A nurse is planning a teaching session for parents of preschool children. Which statement explains why the nurse should include information about morbidity and mortality?
- A. Life span statistics are included in the data.
- B. It explains effectiveness of treatment.
- C. Cost-effective treatment is detailed for the general population.
- D. High-risk age groups for certain disorders or hazards are identified.
Correct Answer: D
Rationale: Including information about morbidity and mortality is important in a teaching session for parents of preschool children because it helps identify high-risk age groups for certain disorders or hazards. By understanding which age groups are more vulnerable to specific health issues, parents can take proactive steps to protect their children and promote their overall well-being. This information also enables parents to recognize signs and symptoms early on, leading to timely interventions and better outcomes for their children's health.

A patient was rushed to the ER because of difficulty in urination. He was diagnosed then as a cse of benign prostate hyperthropy (BPH) and was advised by the doctor to undego transurethral resection of prostate (TURP). Based on the urgency of the surgery, the nurse classifies this condition as:
- A. emergency
- B. C.urgent
- C. elective
- D. required
Correct Answer: B
Rationale: Transurethral resection of prostate (TURP) is a surgical procedure commonly performed to treat benign prostatic hyperplasia (BPH) that is causing significant symptoms such as difficulty urinating. In this case, the patient was rushed to the ER due to the difficulty in urination, which indicates that the condition is causing acute distress and requires prompt intervention. Since the surgery was advised urgently by the doctor, the nurse classifies this condition as urgent. An urgent procedure is one that is necessary within a relatively short time frame to prevent complications or alleviate acute distress, but it is not an emergency that requires immediate intervention.
As part of primary cancer prevention program, an oncology nurse answers questions from the public at health fair. When someone asks about the laryngeal cancer, the nurse should explain that:
- A. Laryngeal cancer is one of the most preventable types of cancer
- B. Inhaling polluted air isn't a risk factor for laryngeal cancer
- C. Laryngeal cancer occurs primarily in women
- D. Adenocarcinoma accounts for most cases of laryngeal cancer
Correct Answer: A
Rationale: Laryngeal cancer is indeed one of the most preventable types of cancer. The primary risk factors for laryngeal cancer include tobacco use (particularly smoking) and excessive alcohol consumption. Therefore, avoiding tobacco products, moderating alcohol intake, and maintaining a healthy lifestyle can significantly reduce the risk of developing laryngeal cancer. Additionally, early detection through regular check-ups and screenings can help in detecting any precancerous or cancerous changes in the larynx, leading to better treatment outcomes and prognosis.
An elderly nursing home resident who has always been alert and oriented is now showing signs of dehydration and has become confused. Which electrolyte imbalance is most likely involved?
- A. Hyponatremia
- B. Hypercalcemia
- C. Hyperkalemia
- D. Hypomagnesemia
Correct Answer: A
Rationale: Hyponatremia is an electrolyte imbalance characterized by low sodium levels in the blood. Sodium plays a crucial role in regulating the body's fluid balance and is essential for nerve and muscle function. Elderly individuals are at a higher risk of developing hyponatremia due to various factors, including medication use, reduced thirst sensation, and impaired kidney function.
