1. A client is prescribed Clopidogrel. Which of the following laboratory values should be monitored to assess for potential adverse effects?
- A. White blood cell count
- B. Platelet count
- C. Hemoglobin
- D. Blood glucose
Correct answer: B
Rationale: Clopidogrel is an antiplatelet medication, so monitoring the client's platelet count is crucial to assess for potential bleeding complications. Changes in platelet count can indicate an increased risk of bleeding, a known adverse effect of Clopidogrel. Monitoring white blood cell count, hemoglobin, or blood glucose is not directly related to the potential adverse effects of Clopidogrel and would not provide relevant information regarding the medication's impact on platelet function.
2. When starting Alfuzosin for the treatment of Benign Prostatic Hyperplasia, a nurse is providing teaching to a client. The nurse should instruct the client that which of the following is an adverse effect of this medication?
- A. Bradycardia
- B. Edema
- C. Hypotension
- D. Tremor
Correct answer: C
Rationale: The correct adverse effect of Alfuzosin is hypotension. Alfuzosin relaxes muscle tone in veins, leading to decreased cardiac output and subsequent hypotension. Patients on this medication should be advised to change positions slowly to prevent a sudden drop in blood pressure. Choice A, Bradycardia, is not a common adverse effect of Alfuzosin. Choice B, Edema, is not typically associated with Alfuzosin use. Choice D, Tremor, is also not a common adverse effect of Alfuzosin.
3. A client is taking Epoetin Alfa for anemia. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count
- B. Platelet count
- C. Hematocrit
- D. Serum potassium level
Correct answer: C
Rationale: The nurse should monitor the hematocrit level to evaluate the effectiveness of Epoetin Alfa therapy. Epoetin Alfa stimulates red blood cell production, leading to an increase in hematocrit levels. Monitoring the hematocrit helps assess the response to therapy and ensures that the medication is effectively addressing the anemia. White blood cell count and platelet count are not directly affected by Epoetin Alfa therapy. Serum potassium level monitoring is important for other medications that may impact potassium levels but is not specifically relevant to assessing the effectiveness of Epoetin Alfa in treating anemia.
4. A client is admitted for a surgical procedure. Which preexisting condition can be a contraindication for the use of Ketamine as an intravenous anesthetic?
- A. Peptic ulcer disease
- B. Breast cancer
- C. Diabetes mellitus
- D. Schizophrenia
Correct answer: D
Rationale: Ketamine can produce psychological effects like hallucinations. Patients with schizophrenia may be more prone to experiencing exacerbation of their symptoms when exposed to Ketamine due to its potential to worsen psychotic symptoms. Therefore, schizophrenia can be a contraindication for the use of Ketamine as an anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for the use of Ketamine.
5. A healthcare professional in a provider's office is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: The correct answer is C: Potassium 3.4 mEq/L. Potassium 3.4 mEq/L is below the expected reference range and puts a client at risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, especially in older clients taking Digoxin, as potassium plays a crucial role in the heart's electrical activity. Choices A and B are related to calcium levels, which do not directly increase the risk of Digoxin toxicity. Choice D, Potassium 4.8 mEq/L, is within the expected reference range and would not increase the risk of Digoxin toxicity.
