Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A healthcare professional is reviewing the laboratory results of a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the professional report to the provider?

• A. Blood glucose level of 130 mg/dL
• B. Serum sodium level of 140 mEq/L
• C. Serum potassium level of 3.2 mEq/L
• D. Platelet count of 250,000/mm³

Correct answer: C

Rationale: A serum potassium level of 3.2 mEq/L indicates hypokalemia, a complication that should be reported in clients receiving TPN. Hypokalemia can lead to serious cardiac and neuromuscular complications. The other options are within normal ranges and do not indicate immediate concerns for a client receiving TPN. A blood glucose level of 130 mg/dL, serum sodium level of 140 mEq/L, and platelet count of 250,000/mm³ are all considered normal values and do not require immediate intervention.

3. A nurse is caring for a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. You should avoid eating foods high in potassium.
• C. You should take this medication with meals to improve absorption.
• D. Take this medication before bed to prevent drowsiness.

Correct answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.

4. A nurse is preparing to administer a controlled substance. Which of the following actions should the nurse take?

• A. Witness the waste of the controlled substance by another nurse
• B. Dispose of the controlled substance by yourself
• C. Leave the controlled substance in the client's room for later use
• D. Document the administration and sign off at the end of the shift

Correct answer: A

Rationale: The correct action for the nurse preparing to administer a controlled substance is to witness the waste of the controlled substance by another nurse. This practice is crucial to prevent misuse and ensure accurate documentation. Choice B is incorrect because disposing of the controlled substance by oneself without proper witnessing is not in accordance with safety protocols. Choice C is incorrect as leaving a controlled substance unattended in a client's room poses risks of diversion or unauthorized access. Choice D is incorrect because documenting the administration and signing off at the end of the shift is important but does not specifically address the issue of witnessing the waste of a controlled substance, which is a critical step in ensuring proper handling and accountability.

5. A parent is being taught by a nurse how to prevent sudden infant death syndrome (SIDS). Which statement by the parent indicates an understanding of how to place the infant in the crib at bedtime?

• A. Place the infant on their stomach to sleep.
• B. Place the infant on their side to sleep.
• C. Place the infant on their back to sleep.
• D. Allow the infant to sleep with a pacifier.

Correct answer: C

Rationale: The correct answer is C: 'Place the infant on their back to sleep.' This statement indicates an understanding of the recommended sleep position to reduce the risk of SIDS. Placing infants on their back is the safest sleep position according to guidelines to prevent SIDS. Choices A and B are incorrect as placing the infant on their stomach or side increases the risk of SIDS. While allowing the infant to sleep with a pacifier can also reduce the risk of SIDS, the most crucial step is placing the infant on their back for sleep.
