Nursing Elites

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. An adult male with a 6 cm thoracic aneurysm is being prepared for surgery. The nurse reports to the healthcare provider that the client’s blood pressure is 220/112 mmHg, so an antihypertensive agent is added to the client’s IV infusion. Which finding warrants immediate intervention by the nurse?

• A. Reports a tearing, sharp pain between his shoulder blades
• B. Blood pressure reading of 200/100 mmHg 15 minutes later
• C. Rose-colored urine draining from the urinary catheter
• D. Sinus tachycardia with frequent premature ventricular beats (PVC)

Correct answer: A

Rationale: A tearing, sharp pain between the shoulder blades may indicate aortic dissection, a serious complication requiring immediate intervention. This symptom is highly concerning in a patient with a thoracic aneurysm. Choice B is not as urgent as the pain symptom described in choice A. Choice C could indicate hematuria but is not as critical as the potential aortic dissection in choice A. Choice D, sinus tachycardia with PVCs, may be related to the patient's condition but is not as indicative of an immediate life-threatening situation as the tearing, sharp pain indicative of aortic dissection.

3. The nurse is evaluating a client who has had a mastectomy and is experiencing pain and swelling in the arm on the affected side. What action should the nurse take?

• A. Assess for signs of lymphedema
• B. Encourage the client to perform arm exercises
• C. Provide pain relief through medication
• D. Recommend wearing a compression sleeve

Correct answer: A

Rationale: Assessing for signs of lymphedema is crucial in this situation as it is a common complication following mastectomy. Lymphedema presents as swelling and pain in the affected arm due to compromised lymphatic drainage. By assessing for lymphedema, the nurse can identify the condition early and implement appropriate interventions such as compression sleeves, manual lymphatic drainage, and exercises. Encouraging arm exercises (Choice B) may exacerbate the symptoms if lymphedema is present. While providing pain relief through medication (Choice C) is important, assessing for the underlying cause of pain and swelling takes precedence. Recommending a compression sleeve (Choice D) may be suitable but should come after a thorough assessment for lymphedema to ensure the most effective management plan.

4. After successful resuscitation, a client is given propranolol and transferred to the Intensive Coronary Care Unit (ICCU). On admission, magnesium sulfate 4 grams IV in 250 ml D5W at one gram/hour. Which assessment findings require immediate intervention by the nurse?

• A. Dark amber urine draining via an indwelling catheter at a rate of 40 ml per hour
• B. Serum calcium of 9.0 mg/dl (2.2 mmol/L SI) and magnesium of 1.8 mg/dl or Eq/L (0.74 mmol/L SI)
• C. Sinus rhythm at 72 beats/minute and peripheral blood pressure of 99/62
• D. Respiratory rate of 10 breaths per minute

Correct answer: D

Rationale: The correct answer is D. A low respiratory rate of 10 breaths per minute is indicative of possible magnesium toxicity, which can be a serious condition requiring immediate intervention. It is a critical finding that needs prompt attention to prevent further complications. The other options are not as urgent: A - dark amber urine may indicate dehydration but does not require immediate intervention, B - serum calcium and magnesium levels are within normal limits, C - sinus rhythm and blood pressure values are also within normal range and do not require immediate action.

5. Which client’s vital signs indicate increased intracranial pressure (ICP) that the nurse should report to the healthcare provider?

• A. P 70, BP 120/60 mmHg; P 100, BP 90/60 mmHg; rapid respirations.
• B. P 55, BP 160/70 mmHg; P 50, BP 194/70 mmHg; irregular respirations.
• C. P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations.
• D. P 110, BP 130/70 mmHg; P 100, BP 110/70 mmHg; shallow respirations.

Correct answer: C

Rationale: Choice C is the correct answer. The vital signs presented (P 130, BP 190/90 mmHg; P 136, BP 200/100 mmHg; Kussmaul respirations) indicate increased intracranial pressure (ICP), which can be a serious condition requiring immediate medical attention. Kussmaul respirations are deep and labored breathing patterns associated with metabolic acidosis and can be a late sign of increased ICP. Choices A, B, and D do not demonstrate vital sign patterns consistent with increased ICP. Choice A shows variations in blood pressure and pulse rate but does not provide a clear indication of increased ICP. Choice B displays fluctuations in blood pressure and pulse rate with irregular respirations, but these vital signs do not specifically suggest increased ICP. Choice D presents relatively stable vital signs with shallow respirations, which do not align with the typical vital signs seen in increased ICP.
