1. Twenty-four hours after starting to take oral penicillin for strep throat, a client calls the nurse to report the onset of a rash on the chest. What action should the nurse implement?
- A. Instruct the client to discontinue the penicillin immediately
- B. Instruct the client regarding the use of topical analgesic cream PRN
- C. Question the client about any other related symptoms
- D. Reinforce the need to take all doses of the penicillin
Correct answer: A
Rationale: In this scenario, the client has developed a rash after starting oral penicillin, which can indicate an allergic reaction. It is crucial for the nurse to instruct the client to discontinue the penicillin immediately. Continuing the medication can potentially lead to severe allergic reactions. Instructing about topical analgesic cream or questioning about other related symptoms may delay appropriate action in case of a severe allergic reaction. Reinforcing the need to complete all doses is not appropriate when an allergic reaction is suspected, as safety takes precedence over completing the antibiotic course.
2. Escitalopram is prescribed for a 16-year-old adolescent client who is clinically depressed. Five days later, the parent tells the practical nurse (PN) that the drug is not working because their child is not feeling any better. Which explanation should the PN provide?
- A. It takes 1 to 4 weeks for antidepressant medications to become effective.
- B. The dosage may need to be increased; I will contact your health care provider.
- C. Depression is difficult to treat with drugs alone. Therapy sessions would enhance their effectiveness.
- D. Based on your child's response to this drug, the health care provider is reviewing your medication regimen.
Correct answer: A
Rationale: Antidepressant medications typically require 1 to 4 weeks to reach their full therapeutic effect. It is crucial to educate the family that during the initial week of treatment, the child may experience heightened anxiety. Therefore, it is important to wait for the medication to take its full course before assessing its effectiveness.
3. A client with rheumatoid arthritis is prescribed sulfasalazine. Which instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid sunlight while taking this medication.
- C. Report any signs of infection to the healthcare provider.
- D. Take this medication on an empty stomach.
Correct answer: A
Rationale: The correct instruction to include in the client's teaching plan regarding sulfasalazine is to take the medication with meals. Taking sulfasalazine with food helps to minimize gastrointestinal upset, which is a common side effect of the medication. Choice B is incorrect because avoiding sunlight is not specifically related to sulfasalazine. Choice C is important but not directly related to the administration of sulfasalazine. Choice D is incorrect because sulfasalazine should be taken with meals to reduce gastrointestinal side effects.
4. A client with type 2 diabetes mellitus is prescribed semaglutide. The nurse should monitor for which potential adverse effect?
- A. Nausea
- B. Hypoglycemia
- C. Hyperglycemia
- D. Pancreatitis
Correct answer: A
Rationale: The correct answer is A: Nausea. Semaglutide, a medication used to treat type 2 diabetes, is known to cause nausea as a potential adverse effect. It is important for the nurse to monitor the client for gastrointestinal symptoms, including nausea, after initiating treatment with semaglutide. While hypoglycemia and hyperglycemia are common concerns in diabetes management, they are not the primary adverse effects associated with semaglutide. Pancreatitis is a serious but rare adverse effect of GLP-1 receptor agonists like semaglutide, which should also be monitored for, but nausea is a more common and immediate concern.
5. A client with a history of myocardial infarction is prescribed atorvastatin. The nurse should monitor the client for which potential adverse effect?
- A. Liver damage
- B. Kidney damage
- C. Muscle pain
- D. Increased appetite
Correct answer: C
Rationale: The correct answer is C: Muscle pain. Atorvastatin can cause muscle pain, which may indicate rhabdomyolysis, a serious adverse effect. Rhabdomyolysis is a condition where muscle breakdown releases a protein (myoglobin) into the bloodstream, potentially leading to kidney damage. Liver damage (choice A) is a less common side effect of atorvastatin compared to muscle pain. Kidney damage (choice B) is not a direct adverse effect of atorvastatin but can occur indirectly if rhabdomyolysis is severe. Increased appetite (choice D) is not a known adverse effect of atorvastatin.
