1. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
2. The healthcare provider has prescribed an influenza vaccine for a 74-year-old client before discharge. Which client condition would prompt the practical nurse to consult with the charge nurse rather than administer the vaccine?
- A. History of congestive heart failure
- B. History of an egg allergy
- C. History of pneumococcal vaccination
- D. History of end-stage renal disease
Correct answer: B
Rationale: The correct answer is B: History of an egg allergy. The influenza vaccine may contain a small amount of egg protein. According to the CDC, individuals with a severe allergy to any component of the vaccine, including egg protein, should not receive the influenza vaccine. Therefore, if the client has a history of an allergy to eggs, the practical nurse should not administer the vaccine and consult with the charge nurse for further guidance, as it is a contraindication. The other conditions listed do not require consultation before administering the influenza vaccine.
3. A client with diabetes mellitus type 2 is prescribed metformin. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of lactic acidosis to the healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals. Taking metformin with meals helps to minimize gastrointestinal side effects, which are common with this medication. Choice B, avoiding alcohol, is a good practice due to the increased risk of lactic acidosis when alcohol is consumed with metformin; however, it is not the priority teaching point in this scenario. Taking metformin on an empty stomach (Choice C) is incorrect because it can increase the risk of gastrointestinal side effects. Reporting signs of lactic acidosis (Choice D) is important, but it is more related to monitoring for adverse effects rather than a primary teaching point for administration.
4. A client with diabetes mellitus type 2 is prescribed linagliptin. Which instruction should the nurse include in the client's teaching plan?
- A. Report any signs of pancreatitis to the healthcare provider.
- B. Take this medication with meals.
- C. Avoid alcohol while taking this medication.
- D. Report any signs of heart failure to the healthcare provider.
Correct answer: A
Rationale: When a client is prescribed linagliptin, it is crucial to educate them to report any signs of pancreatitis to their healthcare provider. Linagliptin can lead to pancreatitis, making it essential for clients to be vigilant for symptoms such as severe abdominal pain, nausea, and vomiting. Timely reporting of these symptoms can aid in early intervention and management of pancreatitis.
5. A client with rheumatoid arthritis is prescribed adalimumab. What instruction should the nurse include in the client's teaching plan?
- A. Avoid live vaccines while taking this medication.
- B. Take this medication with food to decrease gastrointestinal upset.
- C. Report any signs of infection to the healthcare provider.
- D. Avoid sunlight exposure while taking this medication.
Correct answer: A
Rationale: The correct instruction for a client prescribed adalimumab, which is an immunosuppressant medication, is to avoid live vaccines. Adalimumab can weaken the immune system, making live vaccines potentially harmful. It is essential to educate the client on this to prevent complications and ensure the effectiveness of the treatment.
