1. To prevent aspiration in a client on mechanical ventilation receiving continuous enteral feedings through a nasogastric tube, which intervention is most important for the nurse to implement?
- A. Verify the feeding tube position with a daily chest x-ray
- B. Maintain head of bed elevated while enteral feeding is infusing
- C. Check feeding tube placement with air bolus prior to use
- D. Aspirate stomach contents every 4 hours to assess residuals
Correct answer: B
Rationale: The most important intervention to prevent aspiration in a client receiving continuous enteral feedings through a nasogastric tube while on mechanical ventilation is to maintain the head of the bed elevated while the feeding is infusing. This position helps reduce the risk of regurgitation and aspiration. Options A, C, and D are not as crucial as maintaining proper positioning to prevent aspiration. Verifying tube position with a daily chest x-ray is important but not the most crucial. Checking tube placement with an air bolus and aspirating stomach contents are important procedures but do not directly address the prevention of aspiration during enteral feedings.
2. A nurse is caring for an infant born with exstrophy of the bladder. What does the nurse determine is the greatest risk for this infant?
- A. Infection
- B. Dehydration
- C. Urinary retention
- D. Intestinal obstruction
Correct answer: A
Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The bladder mucosa and adjacent tissues being exposed increase the susceptibility to infections. Dehydration (Choice B) is not the primary concern in this condition. Urinary retention (Choice C) is less likely as exstrophy of the bladder usually presents with constant dribbling of urine. Intestinal obstruction (Choice D) is not directly related to exstrophy of the bladder.
3. Select the nursing interventions for a hospitalized client with mania who is exhibiting manipulative behavior. Select one intervention that does not apply.
- A. Communicate expected behaviors to the client
- B. Ensure that the client knows that he or she is not in charge of the nursing unit
- C. Assist the client in identifying ways of setting limits on personal behaviors
- D. Follow through about the consequences of behavior in a non-punitive manner
Correct answer: B
Rationale: The correct answer is B. Ensuring that the client knows they are not in charge of the nursing unit is not a helpful nursing intervention for managing manipulative behavior in a client with mania. Communicating expected behaviors, assisting with limit-setting, and following through on consequences in a non-punitive manner are more appropriate interventions to address manipulative behavior.
4. A client with a diagnosis of schizophrenia is prescribed clozapine. The nurse should monitor the client for which potential side effect?
- A. Agranulocytosis
- B. Dry mouth
- C. Weight gain
- D. Hypersalivation
Correct answer: A
Rationale: The correct answer is Agranulocytosis. Clozapine is known to potentially cause agranulocytosis, a serious condition characterized by a dangerously low white blood cell count. Monitoring white blood cell counts is crucial to detect this side effect early and prevent complications. Choices B, C, and D are incorrect because dry mouth, weight gain, and hypersalivation are not typically associated with clozapine use. While dry mouth can be a common side effect of some antipsychotic medications, it is not specifically linked to clozapine. Weight gain can occur with certain antipsychotics, but clozapine is more commonly associated with metabolic side effects. Hypersalivation is not a common side effect of clozapine.
5. A nurse receives a report about a client who has 0.9% sodium chloride infusing IV at 125 mL/hr. When the nurse performs the initial assessment, they note that the client has received only 80 mL over the last 2 hrs. Which of the following actions should the nurse take first?
- A. Check the IV tubing for obstruction
- B. Increase the infusion rate
- C. Administer a bolus of fluid
- D. Replace the IV catheter
Correct answer: A
Rationale: The correct first action for the nurse to take in this situation is to check the IV tubing for obstruction. By doing this, the nurse can assess if there is any blockage or kink in the tubing that is impeding the flow of the IV solution. This step is crucial as it helps in identifying the reason for the inadequate infusion rate. Increasing the infusion rate (Choice B) without first checking for obstructions can lead to potential complications if there is a blockage. Administering a bolus of fluid (Choice C) may not be appropriate without addressing the cause of the decreased infusion rate. Similarly, replacing the IV catheter (Choice D) is not the initial priority unless obstruction is ruled out and other troubleshooting measures have been taken.
