Nursing Elites

1. A 25-year-old woman who works as an air traffic controller presents with facial pain and severe headache. She reports that she sometimes feels the pain in her neck or ear and that it is particularly bad during very busy times at the airport. What is the most likely diagnosis?

• A. Migraine headache
• B. Cluster headache
• C. Temporomandibular joint syndrome
• D. Sinus headache

Correct answer: C

Rationale: The most likely diagnosis for the 25-year-old woman who works as an air traffic controller and presents with facial pain and severe headache that sometimes radiates to her neck or ear, aggravated by stress, is Temporomandibular joint syndrome. This syndrome involves pain in the jaw joint and the muscles controlling jaw movement, which can radiate to the surrounding areas like the neck and ear. Stress and clenching of the jaw commonly exacerbate the symptoms. Migraine headache (choice A) typically presents with other symptoms like nausea, sensitivity to light or sound, and can be triggered by various factors, not just stress. Cluster headache (choice B) is characterized by severe, unilateral pain around the eye with associated autonomic symptoms. Sinus headache (choice D) is usually associated with sinus congestion or infection, presenting with facial pressure or pain, often worsened by bending forward.

2. An 8-year-old boy has been diagnosed with a sex hormone deficiency and has begun a course of treatment with testosterone. What change in the boy's health status would necessitate a stop to the course of treatment?

• A. Excessive growth in height
• B. Signs of puberty
• C. Recurrent urinary tract infections
• D. Increased blood pressure

Correct answer: B

Rationale: In an 8-year-old boy with a sex hormone deficiency being treated with testosterone, the appearance of signs of puberty would necessitate stopping the treatment. Testosterone therapy in this case aims to supplement the deficient sex hormones but should not trigger premature puberty. Excessive growth in height (choice A) is not a typical reason to stop testosterone therapy. Recurrent urinary tract infections (choice C) and increased blood pressure (choice D) are not directly related to testosterone therapy in this context.

3. The registered nurse is teaching a class on inflammation and explains that which cell is the predominant phagocyte arriving early at inflammatory and infection sites?

• A. Macrophages
• B. Mast cells
• C. Monocytes
• D. Neutrophils

Correct answer: D

Rationale: Neutrophils are the correct answer as they are the predominant phagocytes arriving early at inflammatory and infection sites. Neutrophils are part of the body's innate immune system and are among the first responders to sites of inflammation or infection. They play a crucial role in engulfing and destroying pathogens. Macrophages, although important phagocytes, usually arrive later at the site. Mast cells are involved in allergic reactions and not primarily phagocytes. Monocytes are precursors to macrophages and are not the predominant phagocytes arriving early at inflammatory sites.

4. A patient is starting on oral contraceptives. What should the nurse emphasize about the importance of taking the medication at the same time each day?

• A. Taking the medication at the same time each day helps maintain stable hormone levels and ensures effectiveness.
• B. Taking the medication at the same time each day reduces the risk of breakthrough bleeding.
• C. Taking the medication at the same time each day ensures consistent absorption and effectiveness.
• D. Taking the medication at the same time each day is important, but missing a dose occasionally is not a concern.

Correct answer: A

Rationale: The correct answer is A. Taking oral contraceptives at the same time each day helps maintain stable hormone levels and ensures their effectiveness in preventing pregnancy. Choice B is incorrect because the primary emphasis of consistent timing is on hormone levels and effectiveness, not on reducing breakthrough bleeding. Choice C is incorrect because while consistent absorption is a factor, the main focus is on maintaining stable hormone levels. Choice D is incorrect as missing doses can significantly impact contraceptive efficacy.

5. When the body produces antibodies against its own tissue, the condition is called:

• A. Alloimmunity
• B. Opsonization
• C. Autoimmunity
• D. Hypersensitivity

Correct answer: C

Rationale: Autoimmunity is the correct term for a condition where the body's immune system mistakenly targets its own tissues. Alloimmunity (Choice A) refers to an immune response against foreign tissue. Opsonization (Choice B) is a process where pathogens are marked for destruction by immune cells. Hypersensitivity (Choice D) involves an exaggerated immune response against antigens.
