Nursing Elites

1. Which lab value is critical for a patient on heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.

2. A nurse is providing dietary teaching to a client who has a new diagnosis of chronic kidney disease. Which of the following foods should the nurse instruct the client to avoid?

• A. Baked chicken
• B. Bananas
• C. Lean cuts of beef
• D. Canned soup

Correct answer: D

Rationale: The correct answer is D: Canned soup. Canned soups are typically high in sodium, which can lead to fluid retention in clients with chronic kidney disease. Sodium restriction is crucial in managing this condition. Choice A, baked chicken, is a lean protein source that is generally recommended for individuals with kidney disease. Bananas (Choice B) are high in potassium, so clients with kidney disease may need to limit their intake depending on their individual treatment plan. Lean cuts of beef (Choice C) can be a good source of protein and iron for clients with kidney disease as long as portion sizes are controlled to manage protein intake.

3. A nurse is caring for a client who has a new prescription for levothyroxine. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Calcium
• B. Sodium
• C. Thyroid-stimulating hormone (TSH)
• D. Magnesium

Correct answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.

4. A nurse is caring for a client who has a nasogastric tube in place. Which of the following actions should the nurse take to prevent aspiration?

• A. Elevate the head of the bed 45 degrees during feedings.
• B. Place the client in the left lateral position for 30 minutes after feedings.
• C. Flush the tube with 30 mL of sterile water before each feeding.
• D. Check gastric residuals every 8 hours.

Correct answer: A

Rationale: The correct action to prevent aspiration in a client with a nasogastric tube is to elevate the head of the bed to 45 degrees during feedings. This positioning helps reduce the risk of regurgitation and aspiration of gastric contents. Placing the client in the left lateral position after feedings does not directly prevent aspiration. Flushing the tube with sterile water before each feeding is important for tube patency but does not specifically prevent aspiration. Checking gastric residuals every 8 hours is necessary to monitor the client's tolerance to feedings but is not a direct preventive measure against aspiration.

5. A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?

• A. White blood cell count of 6,000/mm³
• B. Urine specific gravity of 1.025
• C. History of asthma
• D. History of allergy to shellfish

Correct answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.
