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 with sickle cell disease is worried about passing the disease on to children. Which of the following statements by the PN is most appropriate for this client?

• A. "You should discuss the inheritance risk with your physician."?
• B. "Sickle cell disease is genetically based and might be passed on to children."?
• C. "Sickle cell disease is genetically based and is not passed on to children."?
• D. "Sickle cell disease is caused by an infection and cannot be passed on to children."?

Correct answer: B

Rationale: A client with sickle cell disease has a genetic condition that can be passed on to their offspring. The most appropriate statement for the PN to provide is to acknowledge this fact and inform the client that sickle cell disease is genetically based and might be passed on to children. This empowers the client with accurate information. Choice A has been refined to emphasize discussing the inheritance risk, making it a better option than the vague original choice. Choices C and D provide incorrect information. Sickle cell disease is indeed genetically based and can be inherited.

3. When dressing a severe burn to the right hand, it is important for the nurse to:

• A. Apply a wet-to-dry dressing for debridement
• B. Wrap each digit individually to prevent webbing
• C. Open blisters to allow drainage prior to dressing
• D. Allow the client to do as much of the dressing change as possible

Correct answer: B

Rationale: When dressing a severe burn to the hand, it is crucial to wrap each digit individually to prevent webbing, which can lead to contractures and impaired function. Applying a wet-to-dry dressing for debridement is not recommended for burn wounds as it can cause trauma to the wound bed during removal. Opening blisters can increase the risk of infection and delay healing. Allowing the client to perform the dressing change may not ensure proper care and can lead to complications.

4. The charge nurse on a cardiac unit tells you a patient is exhibiting signs of right-sided heart failure. Which of the following would not indicate right-sided heart failure?

• A. Muscle tetany
• B. Syncope
• C. Numbness
• D. Anxiety

Correct answer: D

Rationale: The correct answer is 'Anxiety.' Anxiety is not a typical sign of right-sided heart failure. Right-sided heart failure usually presents with symptoms such as muscle tetany, syncope, and numbness. Muscle tetany can occur due to electrolyte imbalances seen in heart failure. Syncope can result from decreased cardiac output, leading to decreased perfusion to the brain. Numbness can occur due to poor circulation. While anxiety can be present in patients with various medical conditions, it is more commonly associated with respiratory acidosis or other psychological factors rather than right-sided heart failure.

5. The client has jaundice, elevated liver enzymes, and an elevated serum bilirubin. What color urine does the nurse expect to find?

• A. Pink-tinged
• B. Straw-colored
• C. Clear
• D. Dark amber

Correct answer: D

Rationale: The correct answer is dark amber. In jaundice, the elevated bilirubin levels are excreted in the urine, giving it a dark amber color. Choices A, B, and C are incorrect because in jaundice, the urine typically appears dark amber due to the presence of elevated bilirubin, not pink-tinged, straw-colored, or clear.
