1. What is the measure of the number of existing cases of a disease in a specific population at a given time?

• A. Incidence
• B. Prevalence
• C. Mortality rate
• D. Morbidity rate

Correct answer: B

Rationale: Prevalence is the correct answer as it refers to the number of existing cases of a disease in a specific population at a given time. Incidence, on the other hand, refers to the number of new cases of a disease in a defined population over a specific period. Mortality rate is the measure of the number of deaths in a particular population due to a specific cause, while morbidity rate is the frequency of a disease in a specific population.

2. What is the main focus of secondary prevention?

• A. Early detection and treatment
• B. Rehabilitation
• C. Health promotion
• D. Palliative care

Correct answer: A

Rationale: The main focus of secondary prevention is early detection and treatment of disease. This approach aims to identify health conditions in their early stages when they are easier to treat or manage effectively. Choice B, rehabilitation, is more aligned with restoring function after an illness or injury has occurred. Choice C, health promotion, concentrates on educating and empowering individuals to adopt healthy behaviors to prevent the onset of diseases. Choice D, palliative care, is focused on providing comfort and improving the quality of life for individuals with serious illnesses or at the end of life, rather than on early detection and treatment.

3. A 4-month-old child taking digoxin (Lanoxin) has a blood pressure of 92/78; resting pulse of 78; respirations 28, and a potassium level of 4.8 mEq/L. The client is irritable and has vomited twice since the morning dose of digoxin. Which finding is most indicative of digoxin toxicity?

• A. Bradycardia
• B. Lethargy
• C. Irritability
• D. Vomiting

Correct answer: A

Rationale: Bradycardia (abnormally slow heart rate) is a key sign of digoxin toxicity. In this scenario, the child's symptoms of irritability, vomiting, along with the resting pulse of 78 despite being on digoxin, suggest an impending bradycardia due to digoxin toxicity. Lethargy can also be a sign, but in this case, the child is irritable rather than lethargic. Vomiting, though a symptom, is not as specific to digoxin toxicity as bradycardia. Irritability, while present, is not the most indicative finding of digoxin toxicity compared to bradycardia.

4. When caring for a child with Reye's Syndrome, which action should the nurse give the highest priority?

• A. Monitor intake and output
• B. Provide good skin care
• C. Assess level of consciousness
• D. Assist with range of motion

Correct answer: C

Rationale: Assessing the level of consciousness is crucial when caring for a child with Reye's Syndrome. Changes in neurological status can indicate deterioration of the condition, necessitating immediate medical attention. Monitoring intake and output is important but not the highest priority compared to assessing the child's level of consciousness. Providing good skin care and assisting with range of motion are also important aspects of care but take a lower priority than assessing the child's neurological status in this critical condition.

5. A senior high school student, whose immunization status is current, asks the school nurse which immunizations will be included in the precollege physical. Which vaccine should the nurse tell the student to expect to receive?

• A. Hepatitis C (HepC)
• B. Influenza type B (HIB)
• C. Measles, mumps, rubella (MMR)
• D. Diphtheria, tetanus, pertussis (DTaP)

Correct answer: C

Rationale: The correct answer is C: Measles, mumps, rubella (MMR). MMR vaccine is commonly included in precollege physicals to ensure students are protected against these diseases. Choice A, Hepatitis C (HepC), is incorrect as the standard vaccine for hepatitis given in childhood is Hepatitis B. Choice B, Influenza type B (HIB), is not typically administered during precollege physicals but is recommended for younger children. Choice D, Diphtheria, tetanus, pertussis (DTaP), is usually given in early childhood and not typically repeated during precollege physicals.
