1. How many drops per minute should a client weighing 182 pounds receive if a nurse mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min? The drip factor is 60 gtt/ml.
- A. 31 gtt/min.
- B. 62 gtt/min.
- C. 93 gtt/min.
- D. 124 gtt/min.
Correct answer: D
Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min × 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml × 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.
2. A client is admitted to the hospital with a diagnosis of pneumonia. Which laboratory test result should the nurse monitor to evaluate the client’s respiratory function?
- A. Arterial blood gases (ABGs)
- B. Complete blood count (CBC)
- C. Blood glucose levels
- D. Serum electrolyte levels
Correct answer: A
Rationale: Arterial blood gases (ABGs) are the most appropriate laboratory test to monitor respiratory function in a client with pneumonia. ABGs provide valuable information on oxygenation status, acid-base balance, and how well the lungs are exchanging gases. This information helps in assessing the effectiveness of ventilation and oxygenation, guiding treatment decisions, and evaluating the overall respiratory status of the client.
3. What information should the nurse offer a client who uses herbal therapies to supplement their diet and manage common ailments about the general use of herbal supplements?
- A. Most herbs are toxic or carcinogenic and should only be used when proven effective.
- B. There is no evidence that herbs are safe or effective compared to conventional supplements in maintaining health.
- C. Herbs should be obtained from manufacturers with a history of quality control for their supplements.
- D. Herbal therapies may mask the symptoms of serious diseases, requiring frequent medical evaluations during use.
Correct answer: C
Rationale: It is essential for clients using herbal therapies to obtain herbs from manufacturers with a history of quality control for their supplements. This recommendation is crucial because quality control processes help in maintaining the purity and effectiveness of the herbal supplements. Option A is incorrect as it provides a negative and inaccurate generalization about herbs. Option B is also incorrect as there is existing evidence on the safety and efficacy of certain herbal supplements. Option D is not the most relevant information to offer initially to a client seeking advice on the general use of herbal supplements.
4. The healthcare professional retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM 6 hours PRN for severe pain. How many mL should the healthcare professional administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth)
- A. 0.8 mL
- B. 0.75 mL
- C. 0.7 mL
- D. 0.9 mL
Correct answer: A
Rationale: To calculate the mL to administer, divide the ordered dose (3 mg) by the concentration (4 mg/mL). 3 mg ÷ 4 mg/mL = 0.75 mL. Rounding to the nearest tenth, the correct dose to administer is 0.8 mL.
5. The healthcare provider assesses a 2-year-old who is admitted for dehydration and finds that the peripheral IV rate by gravity has slowed, even though the venous access site is healthy. What should the healthcare provider do next?
- A. Apply a warm compress proximal to the site.
- B. Check for kinks in the tubing and raise the IV pole.
- C. Adjust the tape that stabilizes the needle.
- D. Flush with normal saline and recount the drop rate.
Correct answer: B
Rationale: In this scenario, the appropriate next step for the healthcare provider is to check for kinks in the tubing and raise the IV pole. These issues can commonly cause a slowed IV rate. Applying a warm compress (Choice A) may not address the underlying problem of kinked tubing or incorrect IV pole height. Adjusting the tape that stabilizes the needle (Choice C) is important for securement but is not the priority in this situation. Flushing with normal saline and recounting the drop rate (Choice D) should only be done after ruling out mechanical issues like kinks in the tubing.
