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. Identify the placement of the stapes footplate into the bony labyrinth.

• A. Fenestra vestibuli
• B. Fenestra cochleae
• C. Tympanic membrane
• D. Round window

Correct answer: A

Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.

3. While changing the pressure ulcer dressing of a client who is immobile, the nurse notes that the boundary edges of the wound have increased. Before reporting this finding to the healthcare provider, the nurse should review which of the client’s serum laboratory values?

• A. Potassium
• B. Platelets
• C. Creatinine
• D. Albumin

Correct answer: D

Rationale: The correct answer is D: Albumin. Reviewing albumin levels is crucial in this situation because low albumin levels can impact wound healing and contribute to increased wound edges. Potassium (choice A) is not directly related to wound healing or wound edges. Platelets (choice B) are more related to blood clotting than wound healing. Creatinine (choice C) is related to kidney function, not specifically to wound healing or wound edges.

4. 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.

5. When preparing the client for a thoracentesis, which action is essential for the nurse to take?

• A. Encourage the client to cough during the procedure
• B. Ask the client to void prior to the procedure
• C. Have the client lie in the prone position
• D. Determine if chest x-rays have been completed

Correct answer: B

Rationale: The essential action for the nurse to take when preparing a client for a thoracentesis is to ask the client to void prior to the procedure. This step is crucial as it helps prevent discomfort and reduces the risk of accidental injury. Encouraging the client to cough during the procedure (Choice A) is inappropriate as it can affect the accuracy of the thoracentesis. Having the client lie in the prone position (Choice C) is incorrect; the procedure is typically performed with the client sitting upright or slightly leaning forward. While determining if chest x-rays have been completed (Choice D) is important, ensuring the client has emptied their bladder is more critical for their comfort and safety during the procedure.
