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:

The statement, "This medication will help regulate my mood and anxiety," is an accurate description of how antidepressants work. Antidepressants can help improve mood and reduce anxiety symptoms over time.

Choice B rationale:

This is the correct answer. Expecting immediate results from antidepressant medication is a misunderstanding. Antidepressants typically take several weeks to show their full therapeutic effects. Clients need to be informed about the delayed onset of action.

Choice C rationale:

The statement, "I may experience side effects such as nausea and drowsiness," is accurate. Antidepressants can indeed cause side effects, including gastrointestinal symptoms like nausea and drowsiness. This information is essential for the client to be aware of.

Choice D rationale:

This statement is correct. It is crucial to take antidepressant medication consistently as prescribed for the best therapeutic outcomes. Stopping or missing doses without consulting a healthcare provider can lead to treatment ineffectiveness.

A. Hypertension. B. Apical heart rate 72 beats/minute. C. Muscle weakness. D. Blood pressure 90/76 mm Hg.

Correct Answer is A

Explanation

Choice A rationale:

The contraindication for administering clonidine in this scenario is hypertension. Clonidine is an antihypertensive medication and can lower blood pressure. If the client has hypertension, giving clonidine could exacerbate the problem and cause further reduction in blood pressure, potentially leading to complications.

Choice B rationale:

An apical heart rate of 72 beats/minute is within the normal range for adults and is not a contraindication for administering clonidine. Clonidine primarily affects blood pressure and should be used cautiously in clients with hypertension, but it does not directly impact heart rate.

Choice C rationale:

Muscle weakness is not a contraindication for administering clonidine. Clonidine is not known to cause muscle weakness as a side effect. It primarily affects blood pressure regulation.

Choice D rationale:

A blood pressure of 90/76 mm Hg is lower than the normal range for blood pressure, but it is not a contraindication for administering clonidine. In fact, clonidine is often used to lower blood pressure in hypertensive individuals. However, in this scenario, the client's low blood pressure should be carefully monitored, and the nurse should consider adjusting the clonidine dose if necessary to avoid excessive hypotension.
