1. What is the primary reason for applying sequential compression devices (SCDs) to a patient’s legs postoperatively?

• A. To prevent deep vein thrombosis (DVT)
• B. To promote wound healing
• C. To reduce postoperative pain
• D. To maintain body temperature

Correct answer: A

Rationale: The correct answer is A: To prevent deep vein thrombosis (DVT). Sequential compression devices (SCDs) are used postoperatively to prevent DVT by promoting blood circulation in the legs. This helps reduce the risk of blood clots forming in the deep veins of the legs. Choice B, to promote wound healing, is incorrect as SCDs are primarily used for circulatory purposes rather than wound healing. Choice C, to reduce postoperative pain, is incorrect as the primary purpose of SCDs is not pain management but rather prevention of DVT. Choice D, to maintain body temperature, is incorrect as SCDs are not designed for regulating body temperature but for preventing circulatory issues.

2. 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.

3. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

4. When caring for a patient with a fresh tracheostomy, what is the nurse’s first priority?

• A. Providing humidified oxygen
• B. Ensuring the tracheostomy ties are secure
• C. Suctioning the tracheostomy tube as needed
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The correct answer is B: Ensuring the tracheostomy ties are secure. This is the nurse's first priority because it is critical to prevent accidental decannulation, which could compromise the patient’s airway. Providing humidified oxygen, suctioning the tracheostomy tube, and monitoring for signs of infection are important aspects of care but ensuring the tracheostomy ties' security takes precedence to maintain the patient's airway.

5. During a blood transfusion, which sign or symptom should prompt the healthcare provider to immediately stop the transfusion?

• A. Slight increase in blood pressure
• B. Elevated temperature and chills
• C. Mild nausea
• D. Slight headache

Correct answer: B

Rationale: The correct answer is B: Elevated temperature and chills. These symptoms are indicative of a transfusion reaction, which can be severe and life-threatening. It is crucial to stop the transfusion immediately and notify the healthcare provider for further assessment and management. Elevated temperature and chills are classic signs of a transfusion reaction, specifically indicating a possible febrile non-hemolytic reaction. Choice A, a slight increase in blood pressure, is not typically a reason to stop a transfusion unless it is a significant sudden increase. Mild nausea (Choice C) and a slight headache (Choice D) are common side effects of blood transfusions and are not primary indicators of a transfusion reaction that require immediate cessation of the transfusion.
