1. Which electrolyte imbalance should be closely monitored in a patient receiving digoxin?
- A. Monitor potassium levels
- B. Monitor sodium levels
- C. Monitor calcium levels
- D. Monitor glucose levels
Correct answer: A
Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.
2. Which lab value is critical for a patient on heparin therapy?
- A. Monitor aPTT
- B. Monitor INR
- C. Monitor platelet count
- D. Monitor sodium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.
3. A nurse is planning care for a client who is receiving total parenteral nutrition (TPN). Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Serum calcium level
- B. Blood glucose level
- C. Serum albumin level
- D. Serum sodium level
Correct answer: C
Rationale: The correct answer is C, Serum albumin level. Monitoring the serum albumin level helps assess the nutritional effectiveness of total parenteral nutrition (TPN). Serum albumin is a protein that reflects the long-term nutritional status of a patient. Serum calcium level (choice A) is not directly related to TPN effectiveness. Blood glucose level (choice B) is important to monitor in diabetic patients but is not the primary indicator of TPN efficacy. Serum sodium level (choice D) is more related to fluid balance and electrolyte status rather than the effectiveness of TPN.
4. A client with type 2 diabetes mellitus is scheduled for an arteriogram. Which of the following medications should the nurse instruct the client to discontinue 48 hours prior to the procedure?
- A. Atorvastatin
- B. Digoxin
- C. Nifedipine
- D. Metformin
Correct answer: D
Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.
5. A nurse is assessing a client who has syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following findings should the nurse expect?
- A. Increased urine output
- B. Increased serum sodium
- C. Hyponatremia
- D. Hypercalcemia
Correct answer: C
Rationale: In clients with Syndrome of Inappropriate Antidiuretic Hormone (SIADH), the nurse should expect hyponatremia. SIADH leads to excess water retention, diluting the sodium levels in the blood, resulting in low serum sodium levels. Choice A, increased urine output, is incorrect as SIADH causes water retention, leading to decreased urine output. Choice B, increased serum sodium, is incorrect because SIADH causes a dilutional effect due to water retention, resulting in decreased serum sodium levels. Choice D, hypercalcemia, is unrelated to SIADH and not a typical finding.
