Nursing Elites

1. Which structures are located in the subcutaneous layer of the skin?

• A. Sebaceous and sweat glands
• B. Melanin and keratin
• C. Sensory receptors and hair follicles
• D. Adipose cells and blood vessels

Correct answer: D

Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.

2. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). Which symptom should prompt the nurse to notify the healthcare provider?

• A. Weight gain.
• B. Bradycardia.
• C. Nervousness and tremors.
• D. Fatigue.

Correct answer: C

Rationale: The correct answer is C: 'Nervousness and tremors.' In a client with hypothyroidism prescribed levothyroxine, the development of nervousness and tremors may indicate hyperthyroidism, which can result from excessive dosing of levothyroxine. Therefore, the nurse should promptly notify the healthcare provider to adjust the medication dosage. Choices A, B, and D are incorrect because weight gain, bradycardia, and fatigue are more commonly associated with hypothyroidism itself, indicating that the levothyroxine therapy may not be effective enough, rather than being signs of excessive dosing.

3. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?

• A. Determine if the drainage has an unpleasant odor.
• B. Monitor the client's white blood cell count (WBC).
• C. Request a culture and sensitivity of the wound.
• D. Cleanse the wound with a sterile saline solution.

Correct answer: C

Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.

4. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?

• A. Hemoglobin
• B. White blood cell count
• C. Platelet count
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.

5. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
