Nursing Elites

1. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

2. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

3. The client has undergone a thyroidectomy, and the nurse is providing care. Which assessment finding requires immediate intervention?

• A. Hoarseness and a sore throat.
• B. Difficulty swallowing.
• C. Numbness and tingling around the mouth.
• D. Temperature of 100.2°F (37.9°C).

Correct answer: C

Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a common complication post-thyroidectomy due to inadvertent parathyroid gland removal. Immediate intervention is required to prevent severe hypocalcemia manifestations like tetany or seizures. Hoarseness and a sore throat are common after a thyroidectomy due to surgical trauma and irritation to the vocal cords, not requiring immediate intervention. Difficulty swallowing can be expected due to postoperative swelling or edema, but it should be monitored closely. A temperature of 100.2°F is a mild fever and may be a normal postoperative response, not necessitating immediate intervention unless accompanied by other concerning symptoms.

4. A client is scheduled for a colonoscopy. Which instruction should the nurse provide?

• A. Eat a light breakfast on the day of the procedure.
• B. You will need to drink a bowel preparation solution before the procedure.
• C. Avoid all liquids for 24 hours before the procedure.
• D. You can continue taking your blood thinners until the day of the procedure.

Correct answer: B

Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.

5. The nurse is caring for a client with a history of deep vein thrombosis (DVT) who is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Prothrombin time (PT) is monitored to ensure therapeutic levels of warfarin and prevent bleeding complications.
