1. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?
- A. 31 gtt/min.
- B. 62 gtt/min.
- C. 93 gtt/min.
- D. 124 gtt/min.
Correct answer: D
Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
2. When taking a history of a 3-year-old with neuroblastoma, what comment by the parents requires follow-up and is consistent with the diagnosis?
- A. The child has been listless and has lost weight.
- B. The urine is dark yellow and in small amounts.
- C. Clothes are becoming tighter across her abdomen.
- D. We notice muscle weakness and some unsteadiness.
Correct answer: C
Rationale: The correct answer is C. Clothes becoming tighter across the abdomen is indicative of an abdominal mass, a common presentation in neuroblastoma. This symptom should be followed up on further as it aligns with the diagnosis. Choices A, B, and D are less specific to neuroblastoma. Weight loss and listlessness (Choice A) can be nonspecific symptoms, while dark yellow urine in small amounts (Choice B) may suggest dehydration or other conditions. Muscle weakness and unsteadiness (Choice D) could point towards various neurological or muscular issues but are not as directly related to neuroblastoma as the symptom described in Choice C.
3. The healthcare provider is caring for a client with tuberculosis (TB). Which type of isolation precautions should the healthcare provider implement?
- A. Droplet precautions
- B. Airborne precautions
- C. Contact precautions
- D. Standard precautions
Correct answer: B
Rationale: When caring for a client with tuberculosis (TB), airborne precautions should be implemented. Tuberculosis is spread through the air via droplet nuclei, requiring the use of airborne precautions to prevent the transmission of the infection. Droplet precautions are used for diseases spread by large respiratory droplets, such as influenza or pertussis. Contact precautions are used for diseases that spread through direct contact, such as MRSA. Standard precautions are used for all clients to prevent the transmission of infections from blood, body fluids, non-intact skin, and mucous membranes.
4. A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?
- A. “This device will keep me from developing skin sores.â€
- B. “This device will keep the blood circulating in my leg.â€
- C. “This device will prevent my leg muscles from weakening.â€
- D. “This device will maintain the health of my joints.â€
Correct answer: B
Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.
5. When performing nasotracheal suctioning for a client with a respiratory infection, what technique should the nurse use?
- A. Apply intermittent suction when withdrawing the catheter
- B. Suction continuously while inserting the catheter
- C. Suction intermittently while inserting the catheter
- D. Use a Yankauer suction device
Correct answer: A
Rationale: When performing nasotracheal suctioning for a client with a respiratory infection, the nurse should apply intermittent suction when withdrawing the catheter. This technique helps minimize mucosal damage and is considered best practice. Choice B, suctioning continuously while inserting the catheter, is incorrect as continuous suctioning can cause trauma to the airway. Choice C, suctioning intermittently while inserting the catheter, is also incorrect as it can increase the risk of hypoxia and mucosal damage. Choice D, using a Yankauer suction device, is not appropriate for nasotracheal suctioning as it is typically used for oral suctioning. Therefore, the correct technique is to apply intermittent suction when withdrawing the catheter to ensure effective and safe suctioning.
