Chapter 1 Introduction to Nursing Quizlet Questions
Question 1 of 5
What should the nurse instill first before administering intravenous medication through a medication lock?
Correct Answer: B
Rationale: The correct answer is B: Sterile normal saline. Before administering intravenous medication through a medication lock, the nurse should first instill sterile normal saline to ensure patency of the line and prevent clot formation. Normal saline is isotonic and compatible with most medications, helping to maintain hydration and prevent damage to the vein. Sterile bacteriostatic water (choice A) is not appropriate for this purpose. Sterile isopropyl alcohol (choice C) is used for skin preparation, not line maintenance. Sterile hydrogen peroxide (choice D) is too harsh and can cause tissue damage.
Question 2 of 5
You are preparing to hang fat emulsion and observes that fat globules are visible at the top of the solution. Which of the following actions should you take?
Correct Answer: B
Rationale: The correct answer is B because visible fat globules at the top of a fat emulsion solution indicate separation or instability. Obtaining a different bottle of solution ensures proper emulsion consistency for safe administration. Rolling the bottle gently (A) may not fully address the issue. Shaking vigorously (C) can further destabilize the emulsion. Running under warm water (D) could alter the emulsion's composition.
Question 3 of 5
A physician orders 1L of normal saline solution to infuse over 8 hours. The drop factor is 15 drops per 1 ml. Nurse Corazon prepares to set the flow rate at how many drops per minute?
Correct Answer: C
Rationale: To calculate the flow rate in drops per minute, we first find the total drops needed for 1L over 8 hours: 1L = 1000 ml 1000 ml * 15 drops/ml = 15000 drops 15000 drops / 8 hours = 1875 drops/hour 1875 drops / 60 minutes = 31.25 drops/minute, rounded to 31 drops/minute. Therefore, Choice C (31 gtts/minute) is correct. Choices A, B, and D are incorrect as they do not accurately calculate the correct flow rate based on the given drop factor and infusion parameters.
Question 4 of 5
A pediatric client with ventricular septal defect repair is placed on a maintenance dosage of digoxin. The dosage is 8 mcg/kg/day, and the client’s weight is 7.2 kg. The pediatrician prescribes the digoxin to be given twice daily. The nurse prepares how many mcg of digoxin to administer to the child at each dose?
Correct Answer: C
Rationale: To calculate the correct dosage, first, multiply the child's weight (7.2 kg) by the maintenance dosage (8 mcg/kg/day) to get the total daily dose: 7.2 kg x 8 mcg/kg/day = 57.6 mcg/day. Since the medication is given twice daily, divide the total daily dose by 2 to get the dosage for each administration: 57.6 mcg/day / 2 = 28.8 mcg. Therefore, the correct answer is C (28.8 mcg). Explanation for incorrect choices: A: 12.6 mcg - Incorrect, as it does not account for the correct calculation based on the child's weight and maintenance dosage. B: 21.4 mcg - Incorrect, as it is not the correct dosage obtained from the calculation. D: 32.2 mcg - Incorrect, as it is not the correct dosage based on the calculation provided.
Question 5 of 5
Which statement reflects appropriate documentation in the medical record of a hospitalized client?
Correct Answer: A
Rationale: The correct answer is A because it provides specific, objective information about a medical condition - a small pressure ulcer on the left leg. This type of documentation is crucial for accurate assessment, diagnosis, and treatment planning. Choice B is incorrect as it reflects subjective interpretation rather than a factual observation. Choice C is also incorrect as it lacks relevant medical information. Choice D is incorrect as it describes a physical symptom without a specific location or context. In medical documentation, clarity and precision are essential for communication among healthcare providers and ensuring quality patient care.
