Nursing Elites

1. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

• A. COPD clients are stimulated to breathe by hypoxia.
• B. COPD clients depend on a low carbon dioxide level.
• C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
• D. COPD clients thrive on a high oxygen level.

Correct answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

2. The client is preparing to undergo a total hysterectomy for advanced cervical cancer. The client is crying and says that she wants to have more children and is unsure if she should have the procedure. What should the nurse do?

• A. Allow the client to honestly discuss her fears and encourage her to talk more with her physician.
• B. Tell her the good things that she will be able to do without more children and encourage her to make a list of positive things.
• C. Explain to the client that her ovaries can be frozen for egg harvesting at a later time and she can find a surrogate.
• D. Advise the client to put off having the surgery until she is sure that she wants to undergo the procedure and notify the surgeon of the decision.

Correct answer: A

Rationale: In this situation, the most appropriate action for the nurse is to allow the client to express her fears and concerns openly. By encouraging her to talk more with her physician, the nurse is promoting effective communication and ensuring that the client receives adequate information to make an informed decision. Option A is correct because it acknowledges the client's emotions and empowers her to seek clarification and support from her healthcare provider. Options B and C do not address the client's emotional needs or provide a solution to her concerns regarding fertility. Option D is not appropriate as it does not prioritize the client's emotional well-being and delays necessary medical treatment for advanced cervical cancer.

3. 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.

4. A client who is newly diagnosed with Parkinson's disease and beginning medication therapy asks the nurse, 'How soon will I see improvement?' The nurse's best response is:

• A. "That varies from client to client."?
• B. "You should discuss that with your physician."?
• C. "You should notice a difference in a few days."?
• D. "It might take several weeks before you notice improvement."?

Correct answer: D

Rationale: In the case of Parkinson's disease, improvement in symptoms may take several weeks of therapy to become noticeable. Therefore, the correct answer is to inform the client that it might take several weeks before they notice improvement. Choice A acknowledges individual variability but does not provide a specific timeframe, making it less reassuring. Choice B suggests deferring the question to the physician, which is not the most supportive response. Choice C is incorrect because improvement in Parkinson's disease symptoms typically does not occur within a few days.

5. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?

• A. A three-hour-old just waking up after a period of sleep
• B. A two-day-old crying loudly
• C. A three-day-old two hours after circumcision
• D. A one-hour-old sucking his fist

Correct answer: A

Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.
