1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
2. A client who sustained a pellet gun injury with a resulting comminuted skull fracture is admitted overnight for observation. Which assessment finding obtained two hours after admission necessitates immediate intervention?
- A. The client complains of a throbbing headache rated 10 (on a scale of 1 to 10)
- B. The client repeatedly falls asleep while talking with the nurse
- C. The entry site has a slow trickle of bright red blood
- D. The entry site appears reddened and edematous
Correct answer: B
Rationale: In a client with a pellet gun injury and a comminuted skull fracture, repeatedly falling asleep while talking with the nurse is a concerning sign. It can indicate increased intracranial pressure or a deteriorating condition, requiring immediate intervention. The other options, such as a throbbing headache (choice A), slow trickle of bright red blood at the entry site (choice C), or reddened and edematous entry site (choice D), while important to monitor, do not directly indicate a need for immediate intervention as much as the client falling asleep repeatedly while talking does.
3. The nurse is providing care for a client with chronic obstructive pulmonary disease (COPD). Which intervention is most appropriate to include in the care plan?
- A. Instruct the client to use pursed-lip breathing
- B. Recommend a high-fat, low-carbohydrate diet
- C. Limit physical activity to prevent shortness of breath
- D. Encourage the client to drink large amounts of fluids
Correct answer: A
Rationale: The correct answer is A: Instruct the client to use pursed-lip breathing. Pursed-lip breathing helps improve ventilation and reduce shortness of breath in COPD clients. This technique involves inhaling slowly through the nose and exhaling through pursed lips. Choice B is incorrect because a high-fat, low-carbohydrate diet is not recommended for individuals with COPD as it can lead to weight gain and worsen respiratory function. Choice C is incorrect as limiting physical activity can lead to deconditioning and worsen COPD symptoms. Regular, moderate exercise is beneficial for individuals with COPD. Choice D is incorrect as excessive fluid intake can strain the heart in COPD clients. It is important to maintain adequate but not excessive fluid intake to prevent dehydration and maintain optimal lung function.
4. An older adult resident of a long-term care facility has a 5-year history of hypertension. The client has a headache and rates the pain 5 on a pain scale of 0 to 10. The client’s blood pressure is currently 142/89. Which interventions should the nurse implement? (Select all that apply)
- A. Administer the scheduled daily dose of lisinopril.
- B. Assess the client for postural hypotension.
- C. Notify the healthcare provider immediately.
- D. Provide a PRN dose of acetaminophen for the headache.
Correct answer: A
Rationale: In this scenario, the client's blood pressure of 142/89 is within an acceptable range for someone with a history of hypertension. The client's headache with a pain rating of 5 does not warrant an immediate notification to the healthcare provider. Administering the scheduled dose of lisinopril is appropriate to manage the client's hypertension. Assessing the client for postural hypotension is relevant due to the client's age and hypertension history. Providing a PRN dose of acetaminophen for the headache is not necessary at this point as the pain level is moderate and can be managed with other interventions.
5. The healthcare provider prescribed furosemide for a 4-year-old child with a ventricular septal defect. Which outcome indicates to the nurse that this pharmacological intervention was effective?
- A. Urine specific gravity changing from 1.021 to 1.031
- B. Daily weight decrease of 2 pounds (0.9 kg)
- C. Blood urea nitrogen (BUN) increasing from 8 to 12 mg/dl (2.9 to 4.3)
- D. Urinary output decreasing by 5 ml/hour
Correct answer: B
Rationale: The correct answer is B. A daily weight decrease of 2 pounds (0.9 kg) is the most appropriate outcome to indicate the effectiveness of furosemide in a child with a ventricular septal defect. Furosemide is a diuretic medication that helps reduce fluid retention. Therefore, a decrease in weight reflects a reduction in fluid volume, which is the desired effect of furosemide. Choices A, C, and D are incorrect because changes in urine specific gravity, blood urea nitrogen (BUN) levels, and urinary output do not directly reflect the effectiveness of furosemide in this context.
