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. 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.

3. A male client reports numbness and tingling in his fingers and around his mouth. What laboratory value should the nurse review?

• A. Capillary glucose.
• B. Serum calcium.
• C. Urine specific gravity.
• D. White blood cell count.

Correct answer: B

Rationale: The correct answer is B, Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia, a condition characterized by low calcium levels in the blood. Reviewing the client's serum calcium levels is crucial in this situation to assess for hypocalcemia. Choice A, Capillary glucose, is incorrect because symptoms described are not typically associated with glucose abnormalities. Choice C, Urine specific gravity, and Choice D, White blood cell count, are unrelated to the symptoms presented and are not indicative of the client's condition.

4. An older adult client with gastroenteritis has been taking the antidiarrheal diphenoxylate for the past 24 hours. What finding requires the nurse to take further action?

• A. Monitor the client’s fluid intake.
• B. Obtain a stool sample for testing.
• C. Administer a laxative to clear the infection.
• D. Assess skin turgor and provide fluids.

Correct answer: D

Rationale: The correct answer is D. Assessing skin turgor is crucial as tented skin turgor indicates dehydration, which can be worsened by antidiarrheal medications like diphenoxylate. Providing fluids is essential to address dehydration in this client. Monitoring fluid intake (choice A) is important, but assessing skin turgor takes precedence in this situation. Obtaining a stool sample for testing (choice B) could be necessary for diagnostic purposes but is not the immediate priority. Administering a laxative (choice C) is contraindicated in this case as it can worsen the client's condition by further exacerbating fluid loss.

5. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.
