Nursing Elites

1. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

2. 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.

3. What should the nurse prioritize when providing discharge instructions to a client with a new colostomy?

• A. Skin care around the stoma site
• B. The schedule for colostomy bag replacement
• C. Techniques for odor control
• D. Dietary modifications

Correct answer: A

Rationale: Correct answer: Skin care around the stoma site. Proper skin care around the stoma site is crucial for preventing skin irritation and infection, which are common issues for patients with new colostomies. While the schedule for colostomy bag replacement (Option B) is important, it is not the priority during initial discharge instructions. Techniques for odor control (Option C) are relevant but secondary to skin care for a new colostomy. Dietary modifications (Option D) may be discussed later but are not the priority at this stage.

4. Before a client undergoes a Magnetic Resonance Imaging (MRI) scan with contrast, what should the nurse assess?

• A. If the client has any metal implants
• B. If the client has allergies to iodine or shellfish
• C. If the client has a history of claustrophobia
• D. If the client has ever had a similar procedure before

Correct answer: A

Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (Choice B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (Choice C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (Choice D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.

5. A client admitted to the hospital with advanced liver failure related to chronic alcoholism is exhibiting ascites and edema. Which pathophysiological mechanisms should the nurse identify as responsible for the third spacing symptoms? (Select all that apply.)

• A. Portal hypertension.
• B. Sodium and water retention.
• C. Decreased serum albumin.
• D. All of the above

Correct answer: D

Rationale: In advanced liver failure related to chronic alcoholism, ascites and edema occur due to multiple pathophysiological mechanisms. Portal hypertension contributes to the development of ascites by increasing pressure in the portal venous system. Sodium and water retention exacerbate fluid accumulation in the third space. Decreased serum albumin levels lead to reduced oncotic pressure, contributing to the movement of fluid into the interstitial spaces. Abnormal protein metabolism further disrupts fluid balance. Therefore, all of the options (A, B, and C) are correct in this scenario, making choice D the correct answer. Choices A, B, and C alone do not fully explain the comprehensive pathophysiological mechanisms involved in the development of ascites and edema in this clinical context.
