Which client commonly has more body adipose tissue and less body fluid?
A female client.
An adolescent client.
An infant client.
A male client.
The Correct Answer is A
Choice A rationale
Biological females generally have a higher percentage of body adipose tissue compared to males due to hormonal influences, particularly estrogen. Adipose tissue contains significantly less water than muscle tissue. Consequently, because females have more fat and less lean muscle mass on average, they have a lower total body water percentage relative to their total body weight. This physiological difference is important when calculating medication dosages and understanding the risks for dehydration or fluid imbalances.
Choice B rationale
Adolescents are in a stage of rapid growth where lean muscle mass is typically increasing, especially in males due to testosterone. While body fat percentages can vary widely during puberty, adolescents generally do not have more adipose tissue and less body fluid as a baseline characteristic when compared to adult females. Their total body water percentage is typically higher than that of an adult female because they have a higher proportion of lean tissue and lower cumulative fat stores.
Choice C rationale
Infants actually have the highest percentage of total body fluid of any age group, often comprising about 70 to 80 percent of their total body weight. They have relatively little adipose tissue compared to their body water content. This high fluid-to-mass ratio, combined with their immature renal function and high metabolic rate, makes infants extremely vulnerable to rapid dehydration and electrolyte imbalances. They represent the opposite of the profile described in the question regarding high fat and low fluid.
Choice D rationale
Biological males typically have a higher percentage of lean muscle mass and a lower percentage of adipose tissue than females. Since muscle tissue is approximately 75 percent water and fat tissue is only about 10 to 20 percent water, males generally have a higher total body water percentage, usually around 60 percent. This higher fluid volume provides a larger buffer against dehydration compared to the typical female body composition, which contains more fat and less total water.

Correct Answer is A
Explanation
Choice A rationale
This question is phrased as a leading question that may come across as judgmental or biased, which can hinder open communication during a focused assessment. In clinical interviewing, questions should be neutral to allow the client to provide honest reflections of their health habits. Since frequent enema use can indicate chronic constipation or dependency, the nurse must assess this without implying that the behavior is abnormal or problematic initially.
Choice B rationale
This is an appropriate, open-ended clinical question designed to identify the use of pharmacological or mechanical aids for bowel movements. It helps the nurse understand the client's reliance on laxatives, stool softeners, or herbal remedies. Understanding these interventions is crucial because excessive use of stimulants can lead to lazy bowel syndrome, where the colon loses its natural peristaltic ability. This question provides essential data for a comprehensive elimination assessment.
Choice C rationale
Asking about the frequency of bowel movements is a fundamental component of assessing elimination patterns. Normal bowel frequency varies widely among individuals, typically ranging from three times per day to three times per week. By establishing a baseline, the nurse can identify deviations such as constipation or diarrhea. This information is vital for determining if the client's current pattern aligns with their historical norm or if a new pathology exists.
Choice D rationale
This question directly addresses the client's current perception of their health status and any immediate discomfort or dysfunction. It allows the client to report symptoms like bloating, pain, or straining that might not be captured by frequency alone. Subjective data regarding bowel problems are essential for identifying issues like hemorrhoids, fecal impaction, or irritable bowel syndrome, which are common clinical concerns in a focused gastrointestinal assessment.
Correct Answer is C
Explanation
Choice A rationale
Removing a soiled dressing before washing hands and preparing the environment is a violation of infection control principles. The nurse's hands could be contaminated from other tasks, and touching a wound site without prior hygiene increases the risk of healthcare-associated infections. Furthermore, flushing the wound before having a clean field ready can lead to contamination of the surrounding area. The sequence must begin with hand hygiene and proper preparation of the sterile field to ensure safety.
Choice B rationale
Pouring the solution before washing hands or removing the old dressing is disorganized and risks contaminating the sterile solution. If the nurse pours the solution first, it sits exposed to the air while the contaminated dressing is handled, increasing the risk of airborne pathogens settling in the liquid. Hand hygiene must always be the very first step in any sterile or clean procedure to minimize the transfer of microorganisms from the nurse to the client or equipment.
Choice C rationale
The correct sequence begins with washing hands to reduce the microbial load on the nurse. Next, the nurse prepares the sterile field to ensure all necessary supplies are ready and uncontaminated. Applying clean gloves to remove the old, soiled dressing protects the nurse from pathogens in the wound drainage. After removal, the nurse discards the contaminated gloves and performs hand hygiene again before donning sterile gloves for the irrigation. This flow maintains the highest standard of surgical asepsis.
Choice D rationale
Preparing the sterile field and putting on sterile gloves before removing the soiled dressing is incorrect because the sterile gloves would become contaminated the moment they touch the old dressing. Removing a soiled dressing is a "clean" task, not a "sterile" one. Once the old dressing is gone and the area is cleaned, the nurse should then transition to sterile gloves for the actual irrigation and application of the new sterile dressing to prevent cross-contamination.
