1. In the emergency department, a child is admitted for accidental ingestion of a poison. The practical nurse (PN) should know that inducing vomiting is recommended for which child?
- A. An 8-month-old who ingested four to six ibuprofen tablets
- B. A 3-year-old who drank an unknown amount of charcoal lighter fluid
- C. A 16-month-old who ingested 2 ounces of acetaminophen elixir
- D. A 2-year-old who ate a handful of automatic dishwasher detergent
Correct answer: C
Rationale: Inducing emesis is recommended for the child who ingested a large dose of acetaminophen elixir because this medication is hepatotoxic. Acetaminophen overdose can lead to severe liver damage, and prompt removal from the stomach can help reduce absorption and potential harm.
2. A client with chronic kidney disease is prescribed ferric citrate. The nurse should monitor for which potential side effect?
- A. Constipation
- B. Diarrhea
- C. Nausea
- D. Hyperphosphatemia
Correct answer: A
Rationale: When a client with chronic kidney disease is prescribed ferric citrate, the nurse should monitor for constipation as a potential side effect. Ferric citrate can lead to constipation due to its effects on the gastrointestinal system, causing a decrease in bowel movements. It is essential for the nurse to assess and manage constipation promptly to prevent complications and ensure the client's comfort and well-being. Monitoring bowel movements, providing adequate hydration, and recommending dietary interventions can help alleviate constipation in clients taking ferric citrate. Diarrhea, nausea, and hyperphosphatemia are not typically associated with the use of ferric citrate in clients with chronic kidney disease.
3. A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
- A. Advise the client that the effects of the medication have worn off
- B. Explain that the medication is not given to relieve pain
- C. Check for the correct placement of the patch on the client
- D. Offer to apply a new transdermal patch to address the pain
Correct answer: B
Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario. Offering to apply a new patch would not address the client's pain as scopolamine is not meant for pain relief. Advising the client that the effects have worn off is inaccurate because the medication is not used for pain management.
4. A healthy 68-year-old client asks the practical nurse (PN) whether they should take the pneumococcal vaccine. Which statement should the PN offer to the client that provides the most accurate information about this vaccine?
- A. The vaccine is given annually before the flu season to those older than 50 years.
- B. The immunization is recommended for children younger than 2 years old and all adults 65 years or older.
- C. The vaccine is for all ages and is given primarily to those traveling overseas to areas of infection.
- D. The vaccine will prevent the occurrence of pneumococcal pneumonia for up to 5 years.
Correct answer: B
Rationale: The correct answer is B because it is usually recommended that children younger than 2 years old and adults 65 years or older get vaccinated against pneumococcal disease. This is because these age groups are more susceptible to severe complications from the infection. While the vaccine may be recommended for certain individuals with specific medical conditions at any age, the primary target groups are as mentioned in option B. Option A is incorrect as the pneumococcal vaccine is not given annually like the flu vaccine. Option C is incorrect because the vaccine is not primarily for travelers but for certain age groups and individuals with medical conditions at risk. Option D is incorrect as the vaccine's duration of protection can vary, and it is not guaranteed to prevent pneumococcal pneumonia for up to 5 years.
5. A client with a diagnosis of schizophrenia is prescribed olanzapine. The nurse should monitor for which potential side effect?
- A. Weight gain
- B. Insomnia
- C. Dry mouth
- D. Headache
Correct answer: A
Rationale: When a client with schizophrenia is prescribed olanzapine, the nurse should monitor for weight gain as a potential side effect. Olanzapine is known to cause metabolic changes that can lead to weight gain, making it crucial for the nurse to closely monitor the client's weight during treatment. This side effect is significant as it can impact the client's overall health and well-being, so early detection and intervention are essential to manage it effectively.
