Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. A client with diabetes insipidus is admitted due to a pituitary tumor. What complication should the nurse monitor closely?

• A. Monitor for elevated blood pressure.
• B. Monitor for ketonuria.
• C. Monitor for peripheral edema.
• D. Monitor for hypokalemia.

Correct answer: D

Rationale: The correct answer is to monitor for hypokalemia. In diabetes insipidus, excessive urination can lead to electrolyte imbalances, particularly low potassium levels (hypokalemia). The loss of potassium through increased urination can result in muscle weakness, cardiac dysrhythmias, and other serious complications. Elevated blood pressure (Choice A) is not a typical complication of diabetes insipidus due to pituitary tumors. Ketonuria (Choice B) is more commonly associated with diabetes mellitus due to inadequate insulin levels. Peripheral edema (Choice C) is not a direct complication of diabetes insipidus.

3. 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.

4. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

5. A toddler presenting with a history of intermittent skin rashes, hives, abdominal pain, and vomiting that occurs after ingesting milk products arrives at the clinic accompanied by the parents. Which type of testing should the nurse educate the toddler's family about?

• A. Complete blood count
• B. Lactose tolerance test
• C. Skin allergy testing
• D. Serum immunoglobulin E

Correct answer: D

Rationale: The correct answer is D, Serum immunoglobulin E (IgE) testing. This test can help diagnose food allergies, including milk protein allergies, in toddlers presenting with symptoms like skin rashes, hives, abdominal pain, and vomiting after consuming milk products. Skin allergy testing is used for allergies but may not be suitable for this age group due to developmental factors. Lactose intolerance, which is different from a milk allergy, is assessed through a lactose tolerance test, not IgE testing. A complete blood count (CBC) would not provide specific information related to food allergies.
