Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. Which type of anemia is associated with chronic kidney disease?

• A. Iron-deficiency anemia
• B. Vitamin B12 deficiency anemia
• C. Aplastic anemia
• D. Erythropoietin deficiency anemia

Correct answer: D

Rationale: The correct answer is D, Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates the bone marrow to produce red blood cells. Choices A, B, and C are incorrect. Iron-deficiency anemia is characterized by low iron levels, vitamin B12 deficiency anemia by inadequate vitamin B12, and aplastic anemia by bone marrow failure.

3. Which endocrine disorder would the nurse assess for in the client who has a closed head injury with increased intracranial pressure?

• A. Pheochromocytoma
• B. Diabetes insipidus
• C. Hashimoto's disease
• D. Gynecomastia

Correct answer: B

Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus can develop after a head injury due to damage to the hypothalamus or pituitary gland, leading to a deficiency in antidiuretic hormone (ADH). Pheochromocytoma (Choice A) is a tumor of the adrenal gland that causes excessive release of catecholamines, leading to hypertension. Hashimoto's disease (Choice C) is an autoimmune condition affecting the thyroid gland. Gynecomastia (Choice D) refers to the enlargement of breast tissue in males and is not directly related to a closed head injury with increased intracranial pressure.

4. What is the best position for any procedure that involves vaginal and cervical examination?

• A. Dorsal recumbent
• B. Side lying
• C. Supine
• D. Lithotomy

Correct answer: D

Rationale: The lithotomy position is the most suitable position for procedures involving vaginal and cervical examination because it provides the best access to the vaginal and cervical regions. In this position, the patient lies on their back with their legs flexed and feet placed in stirrups, allowing for optimal visualization and access to the area. This position facilitates proper examination, diagnosis, and treatment when working in the gynecological field. Choices A, B, and C are incorrect as they do not provide the necessary exposure and access required for a thorough vaginal and cervical examination. Dorsal recumbent, side lying, and supine positions may limit visibility and hinder the examination process in such cases.

5. During a respiratory assessment, the nurse is determining respirations per minute. Which factor(s) generally affect the character of respirations? Select all that apply.

• A. Anxiety
• B. Exercise
• C. Smoking
• D. A, B

Correct answer: D

Rationale: The correct answer is D. Anxiety and exercise can significantly alter the character of respirations, increasing the rate and depth. Smoking primarily affects the health of the respiratory system in the long term but may not immediately impact the character of respirations. Therefore, choice C is incorrect. Choices A and B are correct as anxiety and exercise can lead to changes in the rate and depth of respirations.
