The health care provider recommends daily fiber supplements for an elderly client who is experiencing frequent constipation. What statement is important for the nurse to include when educating a client about these supplements?
A. Bulk-forming agents decrease the absorption of nutrients in the intestines so you will need a daily vitamin
Bulk-forming fiber supplements, like psyllium, increase stool bulk without significantly decreasing nutrient absorption. While high doses may slightly affect mineral uptake, routine vitamin supplementation is not required. This statement is inaccurate, as nutrient malabsorption is not a primary concern with fiber supplements.
B. Fiber can exacerbate your constipation if you do not drink at least 8 glasses of water daily
Fiber supplements require adequate hydration (at least 8 glasses of water daily) to swell and soften stool, promoting bowel movements. Insufficient water can cause fiber to harden, worsening constipation. This statement is accurate, as hydration is critical for the efficacy and safety of fiber supplements.
C. If you take fiber long term, you can become dependent on it to have a bowel movement
Long-term fiber use does not cause dependency; it mimics natural dietary fiber, promoting regular bowel movements. The colon adapts to increased bulk without losing intrinsic motility. This statement is inaccurate, as fiber supports, not undermines, normal bowel function in chronic use.
D. Your bowel regimen will improve if you delay responding to your urge to defecate
Delaying the urge to defecate can worsen constipation by causing stool to harden and reducing rectal sensitivity. Prompt response to bowel urges promotes regularity. This statement is inaccurate, as it contradicts the goal of improving bowel regimen with fiber supplementation.

Full Explanation
Choice A reason: Bulk-forming fiber supplements, like psyllium, increase stool bulk without significantly decreasing nutrient absorption. While high doses may slightly affect mineral uptake, routine vitamin supplementation is not required. This statement is inaccurate, as nutrient malabsorption is not a primary concern with fiber supplements.
Choice B reason: Fiber supplements require adequate hydration (at least 8 glasses of water daily) to swell and soften stool, promoting bowel movements. Insufficient water can cause fiber to harden, worsening constipation. This statement is accurate, as hydration is critical for the efficacy and safety of fiber supplements.
Choice C reason: Long-term fiber use does not cause dependency; it mimics natural dietary fiber, promoting regular bowel movements. The colon adapts to increased bulk without losing intrinsic motility. This statement is inaccurate, as fiber supports, not undermines, normal bowel function in chronic use.
Choice D reason: Delaying the urge to defecate can worsen constipation by causing stool to harden and reducing rectal sensitivity. Prompt response to bowel urges promotes regularity. This statement is inaccurate, as it contradicts the goal of improving bowel regimen with fiber supplementation.

A client diagnosed with liver disease asks the nurse why the health care provider is changing the dose of the client’s medications. Which statement is the nurse’s best response?
A. You should really ask your health care provider
Redirecting the client to the provider avoids addressing the question and misses an educational opportunity. Liver disease affects drug metabolism, and the nurse can explain this. This response is inappropriate, as it fails to provide the client with accurate information about their medication adjustments.
B. The health care provider is afraid you will become dependent on the medications
Medication dose changes in liver disease are due to impaired metabolism, not dependency concerns. Dependency is unrelated to hepatic function or pharmacokinetics. This statement is inaccurate, as it misrepresents the reason for dose adjustments in the context of liver disease.
C. The usual dose of medication may be too large for your liver
Liver disease impairs drug metabolism via cytochrome P450 enzymes, reducing clearance and increasing drug levels, risking toxicity. Dose adjustments prevent adverse effects. This statement is accurate, as it directly addresses how liver dysfunction necessitates lower doses for safe and effective medication use.
D. The affinity of the medication changes with liver disease
Medication affinity (binding to receptors) is not significantly altered by liver disease. Instead, impaired hepatic metabolism affects drug clearance, not receptor interactions. This statement is inaccurate, as it misattributes dose changes to a pharmacological property unrelated to liver function.

A client presents in the emergency department with joint pain. Which condition would be least likely to cause this symptom?
A. Osteoporosis
Osteoporosis causes bone density loss, leading to fractures, not primary joint pain. Pain occurs secondary to fractures, not joint inflammation or degeneration. This condition is the least likely to cause joint pain directly, as its pathology focuses on bone fragility rather than synovial or cartilage issues.
B. Systemic lupus erythematosus
Systemic lupus erythematosus (SLE) causes joint pain due to autoimmune-mediated synovitis, affecting multiple joints symmetrically. Inflammatory cytokines drive pain and swelling, making SLE a common cause of joint pain, unlike osteoporosis, which primarily affects bone structure without direct joint involvement.
C. Osteoarthritis
Osteoarthritis causes joint pain due to cartilage degeneration and bone-on-bone friction, particularly in weight-bearing joints like knees. Mechanical stress and inflammation contribute to chronic pain, making osteoarthritis a frequent cause of joint pain, unlike osteoporosis, which lacks primary joint pathology.
D. Rheumatoid arthritis
Rheumatoid arthritis causes significant joint pain through autoimmune synovial inflammation, leading to swelling, stiffness, and cartilage damage. This systemic condition affects multiple joints, making it a primary cause of joint pain, unlike osteoporosis, which is associated with bone loss, not joint inflammation.

The client with inflammatory bowel disease is having surgery for a temporary colostomy. It will be a transverse colostomy, with the stoma located as shown. What will be the consistency of the stool from the colostomy?
A. Hard, formed stool
Hard, formed stool is typical of descending or sigmoid colostomies, where the colon reabsorbs water. A transverse colostomy, located higher in the colon, has less water absorption, producing liquid stool. This statement is inaccurate, as transverse colostomy stool is not hard or formed.
B. Mostly liquid feces with mucus
A transverse colostomy, located in the mid-colon, produces mostly liquid feces with mucus due to limited water reabsorption before the stoma. The proximal colon’s contents are less formed, and mucus from inflammation (common in IBD) is present, making this statement accurate for stool consistency.
C. Soft, semi-formed stool
Soft, semi-formed stool is more typical of descending colostomies, where water absorption occurs longer. Transverse colostomies, higher in the colon, produce more liquid output due to shorter transit time. This statement is inaccurate, as it does not reflect transverse colostomy stool consistency.
D. Dry, pellet-like stool
Dry, pellet-like stool is characteristic of constipation or distal colon output, not a transverse colostomy. The transverse colon’s contents are liquid due to minimal water reabsorption, especially in IBD with inflammation. This statement is inaccurate, as it misrepresents the expected stool consistency.
