Human Growth and Development Final Exam
1. In the eighth month of pregnancy, what typically happens?
- A. fetal growth doubles
- B. neuron production increases
- C. the eyes, ears, nose, jaw, and neck form
- D. lanugo typically is shed
Correct answer: D
Rationale: In the eighth month of pregnancy, lanugo typically is shed. Lanugo is the fine, downy hair that covers a fetus's body to help regulate body temperature while in the womb. By the eighth month, many fetuses shed this hair as they prepare for birth. Choices A, B, and C are incorrect because fetal growth doubling, neuron production increasing, and the formation of eyes, ears, nose, jaw, and neck occur in earlier stages of pregnancy, not specifically in the eighth month.
2. Which of the following is considered voluntary turnover?
- A. Desire to leave
- B. Termination
- C. Forced resignation
- D. Floating
Correct answer: A
Rationale: The correct answer is A, 'Desire to leave.' Voluntary turnover occurs when an employee chooses to leave the organization. In this case, it is a direct function of the nurse's desire to leave. Termination and forced resignation are involuntary processes where the decision is made by the employer, not the employee. 'Floating' refers to the reassignment of a nurse to a unit different from their usual work unit and is not directly related to turnover.
3. Which topical antimicrobial is most frequently used in burn wound care?
- A. Neosporin
- B. Silver nitrate
- C. Silver sulfadiazine
- D. Sulfamylon
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. Which vitamin deficiency is commonly associated with prolonged antibiotic use?
- A. Vitamin A
- B. Vitamin B6
- C. Vitamin C
- D. Vitamin K
Correct answer: D
Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, leading to Vitamin K deficiency and an increased risk of bleeding. Vitamin A deficiency is not commonly associated with antibiotic use. Similarly, Vitamin B6 and Vitamin C deficiencies are not typically linked to prolonged antibiotic use.
5. A healthcare professional is preparing to insert an indwelling urinary catheter. What is the most important action to prevent infection?
- A. Use sterile gloves during the procedure.
- B. Clean the catheter insertion site with alcohol.
- C. Insert the catheter as quickly as possible.
- D. Use a smaller catheter size to minimize trauma.
Correct answer: A
Rationale: Using sterile gloves during catheter insertion is crucial to prevent infection. Sterile gloves help maintain asepsis during the procedure, reducing the risk of introducing microorganisms into the urinary tract. Cleaning the insertion site with alcohol, as mentioned in choice B, is important but not as critical as using sterile gloves. Choice C, inserting the catheter as quickly as possible, is not recommended as it can lead to errors and increase the risk of contamination. Choice D, using a smaller catheter size to minimize trauma, is not directly related to preventing infection but rather focuses on patient comfort and reducing tissue damage.
