The nurse is caring for the client following a thoracentesis. (Select the 3 findings that require immediate follow-up.)
Decreased lung sounds
Heart rate 110/min and regular
Oxygen saturation of 95%
Subcutaneous emphysema
Trachea midline
Puncture site dry
Correct Answer : A,D
A. Decreased lung sounds
A decrease in lung sounds could indicate a pneumothorax, which is a potential complication of thoracentesis. It requires prompt evaluation.
B. Heart rate 110/min and regular
A heart rate of 110/min is within a normal range, and regular rhythm is generally acceptable post-thoracentesis. It may be related to pain or anxiety but is not an immediate concern.
C. Oxygen saturation of 95%
An oxygen saturation of 95% is within an acceptable range. While maintaining adequate oxygenation is important, this finding does not suggest an immediate complication.
D. Subcutaneous emphysema
Subcutaneous emphysema involves the presence of air in the subcutaneous tissues and can indicate a communication between the pleural space and subcutaneous tissues. This requires immediate attention.
E. Trachea midline
The trachea being midline is a normal finding and does not indicate an immediate problem post-thoracentesis.
F. Puncture site dry
A dry puncture site is expected after a thoracentesis. This finding is normal and indicates appropriate wound care. It is included in the list to ensure recognition of normal post-procedure findings.

Correct Answer is ["100"]
Explanation
Clindamycin is an antibiotic that can treat infections caused by staphylococci bacteria. It can be given by intermittent IV bolus, which means injecting the drug into a vein over a short period of time. To calculate the infusion rate for clindamycin, we need to use the formula:
Infusion rate (ml/hr) = Volume (ml) / Time (hr)
In this case, the volume is 50 ml and the time is 0.5 hr (30 min). Plugging these values into the formula, we get:
Infusion rate (ml/hr) = 50 ml / 0.5 hr
Infusion rate (ml/hr) = 100 ml/hr
Therefore, the nurse should set the IV pump to deliver 100 ml/hr of clindamycin.
Correct Answer is B
Explanation
A. An increase in the CMV rate:
Increasing the continuous mandatory volume (CMV) rate would provide more mandatory breaths, which may not address the patient's respiratory acidosis. It could potentially worsen the situation by causing respiratory alkalosis.
B. Change to SIMV (Synchronized Intermittent Mandatory Ventilation) MODE
The patient's arterial blood gas results indicate respiratory acidosis with an elevated PaCO2 (50 mmHg) and a low pH (7.30). The nurse would recommend changing to SIMV mode to allow for spontaneous breaths in addition to the set mandatory breaths. This change helps the patient to have more control over their respiratory efforts and may assist in lowering the PaCO2.
C. A decrease in the PaO2:
Decreasing the partial pressure of oxygen (PaO2) is not an appropriate response, especially when the patient is already on mechanical ventilation and has a moderate PaO2 level. The primary concern is the elevated PaCO2 and respiratory acidosis.
D. A decrease in the CMV rate:
Decreasing the CMV rate would reduce the number of mandatory breaths, potentially allowing the patient to hypoventilate further and retain more carbon dioxide. This is not the appropriate intervention for a patient with respiratory acidosis.
