PN ATI Capstone Proctored Comprehensive Assessment A
1. A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)
- A. 0.5 mL
- B. 0.005 mL
- C. 0.05 mL
- D. 5 mL
Correct answer: A
Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.
2. A healthcare professional is reviewing the laboratory results for a client who has a prescription for filgrastim. The healthcare professional should recognize that an increase in which of the following values indicates a therapeutic effect of this medication?
- A. Erythrocyte count
- B. Neutrophil count
- C. Lymphocyte count
- D. Thrombocyte count
Correct answer: B
Rationale: Filgrastim is a medication used to stimulate the production of neutrophils in patients with neutropenia. Neutrophils are a type of white blood cell that plays a crucial role in fighting off infections. Therefore, an increase in neutrophil count would indicate a therapeutic effect of filgrastim. The other options, such as erythrocyte count (red blood cells), lymphocyte count, and thrombocyte count (platelets), are not directly affected by filgrastim and would not indicate a therapeutic effect of this medication.
3. A client with a severe urinary tract infection (UTI) asks why both ciprofloxacin and phenazopyridine are needed. Which of the following responses should the nurse make?
- A. Phenazopyridine decreases adverse effects of ciprofloxacin.
- B. Combining phenazopyridine with ciprofloxacin shortens the course of therapy.
- C. The use of phenazopyridine allows for a lower dosage of ciprofloxacin.
- D. Ciprofloxacin treats the infection, and phenazopyridine treats pain.
Correct answer: D
Rationale: Ciprofloxacin is an antibiotic that treats the infection, while phenazopyridine is a urinary analgesic that relieves pain. Choice A is incorrect because phenazopyridine does not decrease adverse effects of ciprofloxacin; it primarily addresses pain. Choice B is incorrect because combining phenazopyridine with ciprofloxacin does not shorten the course of therapy; they serve different purposes. Choice C is incorrect because the use of phenazopyridine does not allow for a lower dosage of ciprofloxacin; they have independent roles in UTI management.
4. A nurse is caring for an older adult client who has a new prescription for amitriptyline to treat depression. Which of the following diagnostic tests should the nurse plan to perform prior to starting the client on this medication?
- A. Hearing examination
- B. Glucose tolerance test
- C. Electrocardiogram
- D. Pulmonary function tests
Correct answer: C
Rationale: The correct answer is C: Electrocardiogram. Amitriptyline can cause cardiac arrhythmias, so an electrocardiogram is necessary before starting treatment. A hearing examination (choice A) is not required before initiating amitriptyline. A glucose tolerance test (choice B) is not indicated for starting this medication. Pulmonary function tests (choice D) are not necessary before initiating amitriptyline for depression.
5. 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.
