Pathophysiology Exam 1 Quizlet

1. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). What should the nurse include in the patient education?

A. Tamoxifen may increase the risk of venous thromboembolism.
B. Tamoxifen may decrease the risk of osteoporosis.
C. Tamoxifen may cause hot flashes and other menopausal symptoms.
D. Tamoxifen may cause weight gain and fluid retention.

Correct answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about signs and symptoms of blood clots, such as swelling, pain, or redness in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with decreasing the risk of osteoporosis, causing hot flashes and menopausal symptoms, or causing weight gain and fluid retention.

2. Helicobacter pylori (H. pylori) often causes which of the following?

A. Colon cancer
B. Hiatal hernia
C. Peptic ulcer disease
D. Esophageal varices

Correct answer: C

Rationale: Helicobacter pylori is a bacterium known to cause peptic ulcer disease by weakening the protective lining of the stomach and duodenum, leading to inflammation and ulcers. While chronic H. pylori infection is a risk factor for stomach cancer, it is not directly linked to colon cancer (Choice A), hiatal hernia (Choice B), or esophageal varices (Choice D). Therefore, the correct answer is C.

3. A patient is starting on atorvastatin (Lipitor) for hyperlipidemia. What critical instruction should the nurse provide?

A. Take the medication at night to reduce the risk of muscle pain and other side effects.
B. Avoid consuming grapefruit juice while taking this medication.
C. Take the medication in the morning with breakfast to improve absorption.
D. Take the medication with a high-fat meal to increase its effectiveness.

Correct answer: A

Rationale: The correct answer is to take the medication at night to reduce the risk of muscle pain and other side effects. Atorvastatin, like other statins, is more effective when taken in the evening as the body produces more cholesterol at night. Taking it with a high-fat meal (choice D) is not recommended as it may reduce the drug's absorption. Grapefruit juice (choice B) should be avoided with atorvastatin as it can increase the risk of side effects. Taking the medication in the morning with breakfast (choice C) is not as effective as taking it at night.

4. Which immunoglobulin is the first to appear in response to a new antigen?

A. IgA
B. IgG
C. IgE
D. IgM

Correct answer: D

Rationale: The correct answer is IgM. IgM is the first immunoglobulin to appear in response to a new antigen. It is produced initially during the primary immune response. IgA is mainly found in mucosal areas and secretions. IgG is produced in a secondary immune response and is the most abundant immunoglobulin in the bloodstream. IgE is involved in allergic reactions and parasitic infections, not the initial response to a new antigen.

5. What condition can be caused by an excessive amount of growth hormone released by the pituitary gland in childhood?

A. Acromegaly
B. Gigantism
C. Syndrome of inappropriate antidiuretic hormone
D. Dwarfism

Correct answer: B

Rationale: Gigantism is the correct answer. It is a condition caused by excessive growth hormone release before the epiphyseal plates close, leading to abnormal growth. Acromegaly (choice A) is caused by excess growth hormone after the epiphyseal plates close, resulting in enlargement of bones and tissues. Syndrome of inappropriate antidiuretic hormone (choice C) is characterized by the excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia. Dwarfism (choice D) is a condition characterized by significantly below-average height.
