Nursing Elites

1. Which of the following is MOST LIKELY to increase the risk of a medication error?

• A. Not using abbreviations for medications
• B. Errors in the calculation of medication dosages
• C. Barcoding medication orders
• D. Utilizing unit dose dispensers

Correct answer: B

Rationale: Errors in the calculation of medication dosages are a significant risk factor for medication errors. When dosage calculations are incorrect, it can lead to administering the wrong amount of medication, posing serious harm to the patient. Avoiding abbreviations for medications, barcoding medication orders, and utilizing unit dose dispensers are all strategies aimed at reducing medication errors by enhancing accuracy and safety. Therefore, choices A, C, and D are incorrect as they are practices that help decrease, rather than increase, the risk of medication errors.

2. A client post-lobectomy is placed on mechanical ventilation. The nurse notices the client is fighting the ventilator. What should the nurse do first?

• A. Increase the sedation as prescribed.
• B. Manually ventilate the client using an ambu bag.
• C. Check the ventilator settings and alarms.
• D. Suction the client’s airway.

Correct answer: C

Rationale: The correct first action for the nurse to take when a client is fighting the ventilator is to check the ventilator settings and alarms. This step is crucial to ensure that the ventilator is functioning correctly and providing the necessary support to the client. Increasing sedation (Choice A) should only be considered after confirming that the ventilator settings are appropriate. While manually ventilating the client (Choice B) may be required in some cases, it is not the initial action to take. Suctioning the client's airway (Choice D) is not the priority in this situation, where the primary concern is addressing the client's struggle with the ventilator.

3. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

4. What is the primary function of hemoglobin in red blood cells?

• A. To transport oxygen from the lungs to body tissues
• B. To protect the body from infections
• C. To help in blood clotting
• D. To regulate body temperature

Correct answer: A

Rationale: The primary function of hemoglobin in red blood cells is to transport oxygen from the lungs to body tissues and return carbon dioxide from the tissues to the lungs. Hemoglobin binds to oxygen in the lungs and releases it in the body's tissues. Choice B is incorrect because hemoglobin is not involved in protecting the body from infections. Choice C is incorrect because blood clotting is mainly facilitated by platelets and clotting factors, not hemoglobin. Choice D is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not by hemoglobin.

5. A 50-year-old female is in the hospital with peripheral artery disease. In the nursing care plan, the nurse lists the following nursing diagnosis: Ineffective tissue perfusion: peripheral related to venous stasis. Which of the following would not be an appropriate nursing action to list in the implementation of this diagnosis?

• A. Keep the client's extremities cold
• B. Check for strength and symmetry of peripheral pulses
• C. Keep the client's legs elevated
• D. Monitor for any constrictions, such as clothes or covers that are too tight around the legs

Correct answer: A

Rationale: Keeping the client’s extremities cold would worsen perfusion issues and is not recommended. In peripheral artery disease, maintaining warmth is crucial to promote vasodilation and improve blood flow. Checking peripheral pulses for strength and symmetry, keeping the client's legs elevated to reduce venous stasis, and monitoring for constrictions that may impair circulation are appropriate nursing actions to enhance tissue perfusion in this case. Thus, option A is incorrect as it would hinder perfusion in the affected extremities.
