Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client with type 1 diabetes is found unconscious with a blood glucose of 40 mg/dL. What is the nurse's priority intervention?

• A. Administer a 50% dextrose bolus intravenously.
• B. Administer glucagon intramuscularly.
• C. Provide oral glucose gel.
• D. Recheck the blood glucose level in 15 minutes.

Correct answer: A

Rationale: The correct answer is to administer a 50% dextrose bolus intravenously. In unconscious clients with hypoglycemia, IV dextrose rapidly raises the blood glucose level. Glucagon would be a slower option and is typically used if IV access is unavailable. Oral glucose gel is not appropriate for an unconscious client as it requires swallowing and may cause aspiration. Rechecking the blood glucose level in 15 minutes delays immediate treatment and could lead to further deterioration.

3. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

4. What assessment is most important for the nurse to perform for a client with dehydration receiving IV fluids?

• A. Monitor the client’s electrolyte levels.
• B. Check the client’s urine output hourly.
• C. Assess the client’s skin turgor regularly.
• D. Monitor the client’s blood pressure every 15 minutes.

Correct answer: A

Rationale: The correct answer is to monitor the client’s electrolyte levels. When a client is receiving IV fluids for dehydration, it is crucial to assess their electrolyte levels regularly. Dehydration can lead to imbalances in electrolytes, especially sodium and potassium, which are essential for maintaining fluid balance and proper organ function. Checking urine output (Choice B) is important but not as critical as monitoring electrolyte levels. Assessing skin turgor (Choice C) is an indirect method of assessing dehydration but does not provide specific information about electrolyte imbalances. Monitoring blood pressure (Choice D) is important but not the most critical assessment in this scenario as electrolyte imbalances can have a more direct impact on the client's condition.

5. An older client who had a subtotal parathyroidectomy is preparing for discharge. What finding requires immediate provider notification?

• A. Afebrile with a normal pulse.
• B. No bowel movement since surgery.
• C. No appetite for breakfast.
• D. A positive Chvostek's sign.

Correct answer: D

Rationale: A positive Chvostek's sign indicates hypocalcemia, a complication after parathyroid surgery that requires immediate attention. This sign is manifested by facial muscle twitching when the facial nerve in front of the ear is tapped, indicating neuromuscular irritability due to low calcium levels. Afebrile with a normal pulse (Choice A) is a normal finding and does not require immediate notification. No bowel movement since surgery (Choice B) is common postoperatively due to anesthesia effects and pain medications and usually resolves within a few days; it does not require immediate notification unless accompanied by other concerning symptoms. No appetite for breakfast (Choice C) is a common postoperative finding and does not require immediate notification unless it persists and leads to dehydration or malnutrition.
