Introduction to Nursing 203 Quizlet Questions
Question 1 of 5
A pediatrician’s prescription reads “ampicillin sodium 125 mg IV every 6 hours.” The medication label reads “when reconstituted with 7.4 mL of bacteriostatic water, the final concentration is 1 g/7.4 mL.” The nurse prepares to draw up how many milliliters to administer 1 dose?
Correct Answer: D
Rationale: The correct answer is D (0.925 mL). To calculate the volume needed for 125 mg of ampicillin sodium at a concentration of 1 g/7.4 mL, we use the formula: Volume = (Desired dose * Volume of final concentration) / Concentration of final solution. Substituting the values gives Volume = (125 mg * 7.4 mL) / 1 g = 925 mg / 1000 mg = 0.925 mL. Therefore, the nurse should draw up 0.925 mL to administer one dose. Choice A (1.1 mL) is incorrect as it is not the correct calculation based on the given data. Choice B (0.54 mL) is incorrect as it does not match the calculated volume needed for the desired dose. Choice C (7.425 mL) is incorrect as it miscalculates the volume needed and does not align with the correct answer.
Question 2 of 5
When assessing a client's skin, the nurse notes a deep, irregular-shaped area of skin loss that extends below the dermis. What term would the nurse use when documenting this?
Correct Answer: A
Rationale: The correct term for a deep, irregular-shaped area of skin loss that extends below the dermis is an ulcer. Ulcers are characterized by tissue loss extending beyond the epidermis and dermis. A fissure is a linear crack in the skin, not a deep irregular shape. Keloid is an overgrowth of scar tissue, not skin loss. Erosion is superficial loss of the epidermis, not extending below the dermis. Therefore, the correct term in this scenario would be an ulcer.
Question 3 of 5
The nurse documents the client’s pulse as weak and thready. This pulse characteristic refers to:
Correct Answer: C
Rationale: Step-by-step rationale: 1. Weak and thready pulse refers to the volume of the pulse. 2. Pulse volume indicates the strength or force of the heartbeat. 3. A weak and thready pulse suggests a low volume of blood being ejected with each heartbeat. 4. This characteristic is important in assessing the client's perfusion status. Summary: A. Pulse rhythm: Refers to the regularity of the pulse pattern, not the strength. B. Pulse deficit: Refers to a difference between the apical and radial pulse rates, not the strength. C. Pulse volume: Correct answer. Reflects the strength or force of the heartbeat. D. Pulse rate: Refers to the number of heartbeats per minute, not the strength.
Question 4 of 5
The nurse is planning care for a client with a CVA. Which of the following measures planned by the nurse would be most effective in preventing skin breakdown?
Correct Answer: C
Rationale: The correct answer is C: Reposition every 2 hours. Repositioning every 2 hours helps to relieve pressure on bony prominences, reducing the risk of skin breakdown. This measure promotes circulation and tissue oxygenation. A: Placing the client in a wheelchair for extended periods can increase pressure on bony areas, leading to skin breakdown. B: Padding bony prominences may provide some protection but does not address the root cause of pressure. D: Massaging reddened areas can cause further damage to fragile skin and should be avoided.
Question 5 of 5
The client has developed liver failure. Which of the following laboratory values would Nurse Irene expect to have alterations?
Correct Answer: B
Rationale: The correct answer is B: Clotting factors. Liver failure can lead to impaired synthesis of clotting factors, resulting in abnormal coagulation tests. A: Blood urea nitrogen and creatinine are more related to kidney function. C: Creatinine kinase is an enzyme related to muscle breakdown. D: C-reactive protein is a marker of inflammation and infection, not specific to liver function. In liver failure, alterations in clotting factors are commonly seen due to the liver's role in synthesizing these proteins.
