A patient is experiencing tingling sensations in her feet and has also noticed that her tongue has become very red and painful. The nurse suspects that she has:

Correct Answer: B

Rationale: The correct answer is B: Pernicious anemia. This condition is characterized by a deficiency in vitamin B12, leading to neurological symptoms like tingling sensations in the feet (peripheral neuropathy) and glossitis, causing the tongue to become red and painful. Polycythemia (A) is an increase in red blood cell mass, not related to the symptoms described. Micronucleus anemia (C) is not a recognized medical condition. Iron-deficiency anemia (D) can lead to symptoms like fatigue and pallor, but not typically tingling sensations in the feet or glossitis.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Anticoagulants are crucial in treating DVT as they prevent blood clots from getting larger and stop new clots from forming. They help reduce the risk of complications like pulmonary embolism. Administering analgesics (B) may help with pain but does not address the root cause. Diuretics (C) are used to treat conditions like fluid retention, not DVT. Applying a warm compress (D) can actually worsen DVT by promoting blood flow. Anticoagulants are the gold standard treatment for DVT.

Correct Answer: B

Rationale: The correct answer is B: Increased shortness of breath. During a COPD exacerbation, airflow limitation worsens, leading to increased difficulty in breathing. This is a common sign due to air trapping and inflammation in the airways. Sudden weight gain (A) is not typically associated with COPD exacerbation. Decreased heart rate (C) is not a common sign and is more likely to occur in other conditions. Increased energy levels (D) are unlikely during a COPD exacerbation as the body is under stress from impaired lung function.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Washing hands before and after cord care is a standard hygiene practice to prevent infection. 2. Options A and B are incorrect as alcohol and covering the cord can lead to complications. 3. Option C suggests recognizing concerning changes in the cord, indicating good understanding. 4. Thus, option D is correct as it is a crucial step in cord care and does not indicate a need for further teaching.

Correct Answer: A

Rationale: The correct answer is A: Increasing physical activity and managing weight. This is important for stroke prevention as exercise can improve cardiovascular health and help maintain a healthy weight, reducing the risk of another stroke. Increasing sodium intake (B) can actually elevate blood pressure, increasing stroke risk. Avoiding physical activity (C) can lead to a sedentary lifestyle, which is detrimental to stroke prevention. Consuming high-calorie, high-fat foods (D) can contribute to obesity and other risk factors for stroke. Prioritizing physical activity and weight management aligns with evidence-based guidelines for stroke prevention.

Correct Answer: C

Rationale: The correct answer is C: Assessing for signs of infection. This is the priority because diabetic foot ulcers are at high risk for infection, which can lead to serious complications. By assessing for signs of infection such as redness, warmth, swelling, pus, or foul odor, the nurse can promptly identify and initiate appropriate treatment. Administering antibiotics (A) should be based on the assessment findings. Providing pain relief (B) is important but not the priority when infection is a concern. Encouraging weight-bearing activity (D) may worsen the ulcer and should be avoided initially.

Correct Answer: A

Rationale: Step 1: Cirrhosis can impair the liver's ability to store glycogen and produce glucose. Step 2: Liver dysfunction can lead to hypoglycemia due to decreased glycogen stores and gluconeogenesis. Step 3: Monitoring for hypoglycemia is crucial as it can result in serious complications. Step 4: Hyperglycemia (B) is less likely in cirrhosis as the liver's ability to regulate blood sugar is impaired. Step 5: Hypokalemia (C) and hyperkalemia (D) are less directly related to cirrhosis and are not the primary concerns in this case.

Correct Answer: A

Rationale: The correct answer is A: Administer albuterol. Albuterol is a bronchodilator that helps open airways, making it effective in treating respiratory distress. It works quickly to relieve symptoms such as shortness of breath and wheezing. Corticosteroids (B) may be used in conjunction with albuterol for severe cases, but albuterol is the immediate intervention. Providing pain relief (C) is not the primary intervention for respiratory distress. Nebulizers (D) are a delivery method for medications like albuterol, but the key intervention is administering the medication itself.

Correct Answer: C

Rationale: The correct answer is C because stopping insulin when blood sugar is normal can lead to hyperglycemia. Choice A shows understanding of managing diabetes. Choice B indicates monitoring blood sugar, crucial for diabetes management. Choice D demonstrates adherence to medication schedule, essential for controlling blood sugar levels. Stopping insulin prematurely can disrupt the balance and result in complications.
