PN ATI Capstone Proctored Comprehensive Assessment A
1. 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.
2. A nurse is assessing a client who has a new prescription for chlorpromazine to treat schizophrenia. The client has a mask-like facial expression and is experiencing involuntary movements and tremors. Which of the following medications should the nurse anticipate administering?
- A. Amantadine
- B. Bupropion
- C. Phenelzine
- D. Hydroxyzine
Correct answer: A
Rationale: The correct answer is Amantadine. Amantadine is used to treat extrapyramidal symptoms, such as mask-like facial expressions, involuntary movements, and tremors, which are common side effects of antipsychotic medications like chlorpromazine. Bupropion is an antidepressant and not indicated for treating these symptoms. Phenelzine is a monoamine oxidase inhibitor used for depression and anxiety disorders, not for extrapyramidal symptoms. Hydroxyzine is an antihistamine used for anxiety and allergic conditions, not for the side effects described in the client.
3. A client with a seizure disorder has a new prescription for valproic acid. Which of the following laboratory values should the nurse plan to monitor? (Select all that apply)
- A. PTT
- B. Aspartate aminotransferase (AST)
- C. Alanine aminotransferase (ALT)
- D. All of the Above
Correct answer: D
Rationale: The correct answer is D, 'All of the Above.' Valproic acid can impact liver function and coagulation. Monitoring the Prothrombin Time (PTT), Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) is crucial. PTT is monitored to assess coagulation status, while AST and ALT are liver enzymes that indicate liver function. Monitoring these values helps detect any potential adverse effects of valproic acid on the liver and blood clotting. Choices A, B, and C are incorrect because each of these laboratory values plays a critical role in evaluating the client's response to valproic acid therapy and detecting associated complications.
4. A nurse is caring for a client who has a prescription for clopidogrel. The nurse should monitor the client for which of the following adverse effects?
- A. Insomnia
- B. Hypotension
- C. Bleeding
- D. Constipation
Correct answer: C
Rationale: The correct answer is C: Bleeding. Clopidogrel is an antiplatelet medication that works by preventing platelets from sticking together and forming clots. Therefore, one of the main adverse effects of clopidogrel is an increased risk of bleeding. Insomnia (Choice A), hypotension (Choice B), and constipation (Choice D) are not commonly associated with clopidogrel use. Monitoring for signs of bleeding, such as easy bruising, petechiae, or prolonged bleeding from minor cuts, is crucial when a client is taking clopidogrel.
5. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. The amount available is chlorothiazide oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth)
- A. 2.6 mL
- B. 2.63 mL
- C. 2.7 mL
- D. 2.2 mL
Correct answer: A
Rationale: To find the dose per administration, first convert the toddler's weight to kg: 28.6 lb ÷ 2.2 = 13 kg. Then calculate the total daily dose: 20 mg/kg × 13 kg = 260 mg/day. Since it is divided into two doses, each dose is 130 mg. The concentration of the oral suspension is 250 mg/5 mL = 50 mg/mL. Therefore, to find the volume needed per dose, divide the dose by the concentration: 130 mg ÷ 50 mg/mL = 2.6 mL per dose. Hence, the nurse should administer 2.6 mL per dose. Choices B, C, and D are incorrect as they do not accurately calculate the dosage of chlorothiazide needed per dose based on the toddler's weight and the concentration of the oral suspension.
