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. The nurse is palpating the right upper hypochondriac region of the abdomen of a client. What organ lies underneath this area?

• A. Duodenum
• B. Gastric pylorus
• C. Liver
• D. Spleen

Correct answer: C

Rationale: The correct answer is C: Liver. The liver is located in the right upper hypochondriac region of the abdomen. The duodenum (Choice A) is located in the right upper quadrant but not directly underneath the right upper hypochondriac region. The gastric pylorus (Choice B) is part of the stomach and is located more centrally in the abdomen. The spleen (Choice D) is located in the left upper quadrant of the abdomen, not underneath the right upper hypochondriac region.

3. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.

4. A 4-year-old with acute lymphocytic leukemia (ALL) is receiving a chemotherapy protocol that includes methotrexate, an antimetabolite. Which information should the nurse provide the parents about caring for their child?

• A. Use sunblock or protective clothing when outdoors.
• B. Include the child in regular outings with the family.
• C. Obtain any childhood vaccinations that are not up-to-date.
• D. Use diluted commercial mouthwash for mouth care.

Correct answer: A

Rationale: The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.

5. 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.
