1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

A. Semipermeable membranes.
B. Hydration.
C. Osmotic pressure.
D. Perspiration.

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

2. A client with gastroesophageal reflux disease is being taught by a nurse about managing the illness. Which of the following recommendations should the nurse include in the teaching?

A. Limit fluid intake not related to meals.
B. Chew on mint leaves to relieve indigestion.
C. Avoid eating within 3 hours of bedtime.
D. Season foods with black pepper.

Correct answer: C

Rationale: The correct recommendation for managing gastroesophageal reflux disease is to avoid eating within 3 hours of bedtime. This helps prevent acid reflux by allowing food to digest before lying down. Choices A, B, and D are incorrect. Limiting fluid intake not related to meals is not a standard recommendation for managing GERD. Chewing on mint leaves may worsen symptoms as mint can relax the lower esophageal sphincter, allowing stomach acid to flow back up. Seasoning foods with black pepper does not specifically help manage GERD.

3. Why is atherosclerosis dangerous to arterial function?

A. It diminishes central circulation
B. It causes decreased blood pressure on artery walls
C. It narrows the arterial lumen so a clot can easily block it
D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

4. The following are appropriate nursing interventions during colostomy irrigation, EXCEPT:

A. Increase the irrigating solution flow rate when abdominal cramps is felt
B. Insert 2-4 inches of an adequately lubricated catheter to the stoma
C. Position client in semi-Fowler
D. Hang the solution 18 inches above the stoma

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

5. Hypertrophic burn scars are caused by:

A. exaggerated contraction
B. random layering of collagen
C. wound ischemia
D. delayed epithelialization

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
