1. A 43-year-old female client who has had a thyroidectomy due to Grave's disease is prescribed a thyroid replacement hormone. Which signs and symptoms are associated with thyroid hormone toxicity and should be reported promptly to the healthcare provider?
- A. Tinnitus and dizziness
- B. Tachycardia and chest pain
- C. Dry skin and intolerance to cold
- D. Weight gain and increased appetite
Correct answer: B
Rationale: The correct answer is B: Tachycardia and chest pain. Signs and symptoms of thyroid hormone toxicity, especially in cases of excessive dosage, include tachycardia (rapid heart rate) and chest pain. These symptoms are consistent with hyperthyroidism, where the body is receiving an excessive amount of thyroid hormone. It is crucial to report these symptoms promptly to the healthcare provider to adjust the medication dosage and prevent potential complications. Choices A, C, and D are not indicative of thyroid hormone toxicity. Tinnitus and dizziness (Choice A) are not typical symptoms of thyroid hormone toxicity. Dry skin and intolerance to cold (Choice C) are more common in hypothyroidism, while weight gain and increased appetite (Choice D) are associated with hypothyroidism as well, not thyroid hormone toxicity.
2. When a client with hepatic encephalopathy is receiving lactulose, which parameter is essential to monitor for a response to the drug?
- A. Serum hepatic enzymes
- B. Fingerstick glucose
- C. Stool color and character
- D. Serum electrolytes and ammonia
Correct answer: D
Rationale: In hepatic encephalopathy, the goal of lactulose therapy is to reduce blood ammonia levels by promoting its excretion in the stool. Therefore, monitoring serum electrolytes and ammonia levels is crucial to assess the effectiveness of lactulose in lowering ammonia levels and improving the client's condition. Options A, B, and C are incorrect because serum hepatic enzymes, fingerstick glucose, and stool color/character are not directly related to monitoring the response to lactulose therapy in hepatic encephalopathy.
3. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.
4. A client taking long-term steroids also has ranitidine prescribed. The nurse provides which explanation as to why these drugs are given together?
- A. Ranitidine reduces the risk of ulcers associated with steroids.
- B. Ranitidine decreases the risk of infection associated with steroids.
- C. Ranitidine decreases blood sugar elevations associated with steroids.
- D. Ranitidine reduces sodium retention associated with steroid usage.
Correct answer: A
Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation. Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.
5. The healthcare professional is creating a class for older adults in the community. Which information about laxative use in older adults would be important to include?
- A. Laxatives are not effective in older adults
- B. All laxatives are exactly the same
- C. Over-the-counter laxatives are misused
- D. Laxatives can cause potassium retention
Correct answer: C
Rationale: It is important to include information about the misuse of over-the-counter laxatives in older adults as they often misuse these medications, which can lead to dependency and other health issues. Option A is incorrect as laxatives can be effective in older adults when used appropriately. Option B is incorrect because not all laxatives are the same, they have different mechanisms of action and side effects. Option D is incorrect because laxatives can actually cause electrolyte imbalances like potassium depletion rather than retention.
