ATI RN Custom Exams Set 3
1. What is the primary goal of care for a client diagnosed with sickle cell anemia?
- A. The client will contact the healthcare provider if feeling unwell.
- B. The client will adhere to the medical regimen.
- C. The client will live as normal a life as possible.
- D. The client will demonstrate understanding of treatments.
Correct answer: C
Rationale: The primary goal of care for a client diagnosed with sickle cell anemia is to help them live as normal a life as possible. This involves managing symptoms, preventing crises, and promoting overall well-being. While options A, B, and D are important aspects of care, the ultimate goal is to enhance the client's quality of life and support them in leading a fulfilling and active lifestyle despite their condition.
2. What ECG changes are expected in a patient with hypokalemia?
- A. Flattened T waves
- B. Prominent U waves
- C. Widened QRS complexes
- D. Tall T waves
Correct answer: A
Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.
3. Which patient statement to the nurse indicates a need for additional instruction about taking oral ferrous sulfate?
- A. I will call my health care provider if my stools turn black.
- B. I will take a stool softener if I feel constipated occasionally.
- C. I should take the iron with orange juice about an hour before eating.
- D. I should increase my fluid and fiber intake while I am taking iron tablets.
Correct answer: A
Rationale: It is normal for the stools to appear black when a patient is taking iron, and the patient should not call the health care provider about this.
4. A nurse is initiating continuous enteral feedings for a client who has a new gastrostomy tube. Which of the following actions should the nurse take?
- A. Measure the client’s gastric residual every 12 hr.
- B. Obtain the client’s electrolyte levels every 4 hr.
- C. Keep the client’s head elevated at 15* during feedings.
- D. Flush the client’s tube with 30 mL of water every 4 hr.
Correct answer: D
Rationale: Flushing the client's tube with 30 mL of water every 4 hours helps maintain tube patency and prevent blockages.
5. What is pharmacodynamics?
- A. The medical reference summarizing standards of drug purity, strength, and directions for synthesis
- B. The drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions
- C. The maximum response that a drug can produce
- D. Movements of the drugs throughout the body
Correct answer: B
Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.
