PN Exit Exam 2023 Quizlet
1. An older client is admitted to the psychiatric unit for assessment of a recent onset of dementia. The PN notes that in the evening this client often becomes restless, confused, and agitated. Which intervention is most important for the PN to implement?
- A. Ask family members to remain with the client in the evenings from 5 to 8 pm
- B. Administer a prescribed PRN benzodiazepine at the onset of a confused state
- C. Ensure that the client is assigned to a room close to the nurses' station
- D. Postpone administration of nighttime medications until after 11 pm
Correct answer: C
Rationale: Sundowning, a phenomenon where dementia symptoms worsen in the evening, can be managed by ensuring the client is close to the nurses' station for frequent monitoring and quick intervention, if necessary. This reduces the risk of harm and helps manage agitation. Asking family members to remain with the client may not always be feasible and does not address the need for close monitoring. Administering benzodiazepines should not be the first-line intervention for sundowning as it can increase the risk of falls and other adverse effects. Postponing medication administration may disrupt the client's routine and potentially worsen symptoms.
2. What is the function of the enzyme lactase in the digestive system?
- A. Breaks down lactose into glucose and galactose
- B. Breaks down proteins into amino acids
- C. Converts starch into maltose
- D. Breaks down fats into fatty acids
Correct answer: A
Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.
3. An older postoperative client has the nursing diagnosis 'impaired mobility related to fear of falling.' Which desired outcome best directs the PN's actions for the client?
- A. The client will ambulate with assistance every 4 hours
- B. The physical therapist will instruct the client in the use of a walker
- C. The client will use self-affirmation statements to decrease fear
- D. The PN will place a gait belt on the client prior to ambulation
Correct answer: C
Rationale: The correct answer is C. Using self-affirmation statements helps the client reduce fear and regain confidence in mobility, which is essential for improving impaired mobility. Choice A focuses more on the frequency of ambulation rather than addressing the fear of falling. Choice B involves the physical therapist and the use of a walker, which may not directly address the client's fear. Choice D is a safety measure but does not specifically target the client's fear of falling.
4. A client with blood type AB negative delivers a newborn with blood type A positive. The cord blood reveals a positive indirect Coombs test. Which is the implication of this finding?
- A. The newborn is infected with an infectious blood-borne disease
- B. The newborn needs phototherapy for physiologic jaundice
- C. The mother's Rh antibodies are present in the neonatal blood
- D. The mother no longer needs Rho immune globulin injections
Correct answer: C
Rationale: A positive indirect Coombs test indicates that the mother's Rh antibodies have crossed the placenta and are present in the neonatal blood, which can lead to hemolytic disease of the newborn. This finding necessitates close monitoring and potential intervention. Choice A is incorrect because a positive Coombs test does not indicate an infectious blood-borne disease. Choice B is incorrect as phototherapy for physiologic jaundice is not related to a positive Coombs test result. Choice D is incorrect because a positive Coombs test does not indicate that the mother no longer needs Rho immune globulin injections; in fact, it suggests a need for further management to prevent hemolytic disease of the newborn.
5. What is the most effective way to communicate with a patient who has expressive aphasia?
- A. Asking yes or no questions
- B. Encouraging the patient to write responses
- C. Using picture boards or communication cards
- D. Speaking slowly and clearly
Correct answer: C
Rationale: The most effective way to communicate with a patient who has expressive aphasia is by using picture boards or communication cards. These tools allow patients to convey their needs and responses more effectively when they struggle to speak. Using picture boards or communication cards (Choice C) is preferred as it provides a visual aid to support communication. Asking yes or no questions (Choice A) may limit the patient's ability to express themselves fully. Encouraging the patient to write responses (Choice B) may not be suitable if the patient also has difficulty writing due to the aphasia. While speaking slowly and clearly (Choice D) is important, it may not be sufficient to overcome the communication challenges faced by patients with expressive aphasia.
