ATI Pathophysiology Final Exam
1. What are direct effects of antibodies? (Select all that apply):
- A. Neutralization
- B. Agglutination
- C. Precipitation
- D. Phagocytosis
Correct answer: A, B, C
Rationale: The direct effects of antibodies include neutralization, agglutination, and precipitation. Antibodies neutralize pathogens by binding to them and preventing their harmful effects. Agglutination involves the clumping together of pathogens, making it easier for phagocytes to engulf them. Precipitation refers to the process where antibodies bind to soluble antigens, forming large complexes that are easily removed from the body. Phagocytosis, on the other hand, is an indirect effect of antibodies where phagocytes engulf and destroy pathogens opsonized by antibodies, not a direct effect.
2. When a nurse assesses a client's IV catheter insertion site and notes a hematoma, which of the following actions should the nurse take? (Select all that apply.)
- A. Stop the infusion.
- B. Apply alcohol to the insertion site.
- C. Apply warm compresses to the insertion site.
- D. Elevate the client's arm.
Correct answer: C
Rationale: When a nurse detects a hematoma at the IV catheter insertion site, applying warm compresses is beneficial as it can promote healing by enhancing circulation and reducing swelling. Elevating the client's arm helps in reducing edema, which can relieve pressure, pain, and further bleeding in the hematoma area. Stopping the infusion may be necessary in certain situations, but it is not a standard action for all hematoma cases. Applying alcohol to the insertion site is discouraged as it can cause irritation and may not aid in resolving the hematoma.
3. The healthcare provider is planning care for a patient receiving morphine sulfate via a patient-controlled analgesia pump. Which intervention may be required due to a potential adverse effect of this drug?
- A. Administering a cough suppressant
- B. Inserting a Foley catheter
- C. Administering an anti-diarrheal
- D. Monitoring urinary output
Correct answer: B
Rationale: Morphine can lead to urinary retention and urinary hesitancy. If a patient shows signs of bladder distention or inability to void, the healthcare provider should be notified, and urinary catheterization may be necessary. Administering a cough suppressant or an anti-diarrheal is not typically required to address adverse effects of morphine. Liver function tests (LFTs) are not directly related to the potential adverse effects of morphine on the urinary system.
4. Which of the following diagnostic tests may be performed to determine if a client has gastric cancer?
- A. Barium enema
- B. Colonoscopy
- C. Gastroscopy
- D. Serum chemistry levels
Correct answer: C
Rationale: A gastroscopy is performed to visualize the stomach lining and obtain biopsies to diagnose gastric cancer.
5. Which of the following organs is in the abdominopelvic cavity?
- A. The heart
- B. The trachea
- C. The thymus
- D. The liver
Correct answer: The liver
Rationale: The correct answer is the liver. The liver is located in the abdominopelvic cavity, which is the space between the diaphragm and the pelvic floor. The heart, trachea, and thymus are not located in the abdominopelvic cavity. The heart is situated in the thoracic cavity, the trachea is in the neck region, and the thymus is located in the upper chest. Understanding the anatomical locations of organs is crucial for medical professionals to accurately diagnose and treat patients.
