1. A client with streptococcal pneumonia is receiving penicillin G by intermittent IV bolus. 10 minutes into the infusion of the third dose, the client reports itching at the IV site, dizziness, and shortness of breath. What should the nurse do first?
- A. Stop the infusion.
- B. Call the provider.
- C. Elevate the head of the bed.
- D. Auscultate breath sounds.
Correct answer: A
Rationale: In this scenario, the client is exhibiting signs of anaphylaxis, a severe allergic reaction. The priority action for the nurse is to stop the infusion immediately to prevent further administration of the allergen and worsening symptoms. Once the infusion is stopped, the nurse can then proceed with additional interventions, such as calling the provider, assessing the client's respiratory status, and providing appropriate care as needed.
2. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
3. A client has a new prescription for Clozapine. Which of the following statements should the nurse include in the teaching?
- A. You should have a high-carbohydrate snack between meals and at bedtime.
- B. You are likely to develop hand tremors if you take this medication for a long period of time.
- C. You may experience temporary numbness of your mouth after each dose.
- D. You should have your white blood cell count monitored every week.
Correct answer: D
Rationale: Clozapine carries a risk for fatal agranulocytosis. To monitor for this serious adverse effect, it is crucial to check the client's white blood cell count weekly while they are on clozapine therapy.
4. Before administering lithium to a client with bipolar disorder who has been taking the medication for 1 year, the nurse should check to see that which of the following tests has been completed?
- A. Thyroid hormone assay
- B. Liver function tests
- C. Erythrocyte sedimentation rate
- D. Brain natriuretic peptide
Correct answer: A
Rationale: The correct answer is to check the thyroid hormone assay. Long-term lithium use can result in thyroid dysfunction, making it crucial to monitor the client's thyroid function regularly to detect any abnormalities early and prevent potential complications. Liver function tests (choice B) are not specifically associated with lithium therapy. Erythrocyte sedimentation rate (choice C) is a nonspecific test for inflammation and not directly related to lithium therapy. Brain natriuretic peptide (choice D) is a test used to diagnose heart failure and is not relevant to monitoring lithium therapy.
5. A healthcare professional is preparing to administer Haloperidol 2 mg PO every 12 hr. The available dosage is haloperidol 1 mg/tablet. How many tablets should the healthcare professional administer?
- A. 1 tablet
- B. 2 tablets
- C. 3 tablets
- D. 4 tablets
Correct answer: B
Rationale: To determine the number of tablets needed, divide the desired dose by the dose per tablet. In this case, (2 mg / 1 mg/tablet) = 2 tablets required to administer the prescribed dose of Haloperidol.
