In public education on Typhoid fever, the condition mainly spreads through:
- A. Contaminated air
- B. Mineral water
- C. Contaminated food and water
- D. All of the above
Correct Answer: C
Rationale: Typhoid fever is primarily spread through contaminated food and water, usually due to poor sanitation practices. The bacteria responsible for typhoid fever, Salmonella Typhi, is typically found in food or water contaminated by the feces of an infected person. Contaminated air is not a significant mode of transmission for typhoid fever, making choice A incorrect. While waterborne transmission can occur, it is through contaminated water rather than specifically mineral water, making choice B incorrect. Therefore, the correct answer is C, as contaminated food and water are the main sources of transmission for typhoid fever.

How will a ventricular septal defect affect blood flow?
- A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
- B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
- C. No shunting occurs due to high pressure in the left ventricle.
- D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.
Correct Answer: A
Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.
When drawing blood from the diabetic patient for a glycosylated hemoglobin (HBA1c) test, the nurse explains to the woman that the test is used to determine:
- A. The highest glucose level in the past week.
- B. Her insulin levels.
- C. Glucose levels over the past three months.
- D. Her usual fasting glucose level.
Correct Answer: C
Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.
A 3-year-old is seen in the clinic and is diagnosed with an ear infection. The father reports that the child was awake several times during the night, crying. The PRIORITY nursing diagnosis for this child is:
- A. Sleep Pattern Disturbance related to pain.
- B. Pain related to ear infection.
- C. Altered Family Processes related to ill child.
- D. Ineffective Thermoregulation Related to Infection
Correct Answer: B
Rationale: The priority nursing diagnosis for a child diagnosed with an ear infection and experiencing nighttime awakenings and crying would be 'Pain related to ear infection.' Pain management is crucial to ensure the child's comfort and well-being, which can also impact their sleep patterns. Addressing the pain as a priority can lead to improved sleep and overall recovery for the child.
A mother of a 2-year-old child complains that her child has a fever, sore mouth, and red eye. What will be the possible diagnosis?
- A. TB
- B. Meningitis
- C. Measles
- D. Pertussis
Correct Answer: C
Rationale: The correct answer is C, Measles. Measles commonly presents with symptoms such as fever, sore mouth, and red eyes. These characteristic symptoms help differentiate measles from the other conditions listed. Tuberculosis (Choice A) typically presents with respiratory symptoms, Meningitis (Choice B) commonly presents with symptoms like headache, neck stiffness, and altered mental status, while Pertussis (Choice D) is characterized by severe coughing spells. Therefore, in this case, the symptoms described align more closely with measles.
During a well-child visit, a 10-year-old child is found to be above the 95th percentile for weight and reports watching more than two hours of television daily. An appropriate nursing diagnosis for this child is:
- A. Imbalanced Nutrition: More than body requirements
- B. Altered Growth and Development
- C. Ineffective Coping
- D. Altered Family Processes
Correct Answer: A
Rationale: The correct nursing diagnosis for a 10-year-old child who is above the 95th percentile for weight and watches more than two hours of television daily would be 'Imbalanced Nutrition: More than body requirements.' This diagnosis reflects the excessive intake of nutrients compared to the child's energy expenditure, which can contribute to weight gain. 'Altered Growth and Development' (choice B) is not the most appropriate diagnosis in this scenario, as the primary concern is related to nutrition and sedentary behavior rather than developmental issues. 'Ineffective Coping' (choice C) and 'Altered Family Processes' (choice D) are also not relevant to the child's weight status and television habits. Monitoring and addressing the child's dietary habits and sedentary behavior are essential to promote a healthier lifestyle and prevent further weight-related issues.
