Nursing Elites

1. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

2. When administering ceftriaxone sodium (Rocephin) intravenously to a client, which assessment finding requires the most immediate intervention by the nurse?

• A. Stridor
• B. Nausea
• C. Headache
• D. Pruritus

Correct answer: A

Rationale: The correct answer is A: Stridor. Stridor is a high-pitched, noisy breathing sound that indicates a potential airway obstruction, which can be caused by an allergic reaction. This finding requires immediate intervention by the nurse to ensure the client's airway is patent and to prevent respiratory distress. Nausea, headache, and pruritus are potential side effects of ceftriaxone sodium but do not pose immediate life-threatening risks compared to airway obstruction indicated by stridor.

3. A client with hyperthyroidism who has not been responsive to medications is admitted for evaluation. What action should the nurse implement?

• A. Notify the healthcare provider.
• B. Review the client's medication history.
• C. Prepare the client for thyroid function tests.
• D. Initiate seizure precautions.

Correct answer: A

Rationale: In a scenario where a client with hyperthyroidism is not responding to medications, the nurse's priority action should be to notify the healthcare provider. This is important because the client may require immediate intervention, such as adjusting the treatment plan or exploring alternative therapies. Reviewing the client's medication history (choice B) may be relevant but not as urgent as involving the healthcare provider. While preparing the client for thyroid function tests (choice C) may be necessary as part of the evaluation process, it is not the most immediate action to take. Initiating seizure precautions (choice D) is not directly related to the non-responsiveness of medications in hyperthyroidism and is not a priority in this situation.

4. A client with heart failure is prescribed furosemide (Lasix). Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 100/60 mmHg
• C. Presence of a new murmur
• D. Crackles in the lungs

Correct answer: D

Rationale: The correct answer is D: Crackles in the lungs. Crackles indicate fluid overload in the lungs, a critical sign in a client with heart failure. This finding suggests that the furosemide may not be effectively managing the fluid balance, and immediate intervention is required. Choices A, B, and C are not immediate concerns in this scenario. A heart rate of 60 beats per minute, a blood pressure of 100/60 mmHg, and the presence of a new murmur are findings that may require monitoring or intervention but are not as urgent as crackles in the lungs in a client with heart failure.

5. A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme inhibitor (ACEI). Which instruction should the nurse include in the medication teaching plan?

• A. Increase intake of potassium-rich foods
• B. Report increased bruising or bleeding
• C. Stop medication if a cough develops
• D. Limit intake of leafy green vegetables

Correct answer: B

Rationale: The correct instruction for the nurse to include in the medication teaching plan for a client receiving enalapril, an ACE inhibitor, is to 'Report increased bruising or bleeding.' ACE inhibitors can cause thrombocytopenia, which can lead to an increased risk of bruising and bleeding. Monitoring and reporting these symptoms promptly are essential to prevent complications. Choices A, C, and D are incorrect because increasing potassium-rich foods, stopping medication if a cough develops, and limiting intake of leafy green vegetables are not directly related to the common side effects or actions of ACE inhibitors.
