Adult Health Exam 1
1. The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?
- A. 15 mL
- B. 10 mL
- C. 20 mL
- D. 5 mL
Correct answer: A
Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.
2. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. What is the primary purpose of this medication?
- A. To lower blood pressure
- B. To improve appetite
- C. To increase red blood cell production
- D. To reduce fluid retention
Correct answer: C
Rationale: The correct answer is C: 'To increase red blood cell production.' Erythropoietin stimulates the production of red blood cells to treat anemia associated with CKD. Choices A, B, and D are incorrect because erythropoietin therapy is primarily used to address anemia by increasing the production of red blood cells rather than lowering blood pressure, improving appetite, or reducing fluid retention.
3. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?
- A. Approximately 26 cm
- B. Between 24 to 28 cm
- C. Above the umbilicus by two finger widths
- D. Below the xiphoid process
Correct answer: B
Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
4. A client admitted to the hospital with advanced liver failure related to chronic alcoholism is exhibiting ascites and edema. Which pathophysiological mechanisms should the nurse identify as responsible for the third spacing symptoms? (Select all that apply.)
- A. Portal hypertension.
- B. Sodium and water retention.
- C. Decreased serum albumin.
- D. All of the above
Correct answer: D
Rationale: In advanced liver failure related to chronic alcoholism, ascites and edema occur due to multiple pathophysiological mechanisms. Portal hypertension contributes to the development of ascites by increasing pressure in the portal venous system. Sodium and water retention exacerbate fluid accumulation in the third space. Decreased serum albumin levels lead to reduced oncotic pressure, contributing to the movement of fluid into the interstitial spaces. Abnormal protein metabolism further disrupts fluid balance. Therefore, all of the options (A, B, and C) are correct in this scenario, making choice D the correct answer. Choices A, B, and C alone do not fully explain the comprehensive pathophysiological mechanisms involved in the development of ascites and edema in this clinical context.
5. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?
- A. Check blood pressure.
- B. Assess heart rate.
- C. Monitor respiratory rate.
- D. Measure oxygen saturation.
Correct answer: B
Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.
