What is the term used in epidemiology to indicate the frequency of the occurrence of a condition?
- A. Incidence
- B. Prevalence
- C. Relative risk
- D. Odd ratio
Correct Answer: B
Rationale: Prevalence counts everyone with a condition now total diabetes cases snapshot unlike incidence's newbies, risk's ratios, or odds' gambles. It's the epidemiologist's bread-and-butter for chronic burdens, a nurse's gauge of how many need care today.

Which is not a common cause of respiratory symptoms in HIV/AIDS patients?
- A. community acquired bacterial pneumonia
- B. non hodgkins lymphoma
- C. Pulmonary Embolus
- D. CMV
Correct Answer: C
Rationale: Pulmonary embolus isn't HIV's lung usual clots tie to beds, not AIDS' immune dive. Pneumonia, lymphoma, CMV, PCP thrive in CD4's fall; emboli don't care. Nurses chase opportunists first, a chronic breath thief lineup skipping this oddball.
The nurse is arriving at the beginning of her shift and has taken report on four clients on a medical surgical unit. Which client should the nurse see first?
- A. A Client with pyelonephritis with nausea and vomiting
- B. A client with chronic obstructive pulmonary disease with an oxygen saturation of $90 \%$ on room air
- C. A client post vaginoplasty with bright red blood and clots in her catheter
- D. A client post-total abdominal hysterectomy with 9/10 pain
Correct Answer: C
Rationale: Bright red blood and clots post-vaginoplasty scream hemorrhage ABCs prioritize circulation, needing instant check for shock or transfusion. Pyelonephritis nags, COPD's stable at 90\%, pain's urgent but not bleeding. Nurses hit bleeding first, a life-line call in this post-op rush.
The nurse is caring for a 6-year-old child with leukemia who is having an oncological emergency. Which of the following signs and symptoms would indicate hyperleukocytosis?
- A. Bradycardia and distinct S1 and S2 sounds
- B. Wheezing and diminished breath sounds
- C. Respiratory distress and poor tissue perfusion
- D. Intermittent fever and frequent vomiting
Correct Answer: C
Rationale: Hyperleukocytosis, a leukemia emergency with white blood cell counts over 100,000/mm³, causes blood hyperviscosity, leading to venous stasis and microvessel occlusion by blast cells. This results in respiratory distress (from lung infarction or hypoxemia) and poor tissue perfusion (from impaired circulation), critical signs requiring urgent intervention like leukapheresis or hydration. Bradycardia and clear heart sounds don't fit tachycardia might occur from hypoxia, not bradycardia. Wheezing and diminished breath sounds suggest asthma or infection, not hyperleukocytosis's systemic impact. Fever and vomiting are non-specific and less acute here. Nurses recognizing these symptoms prioritize airway and circulation support, aligning with oncology's focus on rapid response to life-threatening complications in pediatric leukemia care.
A 50-year-old male patient has been hospitalized for a wedge resection of the left lower lung lobe after a routine chest x-ray shows carcinoma. The patient is anxious and asks if he can smoke. Which statement by the nurse would be most therapeutic?
- A. Smoking is the reason you are here
- B. The doctor left orders for you not to smoke
- C. You are anxious about the surgery. Do you see smoking as helping?
- D. Smoking is OK right now, but after your surgery it is contraindicated
Correct Answer: C
Rationale: Anxiety's screaming here naming it and asking if smoking helps opens a door to his feelings, not a lecture. Blaming smoking shames him, spiking stress. Citing orders shuts down dialogue. Greenlighting it's reckless nicotine constricts vessels, risking surgical healing, especially post-lung resection. Therapeutic nursing in oncology digs into emotions, guiding patients through fear without judgment, key for pre-op calm.
Erysipelas
- A. responds to erythromycin
- B. is caused strep pneumoniae
- C. results from microorganism exotoxin production
- D. typically occurs on the neck
