Nursing Elites

1. A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?

• A. aPTT 75 seconds.
• B. INR 1.2.
• C. Hemoglobin 10 g/dL.
• D. Fibrinogen level 350 mg/dL.

Correct answer: A

Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.

2. How should a healthcare professional monitor for infection in a patient with a central line?

• A. Check the central line dressing daily
• B. Monitor for signs of redness
• C. Check for abnormal breath sounds
• D. Monitor temperature

Correct answer: A

Rationale: Correct answer: A. Checking the central line dressing daily is crucial to monitor for signs of infection around the insertion site. This practice helps in early detection of any changes such as redness, swelling, or discharge, which are indicators of a potential infection. Monitoring for signs of redness (choice B) is limited as redness alone may not always indicate an infection; other symptoms like discharge and tenderness should also be observed. Checking for abnormal breath sounds (choice C) is not directly related to monitoring central line infections. Monitoring temperature (choice D) is important for detecting systemic signs of infection but may not specifically indicate an infection related to the central line site.

3. A nurse is providing teaching to a client who has been prescribed digoxin for heart failure. Which of the following instructions should the nurse include?

• A. Take this medication with meals.
• B. Check your pulse before taking this medication.
• C. Take this medication with an antacid to reduce stomach upset.
• D. Increase your potassium intake while taking this medication.

Correct answer: B

Rationale: The correct answer is B: 'Check your pulse before taking this medication.' When a patient is prescribed digoxin, it is crucial to monitor their pulse rate because digoxin can cause bradycardia (slow heart rate) as a side effect. In contrast, choices A, C, and D are incorrect. Taking digoxin with meals is not necessary; it should be taken consistently at the same time every day. Taking digoxin with an antacid is not recommended as it can interfere with the absorption of the medication. While digoxin can cause hypokalemia (low potassium levels), patients should not increase their potassium intake without healthcare provider guidance to avoid potential complications.

4. A healthcare professional is assessing a client who has chronic kidney disease. Which of the following findings is an indication for hemodialysis?

• A. BUN 16 mg/dL
• B. Serum magnesium 1.8 mg/dL
• C. Serum phosphorus 4.0 mg/dL
• D. Glomerular filtration rate of 14 mL/min

Correct answer: D

Rationale: A glomerular filtration rate of 14 mL/min indicates severe kidney impairment and the need for hemodialysis. The other choices, such as BUN 16 mg/dL, serum magnesium 1.8 mg/dL, and serum phosphorus 4.0 mg/dL, are within normal ranges and do not directly indicate the need for hemodialysis in chronic kidney disease.

5. A healthcare professional is reviewing the medical record of a client who has a new prescription for enoxaparin. Which of the following findings should the healthcare professional report to the provider?

• A. Platelet count 150,000/mm³
• B. aPTT 30 seconds
• C. Sodium 140 mEq/L
• D. Serum creatinine 3.0 mg/dL

Correct answer: D

Rationale: An elevated serum creatinine level indicates impaired kidney function, which can affect the metabolism and excretion of enoxaparin, potentially leading to increased drug levels and risk of bleeding. Therefore, it is crucial to report a high serum creatinine level before administering enoxaparin. Platelet count, aPTT, and sodium levels are not directly related to the administration of enoxaparin and would not impact its use; hence, they do not need to be reported before starting the medication.
