A nurse is educating a patient with diabetes mellitus about the chronic complications associated with the disease. What information should be included in the teaching?
A. Schedule and keep appointments for annual eye exams.
Diabetes mellitus can lead to several chronic complications, including retinopathy, which can cause blindness. Regular eye exams are crucial for early detection and treatment of diabetic retinopathy. Therefore, scheduling and keeping appointments for annual eye exams is an important part of managing diabetes.
B. Ensure adequate fluid intake to prevent kidney damage.
While adequate fluid intake is generally important for overall health, it is not specifically effective in preventing kidney damage in patients with diabetes mellitus. Kidney damage in diabetes, also known as diabetic nephropathy, is caused by high blood sugar levels over time, not by dehydration.
C. Cardiac enzymes will be checked every 6 months.
Regular checks of cardiac enzymes are not a standard part of diabetes management. Cardiac enzymes are typically checked in the context of suspected heart disease or a heart attack, not as a routine measure in diabetes care.
D. Podiatry exams are necessary every 3 months.
While regular foot care is important in diabetes to prevent complications such as foot ulcers and infections, podiatry exams every 3 months are not typically necessary unless the patient has a history of foot problems or a high risk of foot complications.

Full Explanation
Choice A rationale
Diabetes mellitus can lead to several chronic complications, including retinopathy, which can cause blindness. Regular eye exams are crucial for early detection and treatment of diabetic retinopathy.

Choice B rationale
While adequate fluid intake is generally important for overall health, it is not specifically effective in preventing kidney damage in patients with diabetes mellitus. Kidney damage in diabetes, also known as diabetic nephropathy, is caused by high blood sugar levels over time, not by dehydration.
Choice C rationale
Regular checks of cardiac enzymes are not a standard part of diabetes management. Cardiac enzymes are typically checked in the context of suspected heart disease or a heart attack, not as a routine measure in diabetes care.

A patient diagnosed with deep vein thrombosis asks the nurse, “How does this blood thinner heparin work?” Which response is most accurate?
A. Heparin makes the blood less thick and easier to flow.
Heparin does not actually thin the blood or make it less thick. Instead, it works by increasing the activity of antithrombin, a protein that inhibits blood clotting. This prevents new clots from forming and existing clots from growing larger.
B. Heparin dissolves the clot and decreases the formation of platelets.
Heparin does not dissolve clots or decrease the formation of platelets. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa, two key players in the blood clotting process.
C. Heparin does not thin the blood; it prevents new clots from forming.
This statement is accurate. Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
D. Heparin decreases the number of platelets so the blood flows more easily.
Heparin does not decrease the number of platelets or make the blood flow more easily. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa.

The nurse identifies the problem of Fluid Volume Excess for a patient. Which assessment finding validates this problem?
A. Urine specific gravity 1.012.
Fluid Volume Excess (FVE), or hypervolemia, refers to an isotonic expansion of the ECF due to an increase in total body sodium content and an increase in total body water. This fluid overload usually occurs from compromised regulatory mechanisms for sodium and water as seen commonly in heart failure (CHF), kidney failure, and liver failure. The key signs of hypervolemia include weight gain and swelling. One of the defining characteristics of FVE is an increase in urine specific gravity. Therefore, a urine specific gravity of 1.012 can validate the problem of Fluid Volume Excess for a patient.
B. +4 Pedal pulses.
+4 Pedal pulses indicate a very bounding and strong pulse, which is not directly related to Fluid Volume Excess. While it might be observed in some cases due to increased blood volume and pressure, it is not a specific or primary indicator of this condition.
C. Respiratory rate 20/minute.
A respiratory rate of 20/minute is within the normal range for an adult (12-20 breaths per minute) and does not specifically indicate Fluid Volume Excess. While respiratory changes can occur with severe or prolonged Fluid Volume Excess, a normal respiratory rate does not validate this diagnosis.
D. Potassium level 3.8 mEq/L.
A potassium level of 3.8 mEq/L is within the normal range (3.5-5.0 mEq/L) and does not specifically indicate Fluid Volume Excess. While electrolyte imbalances can occur with Fluid Volume Excess, a normal potassium level does not validate this diagnosis.

The physician has just informed a patient that they have breast cancer and will require a mastectomy. The nurse finds that the patient is crying.
Which response by the nurse is most appropriate?
A. “This must be very difficult for you. I am here if you want to talk.”.
When a patient is informed about a serious diagnosis like breast cancer and the need for a mastectomy, it is common for them to experience a range of emotions, including sadness, fear, and anxiety. As a nurse, providing emotional support and creating a safe space for the patient to express their feelings is crucial. Offering to be there for the patient if they want to talk acknowledges their emotional distress and provides comfort.
B. “Can you tell me why you are so upset?”
Asking the patient why they are upset may come across as insensitive or dismissive. The patient has just received a life-changing diagnosis, and their emotional reaction is completely normal and expected. It’s important to provide support and empathy rather than questioning their feelings.
C. “I am sure everything will be alright. There is no need to cry.”.
Telling the patient that everything will be alright and there is no need to cry may seem comforting, but it can actually invalidate the patient’s feelings. It’s important to acknowledge the patient’s emotions and allow them to express their feelings without judgment.
D. “You will recover.”.
Telling the patient that they will recover may be seen as providing false reassurance. While it’s important to maintain hope, it’s also crucial to be honest and realistic with the patient about their diagnosis and treatment.
