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?

Decrease expiratory flow time.

Decrease expiratory pressure.

Increase rate of ventilation.

Increase ventilator tidal volume.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Decreasing expiratory flow time is not the appropriate intervention in this case. The client's pH and PaCO2 levels suggest respiratory acidosis, which indicates inadequate ventilation. Increasing expiratory flow time might exacerbate the acidosis by reducing ventilation.

Choice C rationale:

Increasing the rate of ventilation (respiratory rate) is a potential intervention to improve the client's acid-base balance. However, it should be done cautiously and under medical supervision to avoid respiratory alkalosis. It is not the first-line intervention in this scenario.

Choice D rationale:

Increasing the ventilator tidal volume may help improve ventilation, but it should also be done under medical guidance to prevent barotrauma. It is not the initial intervention to address the client's respiratory acidosis.

Correct Answer is B

Explanation

Choice A rationale:

Granulating tissue in a foot ulcer is a positive sign of wound healing, but it may not be directly related to the effectiveness of pregabalin in treating diabetic peripheral neuropathy. The primary goal of pregabalin in this context is to reduce pain and neuropathic symptoms.

Choice B rationale:

A reduced level of pain is the most relevant indicator of the effectiveness of pregabalin in treating diabetic peripheral neuropathy. Pregabalin is an antiepileptic medication used to manage neuropathic pain. A decrease in pain indicates that the medication is effectively managing the client's symptoms.

Choice C rationale:

Improved visual acuity is not directly related to the effectiveness of pregabalin in treating diabetic peripheral neuropathy. Pregabalin primarily targets neuropathic pain and sensory symptoms, not visual function.

Choice D rationale:

A full volume of pedal pulses is a positive sign of adequate circulation in the lower extremities, but it may not be directly related to the effectiveness of pregabalin in treating neuropathy symptoms. The primary goal of pregabalin in this context is pain management.

A. Insert an indwelling catheter to empty the bladder and contract the fundus B. Check fundal consistency and continue to monitor the lochial ﬂow amount C. Return the client to bed and maintain bedrest until the lochial ﬂow slows D. Massage the fundus and avoid direct pressure on the cesarean incision

Correct Answer is D

Explanation

The correct answer and explanation is:

d) Massage the fundus and avoid direct pressure on the cesarean incision.

This is the best action to take for a client who experiences a sudden gush of vaginal blood and clots after a

cesarean section. Massaging the fundus helps to stimulate uterine contractions and reduce bleeding.

Avoiding direct pressure on the incision prevents pain and wound dehiscence.

a) Insert an indwelling catheter to empty the bladder and contract the fundus.

This is not the first action to take for a client who experiences a sudden gush of vaginal blood and clots after a cesarean section. Inserting an indwelling catheter requires a physician's order and may cause discomfort and infection. The client may already have a catheter in place after the surgery.

b) Check fundal consistency and continue to monitor the lochial ﬂow amount.

This is not enough to do for a client who experiences a sudden gush of vaginal blood and clots after a cesarean section. Checking fundal consistency and monitoring lochial ﬂow are important, but they do not address the cause of bleeding or prevent further blood loss.

c) Return the client to bed and maintain bedrest until the lochial ﬂow slows.

This is not appropriate for a client who experiences a sudden gush of vaginal blood and clots after a cesarean section. Returning the client to bed and maintaining bedrest may delay ambulation and increase the risk of thromboembolism. It also does not stop the bleeding or treat the underlying cause.
