PN ATI Capstone Proctored Comprehensive Assessment A
1. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following indicates she is dehydrated?
- A. Urine specific gravity of 1.035
- B. Urine specific gravity of 444
- C. Urine specific gravity of 2000
- D. Urine specific gravity of 1111.1
Correct answer: A
Rationale: A urine specific gravity greater than 1.030 indicates dehydration. In this case, a urine specific gravity of 1.035 suggests concentrated urine, indicating dehydration. Choices B, C, and D have values that are not within the normal range for urine specific gravity and do not indicate dehydration. A urine specific gravity of 444, 2000, or 1111.1 are not physiologically possible values and are therefore incorrect.
2. A client with chronic kidney failure and an AV fistula for hemodialysis is prescribed epoetin alfa. Which of the following therapeutic effects should the nurse include in the teaching?
- A. Reduces blood pressure
- B. Inhibits clotting of fistula
- C. Promotes RBC production
- D. Stimulates growth of neutrophils
Correct answer: C
Rationale: The correct answer is C: Promotes RBC production. Epoetin alfa stimulates erythropoiesis (red blood cell production) to treat anemia associated with chronic kidney failure. This helps in increasing the hemoglobin levels and improving oxygen-carrying capacity. Choices A, B, and D are incorrect as epoetin alfa does not have direct effects on reducing blood pressure, inhibiting clotting of the fistula, or stimulating the growth of neutrophils.
3. A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct answer: A
Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.
4. A nurse is caring for a client who has been taking isoniazid and rifampin for 3 weeks for the treatment of active pulmonary tuberculosis (TB). The client reports his urine is an orange color. Which of the following statements should the nurse make?
- A. Stop taking the isoniazid for 3 days and the discoloration should go away.
- B. Rifampin can turn body fluids orange.
- C. I'll make an appointment for you to see the provider this afternoon.
- D. Isoniazid can cause bladder irritation.
Correct answer: B
Rationale: The correct answer is B: 'Rifampin can turn body fluids orange.' Rifampin is known to cause orange discoloration of body fluids, including urine. This side effect is harmless and does not indicate a need to stop the medication. Choice A is incorrect because stopping isoniazid will not resolve the orange urine discoloration caused by rifampin. Choice C is unnecessary at this point since the orange urine is a known side effect of rifampin and does not require an urgent provider visit. Choice D is incorrect because bladder irritation is not typically associated with isoniazid.
5. A nurse is reviewing the laboratory values for a client who is receiving a continuous IV heparin infusion and has an aPTT of 90 seconds. Which of the following actions should the nurse prepare to take?
- A. Administer vitamin K
- B. Reduce the infusion rate
- C. Give the client a low-dose aspirin
- D. Request an INR
Correct answer: B
Rationale: An aPTT of 90 seconds is elevated, indicating a risk of bleeding due to excessive anticoagulation. The appropriate action is to reduce the infusion rate of heparin to prevent further complications. Administering vitamin K is not indicated for an elevated aPTT due to heparin therapy. Giving the client a low-dose aspirin can further increase the risk of bleeding when combined with heparin. Requesting an INR is not necessary for monitoring heparin therapy; aPTT is the more specific test for assessing heparin's therapeutic effect. Therefore, the correct action for the nurse to prepare to take is to reduce the infusion rate of heparin.
