1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. Which of the following is an organizational factor that affects workplace violence directed at nurses?
- A. Clients who have short hospital stays
- B. The presence of security guards
- C. Restricted client areas
- D. Understaffing of nursing personnel
Correct answer: D
Rationale: Understaffing of nursing personnel is a critical organizational factor that can contribute to workplace violence directed at nurses. When there are too few nurses on duty due to understaffing, it can lead to delays in care delivery and inadequate attention to clients' needs. This situation can result in heightened frustration, aggression, or violence from clients or their families towards the nursing staff. On the other hand, the presence of security guards (Choice B) may enhance safety in the workplace and deter violence, making it an incorrect choice. Clients who have short hospital stays (Choice A) and restricted client areas (Choice C) are not directly linked to organizational factors that promote workplace violence against nurses, making them incorrect choices.
3. Which desired outcome written by the nurse is correctly written and measurable?
- A. Client will have a normal bowel pattern by April 2
- B. The client will lose 4 lbs. within the next 2 weeks
- C. The nurse will provide skin care at least 3 times each day
- D. The client will breathe better after resting for 10 minutes
Correct answer: B
Rationale: An outcome statement must describe the observable client behavior that should occur in response to the nursing interventions. It consists of a subject, action verb, conditions under which the behavior is to be performed, and the level at which the client will perform the desired behavior. Option B is correctly written and measurable as it includes all the required elements: subject (client), action verb (lose), conditions (within the next 2 weeks), and the level at which the behavior should occur (4 lbs.). Option A lacks the conditions and a specific level, making it not measurable. Option C is a nursing intervention rather than a client goal. Option D does not provide a specific level at which the client should perform the desired behavior, making it not measurable as well.
4. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?
- A. Controls stray electrical currents.
- B. Promotes efficient use of electricity.
- C. Shuts off the appliance if there is an electrical surge.
- D. Divides the electricity among the appliances in the room.
Correct answer: A
Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.
5. While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?
- A. They are able to make simple associations of ideas
- B. They are able to think logically in organizing facts
- C. Interpretation of events originates from their own perspective
- D. Conclusions are based on previous experiences
Correct answer: B
Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.
