A nurse is assessing a school-age child who has moderate dehydration due to diarrhea and vomiting. Which of the following manifestations should the nurse expect?
Decreased respirations
Polyuria
Bradycardia
Orthostatic hypotension
The Correct Answer is D
A. Decreased respirations: Moderate dehydration typically does not cause respiratory depression. Respiratory changes are more commonly associated with severe acid-base imbalances or advanced dehydration.
B. Polyuria: Dehydration leads to decreased fluid volume, which generally results in oliguria (reduced urine output) rather than polyuria. Increased urination is not an expected finding in moderate dehydration.
C. Bradycardia: Dehydration usually causes a compensatory increase in heart rate (tachycardia) to maintain cardiac output. Bradycardia is not typical unless there is a severe or underlying cardiac issue.
D. Orthostatic hypotension: Loss of fluid volume from diarrhea and vomiting can decrease circulating blood volume, leading to a drop in blood pressure upon standing. This is an expected cardiovascular manifestation of moderate dehydration in school-age children.

Correct Answer is ["A","B","D","E"]
Explanation
A. Expected outcome of the procedure: The provider must explain the anticipated results of the colon resection so the client can make an informed decision about proceeding with the surgery.
B. Potential complications: The client should be informed of the risks and possible adverse events associated with the procedure, which is essential for informed consent.
C. Cost of the procedure: Financial information is not required for informed consent. While helpful for planning, it is not part of the medical disclosure required by the provider.
D. Explanation of the procedure: A clear description of the surgical steps allows the client to understand what the procedure entails, which is a fundamental component of informed consent.
E. Possible alternative treatments: The client must be aware of other treatment options, including the choice of no treatment, to make an informed decision regarding surgery.
Correct Answer is []
Explanation
Rationale for correct choices:
- Opioid intoxication: The client exhibits classic signs of opioid overdose, including shallow respirations, bradypnea, bradycardia, hypotension, hypothermia, slurred speech, and constricted pupils. These findings, combined with a history of oxycodone use, indicate opioid intoxication requiring immediate intervention.
- Obtain a prescription for naloxone: Naloxone is an opioid antagonist that reverses the respiratory depression, sedation, and other life-threatening effects of opioid overdose. Timely administration can prevent respiratory failure and death.
- Prepare to initiate mechanical ventilation: The client’s respiratory rate is critically low (10/min) with oxygen saturation at 90%, indicating inadequate ventilation. Mechanical ventilation may be required to maintain oxygenation and prevent hypoxia while naloxone takes effect.
- Pupillary reaction: Monitoring pupillary constriction or dilation helps assess the client’s response to opioid reversal therapy and can indicate ongoing central nervous system depression or improvement.
- Respiratory rate: Continuous monitoring of respiratory rate is essential because hypoventilation is the most immediate life-threatening effect of opioid intoxication. Changes indicate whether interventions like naloxone or ventilation are effective.
Rationale for incorrect choices:
- Alcohol intoxication: Although the client has a history of alcohol use disorder, the current symptoms of miosis, hypoventilation, and hypotension are more consistent with opioid toxicity rather than acute alcohol intoxication.
- Opioid withdrawal: Withdrawal presents with agitation, tachypnea, hypertension, dilated pupils, diaphoresis, and GI upset. This client’s bradycardia, hypotension, and hypoventilation indicate intoxication, not withdrawal.
- Stimulant intoxication: Stimulant overdose typically presents with hypertension, tachycardia, hyperthermia, and agitation. The client’s hypotension, bradycardia, and CNS depression are inconsistent with stimulant use.
- Anticipate administering clonidine: Clonidine is used for opioid withdrawal management, not acute intoxication. Administering it in this scenario would not address the life-threatening hypoventilation or CNS depression.
- Collect a blood sample for ethanol level: While it may be helpful for history, ethanol testing does not address the immediate life-threatening opioid overdose and is not a priority intervention.
- Obtain prescription for restraints: There is no indication for restraints. The client’s symptoms are due to CNS depression, and restraints would not improve their condition and could worsen injury risk.
- Hyperreflexia: This is a sign of opioid withdrawal or CNS stimulant activity, not opioid intoxication. The client’s deep tendon reflexes are decreased, consistent with CNS depression.
- Cardiac arrhythmias: While arrhythmias can occur, there is no evidence in this assessment of dysrhythmias. Monitoring vital signs and oxygenation is more immediately critical.
