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. 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.
3. When bathing an uncircumcised boy older than 3 years, which action should the nurse take?
- A. Remind the child to clean his genital area.
- B. Defer perineal care due to the child's age.
- C. Retract the foreskin gently to cleanse the penis.
- D. Inquire about the reason for the child not being circumcised.
Correct answer: C
Rationale: The correct action when bathing an uncircumcised boy older than 3 years is to gently retract the foreskin to cleanse the penis. This is important to ensure proper hygiene and prevent the accumulation of bacteria that can lead to infections. It is not advisable to defer perineal care because of the child's age, as hygiene is crucial at any age. Asking the parents about the circumcision status may not be relevant during routine perineal care. Reminding the child to clean his genital area is not as effective as directly cleaning the area during bathing.
4. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. What respiratory rate should the nurse document?
- A. 14
- B. 16
- C. 17
- D. 28
Correct answer: B
Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.
5. What is the most important instruction for the nurse to provide a client with a new colostomy regarding stoma care?
- A. Cleanse the stoma with hydrogen peroxide and water.
- B. Apply a moisture barrier cream to the peristomal skin.
- C. Measure the stoma using a stoma guide.
- D. Use a dry gauze pad to clean the stoma.
Correct answer: C
Rationale: Measuring the stoma using a stoma guide (C) is crucial as it ensures that the appliance fits properly, which is essential for preventing skin irritation and leakage. Proper measurement helps in selecting the right size of the appliance, promoting comfort and optimal stoma care. In contrast, cleansing with hydrogen peroxide (A), applying a moisture barrier cream (B), and using a dry gauze pad (D) are important but not as critical as ensuring the correct fit of the stoma appliance.
