Which body substance should the nurse observe to evaluate the effectiveness of pancreatic enzyme replacement for a patient with chronic pancreatitis?

Stool.

Saliva.

Nasal Mucus.

Urine.

Answer and Explanation

The Correct Answer is A

Choice A rationale
The effectiveness of pancreatic enzyme replacement therapy in patients with chronic pancreatitis can be evaluated by observing the patient’s stool. Pancreatic enzyme replacement therapy (PERT) is used to improve digestion and absorption of nutrients in patients with pancreatic insufficiency, a common complication of chronic pancreatitis. One of the primary goals of PERT is to reduce steatorrhea, or fatty stools, which is a common symptom of pancreatic insufficiency. Therefore, observing changes in the patient’s stool, such as a reduction in fat content, can help evaluate the effectiveness of PERT567.
Choice B rationale
While saliva plays a role in the initial stages of digestion, it is not typically used to evaluate the effectiveness of pancreatic enzyme replacement therapy in patients with chronic pancreatitis. PERT is primarily aimed at improving the digestion and absorption of nutrients in the intestines, and changes in saliva are not indicative of the effectiveness of this therapy.
Choice C rationale
Nasal mucus is not typically used to evaluate the effectiveness of pancreatic enzyme replacement therapy in patients with chronic pancreatitis. PERT is primarily aimed at improving the digestion and absorption of nutrients in the intestines, and changes in nasal mucus are not indicative of the effectiveness of this therapy.
Choice D rationale
Urine is not typically used to evaluate the effectiveness of pancreatic enzyme replacement therapy in patients with chronic pancreatitis. PERT is primarily aimed at improving the digestion and absorption of nutrients in the intestines, and changes in urine are not indicative of the effectiveness of this therapy.

Correct Answer is B

Explanation

Choice A rationale
While chronic exposure to UV rays can cause skin dryness, it does not decrease the water content of the skin20. Skin dryness is more of a symptom rather than a risk factor for skin cancer20.

Choice B rationale
Chronic exposure to UV rays can cause an error in the skin’s genetic code20. This can lead to the development of skin cancer, as the damaged DNA can lead to uncontrolled cell growth20.
Choice C rationale
Increased blood flow to the skin is not a direct result of chronic exposure to UV rays20. While UV rays can cause skin redness and inflammation, these are not directly linked to an increased risk of skin cancer20.
Choice D rationale
Chronic exposure to UV rays does not cause degeneration of elastic fibers in skin tissue20. While UV rays can cause skin aging and wrinkles, these are not direct risk factors for skin cancer20. Diabetic retinopathyDiabetic retinopathy Explore

A. A 25-year-old planning to lose 20 pounds after childbirth. B. A 65-year-old who recently underwent hernia surgery (postoperative day 2). C. A 70-year-old who has been fasting since midnight in preparation for a colonoscopy. D. A 55-year-old who has been consuming alcohol for 35 years.

Correct Answer is D

Explanation

Choice A rationale

While a 25-year-old planning to lose 20 pounds after childbirth may have increased nutritional needs, they would not typically be considered at higher risk for malnutrition unless there were other factors such as inadequate diet or certain health conditions.
Choice B rationale
A 65-year-old who recently underwent hernia surgery might have temporary changes in diet or appetite related to the surgery, but would not typically be at high risk for malnutrition unless there were other ongoing issues such as poor diet, difficulty eating, or a chronic health condition.
Choice C rationale
A 70-year-old who has been fasting since midnight in preparation for a colonoscopy would not typically be at risk for malnutrition from this short-term fast. However, if they had ongoing issues with diet, appetite, or a chronic health condition, they could potentially be at risk.
Choice D rationale
A 55-year-old who has been consuming alcohol for 35 years is at higher risk for malnutrition. Alcohol can interfere with the body’s ability to absorb and use nutrients, and individuals with long-term heavy alcohol use may also have other lifestyle factors that increase their risk for malnutrition.
