A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Assume you made a mistake and report out the same head circumference as before.

Incorrect Explanation: Assuming a mistake without taking proper action might not be the best approach.

Explanation: While it's good to consider the possibility of human error, healthcare professionals should prioritize accurate measurements and follow appropriate protocols when discrepancies arise.

B. Take Vital Signs.

Incorrect Explanation: Taking vital signs might not directly address the concern about the head circumference measurement.

Explanation: Vital signs (like heart rate, respiratory rate, blood pressure) are important indicators of a patient's overall health, but they may not directly address the issue of the head circumference measurement discrepancy.

C. Report to the MD/NP/PA in charge of the patient the head circumference that you obtained as well as the patient's current status. Expect that they will also re-measure.

Correct Explanation: This is the best next step.

Explanation: When there's a discrepancy in a critical measurement like head circumference, it's important to communicate this to the responsible healthcare provider (MD/NP/PA). They need to be aware of any changes in the patient's condition and measurements, and they will likely want to re-measure or reassess the situation themselves to ensure accuracy.

D. Move your measuring tape to above the mid-forehead, so that your number matches the findings from the week before.

Incorrect Explanation: Fudging measurements to match previous data is not a professional or ethical approach.

Explanation: Altering measurements to match previous values, especially without proper indication, is not a responsible practice in healthcare. It's essential to ensure accurate and honest documentation.

A. Elevated blood glucose is remarkable with Cushing's Triad:

Elevated blood glucose is not one of the components of Cushing's Triad. The triad focuses on cardiovascular and respiratory changes associated with increased intracranial pressure, not blood glucose levels.

B. Cushing's Triad includes a positive Macawen's sign:

Macawen's sign is not part of Cushing's Triad. Cushing's Triad is specifically related to the physiological responses seen in response to increased intracranial pressure and is not associated with Macawen's sign.

C. Cushing's Triad includes tachycardia, seizures and rapid respirations:

This option is not accurate. Cushing's Triad involves bradycardia (slow heart rate), irregular respirations, and a widening pulse pressure. Tachycardia (rapid heart rate) and seizures are not part of Cushing's Triad but might be indicative of other medical conditions or complications.

D. Bradycardia, irregular respirations and a widening pulse pressure.

Explanation: Cushing's Triad is a set of three clinical signs that are indicative of increased intracranial pressure (ICP) and are considered ominous as they suggest serious brain injury or pathology. The triad consists of:

Bradycardia: This refers to a slow heart rate. As intracranial pressure increases, it can lead to a decreased heart rate due to pressure on the brainstem, which is involved in regulating heart rate.

Irregular Respirations: Increased ICP can affect the brainstem's control over breathing, leading to irregular patterns of breathing, often known as Cheyne-Stokes respiration. This is characterized by periods of rapid breathing followed by apnea (temporary cessation of breathing).

Widening Pulse Pressure: Pulse pressure is the difference between systolic and diastolic blood pressure. An increase in ICP can cause an increase in systolic blood pressure and a decrease in diastolic blood pressure, leading to a widening pulse pressure.
