Correct Answer is C

Explanation

a) Intravenous trimethoprim/sulfamethoxazole may still induce an adverse reaction, and withholding the oral medication is the more prudent initial action.

b) Administering the dose may worsen the client's condition, and addressing the symptoms requires notifying the provider first.

c) Withholding the treatment and promptly notifying the provider about the observed symptoms is the correct immediate response to potential adverse reactions.

d) Initiating probiotics and tapering off the medication may be considerations, but the urgent action is to withhold the medication and inform the provider.

A. Discuss possible opiate dependence with the client's provider. B. Note the effectiveness of the analgesia in the client's chart. C. Encourage the client to turn over, and cough and take deep breaths. D. Prepare to administer naloxone and provide respiratory support.

Correct Answer is D

Explanation

a) While discussing possible opiate dependence is important, the immediate concern is the client's respiratory depression and altered level of consciousness, which may require naloxone administration.

b) Noting the effectiveness of analgesia is relevant but does not address the current respiratory depression and lethargy observed in the client.

c) Encouraging the client to turn over and cough may not be effective in addressing severe respiratory depression, and immediate intervention is needed.

d) The client's symptoms, including drowsiness, lethargy, pinpoint pupils, and respiratory depression, are consistent with opioid overdose. Naloxone is the antidote for opioid toxicity and should be administered promptly.
