PN ATI Capstone Proctored Comprehensive Assessment A
1. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?
- A. Increases blood pressure
- B. Prevents esophageal bleeding
- C. Decreases heart rate
- D. Reduces ammonia levels
Correct answer: D
Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.
2. A nurse is caring for a client who has a new diagnosis of oral candidiasis after taking tetracycline for 7 days. The nurse should recognize that candidiasis is a manifestation of which of the following adverse effects?
- A. Allergic response
- B. Superinfection
- C. Renal toxicity
- D. Hepatotoxicity
Correct answer: B
Rationale: Candidiasis is a type of superinfection that can occur when antibiotics, like tetracycline, disrupt the normal flora, allowing overgrowth of fungi. Option A, allergic response, is incorrect because candidiasis is not typically an allergic reaction. Option C, renal toxicity, and option D, hepatotoxicity, are incorrect as they refer to adverse effects on the kidneys and liver, respectively, which are not directly related to the development of candidiasis.
3. A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?
- A. Gentamicin
- B. Clindamycin
- C. Piperacillin
- D. Sulfamethoxazole-trimethoprim
Correct answer: C
Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.
4. A nurse is providing teaching to a newly licensed nurse about caring for a client who has a prescription for gemfibrozil. The nurse should instruct the newly licensed nurse to monitor which of the following laboratory tests?
- A. Platelet count
- B. Electrolyte levels
- C. Thyroid function
- D. Liver function
Correct answer: D
Rationale: The correct answer is D: Liver function. Gemfibrozil can lead to hepatotoxicity, making it crucial to monitor liver function tests. Monitoring platelet count (choice A) is not specifically indicated for gemfibrozil. Electrolyte levels (choice B) and thyroid function (choice C) are not directly affected by gemfibrozil, so they are not the primary laboratory tests to monitor in this case.
5. A client with gout is prescribed allopurinol. The nurse should instruct the client to discontinue taking the medication for which of the following adverse effects?
- A. Nausea
- B. Metallic taste
- C. Fever
- D. Drowsiness
Correct answer: C
Rationale: The correct answer is C: Fever. Fever can indicate a serious hypersensitivity reaction to allopurinol, known as allopurinol hypersensitivity syndrome, which can be severe and even life-threatening. Nausea and drowsiness are common side effects of allopurinol but not necessarily indications to discontinue the medication. Metallic taste is not typically associated with allopurinol use. Therefore, the nurse should emphasize to the client the importance of reporting any signs of fever promptly for further evaluation and management.
