Nursing Elites

1. How should a healthcare professional administer a subcutaneous injection?

• A. Insert the needle at a 45-degree angle
• B. Insert the needle at a 90-degree angle
• C. Use a Z-track method
• D. Insert the needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.

2. A nurse is caring for a client who has Cushing's syndrome. Which of the following findings should the nurse expect?

• A. Hypotension.
• B. Weight loss.
• C. Hyperkalemia.
• D. Hypercalcemia.

Correct answer: C

Rationale: In clients with Cushing's syndrome, the nurse should expect hyperkalemia. Cushing's syndrome is characterized by excess cortisol levels, which can lead to potassium retention and result in hyperkalemia. Choices A, B, and D are incorrect. Hypotension is not typically associated with Cushing's syndrome; instead, hypertension is more common due to the effects of cortisol. Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome. Hypercalcemia is not a typical finding in Cushing's syndrome; instead, hypocalcemia may occur due to increased urinary calcium excretion.

3. What is the best method to assess for fluid overload in patients with heart failure?

• A. Monitor daily weight
• B. Check for jugular vein distention
• C. Check for pitting edema
• D. Check for fluid retention

Correct answer: A

Rationale: The correct answer is A: Monitor daily weight. Daily weight monitoring is the most accurate method to assess fluid overload in patients with heart failure. Changes in weight can indicate fluid retention before visible signs like jugular vein distention or pitting edema appear. Checking for jugular vein distention (choice B) is helpful but may not be as sensitive as daily weight monitoring. Pitting edema (choice C) and fluid retention (choice D) are signs of fluid overload, but daily weight monitoring is a more proactive approach to detect changes early.

4. A client has a new diagnosis of hypertension and is being taught about lifestyle changes by a nurse. Which of the following instructions should the nurse include?

• A. Increase your sodium intake to 3,000 mg per day.
• B. Exercise for 30 minutes at least 5 days a week.
• C. Sleep for at least 10 hours each night.
• D. Limit your fluid intake to 1 liter per day.

Correct answer: B

Rationale: The correct answer is B: "Exercise for 30 minutes at least 5 days a week." Regular exercise helps promote cardiovascular health and manage hypertension. Choice A is incorrect because increasing sodium intake is not recommended for hypertension. Choice C is incorrect because while sleep is important, excessive sleep duration is not typically part of hypertension management. Choice D is incorrect because fluid intake should be adequate unless advised otherwise by a healthcare provider.

5. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.
