Nursing Elites

1. A client arrives in the emergency room with a possible fractured femur. The nurse should anticipate an order for:

• A. Trendelenburg position
• B. Ice to the entire extremity
• C. Buck's traction
• D. An abduction pillow

Correct answer: C

Rationale: The correct answer is Buck's traction. This intervention is used to realign the fractured femur, reduce spasms, and alleviate pain. Placing the client in the Trendelenburg position is inappropriate for a femur fracture, making answer A incorrect. While ice may be used post-repair, applying it to the entire extremity is unnecessary, so answer B is wrong. An abduction pillow is typically employed following a total hip replacement, not for a fractured femur, rendering answer D incorrect.

2. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

3. Before administering Theodur to a 10-year-old being treated for asthma, the nurse should check the:

• A. Urinary output
• B. Blood pressure
• C. Pulse
• D. Temperature

Correct answer: C

Rationale: The correct answer is to check the pulse. Theodur is a bronchodilator used in asthma treatment, and one of the side effects is tachycardia (increased heart rate). Therefore, it is essential to assess the pulse rate before administering Theodur to monitor for any potential tachycardia. Checking urinary output (Choice A), blood pressure (Choice B), and temperature (Choice D) are not directly related to the immediate side effects of bronchodilators like Theodur in this context, making them unnecessary assessments.

4. The client is receiving heparin for thrombophlebitis of the left lower extremity. Which of the following drugs reverses the effects of heparin?

• A. Cyanocobalamin
• B. Protamine sulfate
• C. Streptokinase
• D. Sodium warfarin

Correct answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.

5. The nurse is assessing the client recently returned from surgery. The nurse is aware that the best way to assess pain is to:

• A. Take the blood pressure, pulse, and temperature
• B. Ask the client to rate his pain on a scale of 0-5
• C. Watch the client's facial expression
• D. Ask the client if he is in pain

Correct answer: B

Rationale: The best way to evaluate pain levels is to ask the client to rate his pain on a scale. This method provides a more standardized and quantifiable measure of pain compared to subjective observations like facial expressions (choice C) or direct questioning (choice D). Monitoring vital signs (choice A) can be part of pain assessment but is not as specific or reliable as asking the client to self-report pain intensity.
