The nurse should follow the ABC (airway, breathing, circulation) priority framework when caring for a client with respiratory distress. The first intervention should be to assess the client's vital signs and oxygen saturation to determine the severity of the condition and the need for further interventions.

Incorrect options:

A) Administer oxygen therapy as prescribed. - This is an important intervention, but not the first one. The nurse should assess the client's oxygen saturation before administering oxygen therapy, as too much or too little oxygen can be harmful for a client with COPD.

B) Teach the client pursed-lip breathing technique. - This is a helpful intervention, but not the first one. The nurse should assess the client's respiratory status before teaching any breathing techniques, as some clients may not be able to perform them due to severe dyspnea or anxiety.

D) Provide reassurance and a calm environment for the client. - This is a supportive intervention, but not the first one. The nurse should address the client's physical needs before providing emotional support, as anxiety can be exacerbated by dyspnea and hypoxia.

The client with type 2 diabetes mellitus who is undergoing a colonoscopy may need to adjust their oral antidiabetic medication dose, as they will be fasting before and after the procedure and may receive sedatives or analgesics that can affect their blood glucose levels. The best response by the nurse is to advise the client to contact their health care provider for specific instructions on how to adjust their medication dose, as this may vary depending on the type and dosage of medication, the duration of fasting, and the client's blood glucose levels.

Incorrect options:

A) "You should take your usual dose of oral antidiabetic medication in the morning before the procedure." - This is an incorrect response, as taking the usual dose of oral antidiabetic medication without eating can cause hypoglycemia, which can be dangerous for the client.

B) "You should check your blood glucose levels frequently and drink clear liquids with sugar if they are low." - This is an incorrect response, as drinking clear liquids with sugar can interfere with the bowel preparation and affect the quality of the colonoscopy. The client should follow the instructions for bowel preparation and avoid any liquids that are not clear or contain red or purple dye.

C) "You should skip your oral antidiabetic medication on the day of the procedure and resume it after you eat." - This is an incorrect response, as skipping oral antidiabetic medication can cause hyperglycemia, which can increase the risk of complications during and after the procedure.

A jar opener is an assistive device that can help a client with RA open jars and bottles more easily by providing leverage and reducing strain on the joints. A jar opener can improve the client's independence and quality of life by facilitating activities of daily living.

Incorrect options:

B) A reacher - This is an assistive device that can help a client with RA reach objects that are high or low without bending or stretching. However, it does not address the specific problem of opening jars and bottles.

C) A walker - This is an assistive device that can help a client with RA maintain balance and stability while walking. However, it does not address the specific problem of opening jars and bottles.

D) A cane - This is an assistive device that can help a client with RA reduce pressure and pain on the affected joints while walking. However, it does not address the specific problem of opening jars and bottles.

The nurse should demonstrate empathy and compassion when caring for a client with CKD who is feeling depressed and hopeless. Empathy is the ability to understand and share the feelings of another person, while compassion is the willingness to help alleviate their suffering. The nurse should acknowledge the client's feelings, validate their emotions, and offer support and encouragement.

Incorrect options:

A) "You should be grateful that you have access to dialysis. Many people with CKD don't have that option." - This statement does not demonstrate empathy or compassion, but rather minimizes the client's feelings and implies that they are ungrateful or selfish.

B) "You have a chronic condition that requires lifelong treatment. You need to accept that and move on." - This statement does not demonstrate empathy or compassion, but rather dismisses the client's feelings and implies that they are weak or irrational.

C) "You are not alone in this situation. There are many people who have CKD and cope well with dialysis." - This statement does not demonstrate empathy or compassion, but rather compares the client to others and implies that they are abnormal or inadequate.
