1. 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.

2. 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.

3. What is the number one reason a person with alcohol addiction does not seek treatment?

• A. Co-dependency
• B. Denial
• C. Depression
• D. Stigma

Correct answer: B

Rationale: The correct answer is B: Denial. Individuals with alcohol addiction often deny that they have a drinking problem and may become defensive when confronted about it. This sense of denial can be a significant barrier to seeking treatment. Co-dependency, referred to in choice A, is a relationship dynamic and is not the primary reason for avoiding treatment. Depression, as mentioned in choice C, is a common co-occurring condition with alcohol addiction but is not typically the main factor preventing treatment-seeking. Stigma, as in choice D, can act as a deterrent, but denial of the problem itself is usually the primary obstacle to seeking help.

4. The client has been taking divalproex (Depakote) for the management of bipolar disorder. The nurse should give priority to monitoring which laboratory test?

• A. Alanine aminotransferase (ALT)
• B. Serum glucose
• C. Serum creatinine
• D. Serum electrolytes

Correct answer: A

Rationale: The correct answer is Alanine aminotransferase (ALT). Monitoring ALT levels is crucial when a patient is taking divalproex (Depakote) due to the risk of drug-induced hepatitis. Elevated ALT levels indicate liver damage or disorders, which can be a side effect of Depakote. Serum glucose (choice B) is not the priority for monitoring in this case, as the medication does not directly affect glucose levels. Serum creatinine (choice C) is not the most relevant test to monitor for Depakote use; it primarily assesses kidney function. Serum electrolytes (choice D) are important but do not take precedence over monitoring ALT levels when a patient is on Depakote.

5. What task should the RN perform first?

• A. Changing a burn dressing that is scheduled every four hours.
• B. Doing pinsite care on a client in skeletal traction ordered TID.
• C. Teaching a newly diagnosed diabetic about diet and exercise.
• D. Assessing a newly admitted client.

Correct answer: D

Rationale: The correct answer is to assess a newly admitted client first. When a client is newly admitted, it is crucial to perform an assessment promptly. The initial assessment and establishment of a care plan should be completed within a specific timeframe to ensure the client's needs are met effectively. Choices A, B, and C involve important tasks but should be prioritized after the initial assessment of the newly admitted client to ensure timely and appropriate care delivery. Changing a burn dressing (Choice A) and doing pinsite care on a client in skeletal traction (Choice B) are time-sensitive tasks but can be safely delayed briefly to conduct the initial assessment. Teaching a newly diagnosed diabetic about diet and exercise (Choice C) is important for the client's long-term care but can be scheduled after the immediate needs assessment of the newly admitted client.
