a nurse is assessing a client with suspected myasthenia gravis which symptom would the nurse expect to find

Pathophysiology Practice Exam

1. A healthcare professional is assessing a client with suspected myasthenia gravis. Which symptom would the healthcare professional expect to find?

A. Muscle atrophy
B. Facial weakness
C. Ptosis and diplopia
D. Increased muscle tone

Correct answer: C

Rationale: Ptosis (drooping eyelid) and diplopia (double vision) are classic symptoms of myasthenia gravis. Muscle atrophy (Choice A) is not a typical early manifestation of myasthenia gravis. While facial weakness (Choice B) can occur, it is not as specific as ptosis and diplopia. Increased muscle tone (Choice D) is more indicative of conditions like spasticity, not myasthenia gravis.

2. A patient with endometriosis is prescribed medroxyprogesterone acetate (Provera). What should the nurse include in the patient education?

A. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
B. Medroxyprogesterone can be taken with food to reduce gastrointestinal upset.
C. Medroxyprogesterone should be discontinued if side effects occur.
D. Medroxyprogesterone should be taken once a week to maintain effectiveness.

Correct answer: A

Rationale: When educating a patient with endometriosis who is prescribed medroxyprogesterone acetate (Provera), the nurse should emphasize the importance of taking the medication at the same time each day. This helps maintain consistent hormone levels and ensures the effectiveness of the treatment. Option A is correct. Option B is incorrect because medroxyprogesterone should be taken consistently, regardless of food intake. Option C is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Option D is incorrect because medroxyprogesterone is typically taken daily, not weekly, for the treatment of endometriosis.

3. What is the primary cause of primary hypercholesteremia?

A. High-density lipoprotein (HDL) defects
B. Monogenic mutations, sedentary lifestyle, and high cholesterol diet
C. Polygenic mutations and environmental factors
D. Low-density lipoprotein (LDL) receptor mutation with defects in breakdown

Correct answer: D

Rationale: The correct answer is 'Low-density lipoprotein (LDL) receptor mutation with defects in breakdown.' Primary hypercholesteremia is mainly caused by mutations in the LDL receptor, leading to impaired clearance of LDL cholesterol from the blood. This results in high levels of LDL cholesterol in the bloodstream. Choices A, B, and C are incorrect because they do not directly relate to the primary cause of primary hypercholesteremia.

4. A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What instructions should the nurse provide to ensure the effectiveness of the medication?

A. Take the medication with a full glass of water and remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption.
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. Taking the medication with milk (choice B) is not recommended as it may interfere with the absorption of alendronate. Taking the medication at bedtime (choice C) is not necessary for optimal absorption. Taking the medication with food (choice D) is also not recommended as food can reduce the absorption of alendronate.

5. Which of the following is a cause of hypothyroidism?

A. Overproduction of cortisol
B. Autoimmune destruction of the thyroid gland
C. Overactivity of the thyroid gland
D. Insufficient iodine intake

Correct answer: B

Rationale: The correct answer is B: Autoimmune destruction of the thyroid gland. In hypothyroidism, the thyroid gland does not produce enough hormones to meet the body's needs. This can be due to autoimmune destruction of the thyroid gland, where the body's immune system mistakenly attacks the thyroid tissue. Choices A, C, and D are incorrect. Overproduction of cortisol is associated with conditions like Cushing's syndrome, overactivity of the thyroid gland is a characteristic of hyperthyroidism, and insufficient iodine intake can lead to goiter but not necessarily hypothyroidism.
