Nursing Elites

1. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

2. What is the most critical lab value to monitor for a patient on heparin therapy?

• A. Monitor aPTT levels
• B. Monitor platelet count
• C. Monitor INR levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.

3. A client with a history of angina reports substernal chest pain that radiates to the left arm. Which of the following actions should the nurse take first?

• A. Administer nitroglycerin sublingually.
• B. Administer 2L of oxygen via nasal cannula.
• C. Administer aspirin 325 mg orally.
• D. Obtain a 12-lead ECG.

Correct answer: D

Rationale: In a client with a history of angina experiencing chest pain radiating to the left arm, obtaining a 12-lead ECG is the priority action to assess for myocardial infarction. An ECG helps in diagnosing and evaluating the extent of cardiac ischemia or infarction. Administering nitroglycerin, oxygen, or aspirin can follow once the ECG has been performed to confirm the diagnosis and guide further interventions. Administering nitroglycerin sublingually is often appropriate for angina but should not precede the ECG in this urgent scenario. Oxygen therapy and aspirin administration are important interventions but obtaining the ECG takes precedence in assessing for acute cardiac events.

4. A client sustained a major burn over 20% of the body. What intervention should the nurse implement to meet the client's nutritional needs?

• A. Keep track of calorie intake for food and beverages.
• B. Provide a low-protein, high-carbohydrate diet.
• C. Schedule meals at 6-hour intervals.
• D. Provide a high-protein, high-calorie diet.

Correct answer: D

Rationale: The correct answer is to provide a high-protein, high-calorie diet for a client with major burns. This type of diet is essential to support healing and recovery. High-protein intake is crucial as it helps in tissue repair and wound healing, while high-calorie intake is necessary to meet the increased metabolic demands of the body during the healing process. Keeping track of calorie intake (Choice A) is important but doesn't address the specific needs of a burn patient. Providing a low-protein, high-carbohydrate diet (Choice B) is not suitable for burn patients as they require adequate protein for wound healing. Scheduling meals at 6-hour intervals (Choice C) may be helpful for maintaining a consistent eating schedule, but it is not as crucial as providing the correct high-protein, high-calorie diet.

5. A healthcare professional is preparing to administer ceftriaxone IM to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication using a tuberculin syringe
• B. Administer the medication at a 45-degree angle
• C. Use the dorsogluteal muscle for injection
• D. Aspirate for blood return before injecting the medication

Correct answer: D

Rationale: Correct Answer: When administering intramuscular injections like ceftriaxone, it is essential to aspirate for blood return before injecting the medication to ensure that the needle is not in a blood vessel. Choices A and B are incorrect because ceftriaxone is typically administered using a syringe appropriate for IM injections (not a tuberculin syringe) and injected at a 90-degree angle rather than 45 degrees. Choice C is incorrect because the dorsogluteal site is no longer recommended for IM injections due to potential injury to the sciatic nerve and other structures.
