A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?Reference Range:
Arterial Blood Gas (ABG)
pH [Adult/child: 7.35 to 7.45]
PaCO2 [Adult/child: 35 to 45 mm Hg)
HCO- [Adult/child: 21 to 28 mEq/L (21 to 28 mmol/L)] PaO2 [Adult/child: 80 to 100 mm Hg)

Increase rate of ventilation.

Decrease expiratory flow time.

Increase ventilator tidal volume.

Decrease expiratory pressure.

Answer and Explanation

The Correct Answer is A

Rationale

A. The client's pH is low (acidotic), and the PaCO2 is high (respiratory acidosis). Increasing the rate of ventilation (respiratory rate) can help to decrease PaCO2 by increasing alveolar ventilation, thereby helping to correct respiratory acidosis.

B. Expiratory flow time affects the time available for exhalation. While this may affect the overall mechanics of ventilation, it is not directly targeting the primary issue of elevated PaCO2 and acidosis.

C. Increasing tidal volume increases the volume of air delivered with each breath. This can improve ventilation efficiency but may not address the underlying problem of elevated PaCO2 unless it leads to increased minute ventilation.

D. Expiratory pressure is related to positive end-expiratory pressure (PEEP), which helps maintain alveolar recruitment and improve oxygenation. Decreasing expiratory pressure may not directly address the elevated PaCO2 and acidosis.

Correct Answer is ["A","C","E","F"]

Explanation

Rationale

A. Clenched fists can be a sign of pain in infants. Infants may reflexively clench their fists as a response to discomfort or pain. This behavior is commonly observed during painful procedures or when experiencing pain.

B. While fever can sometimes accompany pain due to inflammation or stress response, it is not typically a reliable indicator of pain in the absence of other signs. Therefore, fever alone is not a specific indicator of pain post-pyloromyotomy.

C. Restlessness or increased agitation can indicate pain in infants. They may squirm, move their arms and legs, or have difficulty settling down. Restlessness is a non-verbal cue that infants use to communicate discomfort or distress.

D. Peripheral pallor could indicate decreased peripheral perfusion, which might occur due to various factors post-operatively, but it is not a direct indicator of pain.

E. Increased respiratory rate can be associated with pain.

F. An increased pulse rate (tachycardia) is a physiological response to pain in infants. Pain activates the sympathetic nervous system, leading to an increased heart rate as the body prepares to respond to stress or discomfort.

Correct Answer is ["12.5"]

Explanation

To calculate the dosage of amoxicillin suspension to be administered every 8 hours, one must first determine the total daily dosage in milligrams. Since 1 gram equals 1000 milligrams, 1.5 grams is equivalent to 1500 milligrams. This total daily dosage needs to be divided into three doses, as it will be administered every 8 hours.

Therefore, each dose will be 1500 mg divided by 3, which equals 500 mg per dose. The medication bottle states that there are 200 mg of amoxicillin in every 5 mL of suspension. To find out how many mL correspond to a 500 mg dose, set up a proportion: 200 mg/5 mL = 500 mg/x mL. Solving for x gives x = (500 mg * 5 mL) / 200 mg, which equals 12.5 mL

Therefore, the nurse should administer 12.5 mL of the amoxicillin suspension every 8 hours.
