Chapter 13: Diabetes Mellitus Flashcards
The nurse is caring for an older patient with type 1 diabetes and diabetic retinopathy. What is the nurse’s priority concern for assessing this patient?
- Assess ability to measure and inject insulin and to monitor blood glucose levels.
- Assess for damage to motor fibers, which can result in muscle weakness.
- Assess which modifiable risk factors can be reduced.
- Assess for albuminuria, which may indicate kidney disease.
Ans: 1
The older patient with diabetic retinopathy also has general age- related vision changes, and the ability to perform self-care may be seriously affected. He or she may have blurred vision, distorted central vision, fluctuating vision, loss of color perception, and mobility problems resulting from loss of depth perception. When a patient has visual changes, it is especially important to assess his or her ability to measure and inject insulin and to monitor blood glucose levels to determine if adaptive devices are needed to assist in self-management. The other options are important but are not specific to diabetic retinopathy. Focus: Prioritization.
An older patient with type 2 diabetes has cardiovascular autonomic neuropathy (CAN). Which instruction would the nurse provide for the unlicensed assistive personnel (UAP) assisting the patient with morning care?
- Provide a complete bed bath for this patient.
- Sit the patient up slowly on the side of the bed before standing.
- Only let the patient wash his or her face and brush his or her teeth.
- Be sure to provide rest periods between activities.
Ans: 2
CAN affects sympathetic and parasympathetic nerves of the heart and blood vessels. It may lead to orthostatic (postural) hypotension and syncope (brief loss of consciousness on standing) caused by failure of the heart and arteries to respond to position changes by increasing heart rate and vascular tone. The nurse should be sure to instruct the UAP to have the patient change positions slowly when moving from lying to sitting and standing. Focus: Supervision, Delegation.
The nurse is preparing to review a teaching plan for a patient with type 2 diabetes mellitus. To determine the patient’s level of compliance with his prescribed diabetic regimen, which value would the nurse be sure to review?
- Fasting glucose level
- Oral glucose tolerance test results
- Glycosylated hemoglobin (HgbA1c) level
- Fingerstick glucose findings for 24 hours
Ans: 3
The higher the blood glucose level is over time, the more glycosylated the hemoglobin becomes. The HgbA1c level is a good indicator of the average
blood glucose level over the previous 120 days. Fasting glucose and oral glucose tolerance tests are important diagnostic tools. Fingerstick blood glucose monitoring provides information that allows adjustment of the patient’s therapeutic regimen. Focus: Prioritization.
A patient has newly-diagnosed type 2 diabetes. Which task should the RN delegate to an experienced unlicensed assistive personnel (UAP)?
- Arranging a consult with the dietitian
- Assessing the patient’s insulin injection technique
- Teaching the patient to use a glucometer to monitor glucose at home
- Checking the patient’s glucose level before each meal
Ans: 4
The experienced UAP would have been taught to perform tasks such as checking pulse oximetry and glucose checks, and these actions would be part of his or her scope of practice. Arranging for a consult with the dietitian is appropriate for the unit clerk. Teaching and assessing require additional education and should be carried out by licensed nurses. Focus: Delegation, Supervision, Assignment.
A patient with newly diagnosed diabetes has peripheral neuropathy. Which key points should the nurse include in the teaching plan for this patient? Select all that apply.
- “Clean and inspect your feet every day.”
- “Be sure that your shoes fit properly.”
- “Nylon socks are best to prevent friction on your toes from shoes.”
- “Only a podiatrist should trim your toenails.”
- “Report any nonhealing skin breaks to your health care provider (HCP).”
- “Use a thermometer to check the temperature of water before taking a bath.”
Ans: 1, 2, 5, 6
Sensory alterations are the major cause of foot complications in patient with diabetes, and patients should be taught to examine their feet on a daily basis. Properly fitted shoes protect the patient from foot complications. Broken skin increases the risk of infection. Cotton socks are recommended to absorb moisture. Using a bath thermometer can prevent burn injuries. Patients, family, or HCPs may trim toenails. Focus: Prioritization; Test Taking Tip: When caring for patients with diabetes, the nurse must be knowledgeable about safety issues with the potential for injuries to these patients. A key nursing role is patient teaching regarding these concerns so patients can perform protective interventions in the home to prevent injuries.
