The client has been diagnosed with type 1 diabetes mellitus and has been prescribed Humulin R insulin. The patient will take the dose at 0900. When should the client be sure to have a snack or meal?
A. 0900-0930
Humulin R (regular insulin) has an onset of 30-60 minutes and peaks at 2-3 hours. Taking a snack at 0900-0930, immediately after injection, is too early, as insulin action is minimal, and glucose from the meal may cause hyperglycemia before insulin peaks, making this timing inappropriate.
B. 1100-1130
Humulin R peaks at 2-3 hours (1100-1200 for a 0900 dose), when hypoglycemia risk is highest due to maximum glucose uptake. A snack or meal at 1100-1130 provides glucose to counter insulin’s peak effect, preventing low blood sugar, making this the most appropriate timing.
C. 1400-1430
By 1400-1430, Humulin R’s effect (duration 5-8 hours) is waning, reducing hypoglycemia risk. A snack at this time is less critical, as insulin’s glucose-lowering action is declining. This timing is less effective for preventing hypoglycemia compared to the peak action period at 1100-1130.
D. 1700-1730
At 1700-1730, Humulin R’s effect is nearly gone (duration 5-8 hours), making hypoglycemia unlikely from the 0900 dose. A snack this late is irrelevant to the insulin’s action, as glucose levels are stabilized, making this timing inappropriate for preventing hypoglycemia.

Full Explanation
Choice A reason: Humulin R (regular insulin) has an onset of 30-60 minutes and peaks at 2-3 hours. Taking a snack at 0900-0930, immediately after injection, is too early, as insulin action is minimal, and glucose from the meal may cause hyperglycemia before insulin peaks, making this timing inappropriate.
Choice B reason: Humulin R peaks at 2-3 hours (1100-1200 for a 0900 dose), when hypoglycemia risk is highest due to maximum glucose uptake. A snack or meal at 1100-1130 provides glucose to counter insulin’s peak effect, preventing low blood sugar, making this the most appropriate timing.
Choice C reason: By 1400-1430, Humulin R’s effect (duration 5-8 hours) is waning, reducing hypoglycemia risk. A snack at this time is less critical, as insulin’s glucose-lowering action is declining. This timing is less effective for preventing hypoglycemia compared to the peak action period at 1100-1130.
Choice D reason: At 1700-1730, Humulin R’s effect is nearly gone (duration 5-8 hours), making hypoglycemia unlikely from the 0900 dose. A snack this late is irrelevant to the insulin’s action, as glucose levels are stabilized, making this timing inappropriate for preventing hypoglycemia.

Which statement about proton pump inhibitors (PPIs) should be included in a client education workshop?
A. PPIs are used for long-term management of ulcers and gastric reflux disease
PPIs are used for short-term treatment of ulcers and gastroesophageal reflux disease (GERD), typically 4-8 weeks, not long-term, due to risks like nutrient deficiencies or infections. Long-term use is reserved for specific conditions like Barrett’s esophagus, making this statement inaccurate for general use.
B. PPIs are useful because they are available both orally and IV
While PPIs are available orally and intravenously, this is not the primary focus of patient education. Their efficacy in suppressing acid production is more critical than administration routes. This statement is less relevant, as it does not address therapeutic use or safety considerations.
C. Treatment with PPIs causes very few adverse effects in the older client
PPIs cause adverse effects in older adults, including increased risks of fractures, Clostridium difficile infection, and vitamin B12 deficiency due to prolonged acid suppression. This statement is inaccurate, as older clients are particularly susceptible to these risks, requiring careful monitoring during PPI therapy.
D. Treatment focuses on the lowest dose for the shortest time period
PPI treatment emphasizes the lowest effective dose for the shortest duration to minimize risks like infections, fractures, or nutrient malabsorption. This approach balances acid suppression with safety, especially for ulcers or GERD, making this statement accurate and critical for patient education on safe use.

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.

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.
