Which of the following measures the proportion of the population that exhibits a particular disease at a particular time and includes both new and old cases?
- A. proportionate morbidity rate
- B. case fatality rate
- C. incidence ratio
- D. prevalence ratio
Correct Answer: D
Rationale: The correct answer is D, prevalence ratio. Prevalence ratio measures the proportion of the population with a particular disease at a specific time, including both new and existing cases. Choice A, proportionate morbidity rate, is not a standard term and might confuse students. Choice B, case fatality rate, measures the proportion of deaths from a specific disease compared to the total number of cases but does not include both new and old cases. Choice C, incidence ratio, measures the rate of new cases of a disease in a specific population over a defined period, not considering existing cases.

A client was admitted with a diagnosis of pneumonia. When auscultating the client's breath sounds, the nurse hears inspiratory crackles in the right base. Temperature is 102.3 degrees Fahrenheit orally. What finding would the nurse expect?
- A. Flushed skin
- B. Bradycardia
- C. Mental confusion
- D. Hypotension
Correct Answer: C
Rationale: The correct answer is C: Mental confusion. In this scenario, the client's high fever and pneumonia diagnosis indicate an infection. Infections, especially in older adults, can lead to mental confusion due to the body's systemic response to the infection. Flushed skin (choice A) is more commonly associated with fever but does not specifically relate to the client's condition. Bradycardia (choice B) and hypotension (choice D) are less likely findings in a client with pneumonia and a high fever; instead, tachycardia and increased blood pressure are more commonly seen in response to infection.
While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?
- A. Check vital signs
- B. Massage the fundus
- C. Offer a bedpan
- D. Check for perineal lacerations
Correct Answer: B
Rationale: The correct action for the nurse to take when encountering a boggy uterus and vaginal bleeding after delivery is to massage the fundus. Massaging the fundus helps the uterus contract, which can reduce vaginal bleeding. Checking vital signs may be important but addressing the uterine atony and bleeding takes precedence. Offering a bedpan or checking for perineal lacerations are not the immediate actions needed to manage postpartum hemorrhage.
At a routine health assessment, a client tells the nurse that she is planning a pregnancy in the near future. She asks about preconception diet changes. Which of the statements made by the nurse is best?
- A. Include fibers in your daily diet.
- B. Increase green leafy vegetable intake.
- C. Drink a glass of milk with each meal.
- D. Eat at least 1 serving of fish weekly.
Correct Answer: B
Rationale: The correct answer is B: "Increase green leafy vegetable intake." This is the best advice because green leafy vegetables are rich in folic acid, which is essential for fetal development and helps prevent neural tube defects. Choice A is not specific enough and does not address the importance of folic acid. Choice C, drinking milk with each meal, does not provide the necessary folic acid intake. Choice D, eating fish weekly, is not as crucial for preconception diet changes as increasing folic acid intake.
In the immediate postoperative period for a cleft lip repair in a 2-month-old infant, which nursing approach should be the priority?
- A. Remove protective arm devices one at a time for short periods with supervision
- B. Initiate oral feedings when alert
- C. Introduce the parents to the suture line cleansing protocol
- D. Position the infant on the back after feedings throughout the day
Correct Answer: A
Rationale: The correct nursing approach in the immediate postoperative period for a cleft lip repair in an infant is to remove protective arm devices one at a time for short periods with supervision. This approach helps prevent injury to the surgical site while ensuring the infant's comfort and safety. Choice B is incorrect as initiating oral feedings immediately after surgery may not be appropriate and could compromise the surgical site. Choice C is incorrect as introducing parents to the suture line cleansing protocol is important but not the immediate priority. Choice D is incorrect as positioning the infant on the back after feedings is not specific to the immediate postoperative period for a cleft lip repair.
As a supervisor, you plan to conduct a seminar in response to the midwife's training need for skills in community diagnosis. Which is an appropriate method to use to enable midwives to apply the knowledge they will gain in actual practice?
- A. lecture
- B. problem-solving
- C. group discussion
- D. nominal group technique
Correct Answer: B
Rationale: Problem-solving is an effective method to enable midwives to apply the knowledge gained in actual practice. By engaging in problem-solving activities during the seminar, midwives can enhance their critical thinking skills and directly apply the information to real-life scenarios they may encounter in community diagnosis.
Choice A (lecture) is less effective as it primarily involves passive listening and may not provide the hands-on experience needed for practical application. Choice C (group discussion) can be helpful for sharing perspectives but may not directly translate to practical application as problem-solving would. Choice D (nominal group technique) focuses more on generating ideas and reaching consensus rather than hands-on application of knowledge.
