ATI Pathophysiology Exam 2
1. A client with multiple sclerosis (MS) is frustrated by tremors associated with the disease. How should the nurse explain why these tremors occur? Due to the demyelination of neurons that occurs in MS:
- A. there is an imbalance in acetylcholine and dopamine, leading to tremors.
- B. there is a disruption in nerve impulse conduction, causing tremors.
- C. muscles are unable to receive impulses, resulting in tremors.
- D. the reflex arc is disrupted, leading to muscle tremors.
Correct answer: B
Rationale: In multiple sclerosis (MS), demyelination of neurons disrupts nerve impulse conduction. This disruption in nerve impulses can lead to tremors, explaining why the client experiences tremors in MS. Choice A is incorrect because tremors in MS are primarily due to nerve conduction issues, not an imbalance in acetylcholine and dopamine. Choice C is incorrect as it oversimplifies the process; the issue lies in nerve impulses, not the muscle's ability to receive them. Choice D is incorrect as the primary cause of tremors in MS is the disruption in nerve impulse conduction, not the reflex arc being disrupted.
2. A client with renal calculi is admitted. What is the priority nursing intervention?
- A. Monitor urinary output every shift.
- B. Administer pain medication as ordered.
- C. Strain all urine for stones.
- D. Increase fluid intake to flush the urinary tract.
Correct answer: C
Rationale: The correct answer is to strain all urine for stones. This is the priority nursing intervention for a client with renal calculi as it helps in identifying and preventing stones from passing unnoticed. Monitoring urinary output, administering pain medication, and increasing fluid intake are important aspects of care for this client, but the priority is to ensure that any passed stones are collected and analyzed to guide further treatment.
3. What is the condition called when the client's pupils are different sizes and have been this way since childhood?
- A. Exophthalmos
- B. Anisocoria
- C. Strabismus
- D. Scleral edema
Correct answer: B
Rationale: Anisocoria is the correct answer. Anisocoria is the condition of having pupils of different sizes. Exophthalmos refers to abnormal protrusion of the eyeball, not pupil size difference. Strabismus is a condition where the eyes are not properly aligned with each other. Scleral edema is swelling of the sclera, the white part of the eye, and not related to differing pupil sizes.
4. A nurse is caring for a client who has a new prescription for metformin. Which of the following findings in the client's medical history should the nurse report to the provider?
- A. History of hypertension
- B. History of polycystic ovary syndrome
- C. History of asthma
- D. History of kidney disease
Correct answer: D
Rationale: The correct answer is D, history of kidney disease. Metformin should be used with caution in clients with kidney disease due to the risk of lactic acidosis, a serious complication. Reporting this finding to the provider is crucial for assessing the appropriateness of continuing metformin therapy. Choices A, B, and C do not contraindicate the use of metformin, so they are not the priority for reporting.
5. A healthcare provider at an urgent care clinic is assessing an adolescent client who has an upper respiratory tract infection. Which of the following findings should the provider recognize as a manifestation of pertussis?
- A. Inflamed throat with exudate
- B. Purulent eye drainage
- C. Dry, hacking cough
- D. Koplik spots on buccal mucosa
Correct answer: C
Rationale: The correct answer is C: 'Dry, hacking cough.' A dry, hacking cough is a classic manifestation of pertussis. Pertussis typically presents with symptoms of an upper respiratory tract infection, starting with a persistent, severe, and uncontrollable cough that can worsen at night. This cough is often followed by a high-pitched 'whoop' sound as the patient tries to catch their breath, hence the term 'whooping cough.' In contrast, options A, B, and D are not typically associated with pertussis. Inflamed throat with exudate may suggest a bacterial throat infection like streptococcal pharyngitis, purulent eye drainage is more indicative of a bacterial conjunctivitis, and Koplik spots on the buccal mucosa are specific to measles. Therefore, recognizing the dry, hacking cough as a manifestation of pertussis is crucial for early identification and appropriate management of the disease.
