HESI LPN
Adult Health 2 Exam 1
1. Which organ lies retroperitoneally?
- A. Kidneys
- B. Testicles
- C. Urinary bladder
- D. Pancreas
Correct answer: A
Rationale: The correct answer is A: Kidneys. The kidneys are located retroperitoneally, behind the peritoneum, providing structural protection and maintaining a stable position within the abdominal cavity. This location helps protect them from external physical trauma. Choices B, C, and D are incorrect because testicles, urinary bladder, and pancreas are not located retroperitoneally. Testicles are located in the scrotum, the urinary bladder is located in the pelvis, and the pancreas is located in the upper abdomen, not retroperitoneally.
2. A postoperative client complains of sudden shortness of breath. What should the nurse do first?
- A. Administer oxygen
- B. Call the healthcare provider
- C. Prepare for chest x-ray
- D. Assess the client's lung sounds
Correct answer: D
Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.
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. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?
- A. Muscle weakness
- B. Decreased deep tendon reflexes
- C. Constipation
- D. Hypotension
Correct answer: A
Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.
5. 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.
