1. A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct answer: C
Rationale: Erythropoietin is a hormone that primarily stimulates the bone marrow to produce more red blood cells. By increasing red blood cell production, erythropoietin helps to improve oxygen delivery to tissues, which is essential in managing anemia. Choices A, B, and D are incorrect because erythropoietin specifically targets red blood cell production and does not have a direct effect on white blood cells, platelets, or clotting factors.
2. An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?
- A. Corticosteroids
- B. Gamma globulin
- C. Hepatitis B vaccine
- D. Fresh frozen plasma
Correct answer: B
Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection. Therefore, the correct choice is Gamma globulin as it can provide immediate passive immunity against hepatitis B.
3. A client who is acutely ill has vigilant oral care included in their plan of care. What factor increases this client's risk for dental caries?
- A. Hormonal changes induced by the stress response leading to an acidic oral environment
- B. Systemic infections commonly affecting the teeth
- C. Intravenous hydration lacking fluoride
- D. Inadequate nutrition and reduced saliva production contributing to cavities
Correct answer: D
Rationale: Inadequate nutrition and decreased saliva production can lead to a conducive environment for the development of dental caries. Without proper nutrition and sufficient saliva, the protective mechanisms against cavities are compromised, making the individual more susceptible to tooth decay.
4. A patient with bipolar disorder is prescribed valproic acid. What is an important side effect for the nurse to monitor?
- A. Hypertension
- B. Liver toxicity
- C. Hyperglycemia
- D. Bradycardia
Correct answer: B
Rationale: The correct answer is B: Liver toxicity. Valproic acid is known to potentially cause liver toxicity. Monitoring liver function tests regularly in patients taking valproic acid is crucial to detect any signs of liver damage early and prevent serious complications.
5. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?
- A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
- B. Absent peristalsis and elevated LES pressure
- C. Absent peristalsis and decreased LES pressure
- D. Vigorous peristalsis and decreased LES pressure
Correct answer: C
Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.