An LPN/LVN is assigned to perform assessments on two patients with diabetes. Assessments reveals all of these findings. Which finding would the RN instruct the LPN/LVN to report immediately?
- Fingerstick glucose reading of 185 mg/dL (10.3 mmol/L) 2. Numbness and tingling in both feet
- Profuse perspiration
- Bunion on the left great toe
Ans: 3
Profuse perspiration is a symptom of hypoglycemia, a complication of diabetes that requires urgent treatment. A glucose level of 185 mg/dL (10.3 mmol/L) will need coverage with sliding-scale insulin, but this is not urgent. Numbness and tingling, as well as bunions, are related to the chronic nature of diabetes and are not urgent problems. Focus: Prioritization.
The plan of care for a patient with diabetes includes all of these interventions. Which intervention should the nurse delegate to unlicensed assistive personnel (UAP)?
- Reminding the patient to put on well-fitting shoes before ambulating
- Discussing community resources for diabetic outpatient care
- Teaching the patient to perform daily foot inspection
- Assessing the patient’s technique for drawing insulin into a syringe
Ans: 1
Reminding the patient to put on well-fitting shoes (after the nurse has taught the patient about the importance of this action) is part of assisting with activities of daily living and is within the education and scope of practice of the UAP. It is a safety measure that can prevent injury. Discussing community resources, teaching, and assessing require a higher level of education and are appropriate to the scope of practice of licensed nurses. Focus: Delegation.
A 58-year-old patient with type 2 diabetes was admitted to the acute care unit with a diagnosis of chronic obstructive pulmonary disease (COPD) exacerbation. When the RN prepares a care plan for this patient, what would he or she be sure to include? Select all that apply.
- Fingerstick blood glucose checks before meals and at bedtime
- Sliding-scale insulin dosing as prescribed
- Bed rest until the COPD exacerbation is resolved
- Teaching about the Atkins diet for weight loss
- Demonstration of the components of foot care
- Discussing the relationship between illness and glucose levels
Ans: 1, 2, 5, 6
When a patient with diabetes is ill, glucose levels become elevated, and administration of insulin may be necessary. Administration of sliding-scale insulin is guided by fingerstick blood glucose checks. Teaching or reviewing the components of proper foot care is always a good idea with a patient with diabetes. Bed rest is not necessary, and glucose levels may be better controlled when a patient is more active. The Atkins diet recommends decreasing the consumption of carbohydrates and is not a good diet for patient with diabetes. Focus: Prioritization.
An unlicensed assistive personnel (UAP) tells the nurse that while assisting with the morning care of a postoperative patient with type 2 diabetes who has been given insulin, the patient asked if she will always need to take insulin now. What is the RN’s priority for teaching the patient?
- Explain to the patient that she is now considered to have type 1 diabetes.
- Tell the patient to monitor fingerstick glucose level every 4 hours after discharge.
- Teach the patient that a person with type 2 diabetes does not always need insulin.
- Discuss the relationship between illness and increased glucose levels.
Ans: 4
When a patient with diabetes is ill or has surgery, glucose levels become elevated, and administration of insulin may be necessary. This is a temporary change that usually resolves with recovery from the illness or surgery. Option 3 is correct but does not explain why the patient may currently need insulin. The patient does not have type 1 diabetes, and fingerstick glucose checks are usually prescribed for before meals and at bedtime. Focus: Prioritization.
An LPN/LVN is assigned to administer rapid-acting insulin, lispro, to a patient with type 1 diabetes. What essential information would the RN be sure to tell the LPN/LVN?
- Give this insulin when the food tray has been delivered and the patient is ready to eat.
- Only give this insulin for fingerstick glucose reading is above 200 mg/dL (11.1 mmol/L).
- This insulin mimics the basal glucose control of the pancreas.
- Rapid-acting insulin is the only insulin that can be given subcutaneously or IV.
