Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?
- A. 0.9% sodium chloride
- B. 5% dextrose in water solution
- C. Sterile water
- D. Heparin sodium
Correct Answer: A
Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

The Token Economy is a type of therapy that focuses on:
- A. play therapy
- B. behavior modification
- C. milieu therapy
- D. associative
Correct Answer: B
Rationale: The correct answer is 'behavior modification.' The Token Economy is a form of behavior modification that involves providing positive reinforcement in the form of tokens or rewards for desired behaviors. This approach aims to increase the occurrence of positive behaviors by rewarding them. Play therapy (choice A) focuses on using play as a medium for therapeutic communication, not specifically behavior modification. Milieu therapy (choice C) involves shaping the environment to promote desired behaviors but is not the primary focus of the Token Economy. 'Associative' (choice D) is not directly related to the Token Economy or its focus on behavior modification, making it an incorrect choice.
How should Lasix be administered to prevent hypotension?
- A. By administering it over 1-2 minutes
- B. By hanging it IV piggyback
- C. With normal saline only
- D. By administering it through a venous access device
Correct Answer: A
Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.
Following the change of shift report, when can or should the nurse alter or modify the plan?
- A. halfway through the shift
- B. at the end of the shift before handing over
- C. when needs change
- D. after the top-priority tasks have been completed
Correct Answer: C
Rationale: The correct answer is 'when needs change.' The nurse should be flexible and adjust the plan as necessary when the needs of the patients change. This ensures that care is provided effectively and efficiently. Choices A, B, and D are incorrect because altering the plan based on time intervals, solely at the end of the shift, or after completing top-priority tasks may not align with the current needs of the patients.
Two staff nurses were considered for promotion to head nurse. The promotion is announced via a memo on the unit bulletin board. The nurse who was not promoted tells a friend, "Oh, well, I really didn't want the job anyway."? This is an example of:
- A. rationalization.
- B. denial.
- C. projection.
- D. compensation.
Correct Answer: A.
Rationale: This is an example of rationalization, specifically the sour grapes form, where the individual convinces themselves that they didn't want something after realizing they couldn't have it. Rationalization is an unconscious form of self-deception involving making excuses. In this scenario, the nurse is rationalizing her disappointment by downplaying her desire for the promotion. Denial involves ignoring the existence of a situation, which is not demonstrated here. Projection involves blaming others unconsciously, which is also not present in this situation. Compensation is an attempt to offset a perceived weakness by emphasizing a strong point, which is not shown in the nurse's response.
Six hours after birth, the infant is found to have an area of swelling over the right parietal area that does not cross the suture line. The nurse should chart this finding as:
- A. A cephalohematoma
- B. Molding
- C. Subdural hematoma
- D. Caput succedaneum
Correct Answer: A
Rationale: The correct answer is A, a cephalohematoma. A cephalohematoma is an area of bleeding outside the cranium but beneath the periosteum, typically not crossing the suture line. Answer B, molding, is the overlapping of the bones of the cranium and does not involve bleeding, making it an incorrect choice. Answer C, a subdural hematoma, involves intracranial bleeding and is typically diagnosed through imaging studies like a CAT scan or x-ray. Answer D, caput succedaneum, is characterized by edema that crosses the suture line, unlike the described swelling in this case.
