1. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?
- A. True
- B. False
- C. Not applicable
- D. Not applicable
Correct answer: True
Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.
2. A healthcare provider is caring for a client who has a new prescription for Epoetin Alfa. Which of the following laboratory values should the healthcare provider monitor?
- A. WBC count.
- B. Platelet count.
- C. Hemoglobin.
- D. Serum potassium.
Correct answer: C
Rationale: Epoetin alfa is a medication that stimulates red blood cell production, so hemoglobin levels should be monitored to assess the effectiveness of the drug. Monitoring hemoglobin levels helps evaluate the response to Epoetin Alfa treatment and ensures that the client's anemia is being appropriately managed.
3. A client is starting therapy with cisplatin. The healthcare provider should instruct the client to report which of the following adverse effects?
- A. Tinnitus
- B. Nausea
- C. Constipation
- D. Weight gain
Correct answer: A
Rationale: The correct answer is tinnitus. Cisplatin can cause ototoxicity, which may manifest as tinnitus. Tinnitus should be reported promptly to the healthcare provider to prevent further hearing damage.
4. What is a condition where the heart's ability to pump blood is reduced because the heart muscle is enlarged, thickened, or stiffened?
- A. Cardiomyopathy
- B. Endocarditis
- C. Myocarditis
- D. Aortic stenosis
Correct answer: A
Rationale: Cardiomyopathy is the correct answer. It is a condition characterized by the enlargement, thickening, or stiffening of the heart muscle, leading to a reduced ability of the heart to pump blood effectively. Endocarditis (Choice B) is the inflammation of the inner lining of the heart chambers and valves, not specifically related to the heart muscle. Myocarditis (Choice C) is inflammation of the heart muscle typically caused by a viral infection, not directly related to the heart muscle's structure. Aortic stenosis (Choice D) is a condition characterized by the narrowing of the aortic valve opening, affecting blood flow from the heart's left ventricle to the aorta, different from the structural changes seen in cardiomyopathy.
5. A child is being cared for following a head injury. Which of the following findings should indicate to the healthcare provider that the child is developing diabetes insipidus?
- A. Urine specific gravity of 1.045
- B. Sodium level of 155
- C. Blood glucose level of 45
- D. Urine output of 35 ml per hour
Correct answer: B
Rationale: In a child with a head injury, the development of diabetes insipidus can occur due to pituitary hypofunction, leading to a deficiency of antidiuretic hormone. An elevated sodium level (hypernatremia) is a key finding in diabetes insipidus due to the excessive loss of free water in the urine, resulting in increased sodium concentration in the blood.
