1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. The client with newly diagnosed peptic ulcer disease (PUD) is being taught about lifestyle modifications. Which instruction should be included?

• A. Increase the intake of spicy foods
• B. Avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs)
• C. Drink coffee in moderation
• D. Eat large meals at bedtime

Correct answer: B

Rationale: The correct instruction to include when teaching a client with newly diagnosed PUD about lifestyle modifications is to avoid the use of nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs can exacerbate peptic ulcer disease by causing further irritation of the gastric mucosa. Increasing the intake of spicy foods (choice A) can aggravate the condition by irritating the stomach lining. Drinking coffee (choice C) can stimulate gastric acid secretion, which may worsen the symptoms of PUD. Eating large meals at bedtime (choice D) can also exacerbate PUD by increasing gastric acid production when the body is at rest, potentially leading to discomfort and symptoms.

3. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.

4. The nurse is caring for a client with a diagnosis of major depressive disorder who has been prescribed fluoxetine (Prozac). What is the most important teaching point?

• A. Take the medication with or without food.
• B. Report any increase in suicidal thoughts.
• C. Avoid foods high in tyramine.
• D. Expect improvement within 24 hours.

Correct answer: B

Rationale: The correct teaching point is to instruct the client to report any increase in suicidal thoughts. This is crucial because SSRIs like fluoxetine can initially increase suicidal ideation, especially at the beginning of treatment. Choice A is corrected to emphasize that fluoxetine can be taken with or without food. Choice C is unrelated as it pertains more to MAOIs than SSRIs like fluoxetine. Choice D is inaccurate as antidepressants like fluoxetine may take weeks to show significant improvement in symptoms, not within 24 hours.

5. The nurse is providing care for a client with a draining postoperative wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which is the most important action for the nurse to take?

• A. Encourage increased oral fluids.
• B. Provide high-protein snacks.
• C. Change the wound dressing.
• D. Administer prescribed antibiotics.

Correct answer: D

Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.
