Nursing Elites

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. A 6-month-old infant who is being treated for developmental dysplasia of the hip has been placed in a hip spica cast. The nurse should teach the parents to

• A. Gently rub the skin with a cotton swab to relieve itching
• B. Place the favorite books and push-pull toys in the crib
• C. Check every few hours for the next day or 2 for swelling in the baby's feet
• D. Turn the baby with the abduction stabilizer bar every 2 hours

Correct answer: C

Rationale: The correct answer is to check every few hours for the next day or 2 for swelling in the baby's feet. Swelling in the baby's feet could indicate compromised circulation due to the cast, and frequent checks are necessary to ensure that there are no complications. Choices A, B, and D are incorrect because rubbing the skin with a cotton swab, placing favorite items in the crib, and turning the baby with the abduction stabilizer bar do not address the potential issue of compromised circulation and swelling in the baby's feet.

3. A 16-year-old female client returns to the clinic because she is pregnant for the third time by a new boyfriend. Which vaccine should the nurse plan to administer?

• A. MMR
• B. Hepatitis B
• C. Human papillomavirus
• D. Pneumococcal

Correct answer: B

Rationale: The correct answer is B, Hepatitis B. The Hepatitis B vaccine is crucial for pregnant women to prevent transmission of the virus to the baby during childbirth. Option A, MMR (Measles, Mumps, Rubella) vaccine, is not indicated during pregnancy. Option C, Human papillomavirus vaccine, is recommended for prevention of HPV infections but is not specifically indicated during pregnancy. Option D, Pneumococcal vaccine, is important for certain populations but is not the priority vaccine for a pregnant woman in this scenario.

4. A client is scheduled to have a blood test for cholesterol and triglycerides the next day. The nurse would tell the client

• A. ''Be sure to eat a fat-free diet until the test.''
• B. ''Do not eat or drink anything but water for 12 hours before the blood test.''
• C. ''Have the blood drawn within 2 hours of eating breakfast.''
• D. ''Stay at the laboratory so 2 blood samples can be drawn an hour apart.''

Correct answer: B

Rationale: Fasting for at least 12 hours is necessary before a cholesterol and triglyceride test to ensure accurate results by avoiding fluctuations that can occur after eating. Choice A is incorrect because a fat-free diet is not required; fasting is. Choice C is incorrect as it suggests having the test right after eating, which can affect the results. Choice D is incorrect as there is no need to stay at the laboratory for 2 blood samples unless specifically instructed by a healthcare provider.

5. Which of the following is not classified as an essential health service?

• A. Provision of eye glasses and dentures for the elderly
• B. Maternal and child care
• C. Basic sanitation and prevention and control of locally endemic diseases
• D. Promotion of proper nutrition, adequate supply of safe water, and health education

Correct answer: A

Rationale: The provision of eyeglasses and dentures for the elderly is not classified as an essential health service. Essential health services typically focus on preventive, promotive, curative, and rehabilitative care that address the primary healthcare needs of individuals and communities. Choices B, C, and D are examples of essential health services as they directly contribute to improving and maintaining the health of populations. Maternal and child care, basic sanitation, disease prevention, nutrition promotion, safe water supply, and health education are essential components of public health initiatives.
