NurseDive Free Nursing Practice Question
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.

The illustration shows various types of fracture. Select the one that depicts a greenstick fracture.
A. Complete break with both ends aligned
A complete break with both ends aligned is a simple or non-displaced fracture, not a greenstick fracture. Greenstick fractures involve partial breakage with bending, common in children due to flexible bones. This description does not match the characteristic bending of greenstick fractures.
B. Partial break with one side bent
A greenstick fracture is a partial break where one side of the bone bends and the other cracks, like a green twig. This occurs in children due to pliable bones with a thick periosteum. This description accurately depicts a greenstick fracture, making it the correct choice.
C. Break with bone piercing the skin
A break with bone piercing the skin is a compound (open) fracture, not a greenstick fracture. Compound fractures involve complete bone disruption and skin penetration, unlike the partial, bending nature of greenstick fractures, making this description incorrect for the fracture type.
D. Spiral break from twisting force
A spiral break from twisting force is a spiral fracture, characterized by a helical pattern around the bone. Greenstick fractures involve bending, not twisting, and are partial breaks. This description is inaccurate, as it describes a different fracture mechanism unrelated to greenstick fractures.
