ATI Pathophysiology Final Exam

1. A patient has suffered from several infections in the last 6 months and unexplained impaired wound healing. What assessment should the nurse prioritize?

A. Assess for pain.
B. Assess for nutritional deficiencies.
C. Assess genetic tendency for infection.
D. Assess for edema and decreased hemoglobin.

Correct answer: B

Rationale: In this scenario, the patient's history of multiple infections and impaired wound healing indicates a potential issue with their immune system and overall health. Therefore, the nurse should prioritize assessing for nutritional deficiencies. Proper nutrition is essential for a healthy immune response and wound healing. Assessing for pain (choice A) may be important but addressing the root cause of the recurrent infections and impaired wound healing is crucial. Genetic tendency for infection (choice C) would be a less immediate concern compared to assessing for nutritional deficiencies. Edema and decreased hemoglobin (choice D) are not the most relevant assessments based on the patient's symptoms.

2. Which of the following accurately describes the pathophysiology of asthma?

A. Chronic inflammation of the bronchial lining
B. Narrowing of the airway due to bronchoconstriction
C. Damage to alveoli reducing lung elasticity
D. Overproduction of mucus by the goblet cells

Correct answer: B

Rationale: The correct answer is B: "Narrowing of the airway due to bronchoconstriction." In asthma, there is an inflammatory response that leads to bronchoconstriction, causing the airways to narrow and making it difficult to breathe. Choice A is incorrect as chronic inflammation is a feature of asthma but not the primary pathophysiological mechanism. Choice C is incorrect as damage to alveoli is more characteristic of conditions like emphysema. Choice D is incorrect as overproduction of mucus is a feature of chronic bronchitis, not asthma.

3. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

A. Peptic ulcer disease
B. History of myocardial infarction
C. Recent use of antihypertensive medications
D. Use of nitrates

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.

4. Multiple sclerosis manifests as asymmetrical and in different parts of the body because:

A. Autoreactive lymphocytes are causing diffuse patchy damage to the myelin sheath in the central nervous system.
B. Acetylcholine receptors are destroyed by immunoglobulin G.
C. Autoreactive T lymphocytes cause progressive loss of neurons in the substantia nigra.
D. Cortical motor cells degenerate.

Correct answer: A

Rationale: The correct answer is A. Multiple sclerosis is characterized by the immune system attacking the myelin sheath in the central nervous system. This attack leads to patchy damage on the myelin sheath, resulting in asymmetrical neurological symptoms. Choices B, C, and D are incorrect because they do not accurately describe the pathophysiology of multiple sclerosis. In multiple sclerosis, it is the autoreactive lymphocytes that target and damage the myelin sheath, not acetylcholine receptors, T lymphocytes, or cortical motor cells.

5. How often should a patient be administered a tetanus toxoid?

A. Every year
B. Every 10 years
C. Every 2 years
D. Every 5 years

Correct answer: B

Rationale: Tetanus toxoid should be administered every 10 years to ensure continued protection against tetanus infection. The correct answer is 'Every 10 years.' Choice A ('Every year') is incorrect as the frequency is too frequent. Choice C ('Every 2 years') is incorrect as it is too frequent for tetanus toxoid administration. Choice D ('Every 5 years') is incorrect as it does not align with the recommended interval for tetanus toxoid booster doses.
