thrombocytopenia is which disorder below

ATI RN

ATI Pathophysiology Exam 1

1. Thrombocytopenia is which disorder below?

A. Increased blood coagulation
B. Increased platelet production
C. Increased number of infections
D. Decreased platelet production

Correct answer: D

Rationale: Thrombocytopenia is a disorder characterized by a decreased platelet count or decreased platelet production, which affects blood clotting. Choice A, 'Increased blood coagulation,' is incorrect as thrombocytopenia is associated with decreased platelets, leading to impaired clotting. Choice B, 'Increased platelet production,' is incorrect as thrombocytopenia is characterized by a decrease in platelet production. Choice C, 'Increased number of infections,' is unrelated to thrombocytopenia, which primarily involves low platelet levels.

2. In which of the following cases is dehydration more likely to occur?

A. A 50-year-old woman who is a bodybuilder
B. A 50-year-old man who is morbidly obese
C. A 10-year-old child who is thin
D. A 30-year-old with multiple sclerosis

Correct answer: B

Rationale: The correct answer is B. Morbid obesity increases the risk of dehydration due to the larger body surface area and potential for greater insensible losses. Choices A, C, and D are less likely to experience dehydration compared to a morbidly obese individual.

3. A client diagnosed with Bell's palsy is receiving discharge teaching from a nurse. Which statement made by the client indicates an understanding of the condition?

A. I should avoid moving my face excessively to prevent worsening of symptoms.
B. This condition usually resolves on its own within a few weeks or months.
C. Bell's palsy is caused by a stroke and requires immediate medical treatment.
D. I will need to take antiviral medication for the rest of my life to manage this condition.

Correct answer: B

Rationale: The correct answer is B. Bell's palsy typically resolves on its own within a few weeks to months. Choice A is incorrect because gentle facial exercises are often encouraged to prevent muscle weakness. Choice C is incorrect as Bell's palsy is not caused by a stroke but by inflammation of the facial nerve. Choice D is incorrect as antiviral medication is usually given early in the diagnosis but not required for lifelong management.

4. A hemoglobin electrophoresis is done to evaluate for sickle cell disease. The report reveals the person has HbAS, which means the person:

A. is normal with no sickle cell disease.
B. is a sickle cell carrier.
C. has sickle cell anemia.
D. has thalassemia.

Correct answer: B

Rationale: The correct answer is that the person is a sickle cell carrier. In HbAS, 'Hb' stands for hemoglobin, 'A' indicates normal hemoglobin, and 'S' indicates the sickle cell trait. Individuals with HbAS are carriers of the sickle cell trait but do not have sickle cell disease. Choice A is incorrect because having the sickle cell trait means carrying the gene for sickle cell disease. Choice C is incorrect as sickle cell anemia is a different condition where individuals have two copies of the abnormal hemoglobin gene, resulting in the disease. Choice D is incorrect because thalassemia is a separate genetic disorder affecting the production of hemoglobin, not related to the sickle cell trait.

5. A patient is taking alendronate (Fosamax) for osteoporosis. 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.
B. Take the medication at bedtime to ensure absorption during sleep.
C. Take the medication with milk to enhance calcium absorption.
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 at bedtime (choice B) is not recommended as it can lead to esophageal irritation when lying down. Taking the medication with milk (choice C) is incorrect as it may interfere with the absorption of alendronate. Taking the medication with food (choice D) is not recommended as it may reduce the effectiveness of the medication.
