Nursing Elites

1. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

2. A nurse is assessing a client who is receiving enteral feedings through a nasogastric tube. Which of the following findings requires immediate intervention?

• A. Aspirating 100 mL of gastric residual
• B. Gastric pH of 4
• C. Auscultating crackles in the lung bases
• D. Checking residual every 6 hours

Correct answer: C

Rationale: Auscultating crackles in the lung bases indicates fluid in the lungs, which can be a sign of aspiration pneumonia or pulmonary edema and requires immediate intervention to prevent respiratory distress. Aspirating 100 mL of gastric residual is within the acceptable range and does not require immediate intervention. A gastric pH of 4 is normal for gastric contents. Checking residual every 6 hours is a routine nursing intervention and does not indicate an urgent issue like pulmonary complications.

3. A client in active labor is being assessed by a nurse. Which of the following findings should the nurse report to the provider?

• A. Contractions lasting 80 seconds.
• B. FHR baseline of 170/min.
• C. Early decelerations in the FHR.
• D. Temperature of 37.4°C (99.3°F).

Correct answer: B

Rationale: The correct answer is B because a baseline FHR of 170/min indicates fetal tachycardia, which needs further evaluation. Choice A about contractions lasting 80 seconds is within the normal range for active labor. Choice C, early decelerations in the FHR, are generally considered benign and do not require immediate reporting. Choice D, a temperature of 37.4°C (99.3°F), falls within normal limits for a laboring client and does not warrant immediate reporting.

4. A nurse is assessing a client who is postoperative following a thyroidectomy. The nurse should identify which of the following findings as an indication of hypocalcemia?

• A. Tingling in the fingers.
• B. Elevated blood pressure.
• C. Positive Chvostek's sign.
• D. Positive Kernig's sign.

Correct answer: A

Rationale: The correct answer is A: Tingling in the fingers. Tingling in the fingers is a common sign of hypocalcemia, often seen after a thyroidectomy. Hypocalcemia can occur post-thyroidectomy due to inadvertent damage or removal of the parathyroid glands which regulate calcium levels. Choices B, C, and D are incorrect. Elevated blood pressure is not typically associated with hypocalcemia. Positive Chvostek's sign is a clinical sign of hypocalcemia but is usually assessed as facial muscle twitching, not tingling in the fingers. Positive Kernig's sign is a test for meningitis, not related to hypocalcemia.

5. A nurse is teaching a client who has a new prescription for lisinopril. Which of the following statements should the nurse include?

• A. You should expect to develop a dry cough while taking this medication.
• B. This medication can cause a slow heart rate.
• C. You should increase your intake of foods high in potassium.
• D. You should avoid using salt substitutes while taking this medication.

Correct answer: D

Rationale: The correct statement to include when teaching a client prescribed with lisinopril is that they should avoid using salt substitutes while taking this medication. Lisinopril can cause hyperkalemia, which is an elevated level of potassium in the blood. Therefore, using salt substitutes that contain potassium can worsen this condition. Choices A, B, and C are incorrect because lisinopril is not typically associated with causing a dry cough or a slow heart rate, and increasing potassium intake can be harmful in the presence of lisinopril-induced hyperkalemia.
