Which of the following is the most common risk factor for the development of ovarian cancer?
- A. Nulliparity
- B. Early menarche
- C. Late menopause
- D. Family history of breast cancer
Correct Answer: A
Rationale: Nulliparity, which refers to never having given birth to a child, is the most common risk factor for the development of ovarian cancer. Women who have never been pregnant have a higher risk of developing ovarian cancer compared to those who have had children. This association is believed to be related to the uninterrupted ovulation cycles that nulliparous women experience, leading to changes in the surface epithelium of the ovary that predispose them to cancer development. Conversely, factors like early menarche, late menopause, and a family history of breast cancer are also associated with an increased risk of ovarian cancer but are not as commonly observed as nulliparity in the general population.
Where should the nurse dispose used wet diaper and gloves?
- A. Green
- B. Red
- C. Black
- D. Yellow
Correct Answer: C
Rationale: Used wet diapers and gloves should be disposed of in a black waste bin. Black waste bins are designated for general waste, which includes non-infectious materials that do not pose a risk of infection to others. Wet diapers and gloves fall under this category as they are considered non-infectious waste. Proper disposal in the black bin helps in maintaining cleanliness and hygiene in the healthcare setting.
A confused client who fell out of bed because side rails were not used is an example of which type of liability?
- A. Felony
- B. Battery
- C. Assault
- D. Negligence
Correct Answer: D
Rationale: Negligence is the failure to take proper care in doing something, which results in harm or injury to someone else. In this scenario, the client falling out of bed because side rails were not used indicates a lack of proper care or attention by the staff or caregiver responsible for the client. It shows a failure to protect the client from harm, which aligns with the definition of negligence. This situation does not fit the definitions of a felony, battery, or assault.
A patient with chronic obstructive pulmonary disease (COPD) presents with increased dyspnea, wheezing, and productive cough. Which of the following medications is most appropriate for bronchodilation and symptom relief in this patient?
- A. Albuterol (salbutamol)
- B. Diphenhydramine (Benadryl)
- C. Montelukast (Singulair)
- D. Prednisone
Correct Answer: A
Rationale: Albuterol (salbutamol) is a short-acting beta agonist bronchodilator commonly used for quick relief of bronchoconstriction in patients with COPD. It works by relaxing the smooth muscles in the airways, allowing for easier breathing and improved airflow. The patient's increased dyspnea, wheezing, and productive cough are indicative of bronchoconstriction, and albuterol is the most appropriate medication to provide rapid bronchodilation and symptom relief in this situation. Diphenhydramine (Benadryl) is an antihistamine and not typically used for bronchodilation in COPD. Montelukast (Singulair) is a leukotriene receptor antagonist that may be used in the maintenance treatment of COPD but is not the initial choice for acute symptom relief. Prednisone is a cortic
