Nursing Elites

1. The healthcare provider notes this rhythm on the client's cardiac monitor. The healthcare provider next reports that the client is experiencing which heart rhythm?

• A. Normal sinus
• B. Atrial fibrillation
• C. Sinus bradycardia
• D. Ventricular fibrillation

Correct answer: B

Rationale: The correct answer is B, Atrial fibrillation. Atrial fibrillation is characterized by an irregular and often rapid heart rate, which can lead to poor blood flow due to ineffective contractions of the atria. Sinus bradycardia (Choice C) is a regular but slow heart rhythm originating from the sinus node. Normal sinus rhythm (Choice A) refers to a regular heartbeat originating from the sinus node. Ventricular fibrillation (Choice D) is a life-threatening arrhythmia characterized by rapid, uncoordinated contractions of the ventricles.

2. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.

3. The healthcare provider is preparing to administer a beta blocker to a client with hypertension. What parameter should be checked before administering the medication?

• A. Serum potassium level
• B. Apical pulse
• C. Oxygen saturation
• D. Pupil reaction to light

Correct answer: B

Rationale: Before administering a beta blocker, it is crucial to check the apical pulse. Beta blockers have the potential to slow down the heart rate, making it essential to assess the pulse rate to ensure it is within the safe range before giving the medication. Checking the serum potassium level (choice A) is important when administering certain medications, but it is not specifically required before giving a beta blocker. Oxygen saturation (choice C) and pupil reaction to light (choice D) are not directly related to monitoring parameters for beta blocker administration.

4. When preparing to administer medication to a client, what action should the nurse take first?

• A. Verify the client's identity.
• B. Check the medication expiration date.
• C. Review the client's medical history.
• D. Obtain the client's vital signs.

Correct answer: A

Rationale: Verifying the client's identity is the initial and most critical step in medication administration. It is crucial to confirm that the right medication is being given to the correct patient. Checking the client's identity helps prevent medication errors and ensures patient safety. Checking the medication expiration date (choice B) is important but should come after verifying the client's identity. Reviewing the client's medical history (choice C) is valuable but not the first step in medication administration. Obtaining the client's vital signs (choice D) is essential in some situations but is usually not the first action needed before administering medication.

5. The nurse is caring for a client with coronary artery disease (CAD) who reports chest pain. The nurse administers nitroglycerin as prescribed. What is the next priority action?

• A. Obtain a 12-lead ECG
• B. Monitor the client's blood pressure
• C. Notify the healthcare provider
• D. Administer a second dose of nitroglycerin

Correct answer: B

Rationale: After administering nitroglycerin, the next priority action is to monitor the client's blood pressure. Nitroglycerin can cause vasodilation and subsequent hypotension, so it is crucial to assess the client's blood pressure to prevent complications and ensure safety. Obtaining a 12-lead ECG may be necessary but monitoring blood pressure takes precedence to detect and manage potential hypotension. Notifying the healthcare provider can be done after ensuring the client's stability. Administering a second dose of nitroglycerin without assessing the client's response and blood pressure can lead to further hypotension.
