A nurse is caring for a client who has a prescription for warfarin.

Which of the following laboratory tests should the nurse monitor?

Correct answer: A

a.This step is crucial because it helps maintain the sterility of the kit by ensuring that the nurse does not accidentally contaminate the sterile field with their body or clothing.This step ensures that the nurse's hands and arms do not cross over the sterile field, reducing the risk of contamination.

b.Opening the flap nearest to the nurse first can lead to contamination because the nurse's hands and arms might cross over the sterile field while opening the remaining flaps. This increases the risk of introducing pathogens into the sterile area, compromising the sterility required for the procedure.

c.Opening a side flap first can also compromise the sterility of the field. Similar to option (b), this action might result in the nurse's hands or arms moving over the sterile area, risking contamination.

d.Applying sterile gloves is an essential step in maintaining sterility, but it is not the first step. The nurse needs to prepare the sterile field before donning sterile gloves to ensure that the gloves themselves remain uncontaminated. If the nurse were to put on sterile gloves first, there is a risk of contaminating the gloves while opening the sterile kit, thereby defeating the purpose of using sterile gloves.

Choice A Reason:

Improved respiratory function is incorrect. Pancrelipase primarily helps with the digestion and absorption of fats and fat-soluble vitamins. It does not directly impact respiratory function. Respiratory improvement in cystic fibrosis typically involves treatments such as airway clearance techniques, bronchodilators, and antibiotics to manage lung infections.

Choice B Reason:

Reduced fat in the stools is correct. Pancrelipase is an enzyme replacement therapy used to treat individuals with cystic fibrosis, a condition that affects the pancreas's ability to produce digestive enzymes. Cystic fibrosis leads to the malabsorption of nutrients, especially fats. Pancrelipase supplements these digestive enzymes and helps the child digest and absorb fat properly. As a result, one of the expected therapeutic effects of pancrelipase is a reduction in fat in the stools, as the enzymes aid in the digestion of dietary fats, leading to improved absorption of nutrients. This, in turn, can help address malnutrition and promote overall health in individuals with cystic fibrosis.

Choice C Reason:

Improved absorption of vitamins B and C is incorrect. While pancrelipase can help with the absorption of fat-soluble vitamins (A, D, E, and K), it does not directly affect the absorption of vitamins B and C, which are water-soluble vitamins. Cystic fibrosis primarily affects the absorption of fat-soluble vitamins due to impaired fat digestion.

Choice D Reason:

Decreased sodium excretion is incorrect. Cystic fibrosis is associated with excessive loss of salt (sodium chloride) in sweat. Pancrelipase does not directly affect sodium excretion. Treatment for managing sodium loss typically involves salt supplementation and ensuring proper hydration.
