A client's IV fluid orders for 24 hour's are 1500 ml D5W followed by 1250 ml of NS. The IV tubing has a drop factor of 15 gtt/ml. To administer the required fluids the nurse should set the drip rate at;

Correct Answer: B

Rationale: To calculate the drip rate, we first need to find the total volume of IV fluid to be administered, which is 1500 ml + 1250 ml = 2750 ml. Then, we multiply the total volume by the drop factor (2750 ml * 15 gtt/ml = 41250 gtt). Finally, we divide the total number of drops by the time in minutes (24 hours * 60 min = 1440 min) to get the drip rate: 41250 gtt / 1440 min = 28.47 gtt/min, which rounds up to 29 gtt/min. Therefore, choice B is correct. Choices A, C, and D are incorrect because they do not reflect the accurate calculation based on the given parameters.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): A complete blood count (CBC) is used to identify abnormalities in red blood cells, white blood cells, and platelets. Hematocrit (HCT) and hemoglobin (Hb) levels are part of a CBC and indicate the oxygen-carrying capacity of the blood. Abnormally low HCT and Hb levels can signify conditions like anemia, which can impact a client's ability to undergo surgery due to potential complications related to oxygen delivery. Summary of Incorrect Choices: A: Potential hepatic dysfunction is not directly related to a CBC, and BUN/creatinine levels are markers for kidney function, not liver function. B: Low levels of urine constituents are not assessed in a CBC, which focuses on blood components. D: Electrolyte imbalance is not specifically tested in a CBC; it is usually evaluated through separate blood tests. Coagulation factors are not directly measured in a CBC.

Correct Answer: D

Rationale: The correct answer is D: 60 seconds. This is because the area must be cleaned for at least 60 seconds to effectively disinfect the skin and reduce the risk of infection during venipuncture. Cleaning for shorter durations (5, 10, or 30 seconds) may not be sufficient to achieve proper disinfection. Thoroughly cleaning the area for a full minute ensures that the alcohol has enough time to kill bacteria and pathogens on the skin, making it safer for the venipuncture procedure. Shorter cleaning times may leave pathogens behind, increasing the risk of contamination and infection.

Correct Answer: A

Rationale: The correct answer is A because collecting urine 24-48 hrs after the client has received nonradioactive B12 is essential for the Schilling test to evaluate vitamin B12 absorption. Urine is collected to measure the excretion of radioactive B12, which helps in diagnosing pernicious anemia or malabsorption issues. Incorrect choices: B: Collecting blood samples is not necessary for the Schilling test as it primarily involves urine collection. C: Allowing oral fluid consumption is important to prevent dehydration and is not contraindicated after receiving nonradioactive B12. D: Making the client lie down in the supine position is unnecessary for the Schilling test and may not affect the test results.

Correct Answer: C

Rationale: The correct answer is C because Nursing Outcomes Classification adds objectivity to judging a patient's progress by providing standardized criteria for assessing outcomes. This helps in evaluating the effectiveness of interventions and tracking improvements accurately. Other choices are incorrect: A is wrong because Nursing Outcomes Classification includes 7 domains but not necessarily for level 1; B is incorrect as it uses a 5-point Likert scale, not a 3-point scale; and D is inaccurate because Nursing Outcomes Classification guides the selection of interventions based on the identified outcomes, not allowing complete freedom in choosing interventions.