Ans: 1
The onset of action for rapid-acting insulin is within minutes, so it should be given only when the patient has food and is ready to eat. Because of this, rapid-acting insulin is sometimes called “see food” insulin. Options 2, 3, and 4 are incorrect with regard to rapid-acting insulin. Option 2 is incorrect with regard to all forms of insulin. Long-acting insulins mimic the action of the pancreas. Regular insulin is the only insulin that can be given IV. Focus: Assignment, Supervision.
In the care of a patient with type 2 diabetes, which actions should the nurse delegate to an unlicensed assistive personnel (UAP)? Select all that apply.
- Providing the patient with extra packets of artificial sweetener for coffee 2. Assessing how well the patient’s shoes fit
- Recording the liquid intake from the patient’s breakfast tray
- Teaching the patient what to do if dizziness or lightheadedness occurs
- Checking and recording the patient’s blood pressure
- Assisting the patient to ambulate to the bathroom
Ans: 1, 3, 5, 6
Giving the patient extra sweetener, recording oral intake, assisting with ambulation, and checking blood pressure are all within the scope of practice of the UAP. Assessing shoe fit and patient teaching are within the professional nurse’s scope of practice. Focus: Assignment.
In the emergency department, during initial assessment of a newly admitted patient with diabetes, the nurse discovers all of these findings. Which finding should be reported to the health care provider immediately?
- Hammer toe of the left second metatarsophalangeal joint
- Rapid respiratory rate with deep inspirations
- Numbness and tingling bilaterally in the feet and hands 4. Decreased sensitivity and swelling of the abdomen
Ans: 2
Rapid, deep respirations (Kussmaul respirations) are symptomatic of diabetic ketoacidosis. Hammer toe, as well as numbness and tingling, are chronic complications associated with diabetes. Decreased sensitivity and swelling (lipohypertrophy) occur at a site of repeated insulin injections, and treatment involves teaching the patient to rotate injection sites within one anatomic site. Focus: Prioritization.
The nurse is caring for a patient with diabetes who is developing diabetic ketoacidosis (DKA). Which task delegation or assignment is most appropriate?
- Ask the unit clerk to page the health care provider to come to the unit.
- Ask the LPN/LVN to administer IV push insulin according to a sliding scale.
- Ask the unlicensed assistive personnel (UAP) to hang a new bag of normal saline.
- Ask the UAP to get the patient a cup (236 mL) of orange juice.
Ans: 1
The nurse should not leave the patient. The scope of the unit clerk’s job includes calling and paging physicians. LPNs/LVNs generally do not administer IV push medication, although in some states with additional training, this may be done. (Be sure to check the Scope of Practice in your specific state.) IV fluid administration is not within the scope of practice of UAPs. Patients with DKA already have a high glucose level and do not need orange juice. Focus: Delegation, Supervision.
The RN is serving as preceptor to a new graduate nurse who has recently passed the RN licensure (NCLEX®) examination. The new nurse has only been on the unit for 2 days. Which patient should be assigned to the new graduate nurse?
- A 68-year-old patient with diabetes who is showing signs of hyperglycemia
- A 58-year-old patient with diabetes who has cellulitis of the left ankle
- A 49-year-old patient with diabetes just returned from the postanesthesia care unit after a below-knee amputation
- A 72-year-old patient with diabetes with diabetic ketoacidosis who is receiving IV insulin
Ans: 2
The new nurse is very early in orientation to the unit. Appropriate patient assignments at this time include patients whose conditions are stable and not complex. Patients 1, 3, and 4 are more complex and will benefit from care by a nurse experienced in care of patients with diabetes. Focus: Assignment; Test Taking Tip: For nurses new to a unit, always assign patients who are most stable and least complex.
A patient with diabetes has hot, dry skin; rapid and deep respirations; and a fruity odor to his breath. The charge nurse observes a newly graduated RN performing all the following patient tasks. Which action requires that the charge nurse intervene immediately?
- Checking the patient’s fingerstick glucose level
- Encouraging the patient to drink orange juice
- Checking the patient’s order for sliding-scale insulin dosing
- Assessing the patient’s vital signs every 15 minutes
Ans: 2
The signs and symptoms the patient is exhibiting are consistent with hyperglycemia. The RN should not give the patient additional glucose. All of the other interventions are appropriate for this patient. The RN should also notify the health care provider at this time. Focus: Prioritization.
