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 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

3. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

4. A client with myelogenous leukemia is receiving an autologous bone marrow transplantation (BMT). What is the priority intervention that the nurse should implement when the bone marrow is repopulating?

• A. Administer sargramostim (Leukine, Prokine).
• B. Infuse PRBC and platelet transfusions.
• C. Give parenteral prophylactic antibiotics.
• D. Maintain a protective isolation environment.

Correct answer: D

Rationale: Maintaining a protective isolation environment is crucial during the repopulation of bone marrow post-transplant to reduce the risk of infections. The client's immune system is compromised during this period, making them highly susceptible to infections. By implementing protective isolation measures, the nurse can help prevent exposure to pathogens, safeguarding the client's health and supporting the success of the transplantation.

5. The client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications by the nurse. Which instruction should the nurse include?

• A. Increase your intake of spicy foods.
• B. Avoid lying down immediately after eating.
• C. Consume a high-fat diet.
• D. Drink caffeinated beverages with meals.

Correct answer: B

Rationale: Avoiding lying down immediately after eating is essential in managing GERD as it helps prevent reflux symptoms by allowing gravity to assist in keeping stomach contents down. Lying down can worsen symptoms by allowing acid to flow back into the esophagus.
