvin
- B. Effective therapeutic regimen management related to symptom identification
- C. Disturbed thought processes related to appropriate use of griseofulvin
- D. Ineffective coping related to self-medication
Correct answer: C
Rationale: The correct answer is C: 'Disturbed thought processes related to appropriate use of griseofulvin.' The patient's statement shows a misunderstanding of the correct use of griseofulvin by taking extra medication when she believes her infection is worsening. This behavior indicates a disturbance in her thought process regarding the appropriate use of the medication. Choice A is incorrect because the issue is not lack of knowledge but rather a misunderstanding leading to inappropriate actions. Choice B is incorrect as the patient's actions do not demonstrate effective management of her therapeutic regimen. Choice D is incorrect as the patient is not engaged in self-medication but rather misinterpreting signals and self-adjusting the prescribed medication.
5. Which of the following birthmarks usually fade or regress as the child gets older?
- A. Hemangiomas
- B. Congenital dermal melanocytosis (i.e., Mongolian spots)
- C. Macular stains
- D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains
Correct answer: D
Rationale: The correct answer is D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains are birthmarks that usually fade or regress as the child gets older. Hemangiomas are vascular birthmarks that often shrink and fade over time. Congenital dermal melanocytosis (Mongolian spots) are blue-gray birthmarks commonly found on the lower back and buttocks of infants, which typically fade by adolescence. Macular stains, also known as salmon patches, are pink or red birthmarks that usually fade within the first few years of life. Choice D is correct because all the mentioned birthmarks tend to diminish as the child grows, unlike choices A, B, and C which do not fade or regress with age.
