ATI Comprehensive Exit Exam 2023 With NGN Quizlet
1. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?
- A. First-degree AV block.
- B. Premature ventricular contraction.
- C. Sinus bradycardia.
- D. Atrial fibrillation.
Correct answer: A
Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.
2. What is the primary role of albumin in the blood?
- A. Transport oxygen throughout the body.
- B. Serve as a key clotting factor.
- C. Maintain osmotic pressure and fluid balance.
- D. Act as an immune response molecule.
Correct answer: C
Rationale: The correct answer is C: Maintain osmotic pressure and fluid balance. Albumin plays a crucial role in maintaining osmotic pressure by helping to retain fluid within the blood vessels. This function is essential for regulating blood volume and preventing fluid from leaking out into tissues. Choices A, B, and D are incorrect because albumin is not primarily responsible for transporting oxygen, acting as a clotting factor, or functioning as an immune response molecule in the blood.
3. Why are neonates predisposed to problems with thermoregulation?
- A. Renal function is not fully developed.
- B. Flexed posture favors heat loss.
- C. A large body surface area favors heat loss to the environment.
- D. A thick layer of subcutaneous fat provides excellent insulation.
Correct answer: C
Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.
4. A nurse manager is reviewing documentation with a newly licensed nurse. Which of the following notations by the newly licensed nurse indicates an understanding of the teaching?
- A. ''OOB with assistance for breakfast''
- B. ''Given 2 mg MSO4 IM for report of pain''
- C. ''Dressing changed qd''
- D. ''Administered 8 units of regular insulin subcutaneously''
Correct answer: ''Administered 8 units of regular insulin subcutaneously''
Rationale: The correct answer demonstrates proper documentation by specifying the action taken ('Administered'), the dose ('8 units'), the medication ('regular insulin'), and the route of administration ('subcutaneously'). This notation ensures clarity and accuracy in recording the nursing intervention, aligning with best practices in documentation.
5. Which of the following are sources of water intake?
- A. Drinking fluids.
- B. Consuming water from the food we eat.
- C. Water from metabolic processes.
- D. Drinking fluids, consuming water from the food we eat, and water from metabolic processes.
Correct answer: D
Rationale: The correct answer is D. The sources of water intake include drinking fluids, consuming water from the food we eat, and water from metabolic processes. Water intake is not solely from the liquids we drink but also from the water content present in the food we consume and the water produced during metabolic processes such as cellular respiration. Therefore, option D is the correct answer as it covers all the sources of water intake. Options A, B, and C alone do not encompass all the sources of water intake, making them incorrect choices.
