NCLEX Question of The Day
1. A client is admitted to the floor with vomiting and diarrhea for three days. She is receiving IV fluids at 200cc/hr via pump. A priority action for the nurse would be:
- A. Obtaining Intake and Output.
- B. Frequent lung assessments.
- C. Vital signs every shift.
- D. Monitoring the IV site for infiltration.
Correct answer: D
Rationale: In this scenario, the correct priority action for the nurse would be monitoring the IV site for infiltration. The client is receiving IV fluids at a rapid rate, making it crucial to ensure that the IV site is intact and not causing any complications like infiltration, which can lead to tissue damage. While frequent lung assessments are important for detecting signs of fluid overload, in this case, ensuring the IV site's integrity takes precedence. Obtaining Intake and Output is relevant but not the priority over monitoring the IV site. Vital signs are essential, but given the situation, the immediate concern is the IV site's condition to prevent complications.
2. A nurse is teaching a client newly diagnosed with Emphysema about the disease process. Which of the following statements best explains the problems associated with emphysema and could be adapted for use in the nurse's discussion with the client?
- A. Hyperactivity of the medium-sized bronchi caused by an inflammatory response leads to wheezing and tightness in the chest.
- B. Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.
- C. Vasodilation, congestion, and mucosal edema cause a chronic cough and sputum production.
- D. Chloride is not being transported properly, producing excess absorption of water and sodium, and thick viscous mucus
Correct answer: B
Rationale: The correct answer is: 'Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.' Emphysema is a breakdown of the elastin and fiber network of the alveoli where the alveoli enlarge or the walls are destroyed. This alveolar destruction leads to the formation of larger-than-normal air spaces. Emphysema is one of a group of pulmonary diseases of a chronic nature characterized by increased resistance to airflow; the entity is part of chronic obstructive pulmonary disease (COPD). Choice A is incorrect because emphysema is not primarily characterized by hyperactivity of the medium-sized bronchi causing wheezing and tightness in the chest. Choice C is incorrect because vasodilation, congestion, and mucosal edema are not the primary mechanisms involved in emphysema, and they do not directly lead to chronic cough and sputum production. Choice D is incorrect because emphysema is not related to chloride transport issues and thick viscous mucus production.
3. Why is it often necessary to draw a complete blood count and differential (CBC/differential) when a client is being treated with an antiepileptic drug (AED)?
- A. The hematocrit is adversely affected due to increased vascular volume.
- B. AEDs can lead to blood dyscrasia as a side effect.
- C. AEDs may cause aplastic anemia and megaloblastic anemia.
- D. Some AEDs induce white blood cell reduction.
Correct answer: B
Rationale: When a client is being treated with antiepileptic drugs (AEDs), it is essential to monitor for potential side effects on blood parameters. Some AEDs can lead to blood dyscrasia, which includes conditions like aplastic anemia and megaloblastic anemia. Therefore, drawing a complete blood count and differential helps in identifying these adverse effects early. Choices A, C, and D are incorrect because the primary concern when monitoring blood parameters in clients on AEDs is the risk of blood dyscrasia, not changes in hematocrit due to vascular volume, white blood cell reduction, or immune modulation.
4. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: A
Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.
5. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
