1. A client is prescribed metoprolol. The nurse should monitor for which common side effect of this medication?
- A. Dizziness
- B. Fatigue
- C. Orthostatic hypotension
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Dizziness. Metoprolol, a beta-blocker, can lead to dizziness as a common side effect due to its mechanism of action in reducing heart rate and blood pressure. This effect can cause a sensation of lightheadedness or unsteadiness, particularly when standing up quickly. While fatigue, orthostatic hypotension, and headache are potential side effects of metoprolol, dizziness is commonly observed and should be closely monitored by the nurse to ensure patient safety.
2. 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.
3. When educating a client about the adverse effects of conjunctivitis, what is a serious condition that requires prompt attention?
- A. Contact lens irritation
- B. Decreased sex drive
- C. Brown spots on the skin
- D. Epigastric pain unrelieved by antacids
Correct answer: D
Rationale: Epigastric pain unrelieved by antacids is a concerning symptom that may indicate a more serious underlying condition such as a perforated ulcer. This symptom requires immediate medical attention to prevent further complications.
4. A client who takes metformin for diabetes mellitus type 2 is nothing by mouth (NPO) for surgery. What pre-op prescription should the practical nurse (PN) anticipate for this client's glucose management?
- A. NPO except for metformin and regular snacks
- B. NPO except for oral antidiabetic agent
- C. Novolin-N insulin subcutaneously twice daily
- D. Regular insulin subcutaneously per sliding scale
Correct answer: D
Rationale: When a client taking metformin for diabetes mellitus type 2 is NPO for surgery, it is crucial to manage their glucose levels effectively. The best approach in this situation is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications. Choices A and B are incorrect because metformin is typically held when a client is NPO, and oral antidiabetic agents may not provide sufficient glucose control. Choice C is incorrect as Novolin-N insulin given twice daily may not offer the flexibility needed for glucose management in a surgical setting where the client's intake is restricted.
5. The healthcare provider is discharging a patient with a new prescription for ranitidine (Zantac). Which information would be important to include in the discharge teaching?
- A. Thrombolytic thrombocytopenic purpura (TTP) may occur
- B. Aspirin should not be taken with this medication
- C. The patient may experience iron deficiency anemia
- D. The patient may experience restlessness
Correct answer: D
Rationale: The correct answer is D. It is important to include information that ranitidine may cause restlessness as a side effect in some patients. Educating the patient about possible side effects helps in early recognition and management, improving medication adherence and patient safety. Choices A, B, and C are incorrect because they do not pertain to common side effects or specific considerations related to ranitidine use.
