Nursing Elites

1. A male patient is being treated with testosterone gel for hypogonadism. What important instruction should the nurse provide?

• A. Apply the gel to the face and neck for maximum absorption.
• B. Apply the gel to the chest or upper arms and allow it to dry completely before dressing.
• C. Apply the gel to the scalp and back.
• D. Apply the gel to the genitals for improved results.

Correct answer: B

Rationale: The correct instruction for applying testosterone gel is to apply it to the chest or upper arms and allow it to dry completely before dressing. This is important to prevent the transfer of the medication to others. Applying it to the face and neck (Choice A) is incorrect as these areas are not recommended. Similarly, applying it to the scalp and back (Choice C) or the genitals (Choice D) is also incorrect and can lead to inappropriate absorption or undesirable effects.

2. Which of the following is a common cause of mechanical small intestine obstruction?

• A. Infection
• B. Postoperative adhesions
• C. Tumors
• D. Foreign body

Correct answer: B

Rationale: Postoperative adhesions are a common cause of mechanical small intestine obstruction. Adhesions can form after abdominal surgery, causing bands of scar tissue that may twist or pull the intestines, leading to obstruction. This is a more common cause compared to infection, tumors, or foreign bodies. Infection may lead to inflammation but is not a typical cause of mechanical obstruction. Tumors and foreign bodies can cause blockages but are less common than postoperative adhesions.

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. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?

• A. Crossed-extensor reflex
• B. Flexor reflex
• C. Withdrawal reflex
• D. Stretch reflex

Correct answer: C

Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.

5. A patient is diagnosed with ischemic heart disease. She is prescribed filgrastim (Neupogen). What effect will this medication provide in the treatment of ischemic heart disease?

• A. Increase platelets
• B. Decrease platelets
• C. Promote angiogenesis
• D. Prevent thrombus formation

Correct answer: C

Rationale: Filgrastim (Neupogen) is a medication that promotes the growth of white blood cells. In the context of ischemic heart disease, promoting angiogenesis, the formation of new blood vessels, can improve blood flow to the heart muscle, reducing ischemia and potentially improving cardiac function. Therefore, the correct answer is C. Choices A and B are incorrect because filgrastim does not directly affect platelet levels. Choice D is also incorrect as filgrastim does not prevent thrombus formation.
