1. The healthcare provider is evaluating the effectiveness of metaproterenol for how do you know it's been effective?
- A. Increased heart rate and blood pressure
- B. Decreased white blood cell count
- C. Decreased wheezing upon auscultation
- D. Decreased respiratory rate
Correct answer: C
Rationale: The effectiveness of metaproterenol, a bronchodilator, is assessed by a decrease in wheezing upon auscultation. Wheezing indicates airway constriction, and a reduction in wheezing signifies improved airflow and bronchodilation due to the medication's action. Therefore, choices A, B, and D are incorrect as they do not directly relate to the expected outcome of metaproterenol therapy.
2. A client with bipolar disorder is taking lithium. Which client assessment data would indicate a potential adverse effect of lithium therapy?
- A. Increased appetite
- B. Dry mouth and increased thirst
- C. Tremors and polyuria
- D. Constipation
Correct answer: B
Rationale: When assessing a client taking lithium, dry mouth and increased thirst are indicators of potential adverse effects. Lithium can lead to nephrogenic diabetes insipidus, causing polyuria and subsequent increased thirst due to impaired water reabsorption in the kidneys. Tremors can also be a sign of lithium toxicity. Monitoring and recognizing these symptoms are crucial in managing lithium therapy and preventing further complications.
3. A client with severe rheumatoid arthritis is prescribed methotrexate. The nurse should monitor the client for which potential adverse effect?
- A. Bone marrow suppression
- B. Increased risk of infection
- C. Liver toxicity
- D. Kidney stones
Correct answer: A
Rationale: The correct answer is A: Bone marrow suppression. Methotrexate, commonly used in rheumatoid arthritis, can lead to bone marrow suppression, reducing the production of blood cells and increasing the risk of infection. Monitoring for signs of anemia, leukopenia, and thrombocytopenia is crucial to detect bone marrow suppression early and prevent complications. Choices B, C, and D are incorrect because while methotrexate can increase the risk of infection, liver toxicity, and kidney issues, the primary concern and most significant adverse effect to monitor for is bone marrow suppression due to its impact on blood cell production.
4. 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.
5. During a home visit, a client with a history of angina reports frequent headaches. The client recently started a new prescription for diltiazem, a calcium channel blocker. What action should the nurse take?
- A. Explain the importance of obtaining a blood sample promptly to test for medication toxicity
- B. Consult with the healthcare provider regarding the necessity of an opioid analgesic for pain relief
- C. Recommend the client to discontinue the medication until contacting the healthcare provider
- D. Instruct the client on the use of acetaminophen every 4-6 hours as needed for headaches
Correct answer: D
Rationale: The correct action for the nurse to take is to instruct the client to use acetaminophen for headaches. Acetaminophen is a suitable and safer option for managing headaches associated with calcium channel blockers like diltiazem. It is essential to avoid medications that can interact negatively with diltiazem, such as opioid analgesics. Discontinuing the medication abruptly without consulting the healthcare provider is not recommended. Monitoring for medication toxicity through blood samples is not typically indicated for managing headaches in this scenario.
