Nursing Elites

1. Which of the following lipid abnormalities is a risk factor for the development of atherosclerosis and peripheral vascular disease?

• A. Low concentration of triglycerides.
• B. High levels of high-density lipoprotein (HDL) cholesterol.
• C. High levels of low-density lipoprotein (LDL) cholesterol.
• D. Low levels of LDL cholesterol.

Correct answer: C

Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.

2. The nurse is preparing to administer clarithromycin to a patient. When performing a medication history, the nurse learns that the patient takes warfarin to treat atrial fibrillation. The nurse will perform which action?

• A. Ask the provider if azithromycin may be used instead of clarithromycin.
• B. Obtain an order for continuous cardiovascular monitoring.
• C. Request an order for periodic serum warfarin levels.
• D. Withhold the clarithromycin and notify the provider.

Correct answer: C

Rationale: When a patient taking warfarin also needs to receive clarithromycin, it is essential to monitor periodic serum warfarin levels. Macrolides, including clarithromycin, can increase serum levels of drugs like warfarin. Monitoring serum drug levels helps ensure that the patient's warfarin dose can be adjusted, if necessary, to maintain therapeutic levels. Asking about using azithromycin instead is not the most appropriate action in this situation, as all macrolides can interact with warfarin. Continuous cardiovascular monitoring is not indicated solely based on the use of clarithromycin. Withholding the clarithromycin without proper assessment could delay necessary treatment and is not the best initial action.

3. A client with a diagnosis of hypothermia is being admitted to the hospital by a nurse. Which of the following signs does the nurse anticipate that this client will exhibit?

• A. Increased heart rate and increased blood pressure
• B. Increased heart rate and decreased blood pressure
• C. Decreased heart rate and increased blood pressure
• D. Decreased heart rate and decreased blood pressure

Correct answer: D

Rationale: Hypothermia decreases the heart rate and blood pressure due to reduced metabolic needs of the body. With lower metabolic demands, the heart's workload decreases, leading to reductions in both heart rate and blood pressure. Choices A, B, and C are incorrect because hypothermia typically results in a decrease in heart rate and blood pressure, not an increase.

4. The client with type 1 diabetes mellitus is taught to take isophane insulin suspension NPH (Humulin N) at 5 PM each day. The client should be instructed that the greatest risk of hypoglycemia will occur at about what time?

• A. 11 AM, shortly before lunch.
• B. 1 PM, shortly after lunch.
• C. 6 PM, shortly after dinner.
• D. 1 AM, while sleeping.

Correct answer: D

Rationale: The correct answer is D, 1 AM, while sleeping. Isophane insulin suspension NPH (Humulin N) peaks around 6-8 hours after administration, which increases the risk of hypoglycemia during the night. Choice A, 11 AM, shortly before lunch, is incorrect because the peak effect of NPH insulin occurs much later. Choice B, 1 PM, shortly after lunch, is incorrect as it is too early for the peak effect of NPH insulin. Choice C, 6 PM, shortly after dinner, is also incorrect because the peak risk of hypoglycemia with NPH insulin occurs later in the night.

5. When conducting discharge teaching for a client diagnosed with diverticulosis, which diet instruction should the nurse include?

• A. Eat a high-fiber diet and increase fluid intake.
• B. Have small frequent meals and sit up for at least two hours after meals.
• C. Eat a bland diet and avoid spicy foods.
• D. Eat a soft diet with increased intake of milk and milk products.

Correct answer: A

Rationale: A high-fiber diet with increased fluid intake is the most appropriate diet instruction for a client diagnosed with diverticulosis. High-fiber foods help prevent constipation and promote bowel regularity, reducing the risk of complications such as diverticulitis. Adequate fluid intake is crucial to soften stool and aid in digestion. Choice B, having small frequent meals and sitting up after meals, may be beneficial for some gastrointestinal conditions but is not specific to diverticulosis. Choice C, eating a bland diet and avoiding spicy foods, is not necessary for diverticulosis management. Choice D, consuming a soft diet with increased milk and milk products, may worsen symptoms in diverticulosis due to the potential for increased gas production and bloating.
